The Latest Methods to Increase the Yield of Sapphire Grapes

Sapphire grapes can be said to be a very hot-selling fruit in recent years. Their market price is basically much higher than that of other grape varieties, so they can be called the finest among grapes. Sapphire grapes not only have high yields and are easy to grow, but they also taste very good. And precisely because of this, they have attracted a large number of growers to cultivate them, but to achieve high economic returns, the first thing needed is to increase their yield. So how can we increase the yield of sapphire grapes? Let's take a look below.

1. Reasonable close planting

When planting sapphire grapes, we need to make reasonable use of land resources, while also ensuring sufficient sunlight in the field and good ventilation, which can reduce the occurrence of some pests and diseases and make later field operations easier. The planting density is best controlled at a plant spacing of about 70 cm and a row spacing of about 1.2 to 1.5 m.

2. Building trellises

If we want a high yield of sapphire grapes, then building trellises is indispensable. We rarely see grapes growing by crawling on the ground, because that wastes land resources, is prone to disease, has poor ventilation, and also has a low fruit-setting rate, so what we see is the trellis-style growth method. Generally, when sapphire grape seedlings grow to 1 m tall, we need to prepare to build the supports. Each grapevine has a main support beneath it, and then the tops of each support are connected with ropes or wire. Finally, the sapphire vines are guided onto the supports to climb and grow. The main purpose of building supports is to improve field ventilation, reduce the harm of pests and diseases, and increase its flowering amount and fruit-setting rate.

3. Pruning and shaping

During the growth of sapphire grapes, we should frequently prune branches and leaves, suppress growth, promote tree vigor, and maintain tree shape to ensure the yield of sapphire grapes. For sapphire seedlings, we need to pinch off the tops to promote the growth of more branches. For adult sapphire fruit trees, however, it is necessary to prune away some branches and leaves that have aged, have weak growth, bear few fruits, or have pests and diseases, and at the same time also suppress the growth of excessively vigorous branches to reduce nutrient loss, etc.

4. Flower and fruit thinning

To ensure the yield and quality of sapphire grapes, we should pay attention to scientific flower and fruit thinning during its full flowering and fruit-setting stages. During the full flowering stage of sapphire grapes, we should avoid a serious phenomenon of flower drop, so we need to knock off or pick off some poorly growing grape flower clusters and retain some vigorous flower clusters. After the grapes set fruit and form fruit clusters, generally there should not be too many fruit clusters on one branch, otherwise it is easy for insufficient nutrient supply to cause deformed fruit or fruit drop, so we should cut off fruit clusters that are too densely grown or deformed.

5. Scientific water and fertilizer

The growth of sapphire grapes has relatively large demands for water and fertilizer. If we want sapphire grapes to grow well and achieve a high yield, then watering and fertilizing are very key steps. Under normal planting conditions, if there is no rainfall, water about once every week, which can promote the growth of sapphire grapes. Second, when watering each time, it is best to supplement fertilizer appropriately, generally mainly with a three-element compound fertilizer. Especially during the flowering and fruiting stages of sapphire grapes, their water and fertilizer demands are very large, so we should topdress and water according to their specific conditions.

The above are several methods that the editor wants to introduce to you today for increasing the yield of sapphire grapes; and these methods are basically linked together, and every step must be done well so that sapphire grapes can grow better.
