Embodiment 1

[0021] Grapes of the Kyoho variety are used for cultivation, and the planting arrangement is to arrange vines in alternating large and small rows. The spacing between small rows is controlled at 0.4-0.6m, and the spacing between large rows is controlled at 2.5-3m. Prune the grapes in the middle and late January, so that the trunk and main vines of the vines are arranged in a T-shape on the V-shaped double-hedge frame. When the temperature is stable above 10°C in late February, use 50% cyanamide 15 times solution Wet the bud eyes to break the dormancy and accelerate the germination. After the germination treatment, tie the main branches grown on the same main vine to the grape trellis to form the first V-shaped arrangement. Ripening and flower bud differentiation, 1 week before flowering (around April 18), pluck the main shoot with 4 to 5 leaves above the flower. After the main shoot is pinched, only one auxiliary shoot is left on the top of the fruiting branch, and the rest are...

Embodiment 2

[0025] Grapes of the Jingya variety are used for cultivation, and the planting arrangement is to arrange vines in alternating large and small rows. The spacing between small rows is controlled at 0.4-0.6m, and the spacing between large rows is controlled at 2.5-3m. Prune the grapes in the middle and late January, so that the trunk and main vines of the vines are arranged in a T-shape on the V-shaped double-hedge frame. Wet the bud eyes to break sleep and accelerate germination. After the germination treatment, tie the main branches grown on the same main vine to the grape trellis to form the first V-shaped arrangement. Ripening and flower bud differentiation, one week before flowering (around April 23), the main shoot leaves 4-5 leaves above the flower for pinching, after the main shoot pinching, only one auxiliary shoot is left on the top of the fruiting branch, and the rest are erased, 5 Bloom at the beginning of the month, and apply the first mixed fertilizer after the firs...

Abstract

The invention discloses a cultivation method of harvesting south grapes twice a year. The cultivation method comprises the following specific operations of trimming the grapes in mid-to-late January, carrying out bud forcing treatment when the temperature is stabilized to be more than 10 DEG C in late February and mid-March, spraying a tip-control inhibitor and pinching to promote blade ageing and flower bud differentiation, blooming in April and May, applying a first compound fertilizer after first fruits are fully matured; trimming the grapes in June and July to force winter buds to germinate, harvesting the first fruits in July and August, causing branches to bloom to obtain second fruits, applying a second compound fertilizer, and harvesting the second fruits in October and November. Through the scheme, the grapes can be harvested twice a year, so that the yield of the grapes is effectively improved by about 10%-20%, the fresh grape supply period is prolonged, and the economic benefit for planting the south grapes is remarkably improved.

Description

technical field [0001] The invention relates to the field of grape cultivation, in particular to a cultivation method for harvesting twice a year of southern grapes. Background technique [0002] Grape is one of the three major fruits in the world. It is rich in sugar, organic acid, protein and vitamins and other nutrients. It is a fruit suitable for all ages. It is also the raw material for various beverages, such as wine. Grapes are also seasonal fruits. Under normal circumstances, the ripening period of fresh grape fruits in southern regions ends in mid-to-late August, and in northern regions in mid-to-late October. Therefore, there is too much supply of fresh grape fruits on the market from September to November, while in other regions During the month, the supply of fresh grapes is less. In order to adjust the supply of grapes, meet the market demand, and increase the income of fruit farmers, scientific and technological personnel in the north and south of my country h...
