Sapphire grapes are very popular fruits in recent years. Its market price is much more expensive than other varieties of grapes, which can be said to be first-class grapes. Sapphire grape is not only high in yield, easy to grow, but also good in taste. Because of this, it attracts a large number of growers to plant, but in order to obtain higher economic benefits, we must first increase its output. So, how can we increase the yield of sapphire grapes? Let's see.

rational close planting

When planting sapphire grapes, it is necessary to make rational use of land resources, at the same time, ensure sufficient illumination and good ventilation in the field, reduce the occurrence of some diseases and pests, and facilitate the later field work. The best planting density group is about 70cm between plants and row spacing1.2-1.5m.

scaffold

In order to have high-yield sapphire grapes, the construction of the frame is essential. Generally speaking, grapes rarely crawl on the ground, which not only wastes land resources, but also is prone to diseases, poor air permeability and low seed setting rate. Therefore, what we see is the growth mode of the lattice. Generally speaking, when sapphire grape seedlings grow to one meter high, we need to prepare scaffolding. Each grape is supported by a main bracket, and then connected with a rope or iron wire at the top of each bracket. Finally, the sapphire vine was pulled to the scaffold to crawl and grow. The main purpose of scaffolding is to improve the air permeability in the field, reduce the harm of pests and diseases, and improve the flowering and fruit setting rate.

Dressing and shaping

During the growth of sapphire grapes, branches and leaves should be pruned frequently to inhibit growth, promote tree growth and maintain tree shape to ensure the yield of sapphire grapes. For sapphire seedlings, we need topping and coring to promote the growth of multiple branches. Adult sapphire fruit trees should prune some branches and leaves of diseases and insect pests that are old, weak and bear little fruit. At the same time, it is necessary to inhibit the growth of branches and reduce the loss of nutrients.

blossom and fruit thinning

In order to ensure the yield and quality of sapphire grapes, attention should be paid to scientific thinning of flowers and fruits during flowering and fruit setting. In the flowering period of sapphire grapes, it is necessary to avoid serious blooming, so it is necessary to cut off or pick off some grapes that are not growing well and keep some vigorous ones. Generally, there should not be too many spikes on a branch when grapes are in panicle, otherwise it is easy to cause abnormal fruit or fruit drop due to insufficient nutrient supply, and the full or abnormal spikes should be cut off.

Scientific water and fertilizer

The growth of sapphire grapes needs more water and fertilizer. If you want sapphire grapes to grow well and have high yield, then watering and fertilizing are very critical steps. Under normal planting conditions, if there is no rain, water should be added every other week or so, which can promote the growth of sapphire grapes. Secondly, it is best to supplement fertilizer properly every time watering, mainly ternary compound fertilizer. Especially in the flowering and fruiting period of sapphire grape, its water demand and fertilizer demand are very large, so fertilization and watering should be carried out according to its specific conditions.

The above is the method I introduced to you today to improve the yield of sapphire grapes; These methods are basically connected, and each step should be done properly, so that sapphire grapes can grow better.
