How to Control the Excessive Growth of Grapevines
Today, let's discuss the topic related to the cultivation of flowers and how to control the excessive growth of grapevines, with the following details:
How to Control the Excessive Growth of Grapevines
Many people have heard the term "excessive growth of grapes." So, what should we do about it? Here are some related pieces of information that we can all take a look at together.
Signs of Excessive Growth
First, we need to determine whether our grapevines are indeed growing excessively. Excessively growing grapevines typically have the following characteristics. You can judge based on the article and your own grapevine growth. Excessive growth may manifest as overly long branches, numerous lateral buds, and late sprouting. Due to the excessive growth, new shoots cannot store nutrients, leading to insufficient supply for flower bud differentiation, which can cause blossom and fruit drop, a decrease in fruit sugar content, uneven coloring, and reduced quality.
Causes of Excessive Growth in Grapevines
1. Physiological defects: Related to the inherent characteristics of the variety, such as abnormal ovule development, imperfect pistil or stamen development, or some sterile pollen, resulting in a low fruit-setting rate.
2. Abnormal climate: Grape flowering requires relatively suitable climatic conditions, with daytime temperatures between 20-28°C, minimum temperatures above 14°C, relative humidity of about 65%, and good lighting conditions. Abnormal weather conditions during flowering, such as low temperatures, rainfall, or drought, directly affect the development and growth of inflorescences, preventing the normal process of pollination and fertilization from being completed, leading to a low fruit-setting rate.
3. Insufficient nutrient storage in the tree: The nutrients required by grapevines during flowering are mainly supplied by the nutrients stored in the stems and roots. If the previous year's yield was too high or there was severe pest and disease damage, causing poor shoot maturation or premature defoliation, the tree's nutrient storage would be insufficient. This could lead to weak new shoot growth, poor differentiation of the original inflorescence bodies, and underdeveloped flower organs, resulting in significant blossom and fruit drop after flowering and a low fruit-setting rate.
Why Do Vines Grow Vigorously?
This may be related to the variety. If the ovules in this number develop abnormally or the stamens are not fully developed, pollen pollination will be affected, and the number of fruits will decrease. This could also be due to the influence of climate. Generally speaking, when grapes are flowering, they need appropriate conditions to support their continued flowering. For example, the daytime temperature needs to reach 25 degrees, the nighttime temperature needs to exceed 14 degrees, the air humidity should not be too low, and there should be good light intensity.
