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.

Embodiment 1

[0039] A method of using microbial preparations to stack retting and return to the field, the steps are as follows:

[0040] (1) Transport the straw to the edge of the ground or low-lying land nearby, excavate the surrounding soil to raise more than 30cm, flatten the bottom of the pile, and tap it firmly to prevent running water;

[0041] (2) The width of straw stacking is 2.0 meters, the height is 1.5 meters, and the length is not limited;

[0042] (3) Dilute the microbial preparation with 10 times the weight of water one day in advance (it is beneficial to restore and enhance the vitality and activity of the bacteria, and improve the efficiency of the decomposing agent to decompose the straw) to obtain the diluted bacterial agent, and add the diluted bacterial agent according to 20% of the weight of the straw, After mixing evenly, ferment at room temperature. During the fermentation process, detect the temperature of the fermented product. When the temperature rises above 60...

Embodiment 2

[0060] A method of using microbial preparations to stack retting and return to the field, the steps are as follows:

[0061] (1) Transport the straw to the edge of the ground or low-lying land nearby, excavate the surrounding soil to raise more than 30cm, flatten the bottom of the pile, and tap it firmly to prevent running water;

[0062] (2) The width of straw stacking is 1.5 meters, the height is 1.8 meters, and the length is not limited;

[0063] (3) Dilute the microbial preparation with 10 times the weight of water one day in advance (it is beneficial to restore and enhance the vitality and activity of the bacteria, and improve the efficiency of the decomposing agent to decompose the straw) to obtain the diluted bacterial agent, and add the diluted bacterial agent according to 30% of the weight of the straw. After mixing evenly, ferment at room temperature. During the fermentation process, detect the temperature of the fermented product. When the temperature rises above 60...

Embodiment 3

[0080] Example 3: Effects of returning crop straws to the plow layer soil

[0081] 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:

[0082]

[0083]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 method for returning straws into a field through stack retting by using a microbial preparation. The method comprises the following steps: conveying the straws into the nearby field; digging channels in the periphery of the field and carrying out ridging by a distance which is 30 cm or above; flattening a stack bottom, wherein the width of a straw stack is 1.5-2.0 meters, and the height of the straw stack is 1.5-1.8 meters; adding a dilute microbial inoculum which accounts for 20-30% of the weight of the straws to obtain a matured product; adding a compost preparation under the condition that the ratio of the matured product to the compost preparation is 3: 2; and after the matured product and the compost preparation are mixed uniformly, tightly sealing the mixture by using mud or black plastic agricultural films, and fermenting for 10 days to obtain straw fermented organic fertilizers. The straws can be directly returned into the field.

Description

technical field [0001] The invention belongs to the technical field of microbes, and in particular relates to a method for stacking and retting straws using microbial preparations and returning them to fields. 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...
