Problems solved by technology

The spraying method used in the above control method 1 can only play a certain inhibitory effect on the fungi on the soil surface, and is easy to volatilize and decompose, and has little effect on the germs and pests under the surface soil layer; the method 2 uses a large dosage, high cost, and is environmentally safe. Poor resistance and serious residue; method 3 has a slightly longer duration, but after several times of watering, the efficacy of the drug will be reduced after being dispersed under the action of water flow, and it cannot protect the roots of vegetables for a long time; method 4 cleans up the shed and Pulling out the diseased plants can play a certain preventive role, but it is ineffective against the bacteria accumulated in the soil; trapping adults can only reduce the damage of root pests; 5. The disinfection method used has serious pesticide residues, or the effect is not good, or the equipment price is high. Application complexity and other issues

[0022] A kind of method that embodiment 1 medicine separation film prevents and treats sweet pepper root rot, comprises the following steps:

[0023] (1) Soak a rectangular isolation film with a length of 20 cm and a height of 10 cm in a medicinal solution diluted 800 times with 72% gram for 10 minutes, take it out and place it in a cool and dark place to dry.

[0024] (2) When planting sweet pepper seedlings, mix the matrix with a liquid medicine diluted 800 times with 72% gram.

[0025] (3) Surround the soaked and dried drug isolation film into a cylinder with a diameter of 6 cm and a height of 10 cm.

[0026] (4) Put the seedlings together with the original soil in the paper tube, and the middle and upper part of the roots of the seedlings are even with the bottom edge of the bamboo.

[0027] (5) Plant the seedlings wrapped in the medicine film in the soil, and fill the remaining space with the medicine soil.

[0028] (6) Water the planting water.

Embodiment 2

[0029] Embodiment 2 A method for preventing and treating vegetable root rot with a drug barrier film, comprising the following steps:

[0030] (1) Cut the plastic film (0.08mm-0.12mm) into a rectangle with a length of 20cm and a height of 10cm, soak it in a liquid medicine diluted 300 times with 72% gram for 10min, take it out and place it in a cool and dark place to dry.

[0031] (2) When vegetable seedlings are planted, mix the substrate with a liquid medicine diluted 800 times with 72% gram.

[0032] (3) Surround the plastic film into a cylinder with a diameter of 6 cm and a height of 10 cm.

[0033] (4) Put the seedlings together with the original soil in the paper tube, and the middle and upper part of the roots of the seedlings are even with the bottom edge of the tube.

Abstract

A method for preventing and eliminating the diseases and pests of vegetable root by use of the isolating chemical film includes such steps as rolling the isolating chemical film to become a cylinder, filling the agricultural chemical contained matrix or disinfecting soil in it, irrigating and planting vegetable in it.

Description

Technical field: [0001] The invention relates to a method for preventing and controlling plant diseases, in particular to a method for preventing and controlling plant soil-borne fungal diseases. Background technique [0002] In recent years, my country's facility vegetable production, as a pillar industry of rural regional economic development, has made great progress. Due to the difficulty of vegetable rotation in facilities, continuous cropping in four seasons during production leads to the accumulation of pathogenic bacteria in the soil and continuous occurrence of pests. Root pathogens can survive in the soil or on diseased residues for a long time, and spread through water flow or soil, causing serious damage to the roots of facility vegetables or causing systemic disease; underground pests seriously endanger the growth of vegetable roots, especially at the seedling stage. Cause lack of seedlings and broken ridges, so that the plants grow slowly, dwarf or even die. P...
