High-yield Cultivation Techniques of Winter Pea
Variety selection
Pea can be divided into three types according to the growth habit of stems: dwarf, half trailing and trailing; according to its purpose, it can be divided into tender pod type, grain type and leaf type. Farmers can choose early-to-middle maturity, disease-resistant, high-quality, and high-yield varieties to plant according to market demand.
Fine soil preparation and application of base fertilizer
Pea likes sandy loam with deep soil layer, rich organic matter content and good drainage. Choose fields where the previous crops are not legumes. The late rice should be plowed immediately after harvesting, and 40-50 kilograms of decomposed farmyard manure, 40-50 kilograms of mixed phosphate fertilizer and 2 kilograms of boron fertilizer per acre. After composting, the whole layer is used as base fertilizer, and then the border is raised and the border surface is turned into a turtle-back shape. , Cross ditch and drainage ditch around the field should be well opened in the field.
Reasonable fertilization
During the flowering and pod setting period, the root system has been saprophytic nodules. At this time, the demand for phosphorus and potassium is urgent, and it is also sensitive to micro-fertilizers such as boron and molybdenum. Therefore, during the flowering period, combine soil cultivation and apply 15 kg of high-quality compound fertilizer per mu. It is also possible to apply 25 kg of phosphate fertilizer and 7.5 kg of mixed potassium fertilizer, 0.5% borax or 0.3% molybdenum fertilizer can be sprayed during the initial flowering period; the pod-forming fertilizer should be topdressing outside the root, and 0.5 kg of potassium dihydrogen phosphate 3 mixed with urea can be used. Add 1 package of nucleotides to 120 kg of water and spray, once every 10 days, spray 3 times.
Scientific water
Pea is a crop that loves humidity and avoids waterlogging. Excessive drought or humidity will affect its normal growth. Therefore, it is necessary to keep the soil moist after sowing to facilitate seedlings; during the middle of the growth period, especially during the flowering and pod setting period, more water needs to be absorbed. At this time, there must be a certain amount of water in the field to meet its growth needs; Irrigate the horse water in time, and ditch the water in time when it rains to ensure the normal growth of plants.
