Ecological environment-friendly fertilizer additive containing charcoal and preparation method thereof

Abstract

An ecological environment-friendly fertilizer additive is prepared from, by weight, 10-40 parts of charcoal, 10-30 parts of sepiolite, 10-20 parts of tea seed cakes, 5-30 parts of lime and 10-20 parts of tung seed cakes in a mixed mode. A preparation method of the ecological environment-friendly fertilizer additive containing the charcoal comprises the steps that firstly, the raw materials are got according to the ratios of parts by weight, the charcoal and the lime are smashed into 20-60-mesh powder, the sepiolite, the tea seed cakes and the tung seed cakes are subjected to impurity removing and dried and then smashed into 20-60-mesh powder; secondly, the charcoal powder, the sepiolite powder, the tea seed cake powder, the lime powder and the tung seed cake powder which are obtained in the first step are mixed, and the product is obtained; or the raw materials are mixed and then smashed, and the product is obtained. The ecological environment-friendly fertilizer additive containing the charcoal can prevent caking of fertilizers, improve soil, reduce heavy metal, prevent and treat crop diseases and pests and increase the agricultural output when added into the fertilizers.

Description

technical field [0001] The invention relates to the technical field of eco-environmental protection fertilizer additives, in particular to an eco-environmental protection fertilizer additive containing biochar and a preparation method thereof. Background technique [0002] Biochar (English: Biochar), also known as agricultural carbon (English: Agrichar), is charcoal used for agricultural purposes. It is a solid product produced by pyrolysis in an anoxic or anaerobic environment, after low-temperature pyrolysis. The main ingredient is carbon molecules. Unlike ordinary charcoal, it is not used as fuel, but is used to improve soil, help plants grow, and carbon capture and storage. Biochar is a bio-organic material (biomass) that can be used not only as a high-quality energy source, a soil improver, but also as a reducing agent, fertilizer slow-release carrier, and carbon dioxide sequestration agent. Adsorption and soil improvement, etc., have the functions of controlling envi...

Problems solved by technology

[0008] The technical problem to be solved by the present invention is: to overcome the agricultural fertilizers of the prior art in preventing chemical fertilizer agglomeration, adjusting soil pH, preventing volatilization and loss of active ingredients of chemical fertilizers, reducing the amount of fertilizer applied to crops, improving soil, reducing heavy metals in agricultural products, preventing and controlling There are deficiencies in crop diseases and insect pests, increasing the yield of crops and reducing environmental pollution. In order to meet people's wishes, an ecological and environmentally friendly fertilizer additive containing biochar and its preparation method are provided. The ecological and environmentally friendly fertilizer containing biochar The addition of additives to agricultural fertilizers can prevent the formation of chemical fertilizer "salt bridges" and prevent chemical fertilizer agglomeration. After use, it can adjust the pH of the soil, prevent the volatilization and loss of active ingredients in chemical fertilizers, reduce the amount of fertilizer applied to crops, improve the soil, and reduce heavy metals in agricultural products. Prevent and control crop diseases and insect pests, increase the yield of crops, and reduce environmental pollution; the present invention uses the respective characteristics of biochar, sepiolite, tea dry, lime and tung tree dry to achieve mutual coordination and promotion after physical mixing, which can prevent Fertilizer "salt bridge" forms to prevent fertilizer agglomeration, slow release of fertilizer, improve its utilization rate, reduce fertilization, reduce heavy metals, reduce environmental pollution, increase drought resistance of crops, adjust soil pH, reduce heavy metals, prevent crop diseases and insect pests, improve Crop quality and yield
