Segmented comprehensive utilization mode for corn straw

Abstract

The invention provides a method for achieving segmented comprehensive utilization for corn straw. Corn lodging resistance is achieved, and corn direct harvesting and yield and income increasing are promoted. According to the technical scheme, the segmented comprehensive utilization mode for the corn straw is characterized by including the steps that the portions, above corn cobs, of plants are cut at a corn wax ripeness stage, cut corn plants are recycled and smashed to serve as silage, corn is subjected to mechanical grain direct harvesting after a corn complete ripeness stage, and the harvested corn plants are recycled and smashed to serve as yellow corn silage.

Description

technical field [0001] The invention relates to a segmented comprehensive utilization mode of corn stalks. Background technique [0002] With the rapid development of science and technology and the continuous improvement of farmers' living standards, the technology of agricultural production is also developing rapidly, and the technology of increasing grain production and income is also becoming more and more perfect. Mainly fertilizer. However, relying solely on the application of chemical fertilizers has caused great harm to the soil and the environment, and scientific management and technology are needed to compensate for the negative impacts of chemical fertilizers. When corn grows to the middle and late stages, the height of the plant increases and the nutrients required increase, which requires scientific protection and maintenance of corn. [0003] At present, corn stalks have changed from a valuable fuel resource for farmers to "useless to keep, and it is a pity to...

Problems solved by technology

[0003] At present, corn stalks have changed from a valuable fuel resource for farmers to "useless to keep, and it is a pity to discard them." The treatment of corn stalks has always been the most troublesome thing for the government and farmers, and it is a major issue in the utilization of agricultural organic waste resources. Difficulties. When using a corn combine harvester to harvest corn, crushing the whole corn stalk and returning it to the field has the problems of high water content in the corn stalk, high energy consumption for crushing, and affecting the operating efficiency and reliability of the corn combine harvester. After the corn stalk is crushed, it must be Landfill treatment will increase the cost of mechanical operations, and because the whole corn stalks are crushed due to the high lignin and cellulose content, it is difficult to be used by microorganisms in the soil, which will affect the cultivation of crops in the next year, and the effect of returning the straw to the field is poor. Other better solutions can only be treated by incineration. Corn stalks are burned in the field, which pollutes the environment and is the main cause of smog in spring and autumn. This will not only reduce the content of soil organic matter, but also affect air quality and traffic. , fires are endless, "straw burning" has caused serious pollution to the environment, and it is also a pollution problem that plagues the national air environment. The government strictly prohibits the burning of straw
