Thermal-insulation wheat straw biocarbon fertilizer and preparation method thereof

Abstract

The invention discloses a thermal-insulation wheat straw biocarbon fertilizer and a preparation method thereof. The fertilizer is composed of the following raw materials in parts by weight: 30 to 40 parts of aquatic product leftovers, 12 to 16 parts of palygorskite, 6 to 8 parts of manganese fulvate, 5 to 7 parts of triple superphosphate, 4 to 5 parts of tartaric acid powder, 4 to 8 parts of calcium ammonium nitrate, 26 to 34 parts of rice bran, 120 to 140 parts of fresh enteromorpha, 5 to 6 parts of composite microbial inoculant, 230 to 240 parts of wheat straw, 29 to 31 parts of fresh urine, and a proper amount of water. The provided biocarbon fertilizer has rich and balanced nutrients; the waste resources such as wheat straw, aquatic product leftovers, and the like are recycled and reused; the added tartaric acid powder can improve the performance of fertilizer on chelating nutrients, at the same time, and the biocarbon fertilizer particle has a dark color, the color of topsoil becomes darker and darker as the content of biocarbon fertilizer increases, so the soil can absorb the thermal energy of UV rays and visible light, the temperature of topsoil is increased, and the temperature of the cultivation layer can be well maintained.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a wheat straw biochar fertilizer with heat preservation effect 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 agricultur...

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.
