Problems solved by technology

[0005] At present, in the existing technology, because triacontanol is insoluble in water, its mixed application with other reagents is limited. The compatibility of the preparation is poor, mainly manifested in the precipitation of triacontanol due to demulsification and the decrease in activity

Embodiment 1

[0039] A. Add 150 kilograms of water to the reaction kettle, and then measure and add 0.8 kilograms of triacontanol crystals, 20 kilograms of Tween-80, and 10 kilograms of sodium lauryl sulfate in sequence, heat up to 80-90 ° C, and stir at high speed for 20 ~30min, cool down to below 45°C to obtain triacontanol emulsion;

[0040] B. Add 180 kilograms of betaine, 30 kilograms of ethoxylated trisiloxane, and 70 kilograms of calcium dodecylbenzenesulfonate to the triacontanol emulsion obtained in the upward step, and add the remaining amount of water to set the volume to 1000 kilograms , and high-speed shearing and stirring for 20-30 minutes, 1000 kg of the composition preparation can be obtained.

Embodiment 2

[0042] A. Add 200 kilograms of water to the reaction kettle, and then add 1.2 kilograms of triacontanol crystals, 25 kilograms of Tween-80, and 15 kilograms of sodium lauryl sulfate in sequence, heat up to 80-90 ° C, and stir at high speed for 20 ~30min, cool down to below 45°C to obtain triacontanol emulsion;

[0043] B. Add 150 kilograms of betaine, 20 kilograms of ethoxylated trisiloxane, and 100 kilograms of calcium dodecylbenzenesulfonate to the triacontanol emulsion obtained in the upward step, and add the remaining amount of water to set the volume to 1000 kilograms , and high-speed shearing and stirring for 20-30 minutes, 1000 kg of the composition preparation can be obtained.

[0044] The composition preparation prepared in the above examples is diluted 1200 times with water, and can be used for soaking wheat seeds to increase the emergence rate of wheat, enhance the salt resistance and cold resistance of wheat, and increase effective tillering; the composition preparat...

Abstract

The invention discloses a composition capable of increasing wheat yield, which includes, by weight, 15%-18% of betaine, 0.08%-0.12% of triacontanol, 3%-4% of emulsifier, 10%-12% of dispersing-spreading agent, and the balance of water. The method of preparing the composition includes: A, preparing triacontanol emulsion; firstly, adding water in a reactor, sequentially adding triacontanol crystal and the emulsifier, heating to 80-90 DEG C, shearing and stirring at high speed for 20-30 minutes, and cooling to below 45 DEG C to obtain the triacontanol emulsion; and B, adding the betaine, the dispersing-spreading agent and water into the triacontanol emulsion obtained in the former step, and shearing and stirring at high speed for 20-30 minutes to obtain the composition. By means of the composition, photosynthetic efficiency of wheat can be increased, and further, salt resistance, cold resistance, drought resistance and dry-hot wind resistance of plants can be improved while the effects are stable.

Description

technical field [0001] The invention relates to an agricultural composition preparation, which is used for improving the photosynthetic utilization rate of wheat, improving the salt resistance, cold resistance, drought resistance and dry hot wind resistance of plants, so as to achieve the purpose of high yield of wheat. Background technique [0002] As we all know, wheat is a salt-repelling light-soil plant. When the soil is too salty, it will cause salt damage to wheat, the emergence rate will decrease, and the seedlings will die. Especially in the spring greening period, salinization of salinized soil returns to salt commonly occurs, and the dead seedlings of wheat are serious; Freezing injury, drought, and hot and dry wind are the main factors for wheat production reduction, especially the dry and hot wind after rain in the milky stage of wheat is more harmful to wheat, and the yield is reduced by 10-20% or more. Therefore, improving the salt-tolerant ability of wheat and...
