Multi-functional liquid plant protection film agent

Abstract

The invention discloses a multi-functional liquid plant protection film agent. Natural raw materials such as fulvic acid, rice bran wax and mixed fat are emulsified to form thick water emulsion, and the emulsion belongs to green, low-carbon and environmentally-friendly products which are developed in a sustainable mode. The emulsion with water is sprayed on the full surfaces of plants to form a liquid film, before the liquid film is solidified, the film can paste pathogenic bacteria, spores of the bacteria, soft pests and ova of the pests and block pest air holes to enable the pests to be inactivated and stifle, the pathogenic bacteria, the spores of the bacteria, the soft pests and the ova of the pests are attached to the surfaces of the plants, after the film is naturally solidified, a solid protective micro film layer which can not be seen by naked eyes is formed on the surfaces of the plants, and seals and protects the plants, the film layer repels and isolates encroaching of multiple diseases and pests on crops and has the functions of conserving water, resisting drought, preventing freezing, preventing dry hot (cold) wind, preventing rain and preventing lodging, the use number of pesticides and the use amount of chemical fertilizer can be reduced, environment and food safety can be protected, meanwhile, labor intensity of farmers can be reduced, investment by the farmers can be reduced, and the aim that the production and income are greatly increased is achieved.

Description

technical field [0001] The invention belongs to the field of plant (crop) protection, and relates to a biological agent, in particular to a natural, multifunctional liquid plant protective film agent. To prevent insects, diseases, and stress, replace the widely practiced technology of covering apples and pears with plastic bags and paper bags during the growing season, greatly reduce the amount of pesticides and fertilizers, protect the environment, water sources and food safety, and save farmers' input and labor. Intensity, greatly improving the quality and output of agricultural products such as grain, cotton, oil, fruits and vegetables. Background technique [0002] my country has vigorously promoted the fruit tree bagging technology since 1981. At present, only 30 million mu of apples are planted in my country. According to the current bagging rate of 95%, the cost of bagging (plastic bags, paper bags) per mu is calculated at 2,000 yuan. The bagging of apples requires an...

[0002] my country has vigorously promoted the fruit tree bagging technology since 1981. At present, only 30 million mu of apples are planted in my country. According to the current bagging rate of 95%, the cost of bagging (plastic bags, paper bags) per mu is calculated at 2,000 yuan. The bagging of apples requires an investment of 30 million mu × 2000 yuan / mu × 95% = 57 billion yuan. As we all know, the bagging technology requires high investment, labor and labor intensity. Although the bagging technology improves the appearance of the fruit and reduces the Pesticide residues are removed, but the internal quality of the fruit is greatly reduced. Because the bagged fruit lives in the bag without sunlight for a long time, photosynthesis is seriously affected, which greatly reduces the sugar content and other nutrients of the bagged fruit. In addition, some new pests and diseases have been infested due to bagging. In addition, a large number of young laborers from rural areas have entered the city. As a result, the current bagging technology is no longer suitable for the national conditions in some places.
