Insect control method for seedling cultivation in cedrela sinensis greenhouse container

Abstract

The invention discloses an insect control method for seedling cultivation in a cedrela sinensis greenhouse container. The method comprises the following steps of: performing broad-spectrum and low-toxicity sterilization, and insecticidal and ovicidal spray disinfection on a cedrela sinensis greenhouse container seedling cultivation substrate; uniformly mixing; covering and sealing the cedrela sinensis greenhouse container seedling cultivation substrate with a thin film; bubbling the substrate for 12 days; and transplanting cultured cedrela sinensis seedlings into the substrate, wherein the whole cedrela sinensis seedling culturing process is performed in a greenhouse of which the ground is hardened. The key of the method lies in the seedling cultivation matrix and the sterilization treatment. After being subjected to broad-spectrum and low-toxicity sterilization, and insecticidal and ovicidal spray disinfection, the seedling cultivation substrate is sealed by the thin film to bubble for 12 days so that the disease source and the insect source in the seedling cultivation substrate are killed. The whole cedrela sinensis seedling culturing process is performed in the greenhouse of which the ground is hardened, wherein greenhouse cultivation contributes to the prevention of dampingoff, the hardened ground contributes to the prevention of insects, and disease and insect rate of cedrela sinensis nursery stocks is reduced to 0.7 percent. Therefore, the insect control method has very obvious control effect and can be widely applied to massive cultivation of cedrela sinensis seedlings.

Description

technical field [0001] The invention relates to the technical field of Chinese toon seedling cultivation, in particular to a method for preventing and treating diseases and insect pests of Chinese toon growing seedlings in greenhouse containers. Background technique [0002] Toona sinensis is a tree of the genus Toona sinensis in the family Meliaceae. It is a unique and precious fast-growing timber tree species in my country. It has high nutritional value, edible value, medicinal value and timber value. As the vegetable cultivation of Toona sinensis has become the preferred project for farmers in some areas of my country to get rid of poverty and become rich, the rapid breeding of a large number of Toona sinensis seedlings has become an urgent need. Therefore, the research on the technology of Toona sinensis seedlings has made rapid progress. However, there are still some problems worthy of in-depth discussion. In Chinese toon greenhouse container seedling cultivation, seedl...
