Problems solved by technology

[0010] The present invention aims to solve the problem of the prior art in straw stack retting. Due to the high carbon-nitrogen ratio of straw, it is difficult to be decomposed by microorganisms in the natural state, resulting in a long period of decomposition and transformation in the soil after the straw is returned to the field, and it is difficult to be used as a seasonal crop. Fertilizer problem

Embodiment 3

[0083] Example 3: Effects of returning crop straws to the plow layer soil

[0084] The method of returning corn stalks to the field in Example 1-2 is used to improve soil fertility. When the corn stalks are mechanically returned to the field, the application rate of corn stalks is 300kg / mu, and the plow layer soil before the test and after 1 year of the test is collected respectively, and analyzed. The basic physical and chemical values, the specific results are shown in Table 1:

[0085]

[0086]It can be seen from Table 1 that after adopting the method of returning corn stalks to the field in Example 1-2, the physical and chemical properties of the soil have been greatly changed. Soil bulk density increases soil porosity. However, when corn stalks are mechanically returned to the field, the increments of nitrogen and phosphorus elements in the soil after the rotted straws are smaller than those in Example 1 and Example 2, because the nitrogen and phosphorus elemen...

Abstract

The invention provides a biological agent used for straw composting. The biological agent comprises a composting agent and a compost agent, wherein the composting agent is prepared from a composite bacteria liquid and carriers in a weight ratio of 2 to 3; the compost agent is prepared from a cake powder, lime and urea in a weight ratio of 7-8 to 4-5 to 3-4. According to the biological agent provided by the invention, the materials is thoroughly composted in the straw treatment process, and a large quantity of functional microorganisms and various metabolites such as plant hormones and antibiotics are generated, so that the growth and the development of crops are stimulated, the soil nutrient is improved, the soil structure is improved, the utilization rate of chemical fertilizers is improved, and the biological agent is simple and convenient in operation and beneficial for production.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a biological preparation for straw stack retting. Background technique [0002] According to investigations, in recent years, the basic fertility of soil has decreased, and the content of soil organic matter has decreased, which has seriously restricted the improvement of crop yield and quality. The implementation of straw composting and returning to the field can effectively increase the content of soil organic matter, change the physical and chemical properties of the soil year by year, and achieve good effects of improving soil and fertilizing soil fertility. Therefore, straw stacking and retting is an important way to maintain and improve soil fertility, and it is a way out to solve the current problem of crop straw utilization. Crop straw contains a large amount of organic matter, nitrogen, phosphorus, potassium and trace elements, and is one of...
