What are the reasons for the uneven germination of grape buds
This article introduction: The related introduction of the reasons for the uneven germination of grape buds in green plants and flowers, let's get to know together next.
What are the reasons for the uneven germination of grape buds
Grapes are rich in nutrients, sweet and juicy, and are loved by many friends, especially grape growers in our country. However, during the grape cultivation process, irregular grape buds often appear. Irregular grape buds can affect a series of agricultural operations such as bud removal, fruit picking, fruit preservation, and fruit expansion, bringing many inconveniences to grape garden management. Some branches do not germinate directly, causing empty trees and affecting the normal production of the grape garden. So what are the reasons for irregular grape germination? How to solve it?
Reasons for Uneven Grape Germination
1. These trees are malnourished
Many growers, in pursuit of high yields, cause excessive nutrient consumption in trees, reducing stored nutrients and affecting the following year's germination. In addition, poor management after last year's harvest, inadequate pest control, early defoliation of grapes, weakened photosynthesis, nutrient accumulation, and sowing all affect germination.
2. Improper pruning
The advantage of the top of the grapevine is that it bears fruit, and the buds at the farthest point from the root are restricted in germination. If too many leaf buds are pruned from the long tender branches, the buds at the top of the branches will start to germinate first, and the later the germination time, the more uneven the germination.
3. Water deficiency
When there is sufficient water during grape germination, germination is earlier and the germination rate is higher. However, if the soil is dry and lacks water, germination is later and the germination rate is relatively lower. Last year's rainy season, if drainage was not timely, could lead to vigorous branch growth, insufficient nutrient accumulation, and irregular germination.
4. Temperature
In last year's low temperatures, if anti-freezing measures were not in place, low temperatures could cause slight frost damage to grape branches. In the spring, poor nutrient transportation affects seed germination and flowering. In addition, low temperatures can also affect the absorption capacity of the roots, thus affecting germination.
Measures to Solve Irregular Grape Germination
1. Apply base fertilizer
After grape harvest, base fertilizer should be applied in conjunction with autumn cleaning of the garden, mainly with organic and farmyard manure, which can help grapes survive the winter and provide nutrients for the plants, promoting germination the following year.
2. Timely pruning and irrigation
Dry branches should be collected in time, and branches with uneven germination, weak in front and strong in back, should be collected to a good bud and branch position, mainly to restore tree vitality. When the ground temperature rises, irrigation should be carried out in time to ensure sufficient water. After irrigation, the soil should be loosened in time to avoid soil hardening. The amount of water should not be excessive, and the soil moisture content should be maintained at 65%.
3. Use nitrogen fertilizer in the early stage and increase phosphorus and potassium fertilizer in the later stage. Additionally, foliar fertilizer can be added to promote the growth and maturity of new shoots.
The above are the reasons and solutions for irregular grape germination. The earlier the grapes germinate, the earlier they can be listed on the market. Generally speaking, there are two types of irregular grape buds. One is in the same orchard, different trees do not germinate together. Generally, the weaker the tree, the earlier the germination. The more vigorous the tree grew last year, the later the germination. The other is the same fruiting parent branch, if the number of buds is too large, the top will germinate first, and the middle and lower parts will germinate later. Growers should pay attention and solve the problem in time.
The above is the specific introduction of the reasons for the uneven germination of grape buds, hoping you will like it!
