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): apple pomace 28, zinc sulfate 2, bagasse 35, potassium nitrate 15, levulinic acid 3, pandan leaf juice 5, plant ash 30, fresh enteromorpha 130, compound microorganism Bacteria agent 5, wheat straw 270, fresh urine 32, 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 apple pomace, bagasse, and plant ash, put it into the fermentation tank, add water to adjust the water content to 50-55%, and then inoculate the compound microbial agent into the fermented product, and then ferment Stir the material evenly to start fer...

The invention discloses wheat straw biochar fertilizer capable of achieving fertilizer supplying for a long time and a preparation method thereof. The wheat straw biochar fertilizer is prepared from, by weight, 25-30 parts of apple residues, 2-3 parts of zinc sulfate, 30-40 parts of bagasse, 14-16 parts of potassium nitrate, 2-3 parts of levulinic acid, 4-6 parts of pandan leaf juice, 25-35 parts of plant ash, 120-140 parts of fresh enteromorpha, 5-6 parts of compound microorganism bacterium agents, 260-280 parts of wheat straw, 30-34 parts of fresh urine and an appropriate amount of water. According to the wheat straw biochar fertilizer, by adding the enteromorpha, the bagasse and other raw materials, the content of organic humus in soil is greatly increased, and the adsorption and controlled release effect of soil on nutrients is improved; by adding the potassium nitrate, the zinc sulfate and the like, the matching of fast effect and slow effect nutrients in the fertilizer is improved, the soil fertilizer supply condition is dynamically adjusted, the continuous supplying capacity with soil being fertilizer sources is enhanced, and the wheat straw biochar fertilizer can have a nutrient supporting effect on crop growth for a long time.
Description
technical field [0001] The invention relates to the technical field of fertilizers, in particular to a wheat straw biochar fertilizer for long-term fertilizer supply 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 agricult...
