How to Increase the Yield of Sapphire Grapes? A Detailed Guide to Practical Growing Techniques
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. 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 facilitate later field operations. 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-type growth method. Generally, when sapphire grape seedlings grow to a height of 1 m, we need to prepare to build supports. Each grape plant has a main support beneath it, and then the tops of each support are connected with ropes or wire. Finally, the sapphire grape vines are guided onto the supports to grow by climbing. The main purpose of building supports is to improve ventilation in the field, 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, 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 them to promote the growth of more branches. For adult sapphire grape 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 inhibit the growth of excessively vigorous branches to reduce nutrient loss, and so on.
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 their full bloom and fruit-setting stages. During the full bloom stage of sapphire grapes, we should avoid a serious flower drop phenomenon, 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 insufficient nutrient supply can easily 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 management
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 growing conditions, if there is no rainfall, water about once every week, which can promote the growth of sapphire grapes. Next, when watering each time, it is best to appropriately supplement fertilizer, generally mainly 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 each step must be done well so that sapphire grapes can grow better.
