Problems solved by technology

[0002] The existing soil improvement methods are relatively simple, often only improving one target, without forming a unified technical system; the traditional planting mode still relies on a large amount of quick-acting fertilizers such as compound fertilizers and nitrogen, phosphorus and potassium fertilizers, which are applied to the soil every year Only a small part of the fertilizer is absorbed and utilized by crops, and the rest of the fertilizer is either leached with rainwater or fixed by soil aggregates. If things go on like this, soil continuous cropping problems, heavy cropping problems, hardening problems, and salinization problems will all appear, seriously changing The physical and chemical properties of the soil are severely degraded, and the growth of crops is inhibited to varying degrees, resulting in a decline in the resistance of the crops themselves, making it difficult to resist the invasion of diseases and insect pests, resulting in reduced crop yields and reduced economic benefits for growers.
[0003] According to statistics, more than 80% of the soil in our country is not short of nutrients, and the measured values ​​of soil nutrients are all on the high side. However, the nutrients in the soil are often difficult to be absorbed and utilized by crops. As the temperature rises, nutrients are absorbed by soil aggregates, causing a vicious cycle in saline-alkali land and destroying the ecosystem

Embodiment 1

[0053] A strawberry planting demonstration test was carried out on the "quaternary" soil improvement and restoration method of the present invention.

[0054] The "quaternary" soil improvement and restoration method includes deep soil improvement treatment and shallow soil restoration treatment.

[0055] The operation of the deep soil improvement treatment includes: uniformly mixing 1000Kg of crushed crop straw, 5000Kg of livestock and poultry manure, 150Kg of soil conditioner, 100Kg of multi-mineral fertilizer, and 1Kg of agricultural and forestry water-retaining agent according to the dosage per mu to form a mixed material , spread it on the surface of the treatment shed, and then spray or spread 8Kg of disease-resistant and probiotic compound microbial agent per mu; then use a rotary tiller to deeply plow the soil layer, the plowing depth is 20-30cm, and water after plowing Enough water, and then cover the soil surface with a transparent plastic film, and carry out 15-20 da...

Embodiment 2

[0078] In this example, the same "quaternary" soil improvement and restoration method as in Example 1 was used to carry out a tomato cultivation experiment. The effects of the quaternary soil improvement and restoration treatment and the conventional treatment were compared, wherein the conventional treatment was the same as in Example 1.

[0079] Table 5 Determination of nutrient content in tomato soil

[0080]

[0081] Through the quaternary soil improvement and restoration method, the mineral nutrients in the soil have been fully improved. Compared with the conventional treatment, the total nitrogen content increased by 50%, indicating that the nitrogen-fixing effect of nitrogen-fixing bacteria was obvious; the content of available phosphorus and available potassium increased by 53% and 38%, respectively, indicating that the four-element soil improvement and restoration can release the fixed phosphorus in the soil Potassium nutrients. Figure 4 It shows the comparison ...

Abstract

The invention belongs to the technical field of agriculture, and particularly relates to a method for soil improvement and remediation by using a 'quaternary' method, a compound microbial agent used in the method, and application of the compound microbial agent in soil improvement and remediation. The 'quaternary' soil improvement and remediation method starts from organic matter improvement, mineral substance improvement, biodegradation and disease resistance and growth promotion, and comprehensive improvement and remediation are carried out on soil in four aspects of soil physical structure, chemical nutrients, biological activity and soil-borne diseases through deep soil improvement and shallow soil remediation. The activity of soil carbon-nitrogen cycle related enzymes can be remarkably improved, the soil microbial population structure is optimized, the soil microbial function is improved, plant residues in soil are driven to be fermented through the interaction of disease-resistant probiotic microorganisms, beneficial microorganisms become main force of soil activity, the soil structure is improved, land is fully utilized, and the method is of great significance in sustainable development of agriculture, improvement of the income level of farmers, improvement of life of people, protection of ecological environment and the like.

Description

technical field [0001] The invention belongs to the field of agricultural technology, and in particular relates to a method for soil improvement and repair using the "quaternary" method, a soil improver used in the method, a disease-resistant probiotic compound microbial agent, and the soil improver or Application of disease-resistant and probiotic compound microbial agents in soil improvement and restoration. Background technique [0002] The existing soil improvement methods are relatively simple, often only improving one target, without forming a unified technical system; the traditional planting mode still relies on a large amount of quick-acting fertilizers such as compound fertilizers and nitrogen, phosphorus and potassium fertilizers, which are applied to the soil every year Only a small part of the fertilizer is absorbed and utilized by crops, and the rest of the fertilizer is either leached with rainwater or fixed by soil aggregates.
