Description
Technical Field
The invention belongs to the field of agricultural machinery, and particularly relates to a seedbed finishing device under the condition of covering and returning corn straws to fields.
Background
Protective farming, which takes straw returning as a main technical measure, becomes a main way for improving soil structure and ecological function.
With the implementation of the outline of the protection planning for black soil in northeast China (2017-2030), the implementation scheme of the engineering for protecting black soil in China (2021-2025), etc., the returning of straws to fields has gradually been accepted by most farmers and become a common consensus, wherein protective farming in a main technical mode of covering and returning straws to fields and moving less soil is one of the current major technologies. However, due to the fact that the corn biomass in the affected area is large, the ridge distance is small, the existing machine and tools are not matched with agriculture, and the like, under the condition of straw coverage and field returning, particularly under the condition of full field returning, the straw at the position of a seedbed is difficult to clean, the flatness of the seedbed is poor, so that the phenomena of different sowing depths under the no-tillage condition, poor seedling quality and the like are common, the technical effect is influenced, and the main bottleneck that the large-area popularization of the corn straw coverage and field returning technical area is limited is further formed.
Therefore, the key for solving the problems under the current condition is to create a reasonable seedbed structure under the condition of returning straws to the field and improve the seedling emergence quality of seeds. For this reason, some attempts and innovations have been made by regional authorities and scientific research institutions. For example, the occurrence of a straw row-grouping shallow layering tillage machine (No. CN211481870U) and a double-row deep loosening rotary tillage compacting strip tillage machine (No. CN 214228800U) plays an important role in solving the problems of large straw amount in a region, returning straws to fields and the like. However, these machines mainly adopt shallow rotary tillage or strip rotary tillage in the field of soil preparation, which firstly results in a large proportion (more than 50%) of moving soil and large disturbance and destructiveness to the soil, which is contrary to the basic principle of protective farming; secondly, the power consumption is large. Therefore, the development of the tillage machinery based on straw covering and returning, which can create a leveling seedbed structure, has small soil moving proportion and low power consumption, has an important promoting effect on large-area popularization of a protective tillage area.
Since 2015, Jilin province agricultural academy and province related units carry out systematic analysis and investigation on related agricultural indexes such as soil water temperature change, seedbed structure and quality, miss-seeding rate, emergence rate and emergence uniformity under the condition of straw mulching and returning field no-tillage planting under the support of projects such as national science and technology support technology, province major technology collaborative popularization and the like. Through field observation and experimental verification for many years, the invention realizes the integrated innovation of seedbed land preparation machinery by optimizing a deep scarification part, optimizing the layout of a deep scarification hook and a soil cutting rake and upgrading a compacting and crushing device, finally realizes the field preparation operation target under the condition of two-reduction-one-excellent straw coverage and field returning such as reducing power consumption and soil disturbance, building a good seedbed structure and the like, provides mature and reliable agricultural operation machines and tools for straw returning to the field under the protective cultivation condition of the black soil in northeast of China under the current condition, and realizes the organic fusion of agricultural machines.
