Nutritional composition for rice as well as preparation method and application method of nutritional composition

Abstract

The invention provides nutritional composition for rice as well as a preparation method and an application method of the nutritional composition, and belongs to the field of fertilizer supply of the rice. The nutritional composition for the rice comprises raw materials in percentage by mass as follows: 1.5%-2.0% of zinc fertilizer, 2.5%-4.5% of calcium metaborate, 8.0%-15.0% of calcination modified potassium feldspar, 3.0%-8.0% of urea sulfate, 1.0%-3.0% of a biomass binder, 1.5%-2.5% of magnesium fertilizer, 0.3%-0.8% of copper fertilizer and the balance of nitrogen phosphorus and potassium main supply fertilizer. According to the preparation method, the raw materials of the nutritional composition for the rice are mixed in percentage by mass. The composition has the advantages of being comprehensive in nutrition, fast to dissolve, lasting in efficiency and the like, unreasonable fertilization can be controlled effectively, rice resistance can be enhanced, soil acidity is improved, and poison of toxic substances can be relieved. According to the application method, the nutritional composition for the rice is scattered to a paddy field to be complexed with soil after preliminary preparation of the paddy field and before fine preparation and cultivation. Soil can be improved effectively, and fertilizer efficiency can be improved and prolonged.

Description

technical field [0001] The invention relates to the field of rice fertilizer supply, and in particular to a rice nutritional composition, a preparation method and an application method thereof. Background technique [0002] Rice is the food crop with the largest planting area in my country, with 600 million mu of annual planting. Among them, southern my country, including Guangdong, Guangxi, Fujian, Hainan, Jiangsu, Shanghai, Zhejiang, Hunan, Hubei and other places, accounts for more than half of China's rice planting area and has been the main rice producing area in China since ancient times. The rice farming in this area is characterized by 2-3 seasons a year. During the rice growing season, the temperature is high and the rainfall is high. It is often attacked by monsoons and typhoons. The soil is mostly red soil to brick red soil. , the soil is mostly acidic to strongly acidic, deficient in nutrients, high in toxic substances such as iron and aluminum nodules, and the d...

AI Technical Summary

Problems solved by technology

[0003] Due to the characteristics of the soil and climate in this area, the rice production in this area has the following problems: high precipitation, large fertilizer loss, low utilization rate, and large waste; large amount of fertilization, many times of fertilization, time-consuming and high cost; heavy metals High activity, direct seeding threatens the safety of rice; unbalanced nutrition, weak stalks, coupled with tropical cyclones such as monsoons and typhoons, lodging is very common, directly threatening rice production

[0004] At present, for rice production in this area, farmers apply fertilizers based on experience. Blind fertilization, excessive fertilization, and unbalanced single partial application of nitrogen fertilizers are very common, often resulting in lack of nutrients, premature aging or vigorous growth, and serious pests and diseases.

At the same time, when the pests and diseases are discovered by the farmers, they will be treated with symptomatic medicines. Even if they are controlled, losses will inevitably occur, and they will seriously pollute the environment.
