Restaurant peas also known as Dutch beans, cut beans, soft pod peas, alpine beans, Huai beans, golden beans, return beans, etc., are legumes. The high-quality, high-quality dishes made from its bean pods, tender shoots, and seedlings are crisp, sweet and delicious, and have a delicious flavor. They are popular with consumers. During the growth process of peas, the uptake of nitrogen, phosphorus and potassium by nitrogen, phosphorous and potassium was the most, potassium was the second, and phosphorus was the least. For every 100 kilograms of fresh bean pods produced, 1.6 kilograms of pure nitrogen, 0.6 kilograms of phosphorus pentoxide, and 1.2 kilograms of potassium oxide are required. The ratio of nitrogen, phosphorus, and potassium is 2.7:1:2. The average mu yield is 750-1000 kg.
Base fertilizer
Autumn seeds are planted from late August to early September. Winter seeds are planted from late October to mid-November. Spring seeds are planted from late February to early March and summers are planted in shady sheds. To choose the pH value of 6 ~ 7.2, loose soil, rich in organic matter, good drainage of sandy loam or clay loam suitable for planting, avoid continuous cropping. When the pH is lower than 5.5, it is easy to cause diseases and reduce the rate of scarring. Per acre applied to fermented and cured animal dung 2000 ~ 2500 kg, urea 10 ~ 20 kg, superphosphate 25 ~ 30 kg, potassium sulfate 30 ~ 40 kg or plant ash 100 ~ 200 kg, manganese sulfate 0.5 ~ 1 kg base fertilizer. Each ridge is 0.8 to 1 meter wide and 20 to 25 centimeters high. The sculpted surface is shaped like a turtle, and a cross-shaped groove and ring field drain are opened in the field. Seeds are lightly sunlit for 1 to 2 days before sowing. After cooling, the seeds are cleaned with 28% saline, then rinsed with water and soaked for 1 to 2 hours. After the seeds are fully absorbed, they are soaked with 15 to 17 grams of rhizobia and then sown. Enhance nitrogen fixation. China Agriculture Network recommends double rows of planting, with a row spacing of 8 to 10 cm for 50 cm, 2 to 3 seeds per hole, 7.5 to 8 kg for mu, 2 to 3 cm sowing depth, and soil cover after sowing Species.
2. Dressing
During the early vegetative growth stage of peas, the absorption of nutrients is low, and excessive application of nitrogen will delay the nodule formation and cause the stems and leaves to grow too luxuriantly to cause flowering and falling down; but insufficient supply of nitrogen during the harvest period will lead to a shortened harvest period and lower yield. . After flowering and sitting in lotus root, it will grow rapidly, and the amount of absorbed nutrients will also increase substantially. The application of phosphorus and potassium fertilizers can promote the formation of root nodules, prevent plant growth and increase disease resistance.
1 Shi Qin Qin Miao Fei early. In general, quick-acting nitrogen fertilizers are mainly used to promote branching of plants, increase the number of flowers, and increase the rate of scarring. The main root of pea develops early and rapidly. Before the seedlings have been unearthed for 6 days after sowing, the main roots will elongate 6 to 8 centimeters; when the seedlings have been unearthed 10 days after sowing, there are more than 10 thick roots; 20 days have just started two complexes. Leaves, main roots up to about 16 cm long. After 3 to 4 days after seedlings, 2 to 4 kg of urea per acre will be applied to water, or 20 to 30 kg of water will be applied to decomposed human excreta, and 100 to 120 kg of water will be applied. The second top dressing will be applied every 8 to 10 days. 3.5 to 4 kg of compound fertilizer per acre, 1 to 2 kg of potassium sulfate, 750 to 1 000 kg of water, or 50 to 100 kg of rotten human and animal manure and 4 to 5 kg of urea per mu; Sprayed with paclobutrazol 1 time, 1 kg of water per gram of paclobutrazol powder. When the height of the seedling is 7 to 10 cm, the first cultivating and weeding will be carried out. The height of the seedling is 15 to 16 cm and the third time is combined with large earth to carry out the third top dressing. The ternary compound fertilizer 10 to 15 kg and the potassium chloride 5 to 5 will be buried in the trenches. 7.5 kg. About 50 days after sowing, the seedling height is 20 to 30 cm. When the stems are not yet rapidly evolving, the second time weeds are planted. According to the growth of the weeds, we can flexibly grasp the third weeding time. After the flowering period, the lush stems and leaves will no longer be weeding. More manual removal of weeds. About 30 days after sowing, the period of vines is extended, and the soil is thin, the base fertilizer and the seed fertilizer are insufficient, and the growth of the seedlings is poor. The use of human and animal wastes per acre is 750 to 1000 kg, or urea is 5 to 7 kg, and the ternary compound fertilizer is 8 to 10 kg water 500 to 700 kg pouring. When the peas grow taller, they will promptly insert the bamboo vines to raise the vines. The spring oysters will raise the roots for high yields and use bamboo vines to take the “people†shape frame with height of 1 to 1.8 meters, and tie 3 to 30 centimeters from the ground. 4 crossbars clamp the branches inside and out to prevent lodging and facilitate day-to-day management.
2 Appropriate application of fertilizer. During the initial flowering period, 1000-1500 kg of cleansing water is applied per acre, or 5 to 7.5 kg of urea, 15 to 20 kg of ternary compound fertilizer, and 300 to 500 kg of water are applied. At the same time, 0.5% borax or 0.02% is used. 0.05% of ammonium molybdate solution, or 150g of potassium dihydrogen phosphate, 0.25kg of urea and 60-80kg of water; during the seedling stage, 4-5kg of urea per mu, and 5-7kg of water of ternary compound fertilizer Pouring, and using potassium dihydrogen phosphate 100 grams plus 50 grams of borax 50 grams of water 50 kg spray 2 to 3 times, each with a liquid volume of 50 to 75 kg, sprayed every l0 ~ 15 days. Generally 8 to 12 days after flowering, soybean meal can be seen in the light of the grain, when the color turns deep, it begins to pick. After every 7 to 10 days, it is harvested once and topdressed once. Top dressing can be applied to 20% to 30% of manure. Urine 800 to 1000 kg. If there is no rain and drought for a long time, 0.5% urea water can be used for pouring, which can both add nutrients and resist drought.
