Abstract

A selenium-rich slow-release organic fertilizer used for paddy rice planting is provided. The selenium-rich slow-release organic fertilizer comprises urea, poultry manure, corn straw, bagasse, rapeseed cakes, EM bacterial strains, ribavirin, triazolone, sodium selenite, a slow release agent, EDTA chelated iron, EDTA chelated zinc, EDTA chelated copper, amino acid chelated manganese, amino acid chelated iron, amino acid chelated molybdenum, a urease inhibitor and a nitrification inhibitor. The selenium-rich slow-release organic fertilizer organically combines the urea and an organic fertilizer, and comprises a plurality of trace elements and a sterilization and disease preventing additive. Inorganic and organic fertilizers are combined. Soil of a paddy rice field is protected, and the content of nutrients in the soil is increased. Microorganism strains and a sterilizing agent are combined in the selenium-rich slow-release organic fertilizer, thus boosting disease resistance of the paddy rice field. The production cost is low so that market popularization is facilitated and economic benefit is good.

Description

technical field [0001] The invention relates to a selenium-rich slow-release organic fertilizer for rice planting and a preparation method thereof. Background technique [0002] Rice (scientific name: Oryza sativa) is a kind of herbaceous Oryza sativa, and it is also the most important and longest food in Oryza genus. It is also called Asian cultivated rice, and it can be said to be rice in simple terms. It is an annual, gramineous plant, monocotyledonous, sexually warm and humid, about 1 meter high when mature, with slender leaves, about 50 to 100 cm long and 2 to 2.5 cm wide. The flowers of rice are very small. When blooming, the main flowering branches will be arched, and small flowers will bloom between 30 and 50 cm below the branches. Most of them are self-pollinating and set seeds, which are called rice spikes. Generally, the size of the rice ear is 5 to 12 mm long and 2 to 3 mm thick. [0003] About half of the world's people eat rice as a staple food, especially in...
