Rice fertilizing method

Abstract

The invention discloses a rice fertilizing method. The rice fertilizing method comprises the following steps: (1) fertilizing during soil preparation, namely, during soil preparation before rice seedling transplanting, fertilizing at a time, wherein the fertilizing amount is 30-35kg / mu, and the applied fertilizer is a mixed fertilizer prepared from an organic fertilizer and an inorganic fertilizer at the weight ratio of 8 to 2; (2) fertilizing during the tillering stage, namely, applying nitrogen fertilizer in the amount of 6-7kg / mu 3-5 days after rice seedling transplanting, and applying nitrogen fertilizer in the amount of 3-4kg / mu and potash fertilizer in the amount of 6-7kg / mu 6-7 days later; and (3) fertilizing during the heading period, namely, applying a mixed fertilizer prepared from an organic fertilizer and an inorganic fertilizer at the weight ratio of 2 to 3 when the heading ratio reaches 75%, wherein the applying amount is 3-5kg / mu, and then applying nitrogen fertilizer in the amount of 3-4kg / mu and potash fertilizer in the amount of 2-3kg / mu when the heading ratio is above 90%. During the fertilizing process, the organic fertilizer and the inorganic fertilizer are combined, the application amount of the organic fertilizer is increased, the operation is simple and effective with little pollution, and the yield of the rice can be well improved.

Description

technical field [0001] The invention relates to a rice fertilization method, which belongs to the technical field of crop planting. Background technique [0002] Rice is one of the main food crops in my country, and the output of rice is related to the national economy of our country. In the process of rice planting, the quality of fertilization is closely related to the yield of rice. With the growth of our population, the reduction of cultivated land, the small scale of production, the shortage of water resources, the threat of drought, and the promotion of returning farmland to forests, etc., a series of problems have objectively aggravated the contradiction of food demand, and the promotion of agricultural technology is not in place. At present, there are still various hidden dangers and risks in my country's food problem that cannot be underestimated.

Problems solved by technology

With the growth of our population, the reduction of cultivated land, the small scale of production, the shortage of water resources, the threat of drought, and the promotion of returning farmland to forests, etc., a series of problems have objectively aggravated the contradiction of food demand, and the promotion of agricultural technology is not in place. At present, there are still various hidden dangers and risks in my country's food problem that cannot be underestimated.

[0003] At present, relatively single chemical fertilizers are usually used in the rice planting process, and in order to increase the yield, the amount of fertilizer is usually increased blindly. Although excessive fertilization will increase the yield of rice to a certain extent, it also brings serious damage to the land. The burden will also lead to land salinization, and also increase the cost of planting to a certain extent
