Rice straw total returning and field management integrated method

Abstract

The invention discloses a rice straw total returning and field management integrated method. The method comprises the following steps: S1, rice straw returning treatment; s2, field steeping; s3, pulping; s4, field management; s5, disease and pest control; according to the technical method, agricultural machinery commonly used by farmers is used for treating rice straw, turning, pressing and returning the rice straw to the field, and the rice straw is soaked in water and dried in the sun, and the rice yield can be stabilized or increased through the irrigation mode of alternation of wetting and drying after drying; the content of organic matters in the soil and the content of available nitrogen, phosphorus and potassium in the soil can be increased by about 0.3 g / kg every year, the bulk density of the soil is reduced, and the adhesiveness of the soil is reduced; the influence of reducing substances generated by rice straw floating and rice straw returning to the field on rice root systems is solved, and a series of problems of environmental pollution and the like caused by rice straw incineration can be solved; the soil conditioner can be basically suitable for most soil environments in wet-drought climate, is wide in application area and good in environmental protection property, and improves the soil fertility; meanwhile, a way is found for an environment-friendly treatment mode of the rice straws.

Description

technical field [0001] The invention relates to the field of utilization of agricultural resources, in particular to an integrated method for returning full rice stalks to the field and field management. Background technique [0002] In recent years, the degradation of the "giant panda" in the cultivated land of black land in Northeast China has attracted great attention from the central government to local governments. Measures have been introduced in various parts of the Northeast to solve the problem of thinning, thinning and hardening of black land in Northeast China. It is regarded as the most effective and economical technical measure to protect the black soil. Straw is rich in various nutrients necessary for plants. Straw returning to the field can provide a rich carbon source for microorganisms in the soil, improve soil fertility, and then increase crop yield; straw returning to the field can promote the recycling of soil nutrients and reduce the amount of chemical f...

Problems solved by technology

However, up to now, the technology of straw returning of upland crops is relatively mature (for example, the techniques of returning corn straw to the field by pressing, mulching, and crushing and mixing are quite mature, and the promotion area is also increasing year by year). Returning to the field has been in the experimental demonstration stage. There are three main reasons: first, reducing substances such as ferrous iron and hydrogen sulfide will be produced during the process of rice straw returning to the field to rot, which will harm the growth of rice roots; Competing for nutrients affects the growth of rice; third, rice stalks tend to float during the process of returning to the field, and it takes a lot of work to catch stubble, which affects the enthusiasm of farmers

[0003] These problems have not found an effective solution, which has affected the large-scale promotion of rice straw returning technology.
