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] Weigh the following raw materials in parts by weight (kg): coffee grounds 35, cassava grounds 42, potassium monohydrogen phosphate 19, ferrous sulfate 5, calcium nitrate 6, attapulgite powder 15, coconut milk 14, fresh enteromorpha 130, Composite microbial agent 7, wheat straw 240, fresh urine 30, 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 and mix it with coffee grounds, cassava residue, and attapulgite powder, put it into the fermentation tank and add water to adjust the water content to 50-60%, and then inoculate the compound microbial agent into the ferme...

Abstract

The invention discloses a lodging resistant wheat straw biochar fertilizer and a preparation method thereof. The biochar fertilizer is prepared from the following materials by weight: 30-40 parts of coffee residues, 40-45 parts of cassava residues, 18-20 parts of dipotassium hydrogen phosphate, 4-6 parts of ferrous sulphate, 5-7 parts of calcium nitrate, 14-16 parts of attapulgite powder, 12-15 parts of coconut milk, 120-140 parts of fresh enteromorpha, 6-8 parts of composite microbial agent, 230-250 parts of wheat straw, 28-32 parts of fresh urine, and a proper amount of water. Biochar fertilizer particles provided by the invention are light and porous, after the fertilizer is applied in soil, soil physical properties are directly influenced, soil unit weight is lowered and aeration pores are increased and a good growth space is provided for a root system. Biologically-active substances in the added coconut milk can promote deep growth and stretching of the root system. Sufficient element supplements can be provided for the root system in cooperation with ferrous sulphate and calcium nitrate, and the lodging resistant capability of crops is raised.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a lodging-resistant wheat straw biochar fertilizer 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 agricultural products....
