Sandy land cherry off-season cultivation method

Abstract

The invention relates to a sandy land cherry off-season cultivation method. The method comprises the steps of a, applying base fertilizers, applying decay sheep manures for 5 cubes, and covering mellow soil for 40cm to 60cm thick; b, performing field planting in accordance with line spacing in a range of 2.8m to 3m and the line spacing of 1.5m in the last ten-day of March; c, performing irrigation 4 times between May and September; d, taking film insulation measures when the temperature is lower than minus 15 DEG C and cherry trees fall leaves in September; e, performing pruning trimming regularly in the first three years after planting of cherry trees, and guaranteeing that the temperature in a greenhouse is not lower than minus 15 DEG C; f, controlling dormancy after leaf falling at the end of October when the cherry trees bear fruits in the fourth year of planting; covering film and quilts at the end of December to enable the temperature in the greenhouse to be maintained in a range of 15 DEG C to 30 DEG C and the humidity to be in a range of 60% to 80%, and ending dormancy in advance; g, picking cherries at the end of May. By the aid of the method, planting of cherries in sandy lands is introduced, released bees are used for pollination, and accordingly, the pollination rate is improved; the cherry tree dormancy period is shortened, and the cherries come into the market ahead of time.

Description

technical field [0001] The invention relates to the field of facility agriculture, in particular to an off-season cultivation method for cherries in sandy land. Background technique [0002] The fruit of the big cherry matures early, and it has the reputation of "the first fresh fruit of primrose". It is favored by consumers for its bright color, high quality, rich nutrition and high value. It is favored by growers because of its high economic benefits, short fruit growth period, and easy management. However, in production, there is a late formation of economic output and slow effect, which restricts the development of big cherries. Therefore, it is the key to promote the development of big cherry to explore the early high-yield technology of big cherry. [0003] Cherry likes warmth and is not cold-resistant or drought-tolerant. It is suitable for cultivation in areas with an average annual temperature of 10°C-15°C. When the temperature is higher than 15°C, large che...
