Problems solved by technology

[0007] Although straw returning to the field has a long history and there are many studies, it is difficult to realize the full amount of corn straw returning to the field in production so far, and most of them are partial returning (about 1 / 3 of the amount)
In addition, the full amount of straw returning to the field can only be realized in indoor simulation experiments or field plot experiments. It is more common in the writing and publication of papers, but it is not practical.
Based on actual production, it is mostly in the trial stage to realize the full amount of corn stalks returning to the field, and problems such as preserved seedlings and straw decomposition are difficult to solve

Abstract

The invention relates to a planting method based on total returning of corn straws to a field. The planting method provided by the invention can effectively solve the problem of serious waste of straw resources, and completely eradicates the problems like air pollution, soil surface coking and traffic jam caused by straw burning and random disposal. Meanwhile, through implementation of the method provided by the invention, nutrient elements like nitrogen, phosphorus and potassium in soil are supplemented; soil organic matters are increased; soil fertility is improved; the phenomenon of soil pollution caused by large quantity application of a chemical fertilizer is reduced; the agricultural ecological environment is improved; the sustainable utilization of black soil resources is promoted; and the rapid development of agricultural modernization is pushed.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a planting method based on returning full corn stalks to the field. Background technique [0002] Corn is the largest crop in the world and also the largest crop in my country. Northeast my country is one of the main corn production areas in China. The annual output of corn stalks is close to 70 billion catties. Disposal of a large amount of corn stalks has become a difficult problem for farmers and the government. At present, in the Northeast, 70% of the straw is discarded and burned, and the problems caused by it, such as air pollution and ecological environment deterioration, are becoming more and more obvious. [0003] At present, farmland operations in Northeast China are mainly powered by small four-wheel machinery, and the straw returning is mainly root stubble returning to the field, and the full amount of straw cannot be returned to the field. The main reasons are: [0004]...
