Ridging and cold protection technology of sapphire grape

Sapphire grape planting technology is different from ordinary grapes, there are certain technical requirements. When planting sapphire grapes, we should pay attention to the management of flowering and fruit period, pruning and pruning and so on. Especially in winter, we also need to do a good job of cold prevention, sapphire grapes are mainly ridged cultivation. Why ridges? How to protect against the cold? The following editor brings you the ridging and cold protection technology of sapphire grapes, let's have a look!

1. Why ridges

Root cause

The roots of sapphire grapes grow obliquely downward, and if planted in low-lying areas, the capillary roots will be too deep. If the distribution is too deep, the soil fertility is insufficient, the permeability is poor and the ground temperature rises slowly. Especially when planting in the greenhouse, the temperature in winter and spring is very low. It will have a great impact on the emergence of new roots, and the sprouting, flowering and fruiting of the aboveground parts of the plant all need a lot of nutrients. Lead to the imbalance of plant growth, reduce the fruit setting rate, fruit quality will also be greatly affected, the decline of tree potential, quality, reduce the life of the tree and so on.

Water and fertilizer absorption

The water absorption of sapphire grape is mainly capillary root, and the capillary root is mainly between rows. Therefore, fertilization should be applied between the rows in order to maximize the use of fertilizer, and the capillary roots between the rows will continue to produce new roots, and the life of the new roots is longer. If it is not ridged and planted in low-lying areas, it is not only not conducive to ditching and fertilization, but also does not get nutrition in the areas that need the most fertilizer. And the root that needs to be cut off can not be broken, which seriously affects its growth.

Not easy to manage

If the ridges are not planted in low-lying areas, and the ridges are between the rows, it is very disadvantageous to the planting management. And when planting sapphire grapes, mechanized management and harvesting are needed. If there is no ridge cultivation, then it is completely impossible to carry out mechanized production. And the drainage capacity of low-lying areas is very poor, if you do not pay attention to management, it is extremely prone to flooding, especially in those places with more rainy days. Therefore, we must make ridges when growing sapphire grapes.

2. Cold-proof technology

The cold protection of sapphire grapes is mainly carried out in extremely cold areas such as the north. If the winter temperature is not very low, just bury the base of the main vine. If the temperature is extremely cold, then we must do a good job of burying the soil, after winter cutting after the fallen leaves of the grapes, the branches will crawl on the ground. Then dig the soil deeply, apply the base fertilizer, dig the soil in the ditch, and bury the branches in the soil. Pour enough frozen water and then dig up the soil after thawing for half a month or so in spring. The time to pick the soil should not be too early, easy to freeze, and it should not be too late, otherwise it is easy to hurt the branches and buds, causing injuries and other phenomena.

The above is a brief introduction to the ridging and cold protection technology of sapphire grapes. Ridging against cold is very important for the growth of sapphire grapes, we must pay more attention. That's all for today's introduction. This article is for reference only.
