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 activit

Embodiment 1

[0051] The method for preparing a multifunctional transpiration inhibitor is as follows:

[0052] Step 1: Preparation of organic rare earth

[0053] Add 2 kg of rare earth nitrate into the reactor, and then add 40 kg of deionized water. After mixing, heat to 30°C, stir until the rare earth is dissolved, add 2.2 kg of disodium edetate, and adjust the pH after mixing. When the value reaches 9, heat to 50°C to react for 5 hours. After evaporating the liquid, the solid is dried and then pulverized to obtain chelated organic rare earth for use.

[0054] Step 2: Preparation of chelated trace elements

[0055] Add a total of 10 kilograms of copper sulfate, zinc sulfate, ferrous sulfate, and manganese sulfate to 200 kilograms of deionized water, and then add 10 kilograms 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 later use.

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

Embodiment 2

[0060] The steps of the method for preparing the multifunctional transpiration inhibitor are the same as those in Example 1; the difference is that the formula is as follows:

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

Embodiment 3

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

[0064] The steps of the method for preparing a multifunctional transpiration inhibitor are the same as in Example 1;

[0065] The compound of multifunctional transpiration inhibitor: It is formulated according to the following weight ratio.

[0066] Take organic rare earth 0.10Kg, chelate trace elements 1.2Kg, and then mix with CMC 2.5Kg, HEMC 3.0Kg, biochemical fulvic acid 2.3Kg, sodium hexametaphosphate 0.5Kg, polyacrylamide 0.30Kg, sodium a-naphthalene acetate 0.1Kg , A total of 10Kg, dry mixed, ball milled into powder or add 100 liters of deionized water to make 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 the global warming, forest degradation, ecological deterioration and drought and water shortage, more than half of the world's land is located in arid areas, so land desertification has become the world's number one ecological problem. China has become one of the countries most severely affected by desertification. The survey shows that the area of ​​potential desertification in China, namely the arid, semi-arid, and sub-humid arid regions, covers a total area of ​​3.317 million square kilometers, accounting for 34.6% of the total land area. Among them, the desertified land is 2.62 million square kilometers, which is more than twice the total cultivated area of ​​the country. In recent years, China’s land desertification has been expandi...
