Description

Technical Field

[0001] The present invention relates to the technical field of agriculture, in particular to a foliar spray for crops. Background Art

[0002] In agricultural production, "depending on the weather for food" is a commonplace topic. Weather conditions influence crop yields: good weather means a good harvest, while bad weather leads to poor results. The weather situation is complex, with significant climate anomalies and frequent extreme events. The national average temperature reached 10.5°C, the second highest since 1961, second only to 2021. The summer heatwave reached a record high, and torrential rains were frequent, causing severe flooding in South China and Northeast China.

[0003] Agricultural products are closely related to our lives, but there is a general oversupply of agricultural products, and safety issues continue to emerge. This is mainly because the homogenization of agricultural products is becoming increasingly serious. There is very little difference between similar agricultural products from the inside out. Indicators such as sweetness, taste, shape, and nutritional content are highly similar. Coupled with blindly following the trend of planting, agricultural product prices are unstable and the market is mixed. As a result, it is difficult for growers to sell, which easily leads to sluggish sales, and it is difficult for consumers to distinguish whether they are authentic and healthy.

[0004] New methods are needed to solve the problems of crop stress resistance, promoting photosynthesis, promoting growth, improving crop quality and storage time. Summary of the Invention

[0005] The purpose of the present invention is to provide a foliar spray for crops to solve the problems of crop stress resistance, promoting photosynthesis, promoting growth, improving crop quality and storage time.

[0006] In order to achieve the above objectives, the present invention provides the following technical solutions: A foliar spray for crops is composed of the following components by weight: 18%-24% dodecanol, 9%-12% hexadecanol, 0.6%-0.9% emulsifier, 0.36%-0.48% n-butanol, 2.3%-2.7% regulator, and 55%-70% water.

[0007] Furthermore, the emulsifier is one or more combinations of tea saponin, high-carbon fatty alcohol polyoxyethylene ether, and fatty acid polyoxyethylene ester.

[0008] Furthermore, the regulator is one or more combinations of gum arabic, xanthan gum, and methyl cellulose.

[0009] The present invention provides a method for preparing a foliar spray for crops, characterized in that the method comprises the following steps: Add dodecanol and hexadecanol to a container and heat until melted. Add emulsifier and n-butanol to the container and process it through a high shear homogenizer. Set the speed to 5000 rpm and the processing time to 10 minutes. Then add water at 60 to 80 degrees to the container, set the speed to 10000 rpm and the processing time to 30 minutes, and cool it to room temperature.

[0010] The present invention also provides a method for applying the crop foliar spray, which comprises diluting the foliar spray by 300 to 500 times with water and then spraying the foliar spray on the surface of crop leaves.

[0011] It can be seen from the above technical solutions that the crop foliar spray provided by the present invention forms a protective film on the surface of crop leaves, promotes leaf photosynthesis, protects against sunburn, improves quality and yield, and enhances storage resistance.
