Embodiment 3

[0080] Example 3 Effects of crop straw returning to the field on 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] Table 1 Effects of straw returning methods on soil

[0083] index parameter

[0084] 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 smal...

Abstract

The invention provides a composite biochemical agent. The composite biochemical agent comprises a straw decaying agent and a composting fermentation agent, wherein the composting fermentation agent is prepared from urea, lime and excrements of livestock according to a weight ratio of (4-5.5) to (7-10) to (10-15); the straw decaying agent is prepared from compound bacteria liquid and a carrier according to a weight ratio of 1 to 4. According to the composite biochemical agent disclose by the invention, the materials are completely composted in the straw treatment process, and lots of functional microbes and multiple metabolites such as plant hormones, antibiotics and the like are produced, so that growth and development of the crops are stimulated, the soil nutrient is improved, the soil structure is improved, the chemical fertilizer utilization ratio is improved, the operation is easy and convenient, and the production is facilitated.

Description

technical field [0001] The invention belongs to the technical field of comprehensive application of straw resource utilization, and in particular relates to a compound biochemical preparation and its application in straw returning to the field. Background technique [0002] Modern agriculture has a large area of ​​arable land, and agricultural production has caused a large surplus of straw. The open burning of straw has caused waste of resources and proven air pollution. However, because it cannot be fully utilized, the phenomenon of burning has been repeatedly banned, and it has become the focus of the whole society. Straw returning to the field is a method of applying straw (wheat straw, corn straw, rice straw, etc.) that are not suitable for direct feed into the soil directly or piled up and decomposed. The process of agricultural production is also a process of energy conversion. During the growth process, crops need to constantly consume energy, and also need to consta...
