Embodiment

[0028] A method for cultivating rice, comprising the steps of:

[0029] 1) Work before transplanting

[0030] Paddy fields should be plowed early and deep, and the ground should be finely raked. The ridge height of paddy fields should be 30cm;

[0031] For disease prevention, select varieties with strong disease resistance, apply well-decomposed manure, and use fermented organic fertilizers to improve the soil, wherein the components of the organic fertilizers are N / C ratios of 20 to 30, and the water content of the organic fertilizers during fermentation It is 40-50%, keep air circulation in the fermentation heap, and the fermentation temperature does not exceed 70°C;

[0032] 2) Rice transplanting

[0033] Transplant seedlings at the right time; at the beginning, use 30cm row spacing × 20cm hole spacing to transplant seedlings, and insert the pot to the surface of the field; water immediately after transplanting;

[0034] 3) Water management

[0035] Maintain a water lay...

Abstract

The invention discloses a method for cultivating rice. The method comprises the following steps: ploughing a paddy field, improving the soil with fermented organic fertilizer, transplanting rice seedlings, managing with water, using rice chaff, corn straw powder, leaf powder, beanstalks, crushed corn and pyroligneous acid for killing weeds and insects, harvesting rice and the like. After the proper organic fertilizer is put into the soil, the fertile soil with high organic matter content, few weeds and no pollutants is obtained and suitable for organic cultivation of rice, and the improvement time is short; and as rice chaff, corn straw powder, leaf powder, beanstalks, crushed corn and pyroligneous acid are used for killing weeds and insects, the weeding cost is low, the weeding effect is complete (more than 90 percent), no pesticide residue is left, and the final quality of rice is ensured.

Description

technical field [0001] The invention relates to the field of rice cultivation, in particular to a method for rice cultivation. Background technique [0002] In the existing rice cultivation, various chemical herbicides are usually used for weeding. The cost of weeding is high but the weeding is not thorough, and pesticides are generally used to prevent pests and diseases, which will cause pesticide residues, etc., which will damage the quality of the final rice and damage the soil. Big. Paddy improvement is the most basic condition in organic rice production. Only with good soil can high yield and rice quality be improved. The soil conditions suitable for organic rice cultivation are high in organic matter, fertile, with few weeds and no pollutants. It will take at least 4-5 years to improve and fertilize this soil, and it will take a lot of effort. Contents of the invention [0003] The technical problems to be solved by the present invention are low soil quality, hig...
