Description
Technical Field
The utility model relates to the field of agricultural machinery, concretely relates to a multiple crusher for returning straw to field completely.
Background
The straw returning can fertilize the land capability, and can also reduce the atmospheric pollution caused by straw burning and increase the fertilizer and the yield. The crop straw contains certain nutrients, cellulose, hemicellulose, lignin, protein and ash elements, has more organic matters and also has nutrient elements such as nitrogen, phosphorus, potassium and the like. If the straw is transported away from the field, the organic matter remained in the soil is only about 10 percent, which causes the soil fertility to be reduced. Then, the fertilizer can be supplemented only by fertilizing or returning the straws to the field. The straw returning promotes the activity of microorganisms. Soil microorganisms have important functions of decomposing soil organic matters and purifying soil in the whole agricultural ecological system. The straw returning increases a large amount of energy substances for soil microorganisms, the number of various microorganisms and the enzyme activity are correspondingly increased, so that the decomposition of organic substances and the conversion of mineral nutrients are accelerated, the elements such as nitrogen, phosphorus, potassium and the like in the soil are increased, and the effectiveness of the soil nutrients is also improved. The black colloid substances such as cellulose, lignin, polysaccharide, humic acid and the like generated after the decomposition and conversion of the microorganisms have the capability of binding soil particles, form an organic and inorganic complex with clay minerals, promote the soil to form a granular structure, reduce the soil capacity, increase the coordination capability of water, fertilizer, gas and heat in the soil, improve the water retention, fertilizer retention and fertilizer supply capability of the soil and improve the physical and chemical properties of the soil. The straw returning can reduce the usage amount of chemical fertilizer. The nitrogen absorbed by the crops is mainly from the original nitrogen in the soil. Only 23% -24% from the fertilizer, soil organics are still the most important for crop growth. Therefore, returning the straws to the field is an excellent method for making up the defects of long-term use of the fertilizer. The agricultural ecological environment can be improved by returning the straws to the field. 80% of straws in rural areas are mainly subjected to combustion treatment, so that air pollution, traffic influence, soil surface layer coking and the like are caused, and sometimes fire disasters are caused. In addition, the agricultural ecological environment is also influenced by the random disposal of the straws. Therefore, the straw returning is beneficial to realizing the comprehensive utilization of agricultural wastes.
During the process of returning the straws to the field, various straws are harvested and then preferably immediately ploughed into the soil to avoid water loss and be difficult to decompose, attention is paid to the field, and the straws are cut up by a machine with enough horsepower, so that the decomposition of the straws can be accelerated, and the seeding and seedling emergence are not influenced.
