Preparation for preventing physiological fruit drop of apples and usage method thereof

Abstract

The invention relates to a preparation for preventing physiological fruit drop of apples and its usage method, belonging to the technical field of fruit tree preparations. Aiming at the problem of pre-harvest fruit drop of the new apple variety Weihai Golden and the poor control effect of existing fruit drop prevention agents on the market on pre-harvest fruit drop of Weihai Golden apples, the invention provides a preparation for preventing physiological fruit drop of apples and its usage method. The active ingredients of the preparation for preventing physiological fruit drop of apples consist of 15-25 parts by weight of naphthaleneacetic acid, 150-250 parts by weight of isobutyric acid, 30-50 parts by weight of Astragalus membranaceus extract, 30-50 parts by weight of Scutellaria baicalensis extract, and 30-50 parts by weight of Pueraria lobata extract. Experiments have found that the preparation for preventing physiological fruit drop of apples can effectively control pre-harvest fruit drop of apples, and at the same time, it is beneficial to flowering, improves fruit quality, and enhances tree vigor. When the preparation for preventing physiological fruit drop of apples is matched with the modern dwarfing rootstock cultivation mode, its control effect is better, and it is suitable for popularization and application.
