How to manage Zizania caduciflora for overwintering

After the harvest of Zizania latifolia, Zizania latifolia enters the overwintering period, and the management of the overwintering period is good or bad, which directly affects the yield of Zizania caduciflora next year. Therefore, it is very important to do a good job in the management of Zizania caduciflora overwintering period. Chongxian Town Agricultural Office actively does a good job in overwintering management of Zizania caduciflora, mainly in the following aspects: first, do a good job in water slurry management of Zizania caduciflora overwintering, prevent freezing and keep warm to promote early development. Because in winter, the weather is relatively cold, with frost, ice and snow. If there is no water in the field, after freezing, it will also cause growth delay and tillering delay. Therefore, the water layer of 1.5-2 inches is required to be irrigated during the overwintering period of Zizania caduciflora, and water management can be reduced when the temperature rises in spring. Second, do a good job of cutting the old shell of Zizania caduciflora to promote new hair. Because cutting or not cutting the old leaves of Zizania caduciflora has a great impact on the growth and tillering of next year. If the old leaves are not cut off, the growth will be delayed and the tillers will be reduced next year. Cutting off the height of the old leaves can control the number of new buds of Zizania latifolia. The withered leaves should be treated centrally in order to reduce the number of diseases and insect pests. The third is to apply enough organic fertilizer before the Spring Festival and nitrogen, phosphorus and potassium fertilizer during the germination period of Zizania caduciflora.
