Within 10 days after the flowers of the fruit trees, the plant growth regulator with the concentration of 125-250 ppm is sprayed on the leaf surfaces of the fruit trees, so that the vegetative growth of leaves and branches can be obviously inhibited, the fruit bearing rate of the fruit trees is improved, the quality of fruits is improved, the yield is increased, and meanwhile, the fruit trees also have a good prevention effect on diseases caused by bacteria and fungi, such as fire blight and the like.
In summary, the following steps: the plant growth regulator containing prohexadione calcium and uniconazole and the application thereof provided by the invention have the advantages that the prohexadione calcium promotes the generation of chlorophyll, accelerates photosynthesis, phosphorus oxide promotes mitochondrial respiration, accelerates nutrition conversion, after a plant which is quantitatively sprayed with the pesticide absorbs the pesticide, the chlorophyll content can be improved, the mitochondrial respiration can be promoted to convert the product of the chlorophyll photosynthesis into the nutrient components of the plant, the metabolism rate of the plant is improved, the vegetative growth of the plant is regulated, the stem can be strengthened, the vigor can be controlled, the root can be promoted, the lodging resistance and the dwarfing can be realized after the plant growth regulator is applied, the stem leaves can be kept dark green, the leaves can be upright, the stress resistance of the plant can be improved, the disease resistance, cold resistance and drought resistance of the plant can be enhanced, and the high-concentration plant growth regulator can be sprayed after the plant is mature or the fruit thereof is mature, wherein the prohexadione calcium, the uniconazole and the pyraclostrobin, the photosynthesis is accelerated, the synthesis of gibberellic acid and morpheme is further inhibited, the fruit setting rate is improved, and the fruit ripening is promoted.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be able to cover the technical solutions disclosed in the present invention and the equivalent alternatives or modifications thereof within the scope of the present invention.
