What kind of new model of rice planting that can make higher returns?

For rice, there are many modes of planting, but the general situation is transplanting and direct seeding two kinds of, then whether for transplanting field or direct seeding field, basically is the idle field and stubble rotation direct seeding, transplanting, before planting rice, you must first turn over the paddy field soil to make it fluffy, the process is divided into rough plowing, fine plowing and cover the leveling of the three periods. In the past, animal power and plowing tools, mainly buffaloes, were used to prepare the field for plowing, but now more machines are used to prepare the field.

To restore double-season rice production. In recent years, the area of one-season rice has increased quite a lot, which has many reasons; however - the mu yield of one-season rice is 500 ~ 600 kilograms, which is 300 ~ 400 kilograms less than that of two-season rice, which is a major loss. The green high-quality and efficient cultivation technology of rice, because of the influence of the characteristics of varieties and other factors, the technical requirements are strict, sowing period, density, weed control, fertilization, and the use of pesticides, field moisture management, etc., all of which affect the quality of rice products.

The seedling is the first important link in rice cultivation and the foundation work for high yield. It is to cultivate strong seedlings for the purpose of achieving a high rate of rice seedlings, seedling flush, seedling strong, to ensure that there are enough seedlings planted in time. After planting, they will be quick to return to the green and become active, tiller early and grow well. According to the target yield, variety characteristics and soil fertilizer capacity to determine a reasonable amount of fertilizer. Hybrid rice root system is developed, fertilizer absorption capacity is strong, the amount of fertilizer can be reduced than conventional varieties.

Rice planted in successive years, each year not only to be absorbed from the soil away from a large number of N, P, K and other trace elements, therefore, relying only on inorganic fertilizer supplementation can not meet the needs of rice production, the implementation of organic fertilizers and inorganic fertilizers must be applied in conjunction. In the rice seedlings into the green period of time to pour a timely green water, but the water should not be too much, small water to promote tillering. Be careful to control the number of tillers to prevent too many ineffective tillers, consuming too much nutrition, affecting the growth of rice. In order to ensure the uniformity of sowing, you can use the method of fixed border quantitative, first thin after filling, that is, 80% of the seeds sown first, and then 20% of the seeds to make up for the lack of fill thin.
