Saline-alkali soil micro-domain improved sowing device

Abstract

The invention discloses a saline-alkali soil micro-domain improved sowing device which comprises a frame. A furrow opener, a water injection mechanism, a soil breaking mechanism, a matrix preparationmechanism and a sowing mechanism are sequentially arranged in the frame from left to right; during sowing, the furrow opener firstly performs furrowing, the water injection mechanism injects water into furrows, and the soil breaking mechanism breaks soil blocks; and then soil and a matrix are mixed according to a certain proportion through the matrix preparation mechanism and then stirred in a stirring barrel, a first feeding mechanism conveys the matrix from the left end to fall off, the first layer of matrix is laid in the furrows, the sowing mechanism sows on the first layer of matrix, andthen a second feeding mechanism conveys the matrix to fall off to cover seeds. Sowing is completed, the automation degree is high, the labor intensity is reduced, and the sowing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of sowing in saline-alkali soil, in particular to a micro-field improved sowing device for saline-alkali soil. Background technique [0002] The biggest feature of saline-alkali land is compaction, barren land, and difficulty in seedling emergence. The key to planting crops in saline-alkali land is to get seedlings. Most crops in saline-alkali land, especially small-grained grains such as quinoa, millet, and sorghum, are sown early and shallow (usually at the end of March At the beginning of April), at this time, the saline-alkali land is windy and loses moisture quickly, the ground temperature is low and the emergence is slow, and the compacted soil is prone to make it difficult for seeds to emerge in the air. Spring is the season when the saline-alkali land returns to salinity. These factors are important reasons for affecting germination. . The most important environment for seed germination and emergenc...

Problems solved by technology

[0003] However, the current production is to comprehensively improve the soil by applying organic materials, organic fertilizers and other measures, which are expensive, ineffective, and easy to repeat.

The same equipment and seeding techniques as those in non-saline-alkali land are used for sowing, so it is difficult to solve the problem of slow seedling emergence, difficult seedling emergence, uneven seedlings and weak seedlings in saline-alkali land.

Greatly affected the production efficiency of saline-alkali land
