Cultivation method of sweet cherry in alpine regions

Abstract

The invention discloses a cultivation method of sweet cherry in alpine regions comprising following steps: 1. garden selection: selecting areas with elevation of 700-1100m as cultivation regions; 2. variety selection: selecting following sweet cherry varieties: Kosmytchekaja, Summit, Brooks, Red lamp and Tieton; grafted seedlings of three years old or older or young seedlings of two years old or younger are selected as seedling, and Gisela dwarfing rootstocks are selected as the seedling stocks; 3. cultivation management: planting, shaping and trimming, fertilizing and watering management, and plant diseases and insect pests preventing; 4. rain shielding and sun shading measurement: filming before the end of March of first blooming and removing the film after fruit picking at the beginning of June to avoid rain; covering with sunshade screens at the beginning of June till the end of September and then removing the sunshade screens, wherein, the light transmittance of the sunshade screens is 40%.

Description

technical field [0001] The invention relates to a method for cultivating sweet cherries in high mountain areas, especially high mountain areas (700-1100m above sea level) in Zhejiang Province. Background technique [0002] Sweet cherries are beautiful in appearance, good in taste, and ripe early. They enjoy the reputation of "the first branch of spring fruit" and "jewel fruit". . The acreage and output of sweet cherries in the world are showing a linear upward trend. At present, the sweet cherry cultivation area in my country is 2 million mu, and the output is about 300,000 tons. The cultivation areas are concentrated in Shandong, Liaoning, Hebei, Shanxi and other northern regions. Vigorous, each region has a strong will to develop. In Zhejiang, there is no precedent for successful large-scale planting. Since the 1980s, many scientific research institutes and fruit growers in Zhejiang Province have repeatedly introduced different sweet cherry varieties to Zhejiang Provinc...

In Zhejiang, there is no precedent for successful large-scale planting

Since the 1980s, many scientific research institutes and fruit growers in Zhejiang Province have repeatedly introduced different sweet cherry varieties to Zhejiang Province for introduction and cultivation. to promote

However, planting sweet cherries on flat land in Zhejiang will face the problem of rain and heat in the same season. The rainfall far exceeds the needs of cherries, especially in May and June. During the flower bud differentiation period, high temperature and high humidity affect the flower bud development process, which may cause abortion of sweet cherry ovules and embryo sacs, resulting in flowers that are not fruitful and trees that grow too long

The overall fruit setting rate of sweet cherries is not high, and the economic benefits cannot meet expectations, which limits the large-scale cultivation in the warm regions of southern my country. Large-scale promotion requires the research of key technologies such as varieties and cultivation techniques.
