Problems solved by technology

In recent years, due to the application of a large amount of chemical fertilizers and less use of organic fertilizers in farmland, soil compaction, low soil organic matter, soil pollution, and soil loss of vitality have caused the soil to be in a sub-healthy state.
The method of directly returning straw to the field can increase soil organic matter and improve soil physical and chemical properties, but the straw decomposes slowly, and its active ingredients are rarely used by crops in the current season, which is not conducive to farmland operations. Therefore, a crop straw decomposing agent is e

Embodiment 1

[0011] Demonstration effect of crop straw decomposing agent on wheat (corn straw)

[0012] 1 Materials and methods

[0013] 1.1 Materials for demonstration

[0014] The demonstration was arranged in the Waibanqiao Experimental Field of High-tech Park, Henan Province in October 2011. The soil used for the demonstration was Xiaoliang compound soil, the field surface was flat, the fertility was uniform, the drainage and irrigation were convenient, and the planting level was comparable to the local production level. Before the demonstration, the soil nutrient content was shown in Table 1. The stalks of the tested crops were corn stalks, the current season crops were wheat, the variety was Zhongmai No. 1, and the application method was returning the stalks to the field for plowing. The crop straw decomposing agent for demonstration was provided by Henan Baorong Biotechnology Co., Ltd.

Embodiment 2

[0043] 1 Materials and methods

[0044] 1.1 Test location: Yaocun Township, Langxi County, Anhui Province

[0045] 1.2 Soil for the test: the soil of the test field is paddy soil, organic matter 21.2g / kg, alkaline nitrogen 142mg / kg, available phosphorus 25.1mg / kg, available potassium 107mg / kg.

[0046] 1.3 Crop varieties tested: Jinan No. 17

[0047] 1.4 Experimental design

[0048] Treatment 1: conventional fertilization + straw returning to the field + crop straw decomposing agent

[0049] Conventional fertilization (N: 10kg / mu+P 2 o 5 2.4kg / mu+K 2 O3kg / mu) + straw return (6000kg / hm 2 )+Crop straw decomposing agent (a mixture made by mixing 2kg / mu with 20kg of fine soil). The crop straw decomposing agent is composed of the following mass ratios: 25% of Bacillus subtilis, 29% of Aspergillus niger, 14% of Candida utilis, 18% of Trichoderma viride, 12% of Aspergillus oryzae, and 2% of cellulase.

[0082] 1. Materials and methods

[0083] 1.1 The variety tested: Heng 4444

[0084] 1.2 Test location: Xiaobeiwang Village, Jiangwu Township, Yongnian County, Hebei Province

[0085] 1.3 Experimental design

[0086] The experiments were carried out in different plots, the distance between the two plots was 5 kilometers, and the soil conditions were quite different. Three treatments were set up in the experiment. Treatment 1: The experimental field in the south of Xiaobeiwang Village, with an area of ​​1,000 square meters, was treated with crop stalk decomposing agent. When corn was harvested, the corn stalks were broken up and spread evenly on the field. Before wheat sowing, at least 20 Every day, evenly sprinkle 2 kg / mu of crop straw decomposing agent, then plow and prepare the land, so that the crop straw decomposing agent and the soil of the plowing layer are fully mixed;

Abstract

The invention discloses a crop straw decomposition agent. The crop straw decomposition agent is composed of the following components by mass percent: 20%-30% of bacillus subtilis, 20%-30% of aspergillus niger, 10%-15% of candida utilis, 15%-20% of trichoderma viride, 10%-15% of aspergillus oryzae and 1%-2% of cellulase. In order to solve the problems such that current straws are directly returned to fields, and the temperature rise is slow, the decomposition is slow and the decomposition effect is poor when the straws are used for composting an organic fertilizer, crop straw decomposition is tested for a plurality of years, microorganism strains and biological enzyme preparations are continuously screened, and finally, the bacillus subtilis, the aspergillus niger, the candida utilis, the trichoderma viride, the aspergillus oryzae and the cellulase are prepared into the crop straw decomposition agent according to the scheme. The four fungi are not antagonistic and combined with the cellulase to have a synergistic interaction effect and the straws can be rapidly decomposed.

Description

Technical field: [0001] The invention belongs to the technical field of crop straw treatment, and in particular relates to a microbial decomposing agent for rapidly decomposing crop straws and a method for using the microbial decomposing agent. Background technique: [0002] Crop straw is one of the most abundant substances in the world. The output of crop straw in the world is about 2.941 billion tons, and the output of crop straw in my country is about 700 million tons per year, of which straw feed, straw energy, straw papermaking and building materials account for Two-thirds and one-third are discarded or incinerated. Crop straw is an important resource in the crop production system. It contains a variety of effective components that can be used. In addition to the vast majority of carbon, it also contains elements such as nitrogen, phosphorus, potassium, silicon, and calcium, as well as cellulose and semi-fibers. , lignin, protein, amino acid and other active ingredients...
