Spike pruning method for Benibalad grape

Abstract

The invention discloses a spike pruning method for Benibalad grape. Watering is carried out once in the early stage of grape blooming, namely 0%-30% of the grape blooms, and the water quantity of 35-40 kg; the flower spike is trimmed after the full-bloom stage, namely 70-80% of the grape blooms, an auxiliary spike, and three to five branches on the upper part of the spike shoulder are trimmed, a spike tip is not trimmed, and twenty to twenty-three branches of the whole flower spike are kept. After the flower spike is trimmed, the width of the spike shoulder is maintained, the width of the spike tail is 3-4.5 cm, and the length of the spike is 11-13 cm. Through quantitative watering and timely flower spike trimming, the distribution of plant hormones in the spike is regulated, the hypogenetic inflorescence of grape variety with high natural fruit setting rate is enabled to realize bloom dropping and bud falling, the flower thinning effect is realized, the competing for nutrients in the blooming process of the flower buds is reduced, the size of the grape spike is controlled, the fruit size is increased, the workload of fruit thinning is reduced, and the fruit quality is improved.

Description

technical field

[0001] The invention relates to a method for whole ears of red Balado grapes, which belongs to fruit tree cultivation technology, and is especially suitable for the cultivation of grape varieties with high natural fruit setting rate. Background technique

[0002] With the continuous improvement of people's living standards, the demand for grapes is increasing, and fresh grapes have become the leading industry for farmers to get rid of poverty and become rich. In order to meet people's needs for different varieties of grapes, breeders have bred many new varieties and lines of table grapes. Red Balado grape is a high-quality table grape variety introduced from abroad in recent years. Red Balado (ベニバラード) is native to Japan and belongs to the Eurasian hybrid diploid variety. It is a new variety bred by Takayuki Yoneyama in Kofu City, Japan in 1997 by crossing 'Balad' and the variety 'Jingxiu' bred in my country. , registered in 2005. Years of observations have ...

Examples

specific Embodiment

[0017] Selected varieties: 4-year-old red Balado grapes.

[0018] Rain-shelter cultivation is adopted, the planting distance between plants is 4m×3m, the frame type is a single cross fence frame, and the tree shape is "flying bird" shape, that is, a wire cable is drawn along the row at the top of the fence column 30cm down, and the upper part The pull wires together form the "flying bird" type frame surface. Cultivate two main branches left and right along the bottom iron wire, V-shaped leaf curtain, medium tree vigor, equipped with drip irrigation facilities, good management level, and routine management in the field. When pruning in winter, the fruiting mother branches are separated by 20-30cm on both sides of the hedge, and the fruiting mother branches are left with 2 buds and cut short. After the next year's germination, when the new shoot grows to about 40-50cm, choose a moderate fruiting branch , lure the new shoots to both sides of the "V"-shaped fence, and wipe off al...
