Protecting agent capable of preventing nursery stock from being gnawed and eaten by animals

Abstract

The invention relates to a protecting agent of seedlings for preventing animals from eating, which is prepared by a repellent and a compound adhesive, wherein, the repellent consists of tetramethylthiuram disulfide, minium (a traditional Chinese medicine), sulphur powder and a water retention agent. The protecting agent can also effectively repel rabbits, large animals such as wild animals of donkeys, mules, sheep, wild boars, roe deer and the like, based on multiple functions of repelling rats and birds, water retention and drought resistance; by continuous tests for 8 years, the invention is proved that the shortest retention period of the residue of drug effect is 2 years and the retention period is improved 6 to 10 times than the residual period of the existing similar protecting agent; the perfectness ratio of forest is improved to more than 91 percent to 99 percent by comparison and the retention of the young forest is improved by 300 percent by comparison. The protecting agent has no harm to humans and animals and no pollution, and does not kill various organisms in the forest so as to cause the damage of biological chain. The protecting agent is coated on the trunk to forma layer of drug membrane, thus effectively solving hydrolysis as well as damage and degradation of various microorganisms, and keeping the molecular level of the drug not to change; and the source ofdrug materials is easy to obtain.

Description

technical field [0001] The invention relates to a seedling protective agent which has the function of repelling and preventing various animals such as rats, rabbits, sheep, donkeys and birds from gnawing. Background technique [0002] In recent years, with the rapid development of forestry, the area of ​​new afforestation has increased significantly in various places. In the western and northern regions of my country, where the ecology is relatively fragile, and the dry heat and drought caused by El Niño weather have caused increasingly serious damage to forest rodents. There are many reports on the species, distribution and fauna of rodents in forest areas. There are more than 60 types of rodents that can cause great harm in various zoogeographic regions in my country. The tree species that rodents harm are almost all tree species in artificial forests. The harm of rodents to forestry is mainly manifested in the stealing of live seeds, gnawing on seedlings or young tree bar...
