Embodiment 1

[0012] Embodiment 1, use VIF film to utilize methyl bromide to carry out soil disinfection

[0013] The used methyl bromide is 98% methyl bromide+2% stabilizer, stored in a high-pressure tank, purchased from China Lianyungang Dead Sea Bromide Chemical Co., Ltd., the specific method is as follows:

[0014] 1) Plow the soil to a depth of 25-30cm, and then level the soil to keep the soil loose.

[0015] 2) Lay out plastic pipes, place a soft plastic pipe 6cm wide and several meters long every 2m (this pipe has a discharge hole every 15cm), and then insert a smaller plastic pipe into the plastic pipe belt.

[0016] 3) Cover the VIF film, and use soil to compact the plastic film around to prevent the leakage of methyl bromide.

[0017] 4) Methyl bromide discharge: When the temperature of the water bath reaches about 80°C, open the air compressor and the valve of the methyl bromide steel cylinder, and connect with the smaller plastic pipe in step 2) to discharge methyl bromide. 37...

Embodiment 2

[0019] Embodiment 2, use VIF film to utilize metabam to carry out soil disinfection

[0020] The used metabam is produced by Shenyang Pesticide Factory, which is a 37% water solution. The specific method is as follows:

[0021] 1) Plow the soil to a depth of 25-30cm, then level the soil, and then install a drip irrigation system with a distance between dripper rows of 0.3m, a distance between dripper holes of 0.3cm, and a maximum flow rate of 1.5L / h.

[0022] 2) Cover with VIF film, and then use soil to compress the plastic film around tightly to prevent pesticide leakage.

[0023] 4) Applying pesticides to keep the steady water flow rate of the drip irrigation system. At this time, add Metabam gradually into a plastic container and cover it to prevent volatilization. The application dosage is 75g (37% water formulation) / m 2 , so that the liquid medicine is evenly applied to the soil with the drip irrigation system.

[0024] 5) Remove the film four weeks after spraying, and ...

Abstract

The invention relates to a preparation method of drug soil. According to the method, to-be-disinfected soil is covered with VIF film, then 37% of an aqueous metham-sodium solution of 60-80g/m<2> soilis applied in the film in a drip irrigation manner to disinfect the soil, the line spacing of droppers adopted by the drip irrigation is 0.3m, the hole pitch of the droppers is 0.3cm, and the maximumflow rate is 1.5 L/h. The preparation method of the drug soil has the advantages that the method is simple, practical, safe and effective, not only can effectively control pests and other soil-borne diseases in the soil and improve the drug application efficiency, but also reduces the environmental pollution caused by the large-dose use of pesticides, thereby having high promotion and practicalityvalue.

Description

technical field [0001] The invention relates to a preparation method of medicinal soil. Background technique [0002] my country's vegetable protected area has developed rapidly, and has reached 4 million hectares at present. However, because its special production conditions provide a suitable environment for pests in the soil, the economic loss caused is generally 20%-40%, which seriously restricts the production of vegetables in protected areas and the construction of urban "vegetable baskets" in my country. Contents of the invention [0003] The purpose of the invention is to provide a method for preparing medicinal soil. [0004] The preparation method of the medicinal soil provided by the present invention is to cover the soil to be sterilized with a VIF film, and then apply 35-40g / m to the soil in the film 2 Soil methyl bromide agent, or 60-80g / m 2 Soil 37% water agent Metamac for soil disinfection. [0005] Among them, methyl bromide can be discharged into the ...
