Abstract
The invention discloses a method for improving straw returning soil, which comprises the steps of crushing straw, uniformly throwing the crushed straw into soil with the humidity of 50% -60%, throwing BFA fermentation inoculant at the amount of 15 kg-25 kg per mu, and turning over the soil with the straw and the BFA fermentation inoculant, so that the straw, the BFA fermentation inoculant and the soil are fully mixed, and the straw can be thoroughly decomposed in 7 days under the environment of 20 ℃. The method can rapidly and massively treat the straws; under the action of BFA fermentation inoculant, the straw decomposition speed is high; the straw contains a large amount of organic carbon sources and nitrogen, phosphorus and potassium nutrient contents, and the straw returning can increase soil organic matters and nutrients, improve soil physical properties, promote soil aggregate structure formation, improve the activities of soil microorganisms and soil enzymes, enhance the water-retaining drought-resistant capacity of farmlands, reduce the fertilizer consumption and increase the crop yield; reduces the environmental damage caused by incineration and is beneficial to the recycling of resources.
Description
Technical Field
The invention relates to the technical field of soil improvement methods, in particular to a method for improving straw returning soil.
Background
The straw resources in China are rich, the theoretical resource amount of the straw in China is 8.55 hundred million tons in 2017 according to the published and investigated statistics of the national statistical bureau, and the collectable resource amount is about 7.36 hundred million tons. Wherein, the rice straw accounts for 25.1 percent, and the collecting amount is 1.85 hundred million tons. Along with the development of science and technology, ecological agriculture is a development direction of modern agriculture, straw is reused as precious resources, and straw returning directly is one of main ways. At present, the straw returning is usually burnt, the straw is burnt into carbon ash and then is remained in soil, the method causes atmospheric pollution, the resource utilization of the straw is not facilitated, the physical, chemical and biological properties of the soil are difficult to change or improve, the method is not suitable for large-scale production, the national policy has strict requirements for prohibiting the burning and the comprehensive utilization, and therefore, I develop a method for improving the straw returning soil, which is used for solving the problems.
Disclosure of Invention
The invention aims to overcome the existing defects and provide a method for improving straw returning soil, which can effectively solve the problems in the background technology.
In order to achieve the above purpose, the present invention provides the following technical solutions: a method for improving straw returning soil comprises the following steps:
step one, crushing straws;
step two, uniformly throwing the crushed straws onto soil;
uniformly spraying BFA fermentation inoculant on the soil on which the straw scraps are thrown;
and fourthly, ploughing the land on which the straw and the BFA fermentation inoculant are thrown, so that the straw, the BFA fermentation inoculant and the soil are fully mixed.
As a preferable technical scheme of the invention, the humidity of the soil is ensured to be 50% -60% before throwing the straw powder in the second step.
As a preferable technical scheme of the invention, the sprinkling amount of the BFA fermentation inoculant in the third step is 15 kg-25 kg per mu.
In the fourth step, the straw, the BFA fermentation inoculant and the soil are fully mixed, and then straw scraps are thoroughly decomposed within 7 days at the temperature of 20 ℃.
Compared with the prior art, the invention has the beneficial effects that:
1. the straw can be rapidly and massively processed;
2. under the action of BFA fermentation inoculant, the straw decomposition speed is high;
3. the straw contains a large amount of organic carbon sources and nitrogen, phosphorus and potassium nutrient contents, and the straw returning can increase soil organic matters and nutrients, improve soil physical properties, promote soil aggregate structure formation, improve the activities of soil microorganisms and soil enzymes, enhance the water-retaining drought-resistant capacity of farmlands, reduce the fertilizer consumption and increase the crop yield;
4. reduces the environmental damage caused by incineration and is beneficial to the recycling of resources.
Detailed Description
The following description of the technical solutions in the embodiments of the present invention will be clear and complete, and it is obvious that the described embodiments are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The invention provides a technical scheme that: a method for improving the soil of returning straw to field, namely, after the straw is crushed, the crushed straw is evenly thrown into the soil with the humidity of 50% -60%, the wet soil is helpful for decomposing the straw, then BFA fermentation inoculant is thrown in the amount of 15 kg-25 kg per mu, BFA fermentation inoculant adopts BFA fermentation inoculant product with the publication number of CN1535936A produced by Fujian oasis Biochemical Co, the limited viable count of the product is more than or equal to 2 hundred million per gram, the product is rich in organic carbon nutrients and a large amount of beneficial bacteria, the method is suitable for the purposes of organic fertilizer fermentation, soil improvement, plant root promotion, straw returning and the like, the beneficial bacteria group in the method can carry out quick propagation work by carrying out quick fermentation on the straw, the BFA fermentation inoculant can carry out quick decomposition on the straw in a moist environment, the soil with the straw and the BFA fermentation inoculant is turned over, the straw, the BFA fermentation inoculant and the soil are fully mixed, and the crushed straw can be completely decomposed in 7 days at 20 ℃;
the quick decomposition of the straw powder has the following advantages: the defect that soil moisture conservation and water conservation are not facilitated due to too large soil pores can be avoided as excessive straws enter the soil to influence the contact between seeds and root systems and the soil; avoiding the accumulation of diseases and insect pests caused by the fact that the straws enter soil after being naturally decomposed and returned to the field; avoiding the phenomena of floating and air bubbles generated by undegraded straws in the field, and further avoiding the root rot and growth stagnation of rice caused by the air bubbles;
the decomposed straw contains a large amount of organic carbon sources, nitrogen, phosphorus, potassium and other nutrients, so that the organic matters and the nutrients of the soil can be increased, the soil fertility can be effectively improved, the physical properties of the soil can be improved, the formation of soil aggregate structures can be promoted, the activities of soil microorganisms and soil enzymes can be improved, the water-retaining drought-resistant capacity of farmlands can be enhanced, the fertilizer consumption can be reduced, and the crop yield can be increased.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
