Parsley planting methods parsley greenhouse planting technology

1, variety selection. There are two types of plate leaf species and wrinkled leaf species, and at present the cultivated varieties around the world are mostly wrinkled leaf species.

2, sowing seedlings. Prepare a good seedbed before sowing. Bed to facilitate drainage and irrigation, the soil is loose and fertile, per acre of manure 2000 kg, 25 kg of calcium superphosphate and grass ash 100 kg, and then turn the soil pounded fine, leveling the bed, make a deep ditch raised beds. Water the seedbed well before sowing, sowing to be uniform, 13-19 grams of seed per mu of field, 6-7 square meters of seedbed. Covered with a layer of fine soil after sowing, in order to cover no seed is appropriate, covered with straw or shade net, moisture conservation and cooling, to promote the emergence of seedlings, after the emergence of seedlings in a timely manner to remove the ground cover, watering in the morning and evening, the general bed is no longer fertilization, the seedlings 5-6 pieces of leaves can be planted to the production field.

3, the ground planting. Before planting tilling fertilizer, per mu of high-quality pile of stable fertilizer 2000-3000 kg, 1000 kg of manure, calcium superphosphate 25 kg, 100 kg of grass ash, turn the soil and mix it well after the border, 4-6 m wide greenhouse to do two raised beds, parsley root regeneration ability is strong, the age of the seedling can be small, according to the greenhouse can be small, according to the greenhouse to vacate the stubble situation in the appropriate period of time, but the planting of the small seedlings is appropriate, planting spacing of 15 cm, 20 cm spacing, planting density of 18 cm per mu. cm, planting density of 18,000 plants per mu.

4, greenhouse management. Prefer warm and cool climate, optimal growth temperature 15-20 ℃, long-term below -2 ℃ there is frost damage. Greenhouse cultivation from the end of October to mid-November, the temperature dropped significantly, it is necessary to buckle the film in a timely manner, sunny days at noon in the shed temperature can be properly cooled ventilation, to the winter cold when the shed with a small arch to keep warm or directly covered with non-woven insulation.

5, fertilizer management. Parsley like moist, pay attention to watering throughout the growth period, keep the soil with more water, but not water. After planting to water the living tree water, about 3 days seedling survival 7 days can sprout new leaves, this time to keep the soil moist, avoid drought. Leaves out of the peak growth period, every 10 days irrigation once thorough water, per mu watering 3, 0 kg urea or foliar spray 0, 3% potassium dihydrogen phosphate, continue to fertilize after harvest to promote growth.

6, plowing and weeding. Watering and fertilization will often appear soil sloughing, so pay attention to the mid-ploughing loosening and weeding, mid-ploughing should be shallow, can not hurt the root system, generally preferred to be carried out after the harvest, easy to operate.

7, pest control. Common disease fruit spot disease, available 400 times the generation of manganese zinc liquid spray treatment; in the case of high temperature and lack of fertilizer, easy to appear physiological diseases, such as boron deficiency is easy to cause cracked stems, etc., should be foliar spraying 0, 2% borax aqueous solution.

8, harvesting: 3-4 months after sowing, when the plant grows to 12 leaves, you can pick leaves on the market. General since the outside of the order of the leaves harvested. Suzhou suburbs of experience is: the heart to stay 4-5 functional leaves, choose the middle leaf picking, every 10 days can be harvested, each picking 2 pieces, picking the base to stay 0, 5-1 cm long petiole, should not be even handle picking and injury to the plant. Yield about 2000 kilograms per mu. Commodity leaves should be bundled and packaged according to standards, labeled with trademarks and sold in a timely manner. Packed with plastic wrap to prevent the leaves from losing water and wilting. Long-distance transportation should also be loaded into a plastic crate, put an appropriate amount of crushed ice to cool down and preserve freshness, and transported in an insulated car (cold caravan).
