Problems solved by technology

[0011] ① Fulvic acid (MFA) 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 Poor water solubility
The second is the low resistance to hard water, and it is easy to complex with calcium and magnesium ions in water to reduce its biological activity.
[0012] 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.

Embodiment 1

[0051] The preparation method of multifunctional transpiration inhibitor is as follows:

[0052] The first step: preparation of organic rare earth

[0053] Add 2kg of rare earth nitrate to the reaction kettle, then add 40Kg of deionized water, mix well, heat to 30°C, stir until the rare earth dissolves, add 2.2kg of disodium edetate, mix well, adjust the pH value to 9, heated to 50 ° C for 5 hours, evaporated the liquid, dried the solid, and then pulverized to obtain the chelated organic rare earth for future use.

[0054] The second step: preparation of chelated trace elements

[0055] Add a total of 10 kg of copper sulfate, zinc sulfate, ferrous sulfate, and manganese sulfate in equal proportions to 200 kg of deionized water, then add 10 kg of disodium edetate, mix well, and adjust the pH value to 8, react at 40°C for 4 hours, evaporate and dry to obtain various chelated trace elements for future use.

[0056] The third step: ① Take the above-mentioned chelated organic ra...

Embodiment 2

[0060] Prepare multifunctional transpiration inhibitor method step with embodiment 1; Difference is that formula is as follows:

[0061] Take 0.35Kg of organic rare earth, 0.7Kg of chelated trace elements, and 2.6Kg of CMC, 0.9Kg of biochemical fulvic acid, 0.2Kg of sodium hexametaphosphate, 0.15Kg of polyacrylamide, and 0.1Kg of а-naphthalene acetate, a total of 5Kg, Mix, add 50 liters of deionized water to dissolve and make liquid preparation.

Embodiment 3

[0063] When this product is used in winter or early spring in the northern region for windproof, anti-stripping and cold resistance of seedlings, the proportion of cellulose ether and polyacrylamide can be increased appropriately.

[0064] Prepare multifunctional transpiration inhibitor method steps with embodiment 1;

[0065] Compounding of multifunctional transpiration inhibitors: prepared according to the following weight ratio.

[0066] Take 0.10Kg of organic rare earth, 1.2Kg of chelated trace elements, and then mix with 2.5Kg of CMC, 3.0Kg of HEMC, 2.3Kg of biochemical fulvic acid, 0.5Kg of sodium hexametaphosphate, 0.30Kg of polyacrylamide, and 0.1Kg of sodium а-naphthalene acetate , a total of 10Kg, dry mixed, made into a powder after ball milling or adding 100 liters of deionized water to make a liquid.

Abstract

The invention discloses a multifunctional transpiration inhibitor which comprises the following ingredients in percentage by weight: 35-55 percent of cellulose ether, 9-26 percent of biochemical fulvic acid powder, 1-9 percent of organic rare earth, 1-5 percent of sodium hexametaphosphate, 5-20 percent of chelating trace elements, 0-3.5 percent of polyacrylamide and 0-2 percent of Alpha-sodium acetate; wherein the organic rare earth is rare earth prepared from the chelation reaction by adopting a chelating agent; the chelating trace elements are generated by adding ionized water and the chelating agent into the combination of copper sulfate, zinc sulfate, ferrous sulfate and manganese sulfate for performing the chelation reaction; and the cellulose ether is series products of water-soluble cellulose ethers. The multifunctional transpiration inhibitor has the functions of inhibiting transpiration, resisting drought and wind, strengthening nutrition, and the like, can improve the survival ratio, the preservation ratio and the survival state of plants, further enhance the capacities of resisting stress, diseases, draught, cold and the like of the plants and achieves the aims of resisting draught and saving water, ensuring seedlings to survive as well as increasing both production and income.

Description

technical field [0001] The invention belongs to the technical field of environmental ecology (agriculture and forestry), and relates to a multifunctional transpiration inhibitor 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 countries most seriously affected by desertification. According to the survey, the areas where desertification may occur in China, that is, the total area of ​​arid, semi-arid and sub-humid arid areas are 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 expandi...
