Wheat straw biochar fertilizer for sandy soil and preparation method thereof

Abstract

The invention discloses a wheat straw biochar fertilizer for sandy soil and a preparation method thereof. The wheat straw biochar fertilizer is prepared from the following raw materials in part by weight: 22-26 parts of tangerine seed powder, 3-4 parts of boric acid, 4-6 parts of sodium bicarbonate, 33-37 parts of bean cake powder, 35-39 parts of crushed bone meal, 12-16 parts of maple syrup, 2-3 parts of silicon sulfate, 110-130 parts of fresh enteromorpha, 5-6 parts of composite microbial agent, 245-255 parts of wheat straw, 26-30 parts of fresh urine, and a proper amount of water. The wheat straw biochar fertilizer employs organic matters as main raw materials, and needs of sandy soil plantation are met in cooperation with high adsorptivity of the biochar; the wheat straw biochar fertilizer has the advantages of good fertilizer conservation and water retention capabilities, the soil temperature is buffered, day and night temperature difference is reduced, and later nutrient demands of crops are ensured; in addition, by means of good permeability of sandy soil, aerobic activities of microbes added in the fertilizer increase, decomposition of organic matters in the fertilizer can be promoted, therefore the utilization rate of the fertilizer is raised and the soil fertility is raised.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a wheat straw biochar fertilizer for sandy soil texture 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 prod...

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.
