The commonly used green manure is Ziyunying and Safflower, which are legume green manure crops. According to their growth habits and nutritional characteristics, it is an important measure to capture the high yield of green manure after sowing. Open a good "three ditch." As the saying goes: "Green manure ditch, stable production and stable income." Due to the early fear of drought and late drought, the green manure should be expanded in time after the harvest of the double-season rice to deepen the old ditch, so that the "three channels" (main channel, Weigou, Xianggou) can be matched. Generally every 2 meters to open a car ditch, the ditch depth of 0.2 meters, the main ditch, ditch to break the plow bottom, so that the ditch connected, can irrigation can row. Increase winter hair root fertilizer. Apply 25 to 30 kg of calcium phosphate per mu. For phosphorus-free land, apply 10 to 20 kg of potassium chloride or 10 to 20 tons of plant ash. Generally, early application is better than late application, and it must be applied before the Spring Festival at the latest. In this way, the root development of the green manure, the nitrogen-fixing activity of the rhizobia, the phosphorus nitrogen increase, the seedling maintenance in winter, early winter and strong growth, etc. all have significant effects. According to local trials, the application of P and K fertilizers increased 50 to 100% compared with the control. After the spring to promote fat. To achieve early Qing "three ditch." There is much rain in spring, and in order to create a good dry and wet soil condition for the green manure, it is necessary to timely clear the gutter drainage in the early spring so that the rain will stay dry. Simultaneous application of grass fat. After the spring begins, the growth rate of green manure is accelerating, and the demand for nutrients increases. Therefore, it is necessary to look at the fields and see the seedlings. The seedlings can quickly raise seedlings to promote spring growth, and the general Mushi urea is 3 to 5 kilograms. The purpose of using inorganic fertilizers for organic fertilizers. Timely prevention of pests and diseases. The diseases of green manure mainly include sclerotinia and powdery mildew; insect pests mainly include thrips, aphids, leafminers, and tigers. For sclerotinia and powdery mildew, 70% thiophanate-methyl wettable powder 1000 to 1500 can be used. Diluent or 50% carbendazim WP 1500 to 2000 times spray; for thrips, aphids, leaf miners, 15% imidacloprid wettable powder 2000 times or 2.5% emulsion liquid 1500 times or 5 % Suppository EC can be sprayed with 1000 to 2000 times spray; the ground tiger can be captured manually or by bait trapping. Green manure is a green plant used as a fertilizer. Green manure is a complete source of bio-fertilizer. Green manure is not only an effective way to increase the source of fertilizer, but also has a great effect on soil improvement. Green manure crops are rich in organic matter and contain nutrients such as nitrogen, phosphorus, potassium, and various trace elements. It is rapidly degraded and has a rapid fertilizer effect. Generally, green manure containing 1 kg of nitrogen can increase rice production and wheat production by 9 to 10 kg. Because green manure contains a large amount of organic matter, it can improve the soil structure, improve the soil's ability to retain water and fertility, and provide fertilizer. The green manure has lush stems and leaves covering the ground, which can prevent or reduce the loss of water, soil, and fertilizer.
