How to increase the yield of sapphire grapes?
Sapphire grapes have been very popular in recent years. Their market price is much higher than other varieties of grapes, making them a high-end type of grape. Sapphire grapes not only have high yields and are easy to grow, but also have a good taste. Because of this, they have attracted a large number of growers to cultivate them. However, to achieve higher economic benefits, it is first necessary to increase their yield. So, how can we increase the yield of sapphire grapes? Let's take a look.
Reasonable dense planting
When planting sapphire grapes, it is important to make rational use of land resources while ensuring that there is sufficient sunlight and good ventilation in the field to reduce the occurrence of some diseases and pests and facilitate later field operations. The best planting density is a spacing of about 70cm between plants and 1.2-1.5m between rows.
Trellising
In order to have high-yielding sapphire grapes, the construction of trellises is essential. Generally, grapes do not crawl on the ground, which not only wastes land resources but also makes it prone to diseases, poor ventilation, and low fruiting rate. Therefore, we see the lattice growth method. Usually, when sapphire grape seedlings grow to about one meter high, we need to prepare a trellis. Each grape is supported by a main trellis, then strings or wires are connected at the top of each trellis. Finally, the sapphire vines are pulled onto the trellis to climb and grow. The main purpose of trellis construction is to improve field ventilation, reduce the harm of diseases and pests, and increase the flowering and fruit-setting rate.
Pruning and shaping
During the growth of sapphire grapes, it is necessary to prune the branches and leaves frequently to inhibit growth, promote tree vigor, and maintain tree shape to ensure the yield of sapphire grapes. For sapphire seedlings, we need to top and pinch the tips to promote the growth of multiple branches. For mature sapphire fruit trees, we should prune some aging, weak-growing, and disease-prone branches and leaves. At the same time, we should also inhibit the growth of dense branches to reduce nutrient loss.
Thinning flowers and fruits
In order to ensure the yield and quality of sapphire grapes, it is important to pay attention to scientific thinning of flowers and fruits during the full bloom and fruit-setting stages. During the full bloom of sapphire grapes, it is necessary to avoid severe flower drop, so some poor-quality grape clusters should be cut or removed, and some vigorous clusters should be retained. When the grapes are fruiting, there should not be too many clusters on one branch, otherwise, it is easy to cause malformed fruits or fruit drop due to insufficient nutrition. Therefore, the full or malformed clusters should be cut off.
Scientific watering and fertilizing
Sapphire grapes require a lot of water and fertilizer for growth. If you want sapphire grapes to grow well and achieve high yields, watering and fertilizing are very critical steps. Under normal planting conditions, if there is no rainfall, it is necessary to water every week or so to promote the growth of sapphire grapes. Additionally, it is best to supplement fertilizer appropriately each time you water, mainly using ternary compound fertilizers. Especially during the flowering and fruiting stage of sapphire grapes, their water and fertilizer requirements are very high, and fertilizing and watering should be carried out according to their specific conditions.
The above are several methods introduced by the editor today for increasing the yield of sapphire grapes; these methods are basically interconnected, and each step must be done properly to make sapphire grapes grow better.
