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
The present invention relates to a kind of agriculturally useful compositions preparation, be used to improve the photosynthetic availability of wheat, improve the anti-salt of plant, cold-resistant, drought resisting, hot-dry wind tolerance ability, to reach the purpose of wheat high yield.
Background technology
As everyone knows, wheat belongs to the glycophyte of refusing salt, when soil salt is too much, can produce salt damage to wheat, and emergence rate descends, seedling is dead, and especially spring, period of seedling establishment salinization soil accumulation of salt in the surface soil phenomenon generally took place, and the wheat seedling death phenomenon is serious; Freeze injury, arid, dry-hot wind all are principal elements of wheat yield, and especially dry-hot wind is even more serious to the harm of wheat behind the rain of wheat milk ripe stage, the underproduction 10～20% or more than.Therefore, improve the wheat salt tolerance ability, avoid, alleviate natural calamity, receive Wheat Production and researcher's concern always.
Alleviating above-mentioned bad condition at present in the Wheat Production has the major measure that wheat influences: spray potassium dihydrogen phosphate, spray materials such as drought resistance agent fulvic acid, abscisic acid; Because its principle single (as regulating pore); And there is antagonism between different material; Whole degeneration-resistant effect is not remarkable, and some side effect (causing the plant photosynthetic efficiency to descend like abscisic acid) also can occur and cause wheat yield further to reduce.
