Multifunctional antitranspirant and preparation method thereof

Abstract

The invention discloses a multifunctional antitranspirant. The contents and the weight percentage of each content thereof are as follows: hydroxyethyl methyl cellulose: 10 to 60 percent; biochemistry fulvic acid power: 5 to 25 percent; organic rare earths: 1 to 10 percent; sodium hexametahposphate: 0 to 5 percent; dodecyl sodium sulfate 0 to 4 percent; monopotassium phosphate: 3 to 15 percent; organic trace element: 1 to 14 percent; polyacrylate sodium: 0 to 10 percent; uniconazole: 0 to 2 percent; and a- rhodofix: 0 to 2 percent. The organic rare earth is obtained from carrying out chelation reaction to azotic acid rare earth with chelating agent; the organic trace element is a compound organic trace element which obtained from adding deionized water and chelating agent into one or a plurality of combinations of CuSO4, ZnSO4, FeSO4 and MnSO4 to carry out chelation reaction. The invention has the functions of drought control, wind proof, transpiration inhibition, plant growth adjustment and fortification, can raise the survival rate and preservation rate of plants, improve the survival state of plants and furtherly raise the ability to resist degeneration, resist disease, control drought and resist cold, thereby reaching the purpose of water saving, seed preserving and production and income increasing.

Description

technical field [0001] The invention belongs to the technical field of ecology (agriculture and forestry), and in particular relates to a multifunctional anti-transpiration agent and a preparation method thereof. Background technique [0002] With global warming, forest degradation, ecological deterioration, and drought and water shortages, more than half of the world's land is located in arid regions, so land desertification has become the number one ecological problem in the world. China has become one of the most severely affected countries by desertification. According to the survey, the potential range of desertification in China, that is, the total area of ​​arid, semi-arid and sub-humid dry areas is 3.317 million square kilometers, accounting for 34.6% of the total land area. Among them, 2.62 million square kilometers of desertified land is more than twice the total area of ​​cultivated land in China. In recent years, China's land desertification has been expanding. T...

Problems solved by technology

[0013] ① Fulvic acid is a small molecular organic acid extracted from weathered coal. Its anti-transpiration and anti-drought functions have also been recognized and applied at home and abroad, but there are the following weaknesses in practical applications: First, the water solubility of fulvic acid is poor. Therefore, it can only be a solution preparation in the product made, and the active ingredient content is not high (generally around 8%)

The second is the low resistance to hard water. It is easy to complex with calcium and magnesium ions in water to reduce its biological activity, especially when it is diluted with tap water or groundwater with high hardness, its function is limited.

Third, the surface tension of fulvic acid is large, the adhesion is weak, and the adhesion on the leaf surface of crops is low, and it is easy to form water droplets, which affects the absorption effect, especially when the spraying is uneven. Beads also cause foliar damage

[0014] ②Single function, only suppressing transpiration from the aspects of crop metabolism or film formation, while ignoring the nutrient balance and absorption of crops

This is also one of the main reasons for the low survival rate of afforestation in my country's "Three North" regions (North China, Northwest China, and Northeast China), low preservation rate, poor vegetation growth quality, and deterioration of the ecological environment.
