Grape branches are not round, but have vertical bars. Is there something missing?

The reason why the grape branches are not round and have vertical bars is: 1. Lack of nutrients in the early stage led to poor growth of trees. 2. Various reasons. 3. Geographical factors. Scaffolding management technology. 5. Environmental factors.

First, seedling management.

Generally, grape planting begins with seedling planting, so in order to improve the survival rate of seedlings, seedling management is very important. If the weather is dry after planting seedlings, water them reasonably according to the drought degree at that time to promote the growth of new roots. According to the growth of seedlings, reasonable topdressing can promote the growth of seedlings. It is found that the leaves of seedlings are yellow in the early stage, so topdressing should be done in time to supplement nutrition. Weeding at seedling stage is also very important, and shallow tillage is generally used to avoid damaging the root system of seedlings.

Second, the management of growth period.

Grape growth period management is definitely to promote grape growth, accelerate its flowering and fruiting, and shorten the growth cycle of grapes. During this period, the most important management technology is fertilization. Fertilization should be mainly based on nitrogen fertilizer, and phosphorus and potassium fertilizer should also be used in combination. If the soil lacks trace elements, Trim microbial fertilizer should be supplemented. The most important thing in this period is to build a grape trellis and pull the vines onto the scaffolding to improve the permeability of the field and promote the growth of lateral branches.

Third, the management of grade period.

In the germination stage of spring, topdressing should be done once, with nitrogen fertilizer as the main fertilizer and phosphorus and potassium fertilizer as the auxiliary fertilizer, which can promote the growth and germination of grape branches. Topdressing once when grapes bloom, mainly using phosphorus and potassium fertilizer once to protect flowers and fruits. At this time, we also need to do a job of thinning flowers and fruits, which is also to improve the yield and quality of grapes. When the grape fruit grows to the size of soybean, it is topdressing once, mainly foliar fertilizer, and borax is usually used to strengthen the fruit.
