A Method Applicable to Southwest Highlands to Improve the Fruit Setting Rate of Large Cherry

Abstract

The invention discloses a method suitable for increasing the fruit setting rate of large cherries in high-altitude areas in Southwest China. Carry out disinfection treatment, then install columns, and put a sunshade net on the orchard; water the orchard thoroughly before the tree germinates in spring, and then cover the tree tray with plastic film; spray a self-made fruit-setting agent at the blooming stage and early fruit-setting stage of the big cherry; Remove the sunshade net in time after the fruit-setting period of the big cherry; during the fruit growth period of the big cherry, water it in time and spray potassium dihydrogen phosphate solution for top dressing outside the root. In addition, pay attention to observe whether there are pests and diseases, and carry out comprehensive prevention and control according to the characteristics of pests and diseases. The invention is simple and easy to operate, and can effectively increase the fruit setting rate and output of the big cherry. Tests show that the fruit setting rate can be increased by 40.50%, and the output can be increased by 52.80%.

Description

technical field [0001] The invention relates to a fruit tree cultivation method and belongs to the field of plant cultivation. Background technique [0002] Big cherries, also known as sweet cherries and cherries, are a temperate deciduous fruit tree. The fruit is rich in nutrients, and has the functions of beautifying and beautifying, regulating the 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 adopted with reference to the main producing areas in the north. Due to the small annual temperature difference in this area and the warmer winters, most large cherry varieties need insufficient cooling when cultivated in this area. It usually shows that the plant enters the dormancy time later, and the dormancy is insufficient. After the spring, the plant germination i...

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.
