Problems solved by technology

[0003] However, the high-fat film in the prior art (for example, the patent No. is the high-grade fatty alcohol lipid film of the preparation method of CN201610959583.X) is not outstanding enough in improving the performance of crop stress resistance and crop yield, and its disease prevention and control effect is not bad. However, it is not effective in controlling pests

Abstract

The invention provides a plant protective film agent using tea cake powder as a surfactant. The plant protective film agent comprises the following components: tea cake powder, higher aliphatic alcohol, an emulsifier, an auxiliary emulsifier, a thickener and water. With the adoption of the plant protective film agent using tea cake powder as the surfactant and a preparation method provided by theinvention, the following technical effects can be achieved: the film forming mechanism is strengthened, the film structure is more stable, the uniformity is better, the spreading property after wetting is strong, and the light transmission, the air permeability and the water retention are excellent and obviously enhanced.

Description

technical field [0001] The invention relates to a plant protective film agent, more specifically, relates to a plant protective film agent using tea dry powder as a surfactant, a preparation method and application thereof. Background technique [0002] Higher fatty alcohol lipid film (referred to as high lipid film), using surfactant Nongru 0203B as emulsifier, starch, washing powder, etc. as emulsifying aids, adding water to emulsify higher fatty alcohol into water emulsion under certain conditions. Spray on the leaves of plants to form a film composed of higher fatty alcohols. Due to the existence of this film, it can achieve the effects of preventing and controlling diseases and insect pests, moisturizing and drought resistance, and improving crop stress resistance and yield through physical methods. [0003] However, the high-fat film in the prior art (for example, the patent No. is the high-grade fatty alcohol lipid film of the preparation method of CN201610959583.X) is...
