The planting method of the first crop of grapes in the northern solar greenhouse twice a year

Abstract

The invention discloses a one-year-two-harvest cultivation method for sunlight greenhouse grape first-fruit in a north area. The method comprises the following steps: 1) selecting variety; 2) managing in planting year; 3) managing in the second and later year. According to the method, the high yield in current year and one-year-two-harvest effect of grape first-fruit are realized by utilizing the effective regulation of sunlight greenhouse for the temperature in each growth period of the grape, taking the management technical measures of reasonable watering fertilizing, pinching and tip-remaining, trimming fallen leaves, accelerating germination, and the like, stimulating the winter buds to germinate in the same year and starting the second growth period in the same year; the growth period and harvest period of the fruit at two times are totally not overlapped; and meanwhile, through the reasonable temperature regulation of the sunlight greenhouse, the two mature periods can avoid the concentrated marketing period of open-air grape in the north area; the second mature period is during New Year's Day and spring festival when no fruit is marketed in the north area; the period of investment return is greatly shortened; the planting benefit is doubled.

Description

technical field [0001] The invention relates to a method for planting fruits, in particular to a method for planting first crops of grapes twice a year in a northern solar greenhouse. Background technique [0002] Grape is a woody vine of the genus Vitis vinifera, with cylindrical branchlets, longitudinal ribs, glabrous or sparsely pilose, oval leaves, dense or scattered panicles, well-developed base branches, spherical or oval fruit, flowering period April-May, fruiting period August-September. Grapes have high nutritional value, but due to the northern climate, grapes are ripened once a year, with little return and low planting benefits. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for planting two crops of grapes in a northern solar greenhouse. [0004] In order to solve the above-mentioned technical problems, the technical solution of the present invention is: a method for planting grape stubble...
