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): 35 shrimp bran, 6 calcium lactate, 50 dried cow dung, 22 oil feet, 5 sodium iron edetate, 4 potassium sulfate, 3 sodium phosphate, fresh enteromorpha 150, compound microbial agent 4, wheat straw 230, fresh urine 25, 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 shrimp bran, dried cow dung, and oil feet, 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 Stir the fermented material evenly to star...

Abstract

The invention discloses a wheat straw biochar fertilizer for improving a root absorption capability and a preparation method thereof. The biochar fertilizer is prepared by from the following raw materials in part by weight: 34-36 parts of shrimp bran, 5-7 parts of calcium lactate, 45-55 parts of dried cow dung, 20-24 parts of oil sediment, 4-6 parts of EDTA ferric sodium salt, 4-5 parts of potassium sulfate, 3-4 parts of sodium phosphate, 140-160 parts of fresh dnteromorpha, 4-5 parts of composite microbial agent, 225-235 parts of wheat straw, 24-26 parts of fresh urine and a proper amount of water. The biochar fertilizer employs wheat straw, dnteromorpha and the like as main raw materials, the added shrimp bran and oil sediment are fermented and applied into soil, under the blending effect of water and soil, micromolecules such as ethane or the like and hormone substances are released, which has beneficial influences on root exudates; in addition, under the chelation of EDTA ferric sodium salt, calcium lactate and the like, root growth process is substantially improved, and absorption and utilization capabilities of nutrients are improved.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a wheat straw biochar fertilizer capable of improving the absorption capacity of roots 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 ...
