preparation example Construction

[0054] The preparation method of pecan cattail shell fermentation powder is:

[0055] 1) Collect hickory cattail shells during the hickory harvest season;

[0056] 2) Screw extrusion to remove part of the moisture;

[0057] 3) Put the hickory cattail shell into the horizontal fermentation equipment for fermentation, the fermentation temperature is 55-60°C, and the fermentation time is 10-15 days (no large amount of gas is produced, and the fermentation can be judged to be completed when the fermented product has a rotten smell); Good hickory cattail shells are broken, sieved, and dried to obtain hickory cattail shell fermentation powder;

[0058] The obtained hickory cattail shell fermented powder has an organic matter content of more than 60 percent, a water content of less than 25 percent, and a 20-mesh passing rate of more than or equal to 90 percent.

[0059] The preparation method of the special organic slow-release fertilizer for cereal crops is as follows: mixing each...

Abstract

The invention discloses organic slow-release fertilizer special for cereal crops and application of the organic slow-release fertilizer. The organic slow-release fertilizer comprises an inorganic component and an organic component, wherein the weight percentage of the organic component is 25-40%; the N element content in the inorganic component is 10-15% by using the weight of the organic slow-release fertilizer as reference, P element content is 4-7% by the weight of P2O5, and K element content is 6-12% by the weight of K2O; the organic component comprises, by weight, 5-10 parts of lignin, 5-10 parts of biomass charcoal, 5-10 parts of potassium fulvate and 5-10 parts of Carya cathayensis Sarg peel powder. The organic slow-release fertilizer has the advantages that the organic component which comprises the lignin, the biomass charcoal, the potassium fulvate and the Carya cathayensis Sarg peel fermentation powder is added into fertilizer to prepare the slow-release fertilizer special for the cereal crops, the slow-release fertilizer is good in slow release performance, high in fertilizer utilization rate, low in energy consumption and environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of fertilizer application, in particular to a special organic slow-release fertilizer for cereal crops and its application. Background technique [0002] China is a big agricultural country, as well as a big producer and consumer of chemical fertilizers. China's total output and consumption of chemical fertilizers rank first in the world. However, the practice of agricultural production shows that due to the comprehensive influence of fertilizer properties and soil environmental conditions, low fertilizer use efficiency is a common problem in the process of using chemical fertilizers. At present, the utilization rates of nitrogen, phosphorus and potassium fertilizers of the three major staple crops are about 33%, 24% and 42% (the Ministry of Agriculture's "Action Plan for Zero Growth in Fertilizer Use by 2020"), and the low fertilizer utilization rate has produced a series of negative effects on the environm...
