Problems solved by technology

Although there are many reports on the effects of plant growth regulators, medium and trace elements and other chemical substances on the growth and development of crops in the existing literature, there are few research materials on chemical regulation of drought, and even fewer production applications. The only chemical preparation is "Handilong", which belongs to the fulvic acid products, and the promotion area is not very large
The results of literature research show that the chemical substances that have a certain effect on crop drought resistance are abscisic acid [2] , cytokinin [3] , brassinolide [3,4] , Gibberellin [3,10] , Choline Chloride [3] , NAA [7] , fulvic acid [5,6] , betaine [8] , proline [9] , salicylic acid [11] , calcium chloride [10] , zinc sulfate [11] , rare earth [12] etc. Most of them belong to anti-transpiration agents, some of which are not ideal for single use and need to be used in conjunction with other substances
Anti-transpiration agents are based on the principle of closing stomata and reducing transpiration, but while reducing transpiration of crops, they also reduce photosynthesis, which causes adverse effects on plant growth while reducing water consumption

Embodiment 1

[0031] Embodiment 1 The present invention improves the compound preparation of wheat drought resistance and preparation method thereof

[0032] A compound preparation for improving drought resistance of wheat consists of plant nutrient, plant growth regulator, chemical inducer, auxiliary agent and water. Wherein plant nutrition is made up of 40% compound amino acid 250g / L, zinc sulfate heptahydrate 35.4g / L, ferrous sulfate heptahydrate 39.72g / L, boric acid 22.88g / L; -Sodium nitro-2-methoxyphenolate: sodium o-nitrophenolate: sodium p-nitrophenolate is 3:4:7) 2.5g / L and 50% chlormequat 2g / L composition, chemical inducer water Salicylic acid is 10g / L, the auxiliary agent is composed of ethanol 100g / L+glycerin 50g / L, and the balance is water (800ml).

[0033] The preparation method of the compound preparation for improving the drought resistance ability of wheat is carried out according to the following steps: take the inducer salicylic acid and dissolve it in the auxiliary agent...

Embodiment 2

[0038] Influence of the compound preparation of the present invention on the germination of wheat seeds under the artificial simulated drought stress of embodiment 2

[0039] At a room temperature of 20°C, the compound preparation prepared according to Example 1 of the present invention was diluted 200 times and then soaked for 12 hours. After the seeds were dried, the germination test was carried out in a light incubator with PEG to simulate drought stress, and clear water was used as a control. After the treatment, the seeds were put into a petri dish, and 3 mL of concentration was added into a hypertonic solution (19.2% PEG-6000 solution) of -0.5 MPa, and the germination potential of each treatment was counted on the 3rd day of cultivation, and the germination potential of each treatment was counted on the 7th day. Germination rate and relative germination rate, as well as shoot length, primary root number and primary root length of germinated seeds.

[0040] The result sho...

Embodiment 3

[0045] Effect of the compound preparation of the present invention on the growth and development of wheat seedlings under the drought stress of embodiment 3

[0046] At room temperature of 20°C, the compound preparation of the present invention is diluted 200 times and soaked for 12 hours. After drying, the seeds are sown in a germination box (14cm×20cm×12cm), placed in a solar greenhouse for cultivation, and 32 seedlings are settled after emergence, at the three-leaf stage given drought stress. When moderate drought occurred in the control group, samples were taken to measure plant height, fresh and dry weight of stems and leaves, dry weight of roots, and electrical conductivity.

[0047] The results show that: under drought stress, the wheat plant height, root dry weight, and stem dry weight of the soaked seeds of the compound preparation of the present invention are all significantly improved compared with the contrast, and the electrolyte exudation rate is lower than the c...

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,...
