The selection of improved varieties At present, the pea varieties in our province are "Zhong No. 6" and "Zhong No. 4", and dry land and two cooked areas can be planted "Zhong No. 2". "Zhong lang 6" and "Zhong pea No. 4" came into the market early and their merchandise was good; "Zhong ye No. 2" had a slightly later listing period with higher output. Appropriate sowing based on many years of practice shows that the best sowing dates of winter pods for early maturing peas in our province are: November 20-25 in northern Zhejiang, November 25-30 in central Zhejiang, and early December in southern Zhejiang. During the period of sowing, the number of pods per plant, single pod weight, grain weight and fresh pod yield can reach the highest. If sowing early, due to the early high temperature, peas in advance jointing, when encountered low temperature, prone to frost damage; if sowing too late, peas vegetative growth in low temperature conditions, lack of growth, low yield, but also delayed the sale period. For the field where peas are sown late due to the delay in the harvesting of the previous crop, germination can be used to sow the peas 15-20 days earlier. The specific method is: immerse pea seeds in clean water at 15-20°C, remove enough water and other seeds, and sow at the temperature of about 20°C for 2-3 days after sowing. Late rice and single-season paddy fields are planted first, then 1.5 to 1.7 meters wide rakes are made, and the mud is spread evenly over the seeds, covering 1-1.5 cm thick soil. The ditch is 20 cm wide, and the main ditch and ditch are 30 cm deep and 30 cm wide. This fall and winter drought, the climate, soil are relatively dry, such as drought when sowing, should be timely irrigation horse water after sowing, should not flood irrigation, water to the afternoon of the same day, drain the ditch the next morning. Narrow rows of closely planted early-maturing peas are suitable for dense planting. Due to the sprawl of old local varieties, 100-grain weight is also low, only 4-5 kg ​​per mu. Precocious peas should be doubled for each mu. See “Peas 6” for 10 kg, “Zhong 4” for 9 kg, sowing 30-35 cm, and 10-15 cm. Points 2-3 tablets. Can also be broadcast all over the field, a basic seedlings per acre of 33.5 million. The principle of fertilizing the early fertilizing peas in science is to apply the basal fertilizer, reapply the pod fertilizer, and increase the application of phosphorus and potassium fertilizers. Among them, base fertilizer accounted for 50%, manure fertilizer accounted for 35%, and topdressing accounted for 15%. The medium fertility plot Mushi standard fertilizer 2000-2500 kg, before the planting into the decomposed organic fertilizer (not bar fat) 1000 kg, 25-30 kg of phosphate fertilizer, potassium fertilizer 10 kg, or compound fertilizer 75 kg, coke ash or fertilizer Earth 2000-2500 kg. In order to prevent pea sprouts from prospering before spring, they are generally not applied top dressing until the end of January. After the beginning of the “Spring”, Mu Shi applied 250 kg of manure and 2-3 kg of ammonium bicarbonate. In the early stages of flowering and podging, it is necessary to re-apply the glutinous fertilizer and apply 10-12.5 kg of urea per mu. The filling period depends on the length of the bean seedlings and the granulation fertilizer. Weeding and disease prevention Before weeding, we spray 50% acetochlor 60-75 ml or Niles 45 ml water 40-45 kg evenly to prevent weeds. The diseases that damage peas are mainly root rot and blight, which can be controlled by chlorothalonil. The gully drained peas are dry land crops and have underdeveloped root systems. Avoid planting on plots with poor ventilation and high water levels. After sowing, it is necessary to open a ditch so that the ditch will stop raining and dry. In the middle and late periods (April-April), due to the high rainfall, the activity of pea roots was reduced. In order to do a good job of clearing drainage, attention should be paid to avoid premature aging caused by the high groundwater level. China Agricultural Network Editor
