Latest Sapphire Grape Ridging and Cold-Protection Technique Method Tutorial

Sapphire grape cultivation techniques differ from those of ordinary grapes and have certain technical requirements. When planting Sapphire grapes, attention must be paid to flower and fruit stage management, pruning and training, and other tasks. Especially in winter, we must also do a good job of cold protection. Cold protection for Sapphire grapes is mainly based on ridging cultivation. Why ridge? How should cold protection be done? Below, the editor brings you the ridging and cold-protection technique for Sapphire grapes. Let's take a look!

1. Why ridge

Root reasons

The root system of Sapphire grapes grows downward at a slant. If planted in low-lying areas, the fine roots will be distributed too deep. If distributed too deep, soil fertility is insufficient, permeability is poor, and the ground temperature rises slowly. Especially when growing in greenhouses, temperatures in seasons such as winter and spring are very low. This greatly affects the roots' production of new roots, while the aboveground part of the plant needs large amounts of nutrients for sprouting, flowering and fruiting. This leads to unbalanced plant growth, reduces the fruit-setting rate, and greatly affects fruit quality, causing tree vigor to decline, quality to decrease, and the tree's lifespan to be shortened.

Water and fertilizer absorption

Water absorption by Sapphire grapes is mainly through fine roots, and the fine roots are mainly in the rows. Therefore, when fertilizing, fertilizer should be applied in the rows to ensure maximum fertilizer utilization, and the fine roots in the rows will continuously produce new roots, and the lifespan of the new roots is also relatively long. If not planted on ridges but in low-lying areas, it is not only unfavorable for opening furrows to fertilize, but the area with the greatest fertilizer demand cannot get nutrients. Moreover, the roots that need to be cut cannot be cut, seriously affecting their growth.

Difficult to manage

If not cultivated on ridges but planted in low-lying areas, with the ridges between the rows, then it is very unfavorable for planting management work. Moreover, when planting Sapphire grapes, mechanized management and harvesting are required. If not cultivated on ridges, mechanized production is completely impossible. In addition, the drainage capacity of low-lying areas is very poor, and with even slight inattention in management, flooding is very likely to occur, especially in places with many rainy days. Therefore, when planting Sapphire grapes, we must use ridging cultivation.

2. Cold-protection technique

Cold-protection work for Sapphire grapes is mainly carried out in extremely cold northern regions and similar areas. If the winter temperature is not very low, then it is enough to bury the base of the plant's main vine well. If the temperature is extremely cold, then soil burial work must be done well. After the grapes drop their leaves and winter pruning is completed, lay the branches and vines prostrate on the ground. Then deep-plow the soil, apply base fertilizer, and then dig soil from the furrow to bury the branches and vines in the soil. Then water thoroughly with freezing water, and after the soil thaws in spring for about half a month, uncover the soil. The timing of uncovering the soil should not be too early, as it is prone to freezing injury, nor too late, otherwise it is easy to damage the branches and buds, causing bleeding and similar phenomena.

The above is a brief introduction to the ridging and cold-protection technique for Sapphire grapes. Ridging and cold protection are very important for the growth of Sapphire grapes, so everyone must pay close attention. That is all for today's introduction.
