Problems solved by technology

[0004] However, due to the light weight of biochar, it is in the form of powder, takes up a lot of space, and the cost of transportation and storage is high. In addition, there are difficulties such as inconvenient application and dust pollution in the process of farmland application, which limits the agricultural promotion and utilization of biochar.

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] Take the raw material of following parts by weight (kg) and make: furfural slag 22, oligomeric chitosan 4, sargassum powder 48, sodium silicate 4, peat soil 14, calcium sulfate 2, potassium iodide 4, fresh enteromorpha 105, Composite microbial agent 7, wheat straw 200, fresh urine 26, 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, mash it, mix it with sargassum powder, furfural residue, and peat soil, put it into the fermentation tank, add water to adjust the water content to 50-60%, and then inoculate the compound microbial agent into the fermented product, and then S...

Abstract

The present invention discloses a wheat straw biochar fertilizer for regulating root system nutrients, and a preparation method thereof, wherein the wheat straw biochar fertilizer is prepared from the following raw materials by weight: 20-24 parts of furfural residue, 3-6 parts of oligomerization chitosan, 45-50 parts of scagassum powder, 3-5 parts of sodium silicate, 13-15 parts of peat soil, 1-3 parts of calcium sulfate, 4-5 parts of potassium iodide, 95-115 parts of fresh enteromorpha, 6-7 parts of a composite microbial agent, 190-210 parts of wheat straw, 24-28 parts of fresh urine, and a proper amount of water. With the wheat straw biochar fertilizer of the present invention, the crop growth is ensured, the waste of the fertilizer efficiency due to the application of the fertilizer application to improve the nutrient level of the whole cultivating layer of the soil is avoided, the production cost is reduced, and the economic benefited are improved.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a wheat straw biochar fertilizer for regulating root system nutrients 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 of agr...
