Embodiment 1

[0056] Biological Assay Example 1: Determination of the synergistic effect of melatonin and pyraclostrobin on low temperature stress in wheat

[0057] Test object: the wheat variety is Yannong 19, purchased from the seed market;

[0058] Test method: The seeds were sterilized with 10% potassium permanganate liquid for 10 minutes, washed repeatedly with distilled water, and placed in a constant temperature incubator at 25° to accelerate germination. When the seeds are 95% white, they are sown in plastic cups equipped with vermiculite, and 10 seeds are sown in each plastic cup. It is grown under the culture environment conditions of temperature 20°, illuminance (PAR) 250umol / (m2.s), relative humidity 50%, and light 14h / d. Water the Hoagland nutrient solution with a pH of 5.5 every 4 days.

[0059]Quantitative melatonin was weighed, dissolved in absolute ethanol, and 1.5% Tween-80 was added to form a 2.5% solution. Quantitative pyraclostrobin was dissolved in acetone, and 1.5%...

[0074] Biological Assay Example 2: Determination of the synergistic effect of melatonin and thiamethoxam on low temperature stress in wheat

[0075] Test object: the wheat variety is Yannong 19, purchased from the seed market;

[0076] Test method: The seeds were sterilized with 10% potassium permanganate liquid for 10 minutes, washed repeatedly with distilled water, and placed in a constant temperature incubator at 25° to accelerate germination. When the seeds are 95% white, they are sown in plastic cups equipped with vermiculite, and 10 seeds are sown in each plastic cup. It is grown under the culture environment conditions of temperature 20°, illuminance (PAR) 250umol / (m2.s), relative humidity 50%, and light 14h / d. Water the Hoagland nutrient solution with a pH of 5.5 every 4 days.

[0077] Quantitative melatonin was weighed, dissolved in absolute ethanol, and 1.5% Tween-80 was added to form a 2.5% solution. Quantitative thiamethoxam was dissolved in methanol, and 1.5% T...

Abstract

The invention discloses an anti-freezing yield-increasing composition for flight control and a preparation method thereof. The composition comprises melatonin, pyraclostrobin and thiamethoxam in a specific proportion. The composition disclosed by the invention can effectively solve the problems of drifting, demulsification, flocculation and the like in flight control operation, does not contain organic solvents, is safe to produce and use, and is environment-friendly; the anti-freezing property of crops can be remarkably improved, and the adverse effect of freezing injury on the crops is delayed; besides, the thousand-seed-weight can be increased, and the final yield of crops is increased.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to an antifreeze production-increasing composition which can be used for aerial defense and a preparation method thereof. The composition contains melatonin, pyraclostrobin and thiamethoxam in specific proportions. Background technique [0002] In recent years, national policies have encouraged appropriate-scale land processes, and family farm planting has gradually become the main body of large-scale planting, which has played a positive role in promoting my country's grain planting. The family farm model can not only improve the management level of planting, but also increase the income per unit area. It is a win-win model that serves multiple purposes. [0003] For growers contracting thousands of acres or even tens of thousands of acres, there are three bottlenecks in the planting process that need to be solved urgently. The first bottleneck is the spraying probl...
