Problems solved by technology

However, there is a significant difference in the organic acid content of summer and winter grapes cultivated with two harvests per year and two generations of different hall models. The total organic acid content of winter fruit is significantly higher than that of summer fruit at the ripening stage of grape fruit, and winter fruit is more sour and tastes better. The quality of the grapes is poor, seriously affecting the quality of the grapes. Since the soil in Guangxi is mostly red loam, the soil is slightly acidic, and the general pH value is 5.0-6.0. The organic acid content of harvested grape winter fruit is a scientific problem in grape winter fruit cultivation

Embodiment 1

[0028] Adopt following steps to cultivate grape winter fruit:

[0029] (1) Pruning: on August 10 of each year, the fruiting branch is pruned, and each fruiting branch stays 8 buds during pruning;

[0030] (2) Accelerating germination: after pruning, use 1.5% cyanamide to wet the cut buds for budding. After budding, water the roots of the grapes with water. 1 day after budding, when the relative humidity of the air is lower than 30%, spray the grape branches with clear water to ensure that the relative humidity of the air is 40%, remove all the leaves of the fruiting branches after 4 days of budding, and let the fruiting branches dry bud;

[0031] (3) Wiping buds: After germination, wipe off the weak buds, vigorous buds, adventitious buds and over-dense buds in double buds and multi-buds;

[0032] (4) Pinching: After wiping the buds, when the fruiting branch grows to 7 leaves, pinching begins. The pinching method is to keep 2 leaves for the top auxiliary shoots, and at the sa...

Embodiment 2

[0037] Adopt following steps to cultivate grape winter fruit:

[0038] (1) Pruning: on August 30 of each year, the fruiting branch is pruned, and each fruiting branch stays 10 buds during pruning;

[0039] (2) Germination: After pruning, use cyanamide with a mass concentration of 2.5% to wet the cut buds for budding. After budding, water the roots of the grapes with water. 1 day after budding, when the relative humidity of the air is lower than 30%, spray the grape branches with clear water to ensure that the relative humidity of the air is 50%, remove all the leaves of the fruiting branches after 5 days of budding, and let the fruiting branches dry bud;

[0040] (3) Wiping buds: After germination, wipe off the weak buds, vigorous buds, adventitious buds and over-dense buds in double buds and multi-buds;

[0041] (4) Topping: After the buds are wiped, when the fruiting branches grow to 9 leaves, the topping method is to keep 2 leaves on the top auxiliary shoots, and at the s...

Embodiment 3

[0046] Adopt following steps to cultivate grape winter fruit:

[0047] (1) Pruning: Prune fruiting branches on August 20 every year, and leave 9 buds for each fruiting branch during pruning;

[0048] (2) Accelerating germination: after pruning, use cyanamide with a mass concentration of 2% to wet the cut buds for budding, and then water the roots of the grapes with clear water after the budding. 1 day after budding, when the relative humidity of the air is lower than 30%, spray the grape branches with clear water to ensure that the relative humidity of the air is 45%, remove all the leaves of the fruiting branches after 4 days of budding, and let the fruiting branches dry bud;

[0049] (3) Wiping buds: After germination, wipe off the weak buds, vigorous buds, adventitious buds and over-dense buds in double buds and multi-buds;

[0050] (4) Topping: after the buds are wiped, when the fruiting branch grows to 8 leaves, the topping method is to keep 2 leaves on the top auxiliar...

Abstract

The invention relates to the grape cultivating technology field, and especially relates to a cultivating method reducing the content of organic acids in winter fruits of grapes. The cultivating method comprises the following steps: (1) pruning; (2) accelerating germination; (3) erasing redundant buds; (4) pinching; (5) managing flowers and fruits; (6) and managing fertilization. After flowering 6-10 weeks, temperature control, light supplement by energy-saving lamps, strict control over the proportion of leaves to fruits of grapes, and other flower and fruit management measures are adopted to promote catabolism of organic acids and reduce the frequency of transport of organic acid synthesized substrates.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of grape cultivation, in particular to a cultivation method for reducing the organic acid content of grape winter fruit. [0003] 【Background technique】 [0004] Organic acid is one of the important components of the internal quality of grape fruit, which directly affects the taste of grape fruit and the recognition of consumers. my country has successfully applied the two-harvest cultivation technology in viticulture, and can produce two or more fruits a year. , especially in Guangxi, due to the mild climate, two-year grape production has become more and more common. Among them, Kyoho in Guangxi is a typical representative of the two-year grape cultivation model. However, there is a significant difference in the organic acid content of summer and winter grapes cultivated with two harvests per year and two generations of different hall models. The total organic acid content of winter fruit is signific...
