preparation example Construction

[0053] The present invention also provides the preparation method of described special fertilizer for rice, comprising the steps of:

[0054] (1) Mix feces, straw and microbial inoculum to obtain fermented material, and accumulate and ferment the fermented material for 26-30 days to obtain decomposed organic material;

[0055] (2) Mix the decomposed organic material with urea, dicalcium hydrogen phosphate, diammonium hydrogen phosphate, potassium chloride, potassium fulvic acid, glutamic acid, amino acid chelated zinc and amino acid chelated selenium, and granulate to obtain rice special Fat.

[0056] In the present invention, the accumulation fermentation time is preferably 27-29 days, more preferably 28 days; the water content of the fermentation material during the accumulation fermentation is 61-65%, preferably 62-64%, more preferably 63% ;

[0057] The central temperature of the fermentation heap during the stacking fermentation is 30-60°C, preferably 40-50°C, more pref...

Embodiment 1

[0080] Take 50 kg of cow dung, 30 kg of corn stalks, 30 kg of soybean stalks, 0.2 kg of Bacillus subtilis inoculum, and 1.2 kg of Trichoderma inoculum, and mix them evenly to obtain a fermentation material. Stack and ferment the fermented material at a water content of 61%, and keep the central temperature of the fermentation pile between 30 and 60°C. When the central temperature of the fermentation pile is greater than 60°C, turn the pile immediately. When the temperature is lower than 30°C, the film shall be kept warm. The fermented material was stacked and fermented for 26 days to obtain decomposed organic material.

[0081] Add 28kg urea, 8kg dicalcium hydrogen phosphate, 10kg diammonium hydrogen phosphate, 12kg potassium chloride, 3kg potassium fulvic acid, 2kg glutamic acid, 1.5kg amino acid chelated zinc, 6kg amino acid chelated selenium in the decomposed organic material, Mix evenly, add to a granulator, and granulate to obtain special fertilizer for rice.

Embodiment 2

[0086] Take 56kg of chicken manure, 58kg of soybean stalks, 0.25kg of Bacillus subtilis inoculum, and 1.75kg of Trichoderma inoculum, and mix them evenly to obtain the fermentation material. Stack and ferment the fermented material at a water content of 62%, and keep the center temperature of the fermentation pile between 30 and 60°C. When the center temperature of the fermentation pile is higher than 60°C, turn the pile immediately. When the temperature is lower than 30°C, the film shall be kept warm. The fermented material was stacked and fermented for 30 days to obtain decomposed organic material.

[0087] Add 30kg urea, 10kg dicalcium hydrogen phosphate, 9kg diammonium hydrogen phosphate, 10kg potassium chloride, 6kg potassium fulvic acid, 1kg glutamic acid, 2kg amino acid chelated zinc, 5kg amino acid chelated selenium to the decomposed organic material, mix Evenly, add to the granulator and granulate to obtain special fertilizer for rice.

[0088] 6 days before rice tr...

Abstract

The invention provides a special fertilizer for rice and a preparation method and application thereof, and relates to the technical field of fertilizers. The special fertilizer for rice comprises the following components in parts by mass: 50-60 parts of excrement, 50-60 parts of straws, 1-3 parts of a microbial agent, 26-30 parts of urea, 8-10 parts of dicalcium phosphate, 8-10 parts of diammonium hydrogen phosphate, 10-14 parts of potassium chloride, 3-6 parts of potassium fulvate, 1-2 parts of glutamic acid, 1-2 parts of zinc amino acid chelate and 3-6 parts of selenium amino acid chelate. When the fertilizer is used for planting the rice, the yield of the rice can be increased, the protein content, the selenium content and the calcium content in the rice can be increased, and the quality of the rice is improved.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a special fertilizer for rice and its preparation method and application. Background technique [0002] Rice is one of the most important food crops for human beings. Half of the world's population uses rice as a staple food, so the cultivation of rice is particularly important. Fertilizer is the food of crops, which can provide nutrients for the growth of crops. However, in order for crops to grow rapidly and grow robustly, they need to rely on good fertilizers and reasonable fertilization. If the combination of fertilizers is unreasonable and improper fertilization is like an unbalanced diet, it will lead to unhealthy body, weakened resistance to germs, and easy to get sick. There is still the problem of irrational application of fertilizers when the prior art is used for rice planting. Therefore be badly in need of a kind of compound application rationally, not only can...
