Embodiment Construction

[0020] specific implementation plan

[0021] The present invention will be described in further detail below in conjunction with the following specific embodiments:

[0022] Weigh the following raw materials in parts by weight (kg): silkworm excrement 50, copper fulvic acid 7, monocalcium phosphate 4, chestnut shell powder 17, potassium pyrophosphate 4, hops 24, ammonium bicarbonate 10, fresh enteromorpha 165 , Composite microbial agent 6, wheat straw 225, fresh urine 28, appropriate amount of water;

[0023] The composite microbial bacterial agent includes Rhizopus oryzae, Bacillus subtilis and Bacillus cereus in a ratio of 1:2:2.

[0024] The concrete steps of the preparation of described fertilizer are as follows:

[0025] (1) Wash the Enteromorpha enteromorpha, mash it, mix it with hops, silkworm excrement, and chestnut shell powder, put it into the fermentation tank, add water to adjust the water content to 45-55%, and then inoculate the complex microbial agent into the...

Abstract

The invention discloses a wheat straw biocarbon fertilizer capable of reducing the harms of pesticide residues and a preparation method thereof. The fertilizer is composed of the following raw materials in parts by weight: 48 to 52 parts of silkworm excrement, 6 to 8 parts of copper fulvate, 3 to 5 parts of monocalcium phosphate, 16 to 18 parts of chestnut shell powder, 4 to 5 parts of potassium pyrophosphate, 22 to 26 parts of hop, 8 to 12 parts of ammonium bicarbonate, 160 to 170 parts of fresh enteromorpha, 5 to 7 parts of composite microbial inoculant, 220 to 230 parts of wheat straw, 27 to 30 parts of fresh urine, and a proper amount of water. In the skeleton of straw biocarbon, fermenting substance such as silkworm excrement, enteromorpha, and the like, are added, the nutrients of the fertilizer particles are enriched; at the same time, the added copper fulvate and potassium pyrophosphate contains a great amount of functional groups, so the performance on absorbing the polycyclic aromatic hydrocarbon in the soil is enhanced, thus the bio-availability of organic pollutants such as residual herbicide, residual pesticide, and the like is reduced, the absorption of the organic pollutants by the crops is reduced, and the normal growth of crops is guaranteed.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a wheat straw biochar fertilizer for reducing the harm of pesticide residues and a preparation method thereof. Background technique [0002] Biochar is an organic substance rich in stable carbon obtained by oxygen-limited pyrolysis and carbonization of biomass. Biochar can not only effectively increase the organic carbon content in the soil, but also gradually improve soil fertility and water retention. Soil nutrient loss and other aspects also have good effects. [0003] As the proportion of my country's agricultural products exports continues to increase, agriculture's requirements for fertilizers and soil fertility will continue to upgrade. Therefore, the use of biochar fertilizers from the perspective of changes in the types of soil fertilizers and fertility improvements will have a significant impact on the adjustment of my country's agricultural structure and the export...
