Strengthen young fruit management to reduce physiological fruit drop

Pear, peach, apple, kiwifruit, citrus, jujube and other fruit trees will occur physiological fruit drop phenomenon in the young fruit period. The fruit drop production is closely related to fruit development progress and growth dynamics of vegetative organs, mainly depends on the nutrition of the tree. status.

The period of young fruit is the period when a large number of new leaves are continuously developed. The competitiveness of leaves for nutrients is better than that of young fruit. Young fruit is often starved due to lack of competition for nutrient absorption, resulting in shedding. Therefore, to reduce the occurrence of physiological fruiting, only increase the tree nutrients and young fruit competitiveness of nutrient absorption.

The period of young fruit is exactly the period of rapid cell division, and the number of cell divisions at this time determines the size of the future fruit. The number of cell divisions of young fruit is large, and the large fruit-type fruits that will be formed in the future will be large and the amount of fruit growers will increase, which will increase the income.

The benefits of “Shufeng 481” in young fruit spray: Firstly, to increase the hormone level of young fruit, enhance its competitiveness in nutrient absorption to promote cell division, and secondly, increase the chlorophyll content of leaves and increase the photosynthetic intensity of leaves. The photosynthetic products of the leaves are greatly increased, and the nutrient requirements of new leaves and young fruits are satisfied at the same time, and the occurrence of physiological fruit drop is reduced. A large number of photosynthetic products provide sufficient nutrients for the rapid division of young fruit cells. The greater the number of young fruit cell divisions, the greater the amount of fruits that will be formed in the future and the greater the amount, and the income of the fruit farmers will also be greatly increased.

"Shuonfeng 481" is a large fruit by promoting cell division and increasing the number of cells. The increase in the number of its peel cells greatly reduces the occurrence of physiological fruit drop and reduces fruit rot and fruit loss due to fruit cracking. After application, the skin is thin, bright and bright, avoiding the skin thickness, oily skin floating fruit, and non-residue that appeared due to the use of 90%. "Shu-feng 481" can be mixed with neutral, weakly acidic pesticides, generally with 6 grams per acre or 15 milliliters of watered 45-60 kilograms evenly spray, rain within 4 hours should be sprayed as appropriate. In the different stages of development of fruit trees, such as flower bud stage, young fruit stage, fruit enlargement stage and coloring stage, the “Shuofeng 481” is used together with the drugs, which results in large fruit, good taste, less rust, high yield, and low income of the farmers.
