Winter peas can achieve "green winter" and increase income. At present, it is in the winter sowing period of peas. The planting techniques are now described as follows: Proper sowing: The varieties of early-maturing peas cultivated in our province are mainly “Zhong No. 6†and “Zhong No. 4â€. The growth period of these two cultivars is basically the same, and the winter sowing period is about 140 days. The best sowing date for winter peas is in mid-November in northern Zhejiang, late November in Zhejiang, and early December in southern Zhejiang. Early sowing, the plants are vulnerable to low temperature hazards, leading to jointing before spring; sowing late, the vegetative growth period is shortened, the yield decline. Reasonable dense planting: Early-maturing peas stand upright and suitable for dense planting. Generally sowing about 10 kilograms per acre, spacing 30-35 cm, 10-15 cm from the hole, sowing 2-3 per hole. Can also be drilled, but pay attention to uniform seeding, control the basic seedlings per acre of about 40,000. Scientific fertilization: General base fertilizer Mushi compound fertilizer imports 40 kg. Due to the "U" type temperature change during the growth period of winter pea peas, in order to prevent prolonged growth before spring, jointing in advance, the fertilizer should not be topped before the end of January. After the temperature rises around “Lichuâ€, 6 kg of urea was applied as top dressing. In the early stage of flowering and pod formation, about 15 kilograms of urea per acre was used as a flower manure fertilizer to promote flowering, scab, and increase yield. Drum period can be used potassium dihydrogen phosphate 100 g watered 40 kg sprayed 2-3 times to prevent premature aging plants. Weeding and exterminating: Peas are bogey water and afraid of drought crops. Winter sowing peas during the growth of more rain, easy to cause waterlogging, so should be open before the planting of deep trenches, building sorghum, peas in time to clear the gutter drainage. Try to avoid planting peas in fields with high groundwater levels and in muddy fields. Pea field chemical weeding, before sowing can be used before sowing mu 50% acetochlor 60 ml or 20% Napropamide 200 ml watered 40-50 kg evenly spray. The soil is required to be moist when spraying to improve the efficacy. For fields with bad weeding effect or failure to timely weed control, grasses and weeds can be used for stable killing, covered grasses can be used for treatment, and broad-leafed grasses can be used for treatment. Leafminers, cabbage caterpillars, leafhopper moths and aphids are the main pests of peas and can be controlled 2-3 times at seedling stage with 40% dimethoate 1500 times solution or dichlorvos 1000 times solution. Root rot and blight are mainly transmitted by soil. The prevention and control method is the practice of paddy-upland rotation, and the spraying of chlorhexidine and other pesticides at the seedling stage.
