Problems solved by technology

[0006] The soil conditioner in the above two patent documents has the function of repairing saline-alkali land, but its composition is complex, and the wood vinegar used in the formula is a by-product of industrial charcoal production. The difference in composition and performance will cause its composition and performance to be unstable, which will easily affect the conditioning effect on saline-alkali soil

Abstract

The invention provides a soil conditioner and a preparation method thereof. The soil conditioner includes the following components in parts by weight: 20-40 parts of wood vinegar, 50-70 parts of a vegetable waste rotten material and 10-30 parts of a filler. According to the soil conditioner provided by the invention, the wood vinegar, the vegetable waste rotten material and the filler are compounded according to a certain ratio, and the three components cooperate with one another and synergize, and can effectively restore and improve soil salinization; and in addition, the wood vinegar in thesoil conditioner is obtained by carbonizing fruit tree branches, collecting smoke, performing condensation and performing filtering, the vegetable waste rotten material is obtained by fermenting wasteof vegetables in a greenhouse, both the wood vinegar and the vegetable waste rotten material effectively use the agricultural organic waste, so that recycling and reuse of resources are realized, andthe soil conditioner is environmentally friendly and efficient.

Description

technical field [0001] The invention belongs to the technical field of soil improvement, and in particular relates to a soil conditioner and a preparation method thereof. Background technique [0002] Saline-alkali soil is a general term for all kinds of saline soil, alkaline soil and different degrees of salinized and alkalized soil. Because the soil contains a large amount of saline-alkali components and has bad physical and chemical properties, the growth of plants is inhibited. According to the statistics of the second national census of the Ministry of Agriculture, the total area of ​​saline-alkali soil resources in my country is about 3467×10 4 hm 2 , while the saline-alkali soil area that has been reclaimed and planted is only 577×10 4 hm 2 , the salinized area of ​​cultivated land reached 920.9×10 4 hm 2 , accounting for about 6.62% of the total cultivated land area. [0003] Agricultural organic waste is mainly composed of livestock and poultry manure, crop st...
