Light requirements are not very strict, but flower bud differentiation can be promoted under long-day and low-temperature conditions. Provide sufficient light during growth. Moisture content requires moderate humidity, soil moisture is 70% of the maximum water holding capacity in the field, and suitable air relative humidity is about 60%. First, the type of species 1. Use type The flesh of pods is mainly edible. It can also be used to eat beans or young shoots. It is commonly known as Dutch beans. The seed matures are covered with seeds without cracking. 2. Grain type The endocarp of the capsule has been hardened before the hypertrophy and cannot be eaten. It is mainly eaten as a bean, and when it matures, the capsule breaks down, and most of it is a hard-to-eat and semi-herbaceous variety. 3. Young shoot type Most of the varieties used for bean seedlings are thick and thick, and the leaves are large and thick, with strong growth and many branches. Second, the main varieties Pea peas About 2 meters tall, strong growth, strong branching. The stems and leaves are green, tender and emerald green, English length 10 to 20 cm, width 2.5 cm or so, weight 6 to 7 grams, each seed has 6 to 7 capsules, 1000 grain weight of about 300 grams, in the late. The first flower was born in 14-15 knots and was purple. Spring and summer sowing can be harvested for 60 days or so, but autumn sowing takes about 120 days to harvest. Sweet peas Plant height 1.5 to 2 meters, green leaves, white flowers, pods 7 to 8 centimeters in length, two knots per inflorescence, each seed has 5 to 6 capsules. The tender and juicy meat is thick and sweet, crispy and suitable for raw and cooked food. It can be sowed from March to August. Third, the cultivation season Forbidden continuous cropping of beans, at least two years apart, the best pre-made rice fields or onions and garlic, melons, 9-10 October sowing, the next year 2 March to market. Sowing in spring and summer, from May to September. Fourth, cultivation technology 1. Soil fertigation Before harvesting, the stalks should be ploughed in a timely manner. Every 667 m 2 of organic fertilizer 2000-3000 kg or 40 kg of compound fertilizer is used as the base fertilizer. After fertilization, the soil is smashed and the soil is finely grounded. Autumn sowing can be made into flat stalks. Small sorghum should be made for drainage. 2. Planting density For each 667m 2 seed consumption 5-7kg, the seed should be disinfected. Each kilogram seed is disinfected with 50% of the 0.5% enemy dexamethasone WP to prevent seedling rot disease. In spring and summer, the growing conditions are weak, and the spacing can be 40-50 cm and the spacing is 10 cm; the winter and spring harvests in autumn are very prosperous, and the spacing is 55-60 cm and the spacing is 25-30 cm. Intercropping with corn, planting 2 rows of peas between reserved rows of maize, with 0.4~0.43 meters of row spacing, 0.93~0.9 meters of row spacing, and 35 rows per rice row spacing are appropriate. Pure 667 m2 seeding rate of 8 to 10 kg, the number of seedlings to 35,000 to 40,000 strains is appropriate. Seeds of 3 to 4 seeds per hole in live broadcast, after sowing cover soil, such as soil dry water should be promoted as soon as possible to promote seed germination. 3. Field management (1) Weeding and weeding 8 to 10 days after sowing, peas emerged one after another, and pea roots developed quickly and quickly. After 20 days, when the two roots had two leaves, the main root had already extended 16 cm. In order to prevent soil growth and promote root growth, the cultivator should be cultivated 2-3 times, and the cultivators should be cultivated. In combination with weeding, the last time the soil was cultivated, the line was stopped and the cultivator was stopped. (2) Irrigation fertilizer 1 watering: pea seedlings have a certain ability to drought, but flowering and podging period can not be water shortage, 3 to 5 months is the high temperature dry early season, 10 to 15 days watering time, summer rainfall conditions are flexible grasp, timely irrigation and drainage . 2 top dressing: peas are leguminous crops, with rhizobia nitrogen fixation. Fertilizer application should master nitrogen, phosphorus and potassium, apply basic fertilizer, apply 667 m 2 of nitrogen, phosphorus and potassium compound fertilizer to 30 kg, and apply 667 m of urea at the third leaf stage to 10 kg of urea for seedling fertilizer. 2 Apply 15 kg of urea. Apply water after application to promote more flowering. (3) scaffolding The creeping species should be allowed to stand on an elevated ground and the dwarf species can take a dwarf. In winter and spring, summer and rainy seasons, stand-ups are easy to fall. Usually, they are built into “human†frames or fences to allow them to climb up. Upper shelves should be kept away from the earliest days, or they will be easily entangled with each other and affect the growth. 4. timely harvest In general, the pods are plump and round, and the pupa have not yet become old. However, when the pods are young, they are the best time for harvesting. Disclaimer: Some articles in this website have been transferred from the Internet.
