Abstract

The invention discloses a method for professionally repairing hardened soil, and belongs to the technical field of soil environment repair. The method comprises the following steps of firstly, deeply ploughing and rotary tillage by using a ploughing machine and a rotary cultivator on hardened soil, applying the soil after rotary tillage into a biofertilizer capable of improving soil hardening and increasing porosity and porosity, wherein the biofertilizer consists of the following basic fertilizers and target microbial flora: the garden withered branch and fallen leaf rotten fertilizer, Jingyang streptomycete, photosynthetic bacteria group, aspergillus oryzae, bacillus subtilis, bacillus licheniformis, bacillus megaterium and other microorganisms, wherein each gram of the biofertilizer contains about 5.2-18 hundred million of the various bacteria groups. The repairing method is simple and easy to implement, convenient to operate and low in repairing cost, can obviously improve the symptoms of soil hardening, can greatly enhance the buffering capacity of soil, improve the ventilation and water permeability of the soil, promote the water retention and moisture preservation of the soil, enhance the drought resistance, cold resistance and waterlogging resistance of plants, and meanwhile, the microorganism living body in the biological fertilizer can also strengthen the leaf protecting film, resist pathogen infection and improve the disease resistance and insect resistance of the plants, and has obvious repairing effect and long time-effect.

Description

Method for repairing hardened soil specially

Technical Field

The invention relates to a method for restoring plate-bound soil, and belongs to the technical field of soil environment restoration.

Background

Soil is an agricultural resource that can be recycled. At present, as people use chemical fertilizers and pesticides to the maximum extent, the utilization rate of the chemical fertilizers is low, soil salinity is gathered, soil is hardened, soil fertility is reduced, and the like, particularly microorganisms in soil are reduced greatly, and the soil is in continuous deterioration and deterioration, so that the great development of agriculture is restricted. The problem of soil hardening is a great problem in agriculture in various countries, and soil hardening generally shows that the soil is poor in organic matter, poor in structure and poor in granular structure, the structure is easy to damage during irrigation, soil grains are dispersed, the soil is hardened after drying, soil hardening can cause soil impoverishment, air permeability and water permeability are poor, nutrient absorption is difficult, and plant growth is further seriously influenced.

At present, the main measures for improving the soil hardening problem are to reduce the using amount of chemical fertilizers, increase the application of organic fertilizers and increase the use of soil conditioners, but the cost is usually too high, the effect on the soil hardened seriously is not obvious, and the high yield of crops cannot be ensured.

Disclosure of Invention

The invention aims to solve the technical problem of providing a biological method which has quick response and long time effect and can obviously repair hardened soil.

In order to solve the technical problems, the invention adopts the following technical scheme: a method specially used for repairing hardened soil is completed by combining farming measures with the use of biological fertilizers. The biological fertilizer consists of a base fertilizer and target microbial floras, wherein the base fertilizer is garden dead branch fallen leaves rotten fertilizer, the share of the garden dead branch fallen leaves rotten fertilizer is 78-95, the target microbes are streptomyces jingyangensis, photosynthetic bacteria, aspergillus oryzae, bacillus subtilis, bacillus licheniformis, bacillus megaterium and the like, and the share of all the floras is 5-22.

The invention adopts a specific technical scheme

A method for repairing hardened soil in a professional way is characterized in that a farming measure is combined with a biological fertilizer for repairing the hardened soil. The main operation is as follows: deep ploughing and rotary tillage are carried out on hardened soil in a hardened soil area by using a ploughing machine and a rotary cultivator, and then biofertilizer is applied to the soil after deep ploughing and rotary tillage according to the proportion (3% -25%), wherein the biofertilizer is composed of base fertilizer and target microbial flora, the base fertilizer is garden dead branch fallen leaf rotten fertilizer, the share of the base fertilizer is 78-95, the target microbial flora is streptomyces jingyang, photosynthetic flora, aspergillus oryzae, bacillus subtilis, bacillus licheniformis, bacillus megaterium and the like, each gram of the biofertilizer contains about 5.2-18 hundred million of the various floras, and the share of all the floras is 5-22.

The beneficial effects obtained by the invention are as follows: the farming measures combining rotary tillage and deep ploughing can quickly improve the hardened symptoms of soil, meanwhile, the organic fertilizer decomposed by dead branches and fallen leaves can increase the content of organic matters in soil, promote the formation of soil granular structures, and microorganisms such as streptomyces jingyang, photosynthetic bacteria group, aspergillus oryzae, bacillus subtilis, bacillus licheniformis, bacillus megaterium and the like can generate a large amount of plant endogenous enzymes in the metabolic process, so that the soil structure can be obviously improved, the absorption rate of crops on nutrient elements such as nitrogen, phosphorus, potassium and the like can be improved, meanwhile, the decomposition of organic substances can be accelerated, and quick-acting nutrients can be manufactured for the crops and power can be provided.

Detailed Description

In order that the technical means, inventiveness and novelty of the present invention may be better understood and appreciated, they are further described below in connection with the specific embodiments.

Examples

1000m in a farmland with serious soil hardening²The agricultural cultivator is used for deeply ploughing twice with the depth of about 35cm, and then the rotary cultivator is used for rotary tillage twice to break the surface layer bulk soil. Meanwhile, collecting fallen leaves of green plants in main parks in autumn and dry branches pruned in winter, uniformly gathering the fallen leaves and the dry branches on a hollow flat ground, mixing the fallen leaves and the dry branches, piling the mixture into a high pile, compacting the high pile by using a shovel, piling the high pile for 3 months to 9 months until no white air is emitted from the interior of the high pile, finishing the decomposition, and crushing the high pile into the powder with the diameter of 1-3cm by using a crusher for later use. Purchasing or culturing microorganisms such as Jingyang streptomycete, photosynthetic bacteria group, aspergillus oryzae, bacillus subtilis, bacillus licheniformis and bacillus megaterium by self, and mixing different bacteria groups. And finally, pouring 15kg of mixed flora into 185kg of crushed dead branches and fallen leaves, and uniformly mixing to obtain the biological fertilizer. The prepared 13-square biofertilizer is applied to a hardened soil site according to the volume ratio of 5%, and rotary tillage is performed twice by using a rotary cultivator after the biofertilizer is applied, so that the biofertilizer and the soil are uniformly mixed, and the hardened soil restoration effect is better.
