Method for increasing fruit setting rate of large cherries suitable for southwest highlands

Abstract

The invention discloses a method for increasing the fruit setting rate of large cherries suitable for southwest highlands. The method includes the following steps that a base fertilizer is applied sufficiently in autumn, an orchard is subjected to pruning, leaves are removed manually, a lime-sulphur mixture diluent is sprayed for disinfecting the orchard, the stand columns are installed, and a shading net is put in the orchard; the orchard is watered before trees germinate at the beginning of spring, and then the ground projection areas of tree crowns are covered with mulching films; a homemade fruit-setting agent is sprayed during the blooming period and the early fruit-setting period of the large cherries; after the fruit-setting period of the large cherries is over, the shading net is removed in time; during the large cherry fruit growth period, watering is carried out in time, and a potassium dihydrogen phosphate solution is sprayed for foliage top-dressing; and in addition, whether insects and diseases occur or not needs to be paid attention to, and comprehensive prevention and control is carried out according to the characteristics of the occurrence of insects and diseases. The method is simple and easy to operate, and convenient to operate, the fruit-setting rate and yield of large cherries can be effectively improved, tests show that the fruit-setting rate can be increased by 40.50%, and the yield can be increased by 52.80%.

Description

technical field [0001] The invention relates to a method for cultivating fruit trees and belongs to the field of plant cultivation. Background technique [0002] Cherry, also known as sweet cherry or cherry, is a temperate deciduous fruit tree. The fruit is rich in nutrients and has the functions of beautifying and nourishing the skin, regulating the middle and replenishing qi, and dispelling rheumatism. So far, the cultivation area of ​​big cherries in the high-altitude areas of Southwest my country has exceeded 10,000 hm 2 . When cultivating large cherries in this area, the traditional flower and fruit management mode is usually used in reference to the main production areas in the north. Since the annual temperature difference in this area is relatively small and the winter is relatively warm, most large cherry varieties need insufficient cooling when cultivated in this area.

Problems solved by technology

When cultivating large cherries in this area, the traditional flower and fruit management mode is usually used in reference to the main production areas in the north. Since the annual temperature difference in this area is relatively small and the winter is relatively warm, most large cherry varieties need insufficient cooling when cultivated in this area. It usually shows that the dormancy time of the plant is late, and the dormancy is not sufficient, and the budding of the plant is delayed after the spring, the flowering is delayed, the flower organ is deformed, and the fruit setting rate is low.

In addition, this area is prone to low temperature weather during the flowering and fruit-setting stages of plants, which is prone to freezing damage to plant flower organs and young fruits, resulting in a large number of flower and fruit drop, which seriously affects plant yield.
