Blueberry cultivation method in high-altitude areas

Abstract

The invention relates to a blueberry cultivation method, in particular to a blueberry cultivation method in high-altitude areas. The method comprises: blueberry varieties with strong cold resistance are selected and the seedlings are cultivated for 2 to 3 years by conventional methods, and the plants with 1 m above and main stem diameter as above 0.01 m are selected, the strong plants with three or more branches are used as the blueberry transplanting seedlings; and then the transplanting seedlings are transplanted to the high-altitude area with the altitude of more than 2600 m according to the planting density of 0.5 to 1m, and the row spacing of 1.0 to 2.0m. Through rational close planting, the higher yield is realized, and the time difference can be used to make up for the market spaceperiod, and the price of fresh fruit is high, and the better economic benefit is brought to the planting of the blueberries in the lower altitude area than in the middle and low altitude areas.

Description

technical field [0001] The invention belongs to the technical field of blueberry cultivation, and in particular relates to a method for cultivating blueberries in high altitude areas. Background technique [0002] Blueberry (Blueberry) belongs to Ericaceae (Ericaceae) genus Vaccinium (Vaccinium), scientific name bilberry, also known as bilberry, blueberry, is a perennial deciduous or evergreen shrub or small shrub tree species, the fruit is mostly blue-purple, soft Juicy, moderately sweet and sour, pure flavor, special aroma, rich in vitamin C, and high edible value. Blueberry fruit is rich in nutrients. It not only has good nutritional and health effects, but also prevents brain aging, strengthens the heart, fights cancer and softens blood vessels, enhances human body immunity, relieves eye fatigue, improves vision, anti-aging, and prevents urinary tract diseases. Infection, enhance memory, anti-cancer and other functions, is a natural source of pigment. [0003] There ar...

Problems solved by technology

Southwest China, especially the low-latitude and high-altitude areas above 2600m in Yunnan, has the characteristics of sufficient sunshine, large temperature difference between day and night, small annual average temperature difference, and abundant water resources, which are very conducive to the accumulation of blueberry fruit nutrition. However, high-altitude areas also have the characteristics of The characteristics of long frost period, cold climate and low effective accumulated temperature lead to slow growth and long childhood period of blueberries, making it difficult to plant and develop blueberries, and it is difficult to obtain economic benefits according to conventional planting methods

[0004] In addition, because the low-latitude and high-altitude areas, especially the low-latitude high-altitude areas above 2600m in Yunnan, are quite different from the mid-latitude low-altitude areas where artificially cultivated blueberries are currently planted, both in soil and climate, so it is applicable Blueberry cultivation methods in low-altitude areas of mid-latitude cannot be directly applied to areas of low-latitude and high-altitude areas
