Abstract

The invention relates to resistance preparations of crops and use methods therefor, particularly relates to a compound preparation for improving drought resistance of wheat and a use method therefor and belongs to the technical field of agriculture. The compound preparation consists of plant nutritional agents, plant growth regulators, a chemical induction resisting agent, an adjuvant and water, wherein the plant nutritional agents consist of composite amino acid, a zinc salt, a ferric salt, boric acid or salts thereof, the plant growth regulators consist of compound sodium nitrophenolate and cycocel, the chemical induction resisting agent is salicylic acid, and the adjuvant is a mixture of ethanol and glycerine. The compound preparation disclosed by the invention can be used for improving and supplementing nutrition and reducing transpiration, so that the relative water content of leaves under adverse circumstances is increased, the damage to cell membranes under the adverse circumstances is reduced, and then, the photochemical efficiency under the adverse circumstances is increased; and after the compound preparation is used, the drought resistance of the wheat can be remarkably enhanced, and the wheat can maintain normal growth and development and achieve relatively good yield and quality.

Description

technical field

[0001] The invention relates to a crop anti-adversity preparation and a use method thereof, in particular to a compound preparation for improving the drought resistance ability of wheat and a use method thereof, belonging to the field of agricultural technology. Background technique

[0002] Wheat is the second largest food crop in the world, and 70% of its planting area is distributed in arid and semi-arid regions. In wheat production, drought stress has become an important factor limiting wheat yield. The annual wheat production loss caused by different degrees of drought in various parts of the world accounts for about 30% of the total wheat production, and the wheat production loss caused by drought in my country is about the sum of the production losses caused by other natural disasters. Drought has many adverse effects on the growth and physiological metabolism of wheat, such as the decrease of tissue water content, the decrease of photosynthetic rate,...
