Ziyunying, also known as safflower, is a major green manure planted in southern China. After the sowing, the temperature in the early stage was high, and it entered the cold and cold weather in January this year , which was extremely unfavorable for the growth of Chinese milk vetch. Therefore, it is necessary to do a good job in field management, promote the rapid development of spring, and increase the yield of fresh grass.
Â
First, prevent waterlogging. Ziyunying has the characteristics of moistening, not only drought, but also afraid of waterlogging, so the whole growth period must be managed with water to ensure that the soil has a certain humidity. In the winter and spring when there is a lot of rain, we must do a good job of clearing the ditch and clearing the ditch, dredge the ditches, the ditches and the gutters in the field of Ziyun Ying, and remove the stagnant water and waterlogging in time.
Â
Second, anti-fertilization. Chinese milk vetch is a legume green manure, which is particularly sensitive to phosphate fertilizer. Phosphorus deficiency can affect the yield of fresh grass and is also unfavorable for the growth of later crops. Therefore, for the field where the phosphate fertilizer has not been applied in the early stage, it is necessary to supplement the phosphate fertilizer by 20~25 kg, and the per kilogram of superphosphate can increase the yield of fresh grass by 40-50 kg. After the spring, for the field with poor seedlings, some quick-acting nitrogen fertilizers can be applied as appropriate. 4~5 kg of urea per acre or 15~25 kg of ammonium bicarbonate can be used. Generally, more than 500 kg of fresh grass can be collected . For the cultivation of Chinese milk vetch, 0.1%~0.2% potassium dihydrogen phosphate solution can be sprayed to increase the seed production.
Â
Third, anti-drying. Timely selection of sunny days with little rain and temperature rise, properly pouring some horse water to prevent dry freezing hazards.
Â
Fourth, prevent pests and diseases. The diseases of Chinese milk vetch are mainly Sclerotinia sclerotiorum, powdery mildew, round spot disease and leaf blight. When the sclerotia is found in the growing period, the diseased plant should be removed and burned, and the lime is scattered in the disease center. Powdery mildew and round spots Disease, spray with 0.4 degree stone sulphur mixture, can also be applied with 1 : 5 sulphur lime powder. Milk vetch pests are aphids, thrips, leaf miner, are generally green manure prevention field one time, stay in farming prevention 3 to 4 times, each Mu can use leaf hopper powder 0.4~0.5 kg mixed grass ash 8~10 kg, spray in the morning when the dew is not dry, or use 40% dimethoate emulsion, or 50% malathion 200 g spray 45~50 kg water Prevention and treatment. In the rainy days, we must also pay close attention to the prevention and control of spraying without rain, especially to spray the seeds to keep the seeds in order to increase seed yield.Stainless Steel Bathroom Accessories
