Embodiment 1

[0031] An organic prevention and control method for plant strawberry pests and diseases, comprising the steps of:

[0032] 1. Organic prevention and control of plant diseases and insect pests of strawberry seedlings:

[0033] (1) Seedbed disinfection before sowing: use ozone fumigation method or horseradish aqueous emulsion to sterilize the soil in the seedbed. For plant residues in the soil, adjust the relative humidity of the soil to 75-90% or more, and the soil temperature is not higher than 60°C. The height of the ridge is 40cm-50cm, the width of the ridge is 50cm-60cm, the distance between the ridges is 100cm-120cm, and the surroundings are made into embankments. , the interior is interconnected and ozone pipes are laid, the soil surface is covered with plastic film as a whole, the surrounding area is compacted, ozone is continuously introduced, and the ozone generator is adjusted so that the output speed of ozone is 45-50g / h, and the continuous treatment is 10-20 hours, ...

Embodiment 2

[0045] 1. Effect of seedbed soil disinfection on strawberry seedling rate

[0046] Control seedbed: 200m 2 Seedbed soil is not disinfected;

[0047] The first treatment seedbed: 200m 2 The seedbed is disinfected with ozone fumigation: dig the soil 25cm deep and remove the plant residues in the soil, adjust the relative humidity of the soil to 75-90%, and the soil temperature is not higher than 25°C. Make ridges and lay ozone pipes. Cover the whole with plastic film, compact the surrounding area, continuously inject ozone, adjust the ozone generator so that the output rate of ozone is 45-50g / h, treat continuously for 10 hours, and remove the film to plant after 2 days.

[0048] The second treatment seedbed: 200m 2 The seedbed is disinfected with 20% horseradish water emulsion: dig the soil 25cm deep and remove the plant residues in the soil, spray water to adjust the relative humidity of the soil to 45-55%; after making ridges and laying drip irrigation equipment, the soil s...

Abstract

The invention relates to an organic prevention and control method for facility strawberry pest and disease damage. The method has the advantages that the method is simple, convenient and feasible, safety and environment protection are realized, the pollution is avoided, the organic production of strawberries can be realized, the quality of the strawberries is fundamentally improved, and the yield of the strawberries is improved. The method provided by the invention comprises the following steps of 1, organic prevention and control for pest and disease damage of facility strawberry seedlings: seedling bed sterilization before seeding; biological control of pest and disease damage during seedling period; and seedling root dipping treatment; 2, organic prevention and control on pest and disease damage in a house before the facility strawberry fixed planting: house physical prevention and control: in-house sterilization; and house soil sterilization; and 3, organic prevention and control on pest and disease damage after the facility strawberry fixed planting: pest killing through hanging and installing pest trap plate in the house after the facility strawberry seedling fixed planting, and pest and disease damage prevention through sulphur fumigation via installing a sulfurator; and biological prevention and control on pest and disease damage in the strawberry growth period.

Description

technical field [0001] The invention relates to a method for preventing and controlling plant diseases and insect pests, in particular to an organic prevention and control method for facility strawberry diseases and insect pests. Background technique [0002] According to the investigation and identification, the main strawberry diseases and insect pests include powdery mildew, root rot, anthracnose, gray mold, leaf spot, spider mite, two-spotted spider mite, flower thrips, aphids, etc. Among them: powdery mildew, root rot, spider mite, two-spotted spider mite, and flower thistle are the most serious damage. The rate of powdery mildew disease is close to 100%, the rate of diseased plants is often over 60%, and the production loss is 10% to 30%. The general incidence of rot is 5% to 15%, and in severe cases, it can reach more than 50% or even completely destroy; red spider mite, two-spotted spider mite, and flower thrips are common, and the loss is estimated to be 10% to 20%....
