What should we do if the latest grape inflorescence is small?

The quality and number of inflorescences of grapes directly affect the late yield and quality of grapes, many orchards generally appear the phenomenon of few inflorescences, small inflorescences, especially to promote early cultivation of fruit trees, and even the problem of no inflorescence. So what caused it? How to solve and remedy it? Let's take a look at it with the editor.

First, reasons

1. Lighting reasons

Light has a great effect on the flower bud differentiation of grapes, which can be divided into long days and short days. If the density of grape branches is too high, it will lead to less inflorescence or no inflorescence in the second year because of lack of daylighting.

2. Nutrient reasons

Grape overlap in flower bud differentiation, new growth period, flowering and fruit setting stage and fruit expansion period, and these periods all need to consume a lot of nutrients, if shoot growth and fruit development are dominant in nutrient competition, while flower bud differentiation and inflorescence are at a disadvantage, it will lead to malnutrition of winter duck and affect flower bud differentiation, so inflorescence is less.

3. Orchard management

No or insufficient application of base fertilizer, excessive fruit hanging of fruit trees, excessive use of nitrogen fertilizer, neglect of organic fertilizer, and adverse control of diseases and insect pests will lead to insufficient nutrient reserves, large digestion of nutrients and difficulties in absorbing nutrients by roots. will cause fruit tree inflorescence atrophy, degradation, and even no inflorescence in the second year, a large number of new shoots.

4. Wipe the bud prematurely

In greenhouse cultivation, if the greenhouse is closed in advance, it will lead to insufficient cold capacity of grapes in flower bud differentiation, affecting flower bud differentiation, or wiping buds to break sleep too early, resulting in freezing damage to flower buds to inflorescence stage and damage to newborn parts.

II. Remedial measures

For the fruit trees with few sprouts and inflorescences, it is necessary to replenish them in time. 5 kg of balanced water-soluble fertilizer can be applied in the roots, combined with biological stimulants, through the absorptive capacity of the roots and foliar spraying at the same time, which can make the fruit trees replenish nutrition quickly and improve the tree strength as soon as possible. When more than 10 leaves are grown from the new shoots, coring measures can be taken to inhibit the vegetative growth of fruit trees and retain the two secondary shoots of summer buds under the heart, so as to delay winter bud germination and promote inflorescence differentiation. For the spring shoot without inflorescence, it can pick the heart and top in advance, and reasonably increase the application of organic fertilizer and trace elements to promote the spring shoot to mature until the secondary shoot germinates, use the secondary shoot to form inflorescence and cultivate the second batch of flowers and fruits.

The above is the introduction of how to do the small inflorescence of grapes. I hope it can help you. If you want to know more about it, please follow us.
