Abstract

The invention discloses a multifunctional antitranspirant and a preparation method thereof. The multifunctional antitranspirant comprises 10-15 g / L of chitosan, 2-4 g / L of calcium chloride, 2-4 g / L ofdextran, 2-4 g / L of magnesium sulfate, 3-5 g / L of zinc sulfate, 10-20 g / L of Metarhizium anisopliae and 0.01-0.05 g / L of Tween-20. The above components are mixed in different proportions to prepare an aqua, and the aqua is sprayed on leaf surfaces to reduce transpiration, improve the water utilization capability of crops and provide nutrients for the growth of the plants. The multifunctional antitranspirant is developed based on the stomatal immune mechanism, and has the advantages of low preparation cost, wide applicability, less residual toxicity, obvious water saving effect, good anti-disease effect, broad market space and broad application prospect.

Description

technical field [0001] The invention relates to the technical field of crop drought resistance and water saving, in particular to a multifunctional anti-transpiration agent and a preparation method thereof. Background technique [0002] The efficiency of my country's agricultural water use is low, and there is a phenomenon of water shortage and waste coexisting. How to improve water use efficiency has become an important issue faced by scientists. Water scarcity is a major constraint on global economic and social development. Most of the water absorbed by plants is lost to the atmosphere through transpiration. How to control the movement of stomata and reduce the extravagant transpiration water of plants is an important research direction for agricultural water conservation. Anti-transpiration agent is a general term for a class of substances that act on the surface of plants to regulate plant transpiration and improve plant water use efficiency. Anti-transpiration agents...
