Rice fertilizing method for producing selenium-rich rice

Abstract

The invention provides a rice fertilizing method for producing selenium-rich rice. The rice fertilizing method comprises the steps that a seedling raising plot is selected; seeds are selected; nutrient soil preparation and sowing are performed; soil preparation and mixed fertilizer application are performed; field steeping and topdressing are performed. A mixed fertilizer is prepared from, by weight, 12-15 parts of urea, 16-18 parts of diammonium phosphate, 8-12 parts of potassium chloride, 7-16 parts of amino acid, 5-8 parts of sodium silicate, 11-14 parts of nitrogen phosphorus and potassium fertilizer and 17-40 parts of fermented organic matter. Compared with the prior art, the rice fertilizing method has the advantages that the dose-simplified efficient rice fertilizing method is provided based on a rice fertilizer requirement law and fertilizer absorption characteristics and combining with local climatic characteristics, soil characteristics and a rice nutrient demand law. The method is simple and effective and saves labor, and manpower and financial resource waste caused by topdressing is avoided. The rice fertilizing method is good in fertilizing effect, and the production cost is reduced.

Description

technical field [0001] The invention relates to a rice fertilization method for producing selenium-enriched rice, and relates to the technical field of fertilization. Background technique [0002] Rice is one of the most important food crops in the world, and about 1 / 2 of the population uses rice as a staple food. At present, about 9 million mu of rice is planted in Liaoning Province. As a staple food, rice plays a pivotal role in ensuring my country's food security and improving the nutritional structure of residents. Scientific and reasonable fertilization technology is an important part of high-yield and efficient cultivation and management technology of rice. At present, there are still many problems in the fertilization technology in the rice production process in our province, such as the inability to achieve a reasonable and balanced fertilization, the lack of reasonable scientific and technological guidance for precise fertilization and timely fertilization, etc., r...
