When is the suitable fertilization time for grapes?

The application of base fertilizer is generally carried out before the second growth peak of grape root system, which is 9 ~ 10 in the north and 6 ~10 ~10 in the south. At this time, fertilization is beneficial to root injury, promoting new roots and increasing nutrient storage of trees.

Introduction:

Grape is a kind of berry and one of the oldest and most widely distributed fruits in the world. Humans began to cultivate this fruit tree a long time ago. Berries are mostly round or oval, and the color varies with varieties. Almost a quarter of the world's fruit production; It has high nutritional value and can be made into grape juice, raisins and wine.

In addition, it can also be used as decoration. Grape is called "crystal pearl" because of its bright color, delicious taste and high nutritional value.

Climatic factors:

It is one of the main indexes of grape variety zoning. The French believe that only grapes planted in specific soil can produce world famous wines with unique flavor. However, for the vast grape producing areas in the world, this situation of dividing grape regions by soil is not universal and absolute. The factors affecting grape quality and wine quality are comprehensive. Only in most cases, climate often plays a leading role in the growth of grapes and the quality of wine, and climate has become the most important and active factor among many factors. Meteorological conditions such as illumination, measurement and precipitation are all necessary conditions for grape growth and fruiting, especially in summer and autumn.
