Example Embodiment

[0019] Example 1

[0020] Take 500g of reed pulp papermaking waste liquid containing 45% of the liquid, and another 100g of urea-formaldehyde resin solution; start the reaction stirring device, increase the temperature to 85~90℃, add 500g reed pulp papermaking waste liquid, namely sulfonate magnesium salt lignin liquid, adjust Between PH7-8, slowly add urea-formaldehyde resin solution, stir and react for 1 hour, then add 1g of polyvinyl alcohol or acrylamide, continue to stir and react for 1 hour, and dry to obtain yellow-brown powder. When using, mix it with 1% aqueous solution and spray it.

Example Embodiment

[0021] Example 2

[0022] Take 500g of reed pulp papermaking waste liquid containing 45% of the liquid, and another 300g of urea-formaldehyde resin solution; start the reaction stirring device, increase the temperature to 85-90℃, add 500g reed pulp papermaking waste liquid, that is, the magnesium sulfonate lignin liquid, adjust Between PH7-8, slowly add urea-formaldehyde resin solution, stir and react for 1 hour, then add 3g of polyvinyl alcohol or acrylamide, continue to stir and react for 1 hour, and dry to obtain yellow-brown powder. When using, mix it with 1% aqueous solution and spray it.

Example Embodiment

[0023] Example 3

[0024] Take 250g reed pulp papermaking waste liquid dry base material, namely dry base sulfonate magnesium salt lignin, dilute with 500ml water, and take another 150g urea-formaldehyde resin solution; start the reaction stirring device, heat up 85~90℃, add 500g reed pulp papermaking waste Diluent of liquid-dry base material, adjust PH between 7-8, slowly add urea-formaldehyde resin solution, stir and react for 1 hour, then add 1.5g of polyvinyl alcohol or acrylamide, continue to stir and react for 1 hour, and dry to obtain yellow Brown powder. When using, mix it with 1% aqueous solution and spray it.

Abstract

The invention discloses a drought-fighting and seedling-protection growth promoter for crops. The drought-fighting and seedling-protection growth promoter is prepared by diluting reed pulp papermaking waste liquid or a dried base material of the reed pulp papermaking waste liquid by water, mixing the reed pulp papermaking waste liquid or the dried base material thereof and urea resin serving as an enhancement agent as well as polyvinyl alcohol or acrylamide serving as a viscosifier and then drying the product. The weight ratio of the reed pulp papermaking waste liquid to the enhancement agent is 1:0.2-0.6; and the weight ratio of the reed pulp papermaking waste liquid to the viscosifier is 1:0.002-0.006. A solution prepared by the product with the concentration of 1 percent is sprayed on a drought crop soil layer; under the influence of wind and solarization, the surface of the soil quickly becomes a colloid film which is 0.5 mm thick and is used for preventing water from being evaporated; in rainy days, the colloid film is softened to absorb water; in sunny days, the colloid film is solidified to keep the water; therefore, the drought-fighting and seedling-protection growth promoter is non-toxic and harmless and cannot cause secondary pollution; the drought-fighting and seedling-protection growth promoter can be naturally degraded after 180 days.

Description

technical field [0001] The invention relates to a drought-resistant and seedling-preserving growth-promoting agent for crops and a preparation method thereof. Background technique [0002] my country is a large agricultural country, and most agriculture depends on the weather. If there is no rain, the growth of crops will be seriously affected by drought. The emergence of crops will be low due to drought, and the reduction in crop production will directly affect the country's food security. Some anti-drought agents currently used, such as anti-transpiration agents, are not stable enough and are not conducive to photosynthesis of plants; some anti-drought agents have complicated production processes and high prices, so they are not suitable for promotion. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a drought-resistant and seedling-preserving growth-promoting agent for crops capable of a...
