Cultivating method for direct sowing rice

Abstract

The invention provides a cultivating method for direct sowing rice. The cultivating method includes the steps that a rice field is treated and flattened, base fertilizer and a synergist are applied, and then sowing and irrigating are carried out, wherein the amount of the base fertilizer applied to each mu of the rice field is 50 kg, and the amount of the synergist applied to each mu of the rice field is 6 kg; 18-22 days after irrigating, 10 kg of urea powder with the nitrogen content being 46% is applied to each mu of the rice field; 28-32 days after irrigating, a first additive is applied to the rice field; 48-52 days after irrigating, a third additive is applied to the rice field; 73-77 days after irrigating, a second additive and the third additive are sequentially added to the rice field; 7 days after the former step is completed, the second additive is applied to the rice field again; 83-87 days after irrigating, the third additive is applied to the rice field; 93-97 days after irrigating, the third additive is applied to the rice field again. By means of the method, the growth period of traditional direct sowing rice can be shortened, diseases can be effectively resisted, and the yield per mu can be effectively increased.

Description

technical field [0001] The invention relates to the field of rice planting, in particular to a cultivation method for direct-seeding rice. Background technique [0002] Direct-seeding rice technology is a cultivation mode developed in recent years, but the growth period of existing rice varieties is relatively long. In the past, most of the cultivated rice along the Huaihe River was harvested before October 25. After switching to direct-seeding rice, the harvest period of rice was delayed by nearly 20 days, and wheat could only be sown in mid-November. The direct seeding of rice prevents the wheat from being sown at the optimum sowing time, resulting in a reduction in wheat production and the inability to survive the winter safely. The existing technical scheme is to change the growth period of rice, and it takes 8-10 years to cultivate varieties with a short growth period from cultivation to mass production, which seriously affects the development of agriculture. In the p...

The demand for urea in the cultivation of rice in the prior art is very high. Generally, it needs to be used three times at (tillering stage, jointing stage, and booting stage), and it is impossible to add urea in the later stage.
