First, the selection of good varieties: optional white flower peas, Zhongwan No. 4, Zhongwan No. 6, Dutch beans, pods and vegetables peas No. 1 and other varieties.
Second, deep ploughing and finishing: peas avoid continuous cropping, the plots of peas must be planted every 4-5 years. Deep ploughing and tidying, according to the characteristics of the cultivar and soil drainage conditions, the stalk width is determined. The vegetable stalk is 1.5 m (Liangou), 2 rows, and the stalk is 2 m (Liangou), 4 rows, and the dwarf cultivar 2.5- 3.5 meters (with ditch) kind of 6 lines.
Third, the application of the base fertilizer: before the sowing, 2500 kg of fermented manure per acre, 25-30 kg of superphosphate, 10-15 kg of potassium chloride, or applied. It can also be applied with 30-40 kg of ternary compound fertilizer.
4. Appropriate sowing: Generally, planting in the middle and late October, line spacing 40 cm, plant spacing 20 cm, 10,000 holes per acre, 2-3 seeds per hole, 5-7.5 kg per mu. The high stalk variety and the seedling variety are properly densely planted. The dish is high-stalked soft-pea peas and high-stalked sweet peas. The row spacing is 70-80 cm and the plant spacing is 30 cm, which is convenient for management and picking. Early-maturing dwarf varieties such as Zhongwan No. 4 and Zhongwan No. 6 were sown in late November, with a seed amount of 10 kg per acre, a row spacing of 30-35 cm, a plant spacing of 10-15 cm, and 2-3 capsules per hole.
V. Field management: Check the seedlings to fill the gaps after emergence, and cultivate and weed 1-2 times. Pay attention to the topdressing of seedlings, especially those that do not apply or apply less base fertilizer. Generally, the compound fertilizer is applied for 5-7.5 kg per mu or 5 kg of urea or 1000 kg of manure and manure. When the high stalk variety rises in the spring and the plant begins to elongate, the small bamboo or branching branches (to the leaves) are inserted between the rows so that the bean plants can grow. Peas are not resistant to water stains, and attention should be paid to clearing ditch drainage in spring. There are many nutrients required for flowering and pod-forming, 7.5 kg of urea per mu and 5 kg of ternary compound fertilizer. The granule stage was sprayed with 1% urea and 0.3% potassium dihydrogen phosphate twice.
Sixth, timely harvest: According to the way of eating to determine the harvest time. Generally, the peas are harvested when the seeds are full at 15-18 days after flowering; the dried peas are harvested when 70-80% of the pods are yellow; the peas (Dutch peas) are harvested 12 to 14 days after the flowering The pea seedlings were harvested at the top of the seedlings at a height of 18 cm after sowing for 30 days; the feed was harvested during the full flowering period; the green manure was turned over in time after harvesting the pods.
