A kind of whole ear method of red Balado 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. Table grapes have become the leading industry for farmers to get rid of poverty and become rich. In order to meet the people's demand for different varieties of grapes, breeders have developed many new varieties and strains of table grapes. Red Balado grape is a high-quality table grape variety introduced from abroad in recent years. Red Balad (ベニバラード) originated in Japan and belongs to a European-Asian hybrid diploid variety. It is a new variety bred in 1997 by Takayuki Yoneyama, Kofu City, using'Balad' and my country's selected variety'Jingxiu' , Registered in 2005. Observation results for many years sho...

Problems solved by technology

[0003] The present invention aims at the high fruit setting rate of red balado grapes under natural conditions, often resulting in large ears, small fruit grains, and tight growth of ears, which often produce extrusion deformation, even crushed and mildewed in the middle of the ears, which seriously affects red balado grapes. Due to the commercial nature of many grapes, the conventional method of manually thinning flowers and fruits is time-consuming and labor-intensive, and the cost is high. This prominent problem provides a method for whole ears of red Balado grapes
