Cultivation method for promoting large cherries to ripen earlier by utilizing natural climate in plateau area

Abstract

The invention discloses a cultivation method for promoting large cherries to ripen earlier by utilizing natural climate in a plateau area, and belongs to the technical field of large cheery planting. The cultivation method is characterized by adopting a conventional outdoor cultivation method and utilizing the natural climate and a plastic thermal-insulation shed to carry out temperature regulation management on large cherries. The cultivation method specifically comprises the following steps: (1) selecting a variety; (2) building the plastic thermal-insulation shed; (3) sleeping forcibly; (4) carrying out cultivation management at a germinating and flowering period; (5) carrying out cultivation management at a fruit-setting and growing period; and (6) carrying out cultivation management at a fruit-expanding, coloring and ripening period. According to the cultivation method disclosed by the invention, a natural temperature is utilized to regulate a temperature needed for different growth periods of large cherry trees, good characteristics and quality of large cherries produced outdoors are kept, the large cherry trees continuously sleep for 30 days, and the large cherries only need 45-55 days from the germinating and flowering period to the mature period. Besides, the cultivation method further can effectively save energy consumption, can save electricity consumption by 5000 degrees within a planting period per year per mu of large cherries, so that planting cost is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of planting large cherries, and in particular relates to a cultivation method for promoting early ripening of large cherries by using natural climate in plateau areas. Background technique [0002] There are three main categories of cherries: American cherries, European sweet cherries and Chinese cherries. Other varieties are cultivated on the basis of these three categories. The nutritional value of cherries is very high: the iron content per 100 grams of cherries is as high as 5.9 mg, ranking first in the fruit family; the content of carotene is 4 to 5 times more than that of grapes, apples, and oranges; in addition, cherries also contain vitamins B and C and minerals such as calcium and phosphorus. Cherries have rich nutritional value, but fresh cherries are thin and difficult to preserve, and they generally mature in April-May every year, which cannot meet the large demand for cherries before and after ...

Problems solved by technology

But this method still has the following defects: one is to spray the cherry trees with low-temperature water to cool down after picking the leaves manually, and to transfer the cherry trees to high altitudes. The normal dormancy of cherries requires a lot of manual labor, low efficiency, high labor costs, and is not suitable for large-scale and industrialized development; second, it is highly dependent on natural conditions and climate, and cannot control the dormancy temperature, germination and flowering temperature of cherry trees, The temperature at the fruit setting stage and the temperature at the ripening stage of fruit swelling and coloring will bring huge losses to growers in case of severe and extreme weather, and in the later stage of fruit setting and ripening, the temperature at night above 1km above sea level is lower than 7°C, Therefore, the temperature is low, which is not suitable for fruit setting and ripening of cherries, resulting in low fruit setting rate, poor coloring and reduced quality when ripe
