Planting techniques of Ice Grape

Ice grape is a new type of grape variety, which can be retained on the tree for a long time even if it is not harvested after the fruit is ripe. The harvest time can be delayed by about one month. Now ice grapes can not only be eaten raw, but also the main raw material of ice wine. The brewed grapes have a mellow taste and good quality, and are liked by many people. So how to grow ice grapes? The following editor brings you the planting technology of ice grapes, let's have a look!

1. Select seedlings to build a garden

The lateral root of ice grape seedlings should be kept above 7, the length should not be less than 18 cm, and there are more fibrous roots. Then do a good job of soil preparation before planting, control the planting density and dig the planting ditch. The depth and width of the planting ditch should be controlled at about 50 to 50 centimeters. Then apply sufficient base fertilizer, the base fertilizer is mainly farm manure. If the soil moisture conservation capacity is not strong, then watering in the planting process should be watered thoroughly and step on the soil. Ridging about 12 cm, covering plastic film and watering enough water. Its survival rate can be close to 100%. If there is a lack of seedling hole in summer, it is necessary to replenish the seedling in time.

2. Water and fertilizer management

The demand for nutrition of grape growth is relatively large, and the demand for potassium and calcium is the greatest during the whole growth period, followed by nitrogen and phosphorus. When applying fertilizer, we should apply more organic fertilizer and apply enough base fertilizer after the fruit is ripe to promote the growth of the next year. Then, during the fruit expansion period, mature farm manure should also be applied once, mainly in furrow. Water is also very important for the growth of ice grapes. When the water content of the orchard is less than 60%, it should be watered in time. The main watering method is drip irrigation. Water should not be too much, and when too much, we should pay attention to do a good job of drainage to prevent waterlogging.

3. Wiping buds and fixing shoots

When the new tip of the ice grape grows to about 6-9 cm, the buds about 45 cm from the ground should be erased in time. Then, when two new shoots appear on the bracket, keep the new shoots with many inflorescences, stout and well-positioned, and then erase the extra ones. And the buds that are too dense can not be retained, keeping the density of buds on each vine at about 10 centimeters. The time and quantity of sprouting should be controlled according to the tree potential to avoid consuming too much nutrition. Then when the new shoot grows to about 16-18 cm, observe the growth of the new shoot inflorescence. Keep about 9 per square meter and do a good job of fixing the tip.

4. Flower and fruit management

In the period of flower bud and first flower of ice grape, it is easy to spray Sule boron once, which can promote the growth of pollen and improve the fertilization rate of pollen. If the phenomenon of water shortage is encountered during the flowering period, it is necessary to spray and water in time to increase the humidity in the field, reduce the temperature and prevent the bad climate from affecting the growth of ice grapes. The amount of fruit of ice grape has a certain relationship with the tree age, and in order to ensure the protection of yield, it is necessary to increase the leaf area of ice grape. We should estimate the amount of fruit according to the nutrition level and age of ice grape, and then do a good job of keeping fruit.

The above is a brief introduction to the cultivation technology of ice grape. the planting method of ice grape is different from that of ordinary grape. Therefore, we must do a good job in the study of planting techniques before planting. That's all for today's introduction. This article is for reference only. I hope it can help you all.
