Description

Plows for soil plowing and straw deep burial

technical field

The invention relates to soil cultivation technology, in particular to a plow used for soil plowing and straw deep burial and returning to the field.

Background technique

Soil is an important material carrier for agricultural production. Reasonable tillage layer structure and soil fertility are directly related to the high and stable yield and sustainable development of crops. Reasonable tillage layer structure can maintain soil bulk density, coordinate soil regulation ability, and then coordinate and Make the soil have suitable water, fertilizer, air and heat conditions. On the one hand, suitable water, fertilizer, air and heat conditions can better promote the mineralization of the plow layer, accelerate the release of nutrients in the plow layer, and thus provide a good soil environment for crop roots; On the other hand, suitable water, fertilizer, air and heat conditions can better promote humification in the plow layer, preserve and accumulate organic matter, and fertilize the soil. Fertile soil can provide sufficient nutrients for the growth of crops, thereby ensuring High and stable crop yields.

At present, my country is facing the huge pressure of rapid population increase and sharp decrease of cultivated land. Therefore, improving the reasonable structure of the soil and improving soil fertility is one of the main ways to achieve high, stable and sustainable crop yields. In the prior art, technologies such as plow plowing, chisel-shaped shovel deep loosening, and rotary plowing are mainly used to plow the soil, and the straw on the surface of the soil is plowed to the furrow plowed by the plow last time. And plow the crop residues in the soil to the surface of the soil to form the plow layer structure of the soil. Although the above techniques have a certain effect on loosening the soil, it is difficult for these farming methods to plow the straw on the soil surface to the furrow that was plowed last time by the plow. For example, when the straw is long, it may be put on hold. On the plow, it cannot be buried in the furrow, so that straw remains on the surface of the soil. At the same time, the crop residue in the soil cannot be effectively plowed to the furrow, and the crop residue and straw are often mixed in different plow layers. In the soil, the quality of tillage is low, the quality of land preparation after tillage is not good, and the soil ventilation and air leakage are serious, which makes it difficult for the soil to form suitable water, fertilizer, gas and heat conditions. The release of nutrients in the soil is slow; on the other hand, it makes it difficult for crop residues and straw to rot, and also inhibits the humification in the plow layer, and cannot preserve and accumulate organic matter. Due to the inability to form suitable water, fertilizer, gas and heat conditions in the plow layer structure, it affects the emergence and growth of crops. For example, the emergence rate of crops is low and the growth is slow, thereby reducing crop yield.
