In recent years, some rice production areas have improved traditional methods of rice cultivation and have achieved good results. The main results are as follows: I. Prevention and control of diseases and pests Putting Daejeon medicines into cultivation before the cultivation of Putian concentrates can be used to reduce the risk of disease. effect. The method is to use carbendazim and other fungicides and insecticides to mix the water on the day prior to the transplanting and transplanting, and to conduct comprehensive spraying on the fields of Putian to prevent and reduce the occurrence of field diseases and insect pests. Second, double planting is generally considered that hybrid rice has strong tillering ability, and most of them are planted with individual plants, which results in insufficient number of basic seedlings in Daejeon, and it is difficult to increase yield. Transplanting two plants with pods not only greatly improved the effective panicle but also the long panicle and high seed setting rate. Therefore, planting double plants is an effective way to increase yields. 3. Transplanting Daejeon at time of transplanting When transplanting in field, you should try to avoid the hot weather in the hot sun, choose rainy weather or sunny afternoon or late afternoon transplanting. It can avoid the burning of the seedlings, making them return green, hair roots early, and more tillers to lay the foundation for increasing the yield. IV. Topdressing After promoting field transplanting, Jishi applied forced manure, panicle-fertilizer and strong grain fertilizer on time. One-time application of all topdressing fertilizers to base fertilizers and then transplanting them into the field will allow the seedlings to grow fertilizers early and return to green, increase effective tillers, and increase disease resistance. The specific method of operation is that in the last cultivation of Daejeon, 50 kg of compound fertilizer, 25 kg of phosphate fertilizer, and 20 kg of urea were used for 667 square meters, applied to the field at one time, and then mixed and cultivated. V. Farmland fertilization Most peasant households increase investment in their own share of the plot year by year in order to return yields. Some paddy fields have a large amount of circulatory fertilizer or green manure for a long period of time, which makes the soil fertile and nitrogen fertilizers abundant, but phosphorus and potassium fertilizers are insufficient. At the time of harvest, the rice straw is vigorous but there are more rice grains in the panicle. Therefore, as long as the adjustment of single fertilizer type over the years, increase phosphorus, potassium fertilizer, you can change the "fat field low-yield" phenomenon to ensure high yield and stable rice production.
