Things to Note at Different Stages of Sapphire Grapes
Sapphire grapes are a new variety of grapes that differ in quality and appearance from ordinary grapes. Due to people's curiosity, they have been well-received by many since they were first introduced to the market. Therefore, more and more people are planting sapphire grapes, and the planting area is also increasing. The management method is very important when planting sapphire grapes. Each stage has different key management points. Here is a simple introduction.
Young Shoots
The growth period of young shoots usually ranges from the growth of the bud eye to the early flowering stage, with a total duration of about 35 days. When the average daily temperature is above 10℃, the buds of sapphire grapes will start to sprout. About half a month later, the growth rate of young shoots will accelerate, entering the full bloom 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 necessary 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 flowering to the last flowering being only 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 period, appropriate application of fertilizers such as fulvic acid should be made to improve fertilization and fruit setting rates. During the flowering period, 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 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 to supplement trace elements such as calcium and boron in time. In addition, foliar fertilizers should be sprayed appropriately to enhance the photosynthetic effect of leaves, increase nutrient accumulation, promote fruit expansion, and improve berry quality.
The above briefly introduces the key management points at different stages of sapphire grapes. The management of sapphire grapes is very important, as good or bad management directly affects yield, so special attention must be paid.
