Methods for Different Stages of Sapphire Grapes
Sapphire grapes are a variety of grapes. The flesh is rich in juice and seedless. They taste sweet and crunchy with a delicious flavor. Due to their unique texture, sapphire grapes are very popular in the market, and thus, more and more farmers have been planting sapphire grapes in recent years. To have a high yield of sapphire grapes, management at each stage is very important. This article briefly introduces the key points of management for sapphire grapes at different stages.
Bleeding Stage
Every spring, when the soil temperature rises to 7-8 degrees, the grape roots gradually recover and start absorbing (S-Y) parts. Then, the nutrients are transported to the above-ground part of the plant, promoting the germination of grapes. However, due to the thick and loose vessels of the sapphire grape vines, when the sap activity is strong, sap will flow out from any wounds on the plant. This is the bleeding stage of sapphire grapes. Therefore, during the bleeding stage, it is essential to strengthen management, prevent wounds on the trees, avoid pruning as much as possible, and properly loosen the soil and remove weeds to prevent bleeding.
Shoot Growth Stage
The growth period of new shoots usually lasts from the bud growth to the early flowering stage, with a total time of about 35 days. When the average daily temperature is above 10℃, the buds of sapphire grapes will start to germinate. About half a month later, the growth rate of new shoots will accelerate and enter the full flowering stage. At this time, the organs and parts of sapphire grapes are in a period of vigorous growth, which is related to the yield of the year. Therefore, it is necessary to do a good job of fertilization, controlling the ratio of nitrogen, phosphorus, and potassium. To prevent excessive nutrient intake, it is important to do a good job of fixing buds and removing buds, and adjust the grape load reasonably.
Flowering Stage
The flowering period of sapphire grapes is relatively short, with the longest time from the first to the last flowering being about half a month. When the temperature rises to about 25 degrees, this is the optimal temperature for sapphire grapes to bloom. If the temperature is lower than 15℃, it will reduce the fertilization rate. Therefore, during the flowering stage, fertilizers such as fulvic acid should be applied appropriately to improve fertilization and fruit setting rates. And during the flowering stage, we should do a good job of binding vines and removing shoots. To improve field ventilation and promote flowering, artificial pollination should be carried out for some flowers with poor pollination effects.
Berry Growth Stage
When the flesh chamber of the grape begins to expand, it enters the berry growth stage of sapphire grapes. Until the berries become soft. During this period, sapphire grapes require a lot of nutrients, so the proportion of nutrients should be increased. It is not only necessary to increase the basic nutrients such as nitrogen, phosphorus, and potassium but also supplement trace elements such as calcium and boron in time. In addition, foliar fertilizers should be sprayed appropriately to enhance the photosynthesis of leaves, increase nutrient accumulation, promote fruit expansion, and improve berry quality.
The above are the key points of management for sapphire grapes at different stages. The conditions for planting sapphire grapes are very strict, so if farmers want to grow sapphire grapes well, they must master the management points of the above stages to achieve high yields.
The comprehensive method explanation of the methods for different stages of sapphire grapes introduced above can hopefully act as a catalyst to solve your problems in green plants.
