Problems solved by technology

However, when the topping treatment is carried out before flowering, the branches and tendrils tend to grow too long, the base leaves are small and stunted, and when the summer high temperature season comes, the base leaves often yellow and fall off early, and cause the base winter buds to not develop well, affecting the first stage. Two-year spike quality

Embodiment Construction

[0010] Below in conjunction with embodiment the present invention is further described in detail.

[0011] A kind of method of elongating grape flower panicle of the present invention and alleviating fruit thinning labor cost is characterized in that: described method is to take the measure of unifying topping when the length of new shoot of Kyoho grape reaches 30-40cm long, i.e. 15 days before flowering, every Only one flower spike is reserved for each new shoot, and the topping position is located at the first node on the bottommost flower spike at the base of each new shoot, that is, only one leaf is reserved on the flower spike for topping, so that the node of the node can be pinched. The secondary shoots grow longer in the next step to make up for the subsequent functional leaves.

[0012] After early topping and heavy topping, the following three aspects have been produced before flowering:

[0013] One is to carry out heavy topping early so that the growth of new shoot...

Abstract

The invention discloses a lengthening method for grape flower to reduce labor cost of fruit thinning. Pinching is carried out when a shoot of a kyoho grape grows to 30-40 cm long, that is, 15 day before the flowering. Only one spica is left and the position of pinching is located at a first node of the lowest spica of the bottom of each shoot, that is, pinching is carried out with only one leaf is left above the spica. Compared with the prior art, the lengthening method for grape flower to reduce labor cost of fruit thinning has the advantages in that firstly, pinching earlier slows the growth speed of the shoot; secondly, a vertical and lateral growth of spica is promoted effectively, and the spica is lengthened significantly; thirdly, basal leaves are increased significantly.

Description

technical field [0001] The invention relates to a planting method, in particular to a method for elongating grape flower spikes and reducing fruit thinning labor costs. Background technique [0002] Before flowering, Kyoho grapes generally adopt the method of topping to promote the next flower panicle development and preserve flowers and fruits. The specific method is to see the first flower in the vineyard, which is also called "reporting" by farmers. Keep 6-8 leaves on the flower spikes for unified topping, so that the center of gravity of the plant's vegetative growth can be quickly transferred to the flower spike development, thereby helping to alleviate the contradiction between shoots and fruits, and promote the growth of flower spikes and fruit setting in the next step. However, when the topping treatment is carried out before flowering, the branches and tendrils tend to grow too long, the base leaves are small and stunted, and when the summer high temperature season ...
