Problems solved by technology

However, in areas where the annual average temperature is lower than 20°C, when two generations of grapes are cultivated in different halls with no overlapping growth of primary and secondary fruits, the temperature will drop rapidly after October, which cannot meet the needs of secondary fruit cultivation. The accumulated temperature required for growth and maturity, therefore, can only adopt the two-generation co-cultivation mode in which the first and second fruits overlap and grow

Embodiment Construction

[0024] The present invention will be further described below with specific examples, but the present invention is not limited to these examples.

[0025] The experimental garden is located in the ×× Xiahei Vineyard of Liantang Village Committee, Rongjiang Town, Xing'an County, Guilin City, Guangxi.

[0026] The garden was built in March 2010, with a plant spacing of 1.2 meters, a row spacing of 2.3 meters, and an area of ​​1 mu. Rain shelter cultivation, the rain shelter is 2 meters high and 1.8 meters wide. After the grape seedlings were planted in 2010 and 2011, they were managed by conventional cultivation techniques.

[0027] In the spring of 2012, 1 mu of experimental field is divided into two experimental areas, each experimental area has an area of ​​0.5 mu, and is respectively numbered as 1# experimental area and 2# experimental area, wherein 1# experimental area is managed by the cultivation method described in the present invention , The 2# experimental area is man...

Abstract

The invention discloses a grape double cropping cultivation method comprising the following steps: (1) fruiting mother branches are subjected to winter pruning; (2) first-crop fruits are managed with an existing regular cultivation management method, and first-crop fruit yield per mu is controlled at 1250-1500kg; (3) when the first-crop fruits are harvested, green branches with leaves are pruned in time, such that second-crop bloom is promoted, and second-crop fruits can be cultivated. According to the method provided by the invention, the green branches with leaves are pruned in time after the first-crop fruits are harvested, such that second-crop bloom is promoted and second-crop fruits can be formed. On the one hand, overlapping growth of the first-crop and second-crop fruits is avoided, such that interference between the growth of the first-crop and second-crop is prevented. Therefore, first-crop fruits coloring and mature can be promoted, and second-crop fruits management can be facilitated, such that production efficiency can be improved. One the other hand, with the cultivation method provided by the invention, because pruning and the promotion of second-crop blooming are performed in advance, a late-maturing variety can also be subjected to double-cropping cultivation with a mode that two generations are not in a single branch. Therefore, selections of grape double-cropping varieties are enriched.

Description

technical field [0001] The invention relates to a method for cultivating grapes, in particular to a method for cultivating grapes with two harvests a year. Background technique [0002] Grapes are one of the main fruits in our country. Conventional viticulture only bears fruit once a year and harvests once. In recent years, in order to adjust the market supply of grapes in the off-season, meet the market demand, and increase the income of fruit farmers, the two-harvest grape cultivation technology has been widely used in southern my country. [0003] Currently, there are two types of cultivation methods for grapes that are harvested twice a year. One is the two-generation cultivation mode in which the first and second fruits overlap and grow together. Secondary flowers form secondary fruit; in a period, primary fruit and secondary fruit hang on the tree and grow at the same time. The other is the two-generation different cultivation mode in which the first and second frui...
