How to do the ridge cultivation and cold protection for Sapphire grapes
A small knowledge of experience, introducing you to the knowledge of ridge cultivation and cold protection for Sapphire grapes in the field of green plants and flowers. Let's learn about it together.
How to do the ridge cultivation and cold protection for Sapphire grapes
The planting technique of Sapphire grapes is different from that of ordinary grapes, so there are certain requirements for planting techniques. When planting Sapphire grapes, attention should be paid to the management of flowering and fruiting periods, pruning, etc. Especially in winter, we need to do a good job of cold protection. Ridge cultivation is the main cold protection measure for Sapphire grapes. Why ridge? How to prevent colds? The following is the ridge cultivation and cold protection technology for Sapphire grapes brought to you by the editor. Let's take a look!
Basic reason for ridge cultivation
The roots of Sapphire grapes slope downwards. 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 soil temperature rises slowly. Especially in greenhouses, the temperature in winter and spring is very low. It will have a great impact on the root system's pumping of new roots, while the germination, flowering, and fruiting of the aboveground parts of the plant require a large amount of nutrients. As a result, the plant growth is unbalanced, the fruit-setting rate is reduced, and the fruit quality is also greatly affected, such as the decline of tree vitality, quality, and lifespan.
Water and fertilizer absorption
The water absorption of Sapphire grapes mainly depends on capillary roots, which are mainly distributed between rows. Therefore, fertilization should be done between rows to maximize fertilizer utilization. The capillary roots between rows will continuously develop new roots, which have a relatively long lifespan. If ridge cultivation is not carried out in low-lying areas, it is not conducive to furrow fertilization, and the area that requires the most fertilizer cannot obtain nutrients. Moreover, the roots that need to be broken cannot be broken, which seriously affects their growth.
Difficult to manage
If ridge cultivation is not carried out in low-lying areas and the ridges are between rows, it is very disadvantageous for planting management. When planting Sapphire grapes, mechanized management and harvesting should be implemented. If ridge cultivation is not carried out, it is completely impossible to carry out mechanized production. Moreover, the drainage capacity of low-lying areas is poor. If we do not pay attention to management, it is easy to cause flooding, especially in rainy areas. Therefore, ridge cultivation must be carried out when planting Sapphire grapes.
Cold protection technology
The cold protection work of Sapphire grapes is mainly carried out in extremely cold areas in the north. If the winter temperature is not very low, the roots of the main vines are buried. If the temperature is extremely low, then the burial work should be done well. After the grape leaves are cut in winter, the vines will lie on the ground. Then, dig deep into the soil, apply base fertilizer, dig the soil into the trench, and bury the branches and vines in the soil. Then pour enough frozen water and remove the soil half a month after the spring thaw. It is not advisable to dig the soil too early, as it is easy to freeze, or too late, otherwise it may damage the branches and buds, and bleeding phenomena may occur.
The above briefly introduces the ridge cultivation and cold protection technology for Sapphire grapes. Ridge cultivation is very important for the growth of Sapphire grapes and must be taken seriously. That's all for today's introduction. This article is for reference only and I hope it helps you!
