Can kidney beans be planted in July?

Kidney beans are suitable for planting in temperate and tropical high altitude areas, with cold tolerance and light tolerance. Kidney bean is a thermophilic plant, and its suitable growth temperature is 15 ~ 25℃, and the suitable temperature for flowering and pod setting is 20 ~ 25℃. Low temperature below 10℃ or high temperature above 30℃ will affect its growth and normal pollination and pod setting.

The soil requirements are not as strict as other crops, and planting on sloping land and cultivated land with low fertility is better than other crops. Can be planted singly, can also be intercropped with other crops, can be replanted, occupies less land, and does not compete with large crops for land and time. Multiple cropping index is high. In the case of limited land area, the advantages of intercropping and interplanting can be used to fully expand the planting area.

Sow in spring all the year round, from early April to early May. Wheat should be sown in summer immediately after harvest, and the earlier the better. No later than the beginning of July. It is necessary to do a good job in soil preparation and fertilization, and apply appropriate farmyard manure before sowing. If there is no farmyard manure, apply a small amount of phosphate fertilizer in combination with sowing. Reasonable close planting, disease prevention and seedling protection, intertillage and weeding, timely harvest, prevent bud mildew and improve yield and product quality.

Breeding method of kidney bean

1, seed selection

Before sowing and raising seedlings, the seeds should be selected first. After kidney beans emerge, they are generally not thinned. In order to ensure the whole seedling, we should choose seeds with luster, full seeds, no disease spots, no moth-eaten and no mildew, and pick out inferior seeds with poor maturity, shrinkage and moth-eaten to improve seed purity.

2, soaking seeds to accelerate germination

In order to improve the yield of kidney beans in the early stage of pod setting, it is necessary to soak the seeds with 0.0 1%-0.03% ammonium molybdate solution 10 minute. Germination can be accelerated after soaking seeds. First, the seeds are wrapped in wet cotton cloth and put in an environment of 20-25℃ to accelerate germination. After 2-3 days, most bean seeds will germinate.

3, seedbed preparation

Seeding and seedling raising can be carried out after accelerating germination. Seedling raising of kidney beans is carried out in a seedling tray. Because kidney bean seeds are larger and seedlings are stronger, we should choose a larger seedling tray with 32 holes to raise seedlings. Nutrient soil can be prepared with decomposed organic compost and garden soil in the ratio of 4: 1. After the seedling tray is filled with nutrient soil, put the seedling tray neatly on the seedbed, water it 1 time, and then sow.

Step 4: Sowing.

According to the situation of accelerating germination of kidney bean seeds, put 2-3 seeds in each seedling hole, less seeds with good germination potential and more seeds with poor germination potential 1-2, but at least 2 seeds should be put in each seedling hole, so as to ensure the yield of kidney bean. After sowing, cover the soil 1.5-2 cm thick. In order to ensure the temperature needed for seedling stage, a small arch shed should be built on the seedbed.
