Embodiment 1

[0026] 1) Soil preparation: On a sunny day in early spring, plow the planting plot to a depth of about 30cm. It is required to rake deep and finely to level the land and pick out weeds, stones and other sundries. After being exposed to the sun for 10 days on a sunny day, the furrow width is 1500mm, the width of the drainage ditch is 200-250mm, and the depth of the drainage ditch is 200mm;

[0027] 2) Lime treatment: Take 70kg of quicklime and crush it, pass through a 30-mesh sieve, mix the quicklime powder and herbicide evenly, the ratio of lime to herbicide is: add 2g of herbicide for every 10kg of quicklime;

[0028] 3) Liming: Spread the lime mixture evenly into the soil of the plow layer, mix the quicklime with the soil at a depth of 5 cm on the surface, and spray it on the furrow surface with a small amount of water. It is advisable to keep the surface soil moist;

[0029] 4) Covering with black film: Cover the furrow surface with a black film with a width of 2 meters and...

[0032] 1) Soil preparation: On a sunny day in early spring, plow the planting plot to a depth of about 30cm. It is required to rake deep and finely to level the land and pick out weeds, stones and other sundries. After being exposed to the sun for 8 days on a sunny day, the furrow width is 1500mm, the width of the drainage ditch is 200-250mm, and the depth of the drainage ditch is 200mm;

[0033] 2) Lime treatment: Take 50kg of quicklime and crush it, pass through a 30-mesh sieve, mix the quicklime powder and herbicide evenly, the ratio of lime to herbicide is: add 10g of herbicide for every 10kg of quicklime;

[0034] 3) Liming: Spread the lime mixture evenly into the soil of the plow layer, mix the quicklime with the soil 10 cm deep on the surface, and spray it on the furrow surface with a small amount of water. It is advisable that the surface soil is moist;

[0035] 4) Covering with black film: Cover the furrow surface with a black film with a width of 2 meters and a thick...

Abstract

The invention provides a picria felterrae planting pest control method. By taking the advantages of sterilization of quicklime in heat emission and the characteristics of heat and moisture preservation of black films, sterilization and insecticide treatment of land parcels where picria felterrae is planted can be realized through the method, so that occurrence rate of pest and disease damages can be reduced with no use of pesticide. Picria felterrae obtained by means of the natural pollution-free picria felterrae planting pest control method is free of pesticide residues, and crude medicine which is higher in quality and safer can be provided.

Description

technical field [0001] The invention relates to the field of plant disease and insect pest control, in particular to a method for planting plant diseases and insect pests of Sophora scrophulariae. Background technique [0002] In order to reduce or prevent pathogenic microorganisms and pests from harming crops or humans and animals, some means are artificially adopted, which is called pest control. [0003] Pest control can be divided into chemical control using chemical substances such as fungicides or insecticides; physical control using physical energy such as light or rays, or building barriers; farming control that changes crop varieties, cultivation time or environment to reduce damage; Biological control based on the use of natural enemies. After the Second World War, due to the development of pesticides based on organic synthetic agents, it has been relatively easy to kill pests and diseases. Pests cause harm. At the same time, because these pesticides directly har...
