Problems solved by technology

[0002] Saline-alkali land is a type of salt accumulation. The salt contained in the soil affects the normal growth of crops and will destroy the normal structure of the soil. The current improvement methods generally include water conservancy improvement, agricultural technology improvement, chemical improvement and biological improvement. , biological improvement generally uses methods such as returning straw to the field. When using straw, the degree of refinement of straw is not enough, which affects the post-treatment of straw, especially when dealing with hard straw. The existing processing equipment has certain shortcomings, and in In the post-processing of straw, it is inconvenient to turn over

Embodiment Construction

[0028] A preparation process of a saline-alkali soil conditioner, comprising the following steps:

[0029] Step A: using the straw pretreatment device (1) to pretreat the straw;

[0030] Step B: sterilizing and killing insects on the pretreated straw;

[0031] Step C: mixing the sterilized and insecticided straw with a soil structure improver and an organic alkali-reducing raw material, and performing composting;

[0032] Step D: turning the composted material by using the turning device (5).

[0033] Such as Figure 1-2As shown, the straw pretreatment device 1 includes a housing 101, the lower section of the housing 101 is cylindrical, and the top side of the housing 101 is provided with a first pressure roller 103. The other side of the top of 101 is provided with a fixed frame 104, and a spring telescopic rod 105 is fixedly connected in the fixed frame 104, and the other end of the spring telescopic rod 105 is provided with a second pressure roller 106, and the first pre...

Abstract

The invention discloses a preparation process of a saline-alkali soil improver, which comprises the following steps: using a straw pretreatment device to pretreat the straw, sterilizing the pretreated straw, and killing the sterilized and insecticided straw. Mix with soil structure improver and organic alkali-reducing raw materials, and perform composting treatment, and use the composting device to turn the composted materials. In the present invention, the straw pretreatment device can be used to finely crush the straw, thereby facilitating composting, improving the efficiency of composting, and accelerating the decomposition of the straw. The strength of the straw is reduced, and the degree of subsequent refinement is directly improved. The cam cutter head is a cam disc-shaped structure, which has higher strength, and the cutting depth gradually deepens. It can smoothly split the harder straw.

Description

technical field [0001] The invention relates to the technical field of saline-alkali soil improver preparation. Specifically, it is a preparation process of a saline-alkali soil conditioner. Background technique [0002] Saline-alkali land is a type of salt accumulation. The salt contained in the soil affects the normal growth of crops and will destroy the normal structure of the soil. The current improvement methods generally include water conservancy improvement, agricultural technology improvement, chemical improvement and biological improvement. , biological improvement generally uses methods such as returning straw to the field. When using straw, the degree of refinement of straw is not enough, which affects the post-treatment of straw, especially when dealing with hard straw. The existing processing equipment has certain shortcomings, and in During post-processing of straw, it is inconvenient to turn over. Contents of the invention [0003] Therefore, the technical...
