When do you plant adzuki beans?

Question 1: adzuki beans are planted for several months and propagated by sowing. They were collected in August when the pods matured but did not crack. They can be sown with crops, or they can be dried and stored until the next spring. The sowing amount per mu is 5 kg to 6 kg. Because the seed surface has a layer of cutin, it needs to be scalded with boiling water 1 min before sowing, and then soaked in cold water for 24 hours. With the help of thermal expansion and cold contraction, the cutin on the surface of seeds can be destroyed and the germination rate can be improved. Spray a new layer of high-fat film in time after sowing to improve the emergence rate. When seedlings are transplanted once, a new layer of high-fat film is sprayed after transplanting to reduce water evaporation, prevent bacterial infection and improve survival rate. After replanting in the next spring, the annual seedling can be as high as 70 cm or more. The overwintering temperature shall not be lower than 4℃.

Question 2: What is the latest solar term of adzuki bean? Variety selection and seed treatment

Breeding excellent varieties is the basis and key to obtain high yield of adzuki bean, and varieties with large grain size, early maturity and high yield, bright grain color, thin skin and high sand production rate should be selected. Generally, you can choose to plant Dahongpao, Baoqinghong, Yinglun Red, Nanjing Red and Japanese variety Danayan. These varieties have good gloss, good quality, high yield and strong disease resistance. Manual selection of seeds, China Agricultural Network to remove impurities and bad grains, so that seeds can meet the standard of precision on demand. Before sowing, the seeds are dried in the sun for 2-3 days in sunny days, and then coated with seed coating agent before sowing. Shilin Shenbanwang can be selected, and the drug-seed ratio is 65,438+0: 50-60. Sow in the shade.

2. Land selection and rational fertilization

Adzuki bean is a leguminous crop, and its soil requirements are not strict. Sandy loam with good drainage, water and fertilizer conservation and rich organic matter is suitable. Adzuki bean is not tolerant to waterlogging and is relatively barren. We should choose gramineous crops such as corn and wheat, and avoid continuous cropping with leguminous crops, because continuous cropping will aggravate diseases, overgrown weeds, poor root development, reduce nodules and reduce the yield and quality of adzuki beans. When selecting land, we should choose land that has not used long-acting pesticides such as atrazine, soybean sulfuron-methyl, and clomazone. In the previous year, in order to avoid drug damage and unnecessary losses. Adzuki bean has weak ability of arching soil, so it should be carefully prepared, harrowed in early spring, ridged and suppressed in time to keep soil moisture. Apply refined organic fertilizer 100 ~ 150 kg, diammonium phosphate 150 kg and potassium sulfate 50 kg per hectare; Or apply 250 kilograms of 48% potassium sulfate compound fertilizer (where N∶P∶K is 13 ∶ 23 ∶ 12 respectively), which can increase or decrease the fertilizer consumption according to the soil fertility and actual production conditions, and the base fertilizer can be applied all at once to meet the nutritional needs of the whole growth period. In order to control underground pests and rodents, such as root nematodiasis and mole cricket, 10 kg of 5% tert-butyl phosphate granules or 3% phoxim granules can be mixed with applied fertilizers and applied to the soil per hectare.

3. Timely sowing and reasonable close planting.

Adzuki bean is a thermophilic crop, the lowest germination temperature is 8℃, and the optimum germination temperature is 14℃~ 18℃, so it is not suitable to sow early, and the field sowing temperature should be stable above 15℃, and the suitable sowing date is from late May to early June. Ridge planting, ridge spacing of 65cm, plant spacing 10~ 15cm, sowing amount of 45~60kg/ha, sowing on the ridge, sowing depth of 3~4cm, and timely suppression after sowing.

4. Strengthen on-site management

4. 1 spacing, fixed seedlings and intertillage seedlings should be done in time after they are all in place, and the seedlings should be fixed at the first leaf compound stage. We should keep strong seedlings and big seedlings, and pull out weak seedlings. After the emergence of seedlings, combined with the first 1 shovel stroke, it is necessary to dig deep and put less soil to prevent the seedlings from pressing, which is beneficial to improve the ground temperature. The second intertillage was carried out about 1 0 days after the shovel passed. Weed and cultivate the soil before flowering. Pull up 1 second grass in the later stage.

4.2 The adzuki bean was sprayed with foliar fertilizer at the initial flowering stage, and 3 kg of potassium dihydrogen phosphate, 24 small bags of powerful multi-dimensional rooting and seedling strengthening agent (25g per bag) and 24 small bags of high-energy peptide (6g per bag) were applied per hectare, and the water was mixed evenly and sprayed on the leaves. The weight of the liquid medicine is about 500 kg, which can promote the flower bud differentiation of adzuki bean and improve the seed setting rate. At the end of adzuki bean flowering period, plant nutrition regulators such as K-D- plant immune nutrition protein, Green Wild God and CP-PO- plant disease cell repair transfer factor were sprayed according to adzuki bean growth, so as to promote adzuki bean plant growth, increase yield, improve grain color and improve commodity quality.

4.3 Chemical weeding The application of chemical weeding technology saves labor and effort. Herbicides can be selected to kill weeds, such as Jingping Herbicide, Jingcaoke, Huwei, Gaicaoneng, Najing and quizalofop-ethyl. The specific usage shall be carried out according to the instruction and local application practice.

4.4 pest control: adzuki bean root-knot nematode disease, root rot, downy mildew, virus disease, aphid, red spider and other pests and diseases are more serious. Can viral diseases be applied, guanidine? 800g/ha of copper acetate, 40g/ha of 0.5% lentinan aqua, or drugs such as Norick, Virus A, and high-quality mushroom poison to kill stars; Root rot can be caused by mixing 500-800g/ha of dead seedlings, rotten roots and 200-400g/ha of CPPO- plant pathological cell repair transfer factor with 450-500kg of water, and then spraying it evenly on leaves; Fungi and bacteria can be selected for downy mildew, and 60% wet cleaning can be done once ... > >

Question 3: Cultivation techniques of adzuki bean: adzuki bean is an annual leguminous crop, and its previous crop should be selected from gramineous crops such as wheat, corn and sorghum to avoid multiple cropping with leguminous crops, so as to avoid being infected with diseases and insect pests and reducing production. Like soybeans, the rotation mode should be three-zone rotation or four-zone rotation: wheat, jade and beans (adzuki beans); Wheat, wheat and beans (adzuki beans); Wheat, miscellaneous and legumes (adzuki beans); Wheat, wheat, jade and beans (adzuki beans). We should choose barren stubble instead of fertilizer stubble. It can be intercropped with tall crops such as corn, sorghum and sunflower, which can make full use of land and light energy and obtain high economic benefits. It can also be planted in fields, fields and trees. The growth period of sowing and site selection is short. You can plant two seasons a year and harvest in one hundred days. Sowing in early April to early May, opening a bed with a width of 1.3m and a spacing of 33cm, sowing 5-6 seeds in each nest, using 22.5-30kg seeds per mu, and covering 1 fire ash discharged from human and animal manure after sowing. It can be intercropped with other crops, such as sweet potatoes, or planted on idle land in orchards. We should choose hillock and flat land with medium fertility and good drainage, and pay attention to flood prevention in low wetlands. It is best to plow in summer and autumn, carefully level and harrow, and adopt the method of ridging and subsoiling and fertilizing in autumn, which is helpful to improve the ground temperature, prevent drought and drainage, and make the seedlings grow healthily. The following formula can be selected for chemical treatment of weeds before sowing: ① 5% common application agent 1.5L/hm2 (specially used for controlling Solanum nigrum, 5% common application agent 1.0L/hm2). ②48% chlorambucil EC is 3.00 ~ 3.75 liters /hm2. ③ 2.0~2.8L/hm2 of 72% tall EC or 2.0 ~ 2.8L/hm2 of 72% tall EC+0.3~0.4L/hm2 of 70% thiazine (0.8 ~ 1.0L/hm2 butyl ester can be added as appropriate according to the weed base) for chemical weeding. After sowing, the following formula can be selected for chemical treatment of stems and leaves: ① Before the 4-leaf stage of gramineous weeds, 12.5% grab 1.2~ 1.5L/hm2 mixed with 300 kg/hm2 water (which has good control effect on gramineous weeds). ② Use 2.0~3.0L of 5% Pushter per hectare. For plots that have not been chemically weeded, it is necessary to shovel the land manually for 2~3 times as soon as possible after all the seedlings are out, and it will be finished before the ridge is closed. In mid-July and early August, manual weeding was carried out 1 time respectively. Planting adzuki bean is a warm crop, and its seedlings grow slowly because of the low temperature in spring. After emergence, intertillage, weeding and shoveling the soil should be done in time to improve the ground temperature and moisture conservation, promote the development of root system and accelerate the robust growth of seedlings. Before flowering, intertillage for three times, the first time 1 time is carried out when two opposite true leaves are fully unfolded, and the second time is carried out when 1 third compound leaves are fully unfolded; The third time is carried out before the three leaves and three leaves are fully unfolded and ridged to prevent the drought and drainage from lodging. Because the stem of adzuki bean is weak and prone to lodging, the pods below are very low and sometimes touch the ground. In late July, the climate is hot and humid, the field permeability is poor, and the lower pods are prone to mildew. Before the bank is sealed, the bank should be plowed 1~2 times to prevent drought, drainage and lodging. Irrigated adzuki beans need more water during their growth, especially before and after flowering. If it is too dry at this time, the yield will be significantly reduced, so irrigation should be carried out in dry years. Chemical control If the amount of nitrogen fertilizer is too much, the precipitation is heavy, and the top of adzuki bean grows vigorously, chemical control should be carried out to make the plant height less than 80cm to prevent lodging, and paclobutrazol 900g/hm2 can be sprayed during flowering and pod setting. Rust: Use 65% mancozeb 500 times solution to prevent and control it. Brown spot disease and atrophy disease: the diseased plants should be removed immediately and sprayed with carbendazim 1000 times solution 1~2 times per hectare. Pest control: 30g of 70% Amylol water dispersible granule+600ml of 2.5% dimethoate emulsifiable concentrate mixed with water per hectare for control. Control of red spider: per hectare, 750ml of 8% chlorpyrifos EC+30g of 70% Amylol water dispersible granules, 750ml of 40.7% chlorpyrifos EC +24.5% avermectin. Diesel EC 600ml+2.5% DDVP EC 600ml spray water. The maturity of adzuki bean pods is different, and some varieties are easy to fry pods, so they can't wait for all pods to mature before harvesting. Factor The grain can ripen later, so it can be harvested when two-thirds of the pods turn grayish yellow. Because adzuki beans have low pods, they can only be harvested manually and dried in the field. When cutting and drying, spread it every 6 ridges (spread it with a scale), and there should be no uncut adzuki beans under it. They should be dried in the ground for 2-3 days until the pods mature and the seeds become natural ... >; & gt

Question 4: Where is adzuki bean suitable for planting adzuki bean? It has strong adaptability. The soil requirement is not high, it is barren-resistant, clay and sand can grow, and it can be planted in Sichuan and mountainous areas. Both waterlogging and drought tolerance, late planting and early maturity, short growth period and simple cultivation techniques can be used as supplementary crops.

Adzuki beans can be planted as long as they meet the growth requirements mentioned above. Adzuki beans are mainly produced in Jilin, Beijing, Tianjin, Hebei, Shaanxi, Shandong, Anhui, Jiangsu, Zhejiang, Jiangxi, Guangdong and Sichuan.

Question 5: When do adzuki beans bloom? Why don't my plants bloom? In our north, it only opens in late autumn.

Question 6: When is the best time to plant adzuki beans? Most of the growers in Orchid Village are mainly mechanized large-scale adzuki beans. The sowing time should be in June-July, and the sowing depth should be moderate, generally 3-5 cm. Wang also explored a set of successful experiences in seed selection, fertilization and close planting of adzuki beans.

Question 7: How to plant adzuki beans and how many days will they germinate? The cultivation of adzuki beans is basically the same as that of mung beans, and they usually emerge in 6-8 days.

Question 8: Why doesn't my adzuki bean blossom in late autumn in our north?

Now is not the time.
