Description

TECHNICAL FIELD

[0001] The utility model relates to wheat straw bundling technical field more specifically, relate to a kind of wheat straw bundling device for saline-alkali soil biological composite interlayer. BACKGROUND

[0002] Saline-alkali soil refers to the land containing excessive salt and alkaline substances in soil, which has low soil fertility, high salt content and serious soil salinization, and has been a bottleneck restricting agricultural development. In order to improve saline-alkali soil and improve its agricultural productivity, scientists have proposed various technical methods, among which the biological composite interlayer technology is an effective method. This technology sets up a straw interlayer in the soil, uses the salt absorption and alkali resistance of straw, and improves the soil structure and increases the soil organic matter content to achieve the purpose of improving saline-alkali soil. Through straw deep burying tillage tools, crop straw is directly turned into deep soil layer to form a biomass interlayer. This layer of straw can change the capillary water and salt movement of the soil, effectively prevent salt from moving upward with water evaporation, form a "high water and low salt" microenvironment, and is beneficial to the growth and development of crop roots. As an organic material, straw can release nutrients after decomposition in the soil, increase soil organic matter content, improve soil structure, promote the formation of soil aggregates, and further improve soil fertility. The straw interlayer not only physically blocks salt, but also provides habitat for soil microorganisms, enhances soil microbial activity, promotes soil nutrient cycling and transformation, forms a biological composite effect, and further improves the improvement effect of saline-alkali soil.

[0003] In the biological composite interlayer technology of saline-alkali soil, the wheat straw bundling device plays a crucial role.

However, wheat straw is often scattered in the field, which is not convenient for direct use in soil improvement, and manual bundling has low efficiency.
