Cuttage Technique of Sapphire Grape

Sapphire grape is a kind of grape variety, which has a certain planting area in China after it was introduced from Australia. However, because it is a new variety, the planting time is not long, so there are still many deficiencies in the planting technology. In particular, the breeding technology of sapphire is generally based on cuttage. So how to go to cuttage exactly? The following editor brings you the cutting technology of sapphire grapes, let's have a look!

1. Pre-insertion preparation

Before cutting, we should do a good job of the soil, turn the soil deep in autumn, and then ripen the soil. Then turn deep again in March-April of the following year, then level the soil, control the row spacing and dig the planting ditch, and dig the planting ditch in the middle of the planting ditch to control the width and depth. Before planting, apply sufficient base fertilizer, add topsoil, and pour enough water. We should pay attention to ensure the quality of the soil, reduce the bacteria in the soil as much as possible, ensure the drainage and irrigation capacity of the soil, increase fertility, and create a good growth environment for sapphire grapes.

2. Cuttings selection

After we have prepared the soil before planting, we have to choose cuttings. Cuttings should choose annual branches with short internodes, moderate pith, many bud eyes and full annual branches free of diseases and insect pests. The thickness of the branches should be kept at about 0.8cm, about 5 buds should be retained, the upper part of the cuttings should be kept flat, and the cuttings should be mainly slanted. Then soak the roots with a rooting agent for a day and disinfect them. There are two cutting methods of sapphire grapes, generally mainly by hole cutting, we should pay attention to control the distance between plants, about 800 per mu.

3. Plug-in management

After cultivation, we should have a comprehensive cultivation measures to improve the survival rate and promote growth and development. It is necessary to do a good job in the prevention and control of grass famine, diseases and insect pests. After the cuttings are ripe, it is necessary to do a good job in water and fertilizer management and fully meet the water and nutrition needs of sapphire grapes. After survival, pruning should be done according to the growth of sapphire grapes. We should pay attention to control the pruning time, do not prune too early and too late, otherwise it will have a great impact on the sapphire grape, resulting in serious nutrient loss, reducing the tree potential and other adverse phenomena.

4. Points for attention

Sapphire grape must be managed well after cutting. the quality of management has a great relationship with the survival rate of cuttings. Must strictly control the amount of water and fertilizer, not too much, otherwise prone to fertilizer damage, waterlogging and other phenomena. Then it is necessary to do a good job in the prevention and control of diseases and insect pests, which is also closely related to the survival rate of sapphire grapes. We should give priority to prevention, supplemented by prevention and control, enhance the disease resistance of sapphire grapes, find out the cause in time after the disease, and then make corresponding measures.

The above is a brief introduction of sapphire grape cutting technology. The cutting of sapphire grapes is the main method of propagation, so it is very important for sapphire grapes, so we must pay more attention to it. That's all for today's introduction.
