[0050] Example 2 Nanjing Liuhe Production Area

[0051] The production method of biological fertilizer is as follows:

[0052] (1) by weight, pig manure 200kg, silkworm manure 100kg, human excrement 50kg, soybean cake 50kg are dropped into fermentation tank, add water 100kg, cover and ferment for 40 days, to a little odor;

[0053] (2) add 800kg of water, continue to ferment for 20 days, to dissolve the solid components in the ingredients;

[0054] (3) get 200 meshes of fermented liquid and filter, get selenium-enriched fertilizer mother liquor;

[0055] (4) Biological fertilizer: add 35kg of zinc sulfate, 40kg of ferrous sulfate, and 0.5kg of sodium selenite to 100kg of mother liquor to dissolve and stir evenly without precipitation. After the reaction is complete, the zinc-rich fertilizer can be filled. The zinc element concentration of the stock solution is 80g / L, the iron element is 80g / L, and the selenium element is 2.2g / L.

Abstract

The invention relates to a preparation method for a zinc-iron-selenium-rich biological fertilizer and a usage, which belongs to the technical field of crop production. Water is added into pig manure, silkworm excrement, human excrement and colza cakes for a fermentation to get mother liquor of the biological fertilizer; zinc sulfate, green copperas, sodium selenite are added into the mother liquor for reactions to get zinc-iron-selenium-rich biological foliar fertilizer for the rice. The fertilizer is separately sprayed in the booting stage and the full heading stage of the rice, with an amount of 1000ml per mu. The function rice, with zinc content 19.4 to 28.7mg / kg, iron content 7.0 to 20.2mg / kg, and selenium content 0.08 to 0.15 mg / kg, measures up to the limit standards of zinc, iron, and selenium in the national food standards. Organic selenium accounts for more than 99% of the total selenium in the zinc-iron-selenium-rich function nutritive rice. The preparation method for the zinc-iron-selenium-rich biological fertilizer proves effective, economical, safe and non-polluted through twice foliage sprays with zinc-iron-selenium fertilizer for the rice as an experiment.

Description

1. Technical field [0001] The preparation method of the zinc-iron-selenium-enriched biological fertilizer and the method for optimizing the production of functional rice of the present invention belong to the technical field of crop production, and are specially used for the optimized production of zinc-iron-selenium functional rice. 2. Technical background [0002] For a long time, my country's rice production has mainly focused on yield and neglected quality. With the development of reform and opening up and the development of socialist modernization, people's living standards are improving day by day, and people's dietary structure has changed significantly. People have higher and higher requirements for the variety and quality of rice, in addition to the requirements for safe consumption, high quality, and functions such as health care nutrition and medicated diet. Modern nutritional studies have shown that trace active elements such as iron, zinc, selenium, copper, and ...
