1, reasonable rotation system and planting season
Pea should avoid continuous cropping, rotate for 4-5 years, and intercrop with tomato, pepper, eggplant and rice to prevent soil diseases. In the south of China, Tomb-Sweeping Day planted seeds a few days before and after.
2. Prepare soil and apply sufficient base fertilizer.
Pea root system is deeply distributed, with many fibrous roots, and the taproot develops early and quickly. Sandy soil or sandy loam with loose soil, rich organic matter and low acidity should be selected. Fine and early fertilization is needed in soil preparation. In the south, base fertilizer was applied around the Spring Festival, and 2000 kg of decomposed organic fertilizer, 30 kg of phosphate fertilizer, 40 kg of compound fertilizer and 50 kg of urea were applied per mu. Then turn the ground and bury the fertilizer in the soil, and make a flat bed 7 days before sowing.
3. Seed selection and preparation before sowing
Select high-quality seeds with large, full and uniform grains, no disease spots, no moth-eaten and no mildew, and then put the selected seeds on the bamboo mat for 2-3 days, turning them every 4 hours, being careful not to put them on the concrete floor to prevent burning germs. Before sowing, seeds should be treated at low temperature. First, the dried seeds should be soaked in clear water for 2 hours and turned up and down. The water consumption is half of the seed volume, so that the seed can fully absorb water. After the seed coat swells out, it should be taken out and wrapped in gauze or towel, and watered with clear water every 2 hours. After 20 hours, when the germ of seeds is exposed, they should be put in the refrigerator and kept at a low temperature of 0-2 degrees. 36860.68868888666
Step 4: Sowing.
In the prepared border, row sowing or hole sowing is adopted, with row spacing of 20cm, plant spacing of 3cm or hole spacing of 8cm, and each hole is sown with 2-3 seeds. After sowing, cover a layer of soil with a thickness of 4cm and compact it, so that the seeds can fully contact with the soil, absorb water and preserve moisture.
5. Fertilizer and water management
After peas emerge, intertillage and weeding should be carried out in time. The first intertillage is within 20 days after sowing, and the depth is 8- 10 cm. In the future, depending on whether the soil is hardened or not, dilute fertilizer 1000 kg and urea 2 kg should be applied per mu after intertillage. The water management of edible pea seedlings requires that the soil moisture should be kept moist frequently, which is beneficial to Miao Zhuang and the seedlings are tender and tidy.
6, timely harvesting
About 30 days after sowing, the pea seedling height is 16- 18 cm. When the leaves are 8- 10, new shoots are picked once every half month, which can be harvested for about 8 times continuously, and the yield per mu is 1500 kg.
