Biological agent for sterilization and insect prevention of nursery stock and preparation method of biological agent

Abstract

The invention relates to a biological agent for sterilization and insect prevent of nursery stock. The biological agent comprises pepper, cyrtomium fortune, radix bupleuri, pyrethrum, tobaccos, stemona japonica, radix platycodi, flos lonicerae, radix scutellariae and catechu. The components are put into water and decocted, liquid medicine with dregs filtered is added to water to be diluted and then the finished biological agent is obtained. When the biological agent is used, a static sprayer is used for spraying the whole nursery stock, after the biological agent is used for 2-3 days continuously, the prevention function is very good, the cure rate of diseases and the insect-killing rate are both high, and the biological agent is convenient to use, avoids drug residues, provides nutrition for the nursery stock and has certain sterilization and insect-killing functions on soil.

Description

technical field [0001] The invention belongs to the technical field of nursery stock planting, in particular to a seedling sterilizing insect-repelling biological preparation and a preparation method thereof. Background technique [0002] Seedlings are saplings with roots and stems. It is generally believed that all saplings cultivated in the nursery, regardless of their age, are collectively referred to as seedlings before they come out of the nursery. Wait. After the seedlings survive, they need careful care, such as: regular pruning to remove excessive germination, removal of branch growth points, short cuts of annual branches, thinning branches that are conducive to branch growth, pulling branches, etc. In addition to pruning, seedlings During the growth period, regular control of diseases and insect pests is also required. The diseases mainly include blight, anthracnose, damping-off, leaf spot, etc., and the pests mainly include red spiders and aphids. If it grows nor...

Problems solved by technology

After the seedlings survive, they need careful care, such as: regular pruning to remove excessive germination, removal of branch growth points, short cuts of annual branches, thinning branches that are conducive to branch growth, pulling branches, etc. In addition to pruning, seedlings During the growth period, regular control of diseases and insect pests is also required. The diseases mainly include blight, anthracnose, damping-off, leaf spot, etc., and the pests mainly include red spiders and aphids. Normal growth, if not treated, the seedlings will die, seriously affecting the income of growers

[0003] At present, growers mostly use seed disinfection, soil treatment and the use of chemical agents to prevent and control pests and diseases. However, various chemical agents are used in the above three treatment methods, which will cause damage to the seedlings and the soil itself. Long-term use many problems will remain
