Cultivation method of wine grapes growing in Minjiang upriver region

Abstract

The invention belongs to the technical field of plant cultivation and particularly relates to a cultivation method of wine grapes growing in a Minjiang upriver region. The cultivation method of grapes in the invention comprises the following steps of: treating sublateral shoots in summer; cutting off all sublateral shoots at a fruit position and below the fruit position; leaving 3 leaves growing above the fruit position during first sublateral shoot pinching; leaving 1 leaf growing after the pinching during second sublateral shoot pinching; leaving 1 leaf during third sublateral shoot pinching; repeatedly leaving 4-5 leaves of an extending shoot at the top end of a shoot for pinching; and cutting off all sublateral shoots on the extending shoot. The invention has the advantages of increasing the yield of grape fruits and saving labor cost.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a method for cultivating wine grapes in the upper reaches of the Minjiang River. Background technique [0002] The upper reaches of the Minjiang River began to plant wine grapes on a trial basis in 1999. Due to the lack of much experience in planting vines, farmers have almost no control and pruning techniques or methods for grape branches during the planting process. Rich, very suitable for the growth of temperate fruits such as grapes. Grapes sprout in early April to stop growing in early October for up to 6 months, and the growth of auxiliary shoots is extremely large. Most farmers cut off the auxiliary shoots according to the pruning method of apples, resulting in vigorous tree vigor, fast vegetative growth, poor flower bud differentiation, low fruit setting rate, poor quality, susceptibility to diseases, loose fruit ears, etc.; at the same time, it take...

AI Technical Summary

Problems solved by technology

Most farmers cut off the auxiliary shoots according to the pruning method of apples, resulting in vigorous tree vigor, fast vegetative growth, poor flower bud differentiation, low fruit setting rate, poor quality, susceptibility to diseases, loose fruit ears, etc.; at the same time, it takes a lot of labor.

An important reason for these problems is that the growth control of the auxiliary shoots of the grapes is poor in summer. The function of the auxiliary shoots of the grapes is to increase the area of ​​the canopy and photosynthetic leaves, and help the tree to accumulate dry matter nutrients. If the control is not proper, it will not only consume a lot of nutrients , but also due to canopy closure prone to disease and insect pests causing greater losses
