When the fruit enters the rapid expansion stage or near maturity, no signs of pests and diseases are visible, but a large number of fruit fallouts often occur, resulting in reduced yields and yields. Presently, four measures of production are introduced to effectively reduce apple fruit drop.
First, thinning and thinning fruit. Too dense flowers will cause poor nutrition and metabolic disorders in the tree. In the period of fruit's rapid expansion or near maturity, if nutrition fails to follow, it will lead to a large amount of fruit shedding. Therefore, scientific and rational thinning of fruit and fruit is one of the effective measures to prevent fruit shedding.
Second, under the tree top dressing. According to the orchard's fertility foundation and tree nutrient status, nitrogen, phosphorus, and potassium fertilizers can be applied to the fruit trees 20-30 days before the physiological fruiting. It is better to apply high-quality organic fertilizers for prevention.
Third, foliar spray fertilizer. To quickly supplement the tree's nutrition, reduce the degree of fruit drop, near the physiological fruit drop, can be sprayed 2-3 times continuously. In order to achieve the goal of improving fruit quality at the same time, spray 0.5% urea and 0.4% potassium dihydrogen phosphate solution.
Fourth, spraying plant growth regulators. Before the arrival of physiological fruit drop, spray once every 10-15 days with a concentration of 20-40ppm naphthalene acetic acid, continuous spraying 2-3 times, can effectively control the physiological fruit drop, but this measure must be established on the basis of improving the nutrition of the tree. It is only effective, and the physiological fruit drop caused by other reasons is not obvious.
