Changing the traditional rice planting method is

For rice, there are many planting modes, but in general, there are two kinds: transplanting and direct seeding. Therefore, whether for transplanting or direct seeding field, direct seeding transplanting is basically idle field and wheat stubble rotation. Before planting rice, the soil in the paddy field must be ploughed to make it soft. This process is divided into three periods: rough tillage, fine tillage and leveling. In the past, animals and plows, mainly buffaloes, were used for soil preparation and ploughing, but now machines are used for soil preparation.

Double cropping rice production should be resumed. In recent years, the area of rice in one season has increased a lot for many reasons. However, the yield per mu of season rice is 500 ~ 600 Jin, which is 300 ~400 Jin lower than that of double-season rice, and the loss is great. The green, high-quality and efficient cultivation techniques of rice have strict technical requirements because of the influence of variety characteristics and other factors. Sowing date, density, weeding, fertilization, pesticide use and field water management will all affect the quality of rice products.

Raising seedlings is the first important link of rice cultivation and the basic work of high yield. Its purpose is to cultivate strong seedlings, achieve high seedling rate, neat seedlings and Miao Zhuang, and ensure that enough seedlings are planted in time. After planting, it turns green and survives quickly, tillers early and grows well. According to the target yield, variety characteristics and soil fertilizer supply capacity, the reasonable fertilizer dosage is determined. Hybrid rice has developed root system and strong fertilizer absorption ability, and the fertilizer application amount can be reduced compared with conventional varieties.

Paddy field is planted year after year, which not only absorbs a lot of trace elements such as nitrogen, phosphorus and potassium from the soil every year, so inorganic fertilizer alone can not meet the needs of rice production, and organic fertilizer and inorganic fertilizer must be applied together. When rice seedlings enter the turning green period, they should be watered once in time, but not too much water. A small amount of water can promote tillering. Attention should be paid to controlling the number of tillers to prevent too many ineffective tillers, consuming too much nutrition and affecting rice growth. In order to ensure the uniformity of sowing, the method of quantitative, dilute first and then supplement can be adopted, that is, 80% of seeds are sown first, and then 20% of seeds are used to supplement the deficiency and dilute.
