Problems solved by technology

[0003] Now people usually use chemical agents to kill various bacteria, viruses and underground pests in the soil of greenhouses, such as highly toxic pesticides such as carbofuran, phorate, Shennongdan (aldicarb) and abamectin, chitin, etc. , bromoethane and other methods to prevent and control pests and diseases, and some use calcium cyanamide for soil disinfection treatment. However, because bacteria, viruses, and underground pests in the soil can move in the soil, they can completely kill all kinds of pests in the soil. A variety of bacteria, viruses and underground pests have brought difficulties, and all chemical agents to treat the soil will bring pesticide residues in the soil, causing safety hazards

Embodiment 1

[0021] A paddy soil disinfection method, it comprises the following steps:

[0022] Step 1: When planting rice, the soil is placed in a waterproof membrane or a matrix groove, and then rice is planted on the soil in the waterproof membrane or matrix groove;

[0023] Step 2: After the rice is harvested, use a high-pressure water gun to spray the soil for planting rice from the waterproof membrane or matrix groove to make the soil soft;

[0024] Step 3: Physically disinfect the sprayed soil;

[0025] Step 4: Add the soil after physical disinfection to the rice soil and seal it with reducing agent for 15-30 days.

[0026] In step 4, stack the soil layer by layer, and sprinkle the reducing agent for rice soil on the surface of each layer of soil. After stacking, cover it with a plastic film and seal it. The thickness ratio of soil and reducing agent for rice soil is 1:1.

[0027] The reducing agent for the paddy soil is composed of sawdust, soybean meal, pond bottom mud, rice br...

Embodiment 2

[0033] A paddy soil disinfection method, it comprises the following steps:

[0034] Step 1: When planting rice, the soil is placed in a waterproof membrane or a matrix groove, and then rice is planted on the soil in the waterproof membrane or matrix groove;

[0035] Step 2: After the rice is harvested, use a high-pressure water gun to spray the soil for planting rice from the waterproof membrane or matrix groove to make the soil soft;

[0036] Step 3: Physically disinfect the sprayed soil;

[0037] Step 4: Add the soil after physical disinfection to the rice soil and seal it with reducing agent for 15-30 days.

[0038] In step 4, stack the soil layer by layer, and sprinkle the reducing agent for paddy soil on the surface of each layer of soil. After stacking, cover it with plastic film and seal it. The thickness ratio of soil and reducing agent for paddy soil is 2:1.

[0039] The reducing agent for rice soil is composed of sawdust, soybean meal, pond bottom mud, rice bran, m...

Embodiment 3

[0045] A paddy soil disinfection method, it comprises the following steps:

[0046] Step 1: When planting rice, the soil is placed in a waterproof membrane or a matrix groove, and then rice is planted on the soil in the waterproof membrane or matrix groove;

[0047] Step 2: After the rice is harvested, use a high-pressure water gun to spray the soil for planting rice from the waterproof membrane or matrix groove to make the soil soft;

[0048] Step 3: Physically disinfect the sprayed soil;

[0049] Step 4: Add the soil after physical disinfection to the rice soil and seal it with reducing agent for 15-30 days.

[0050] In step 4, stack the soil layer by layer, and sprinkle the reducing agent for paddy soil on the surface of each layer of soil. After stacking, cover it with a plastic film and seal it. The thickness ratio of the soil and the reducing agent for paddy soil is 6:1.

Abstract

The invention relates to the technical field of agricultural planting, in particular to a rice soil sterilizing method. The method is characterized in that rice planting soil is raised by a high-pressure water gun so as to loosen the soil and keep humidity, the raised soil is subjected to physical sterilizing to kill various bacteria, viruses and underground pests in the soil, and a rice soil reducing agent is added into the sterilized soil to seal the soil for 15-30 days so as to further sterilize and remedy the soil. The rice soil sterilizing method has the advantages that sterilizing and fertilizing are achieved at the same time, and the method is safe, nontoxic, thorough in sterilizing and capable of effectively remedying the soil, shortening rice rotation cycle and increasing rice yield.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a rice soil disinfection method. Background technique [0002] At present, the number of greenhouses in our country is increasing day by day, and greenhouse production is an important method of modern agricultural production. However, under the special conditions of protected cultivation, the growth and reproduction of soil-borne diseases and pathogenic bacteria are accelerated, the accumulation of pathogenic bacteria in the soil increases, and the prevalence of various crop bacteria, fungi, viruses and root-knot nematodes. If this kind of disease is not controlled in time, it will cause severe production reduction or even complete failure of commercial crops. Disinfecting the soil can better control the spread of soil-borne diseases and improve the quality and value of agricultural products. [0003] Now people usually use chemical agents to kill various bacteria...
