Reasons for the kiwi fruiter to drop fruit:
First, nutrition is single. At present, fruit farmers management orchards generally have the advantages of “heavy yield, light weight, heavy inorganicity, light organicity, heavy weight, slight quantity, heavy underground, light groundâ€, resulting in unscientific and unbalanced ratios of various elements of crops. It affects the balanced absorption and utilization of nutrients by plants, and it is easy to induce deficiency diseases and cause fruit drop.
Second, serious "overload". Due to the kiwifruit varieties such as Huayou, Hongyang and Early Gold, the buds are dense, frost-resistant and have a high rate of germination. If the germination, topping and sparseness are not emphasized, the nutrient is inefficiently consumed. Once it enters the reproductive growth stage, the tree The potential will gradually weaken, and the nutrients necessary for fruit growth will not be guaranteed, which will inevitably lead to falling flowers, fruit drop, and even premature aging.
Third, the tree is prosperous. Because the vegetative growth is too strong, a large amount of nutrients are consumed by the shoots, and the fruit-bearing stamina is insufficient, causing almost all the large fruits on the periphery of the fruit trees to fall off, and it will induce ulcer disease in the coming year.
Fourth, ignore prevention. Anti-insect sterilization after flowering and porcine carbendazim calcium supplementation are very important. If the nutrition is not prevented and supplemented in advance, the bacteria will fall into the wound from the petals.
Fifth, the abuse of hormones. Due to the use of "Daguoling" on kiwifruit in some places in recent years, the cell division is too fast, causing the heart to crack, harden and brown, and the flesh is slack. The fruit has poor disease resistance.
Sixth, the bagging is too early. Due to the excessive weight of the fruit, the proportion of leaves and fruits is seriously dysfunctional, and the fruit burning is serious. Fruit farmers bagging time is generally advanced. It is recommended that the bagging should be better than high temperature weather, and the bagging is best after coloring, and the method of appropriately increasing the thickness of the leaf layer layer can be adopted to cancel the bagging.
