Restaurant peas are also known as Dutch beans, Dutch beans, leguminous peas. There are two types of dwarfs and creepers, like cool and humid climate, cold and heat-resistant. The optimum temperature for growth is 18-20°C. Fresh peas are long-day plants, and strong light and long days favor flower bud differentiation and increase yield. Strict requirements on the soil, but with loose soil, sandy loam or loam soil rich in organic drainage is better, the optimal pH value is 6.0 to 7.2, avoid continuous cropping. Currently cultivated varieties are Taizhong No. 11 and Taizhong No. 11 improved 603#, 604# and other medium-maturing species (120-130 days for the whole growing period, generally 500-600 kg per mu) and sweet peas (full-growing period 130? 140 days, the general yield of 750? 1000 kg). The cultivation techniques are as follows: 1. Suitable sowing time. Sowing should be considered so that during the flowering season, the high temperature above 25°C and the low temperature below 9°C are avoided, and high temperature and rainy weather are avoided. General low-altitude area autumn sowing in mid-August, late winter sowing in late November; middle altitude autumn sowing in early August, winter sowing in mid-November; mid-high altitude autumn sowing in late July, winter sowing in late October In mid-November. Second, choose the land for planting. The best rice field, sweet potato and other non-legume crops followed. Apply enough base fertilizer, 30 kg of Mushi compound fertilizer for full-layer fertilizer, if the concentration of fertilization in the ditch, the fertilizer should be more than 15 cm from the seed. 70 cm wide (80 cm sweet peas), 30 cm wide. Single row seeding, 10 cm seeding 3 species (4 cc sweet peas), seed granules 1.5 kg per mu seedlings, seedling rate of 90%, basic seedling 18,000 seedlings (1.3 to 1.4 million seedlings of sweet peas) . The sowing depth is 2 cm. After sowing, the soil is used for composting. After the seed is planted, 100 grams of butachlor and 50 kg of water are sprayed on the surface to reduce the emergence of weeds. Third, fertilizer and water management. The Dutch bean must be used to produce Miao Fei, suitable for flower manure. The first time after the seedlings are 2-3 leaves, the top dressing will be applied. 500 kilos of thin human waste or 500 kg of urea will be added to the water, and 500 kg of water will be applied every 5 to 7 days. Seedling fertilization. In order to promote seedlings and branching, four leaves were sprayed with paclobutrazol (1 gram of water per gram of paclobutrazol powder). Before the closure of the seal line, the ditch was opened on the side of the hole, and the Mushi compound fertilizer was 25-30 kilograms. The fertilizer was applied once every 7-10 days during the picking period, and 5 kilograms of compound fertilizer was used each time. Spraying 5-25 mg/L alpha-naphthylacetate during flowering can increase the fruit setting rate. During the scab phase, 100 g potassium dihydrogen phosphate plus 50 g of borax and 50 kg of water are sprayed 2-3 times, or the light fertilizer Gao Lida is used. The Dutch bean special type 1500 times sprayed 2-3 times. Fourth, cultivating weeds, cuttings cited vines. Weeding front view weeds combined with small earth. Weeding and weeding 1?2 times. After cutting and sealing, weeds can be used to eradicate weeds with new seedling herbicides such as Gacao Ling or Wei Ba. Extend the vines in time to insert the vines (about 20 days after the autumn sowing, about 30 days after the winter sowing). Seedlings avoid water, drought should be timely irrigation to meet the drought during the flowering season to keep the surface wet, in case of heavy rain to clear the gutter drainage. Fifth, timely harvest. 8-12 days after flowering, picking, grasping the seeds began to form, according to the light to see the grain traces, bean pods turn dark color picking is appropriate. Should be light or using scissors to prevent pulling the stems and keep the flowers intact. Usually 2 days.
