Embodiment Construction

[0022] The present invention will be described in detail below in conjunction with examples.

[0023] In the present embodiment, the ratooning rice cultivation method is as follows:

[0024] S1. Select the rice variety Y Liangyou 900 and plant it by transplanting;

[0025] S2. At the full-heading stage of the first-season rice, apply 15 kg of urea per mu of paddy field; mow at the full-heading stage of the first-season rice or within 10 to 25 days after the full-heading stage. silage treatment of rice straw;

[0026] S3, within 2 days after mowing, apply urea 10kg and potassium chloride 8kg per mu of paddy field;

[0027] S4. Harvest when the yellowing rate of rice grains in the regeneration season reaches more than 95%.

[0028] Under the conditions of different cutting periods, the biological yield of ratooning rice in the first season, the crude protein content of the first season plants, and the annual income are shown in Table 1 and Table 2. It can be seen that the tot...

Abstract

The invention relates to a ratooning rice cultivating method. The method comprises the following steps of selecting the rice kind with high first-season biomass, high regeneration capability and relatively high protein content, and performing planting; cutting in a full heading period or in 10-25 days after the full heading period, wherein the height of the stubble after cutting is 10-30cm, and performing forge processing on the straw obtained through cutting; in two days after cutting, applying 5-15kg of urea and 5-10kg of potassium chloride in each mu; and when the grain yellow rate of the ratooning rice exceeds 95%, performing harvesting. According to the method of the invention, through first-season whole-stem cutting and silage, relatively high biomass of the straw and the paddy is obtained, and a new conception is supplied for settling a straw problem and a forge problem. Through comprehensive consideration of factors such as rice kind, cutting time and field management, an economic benefit in rice planting is maximized, and furthermore a forge requirement and a food requirement are satisfied.

Description

technical field [0001] The invention relates to the technical field of rice cultivation, and relates to a method for cultivating ratooned rice, in particular to a method for cultivating ratooned rice for head-feeding and evening food. Background technique [0002] Rice straw as feed has good experience in my country, especially the use of scientific and technological achievements to convert straw into biological feed. Returning the straw to the field as livestock feed not only promotes the development of animal husbandry, but also provides a large amount of high-quality fertilizer for the farmland, increasing the water storage and fertilizer retention capacity of the soil. In my country, especially in the south, the animal husbandry structure is mainly based on pigs and poultry, and the proportion of herbivores such as cattle and sheep is relatively low. Pig and poultry farming needs to consume a lot of grain, and our country has a large population base and a large demand f...
