The Latest Ice Grape Planting Techniques and Methods Tutorial
Ice grape is a new type of grape variety; after the fruit ripens, it can remain on the vine for a long time even without being harvested. Its harvest period can be delayed by about one month. Nowadays, ice grapes can not only be eaten fresh, but are also the main raw material for ice wine; the wine made from them has a mellow taste and good quality, and is loved by many people. So how should ice grapes be planted? Below, the editor brings you the planting techniques for ice grapes. Let's take a look!
1. Seedling selection and orchard establishment
Ice grape seedlings should have more than 7 lateral roots, with a length of no less than 18 cm, and should have many fibrous roots. Then, before planting, do a good job of land preparation, control the planting density well, and dig the planting trenches properly. The depth and width of the planting trenches should be controlled at about 50*50 cm. Then apply sufficient base fertilizer, mainly farmyard manure. If the soil's moisture-retention capacity is not strong, then during planting, water thoroughly and firm the soil by treading on it. Then form ridges of about 12 cm, cover with plastic film, and water thoroughly. Its survival rate can approach 100 percent. If missing-plant gaps are found in summer, replant seedlings in time.
2. Water and fertilizer management
Grape growth has a relatively large demand for nutrients. Throughout the entire growth period, the demand for potassium and calcium is the greatest, followed by nitrogen and phosphorus. When fertilizing, apply more organic fertilizer. After the fruit ripens, apply a sufficient basal fertilizer to promote growth the following year. Then, during the fruit enlargement period, also apply a topdressing of decomposed farmyard manure, mainly by trench application. Water is also very important for the growth of ice grapes. When the water content of the orchard is below 60 percent, water in time, mainly by small-drip irrigation. Water should not be excessive either; when there is too much, pay attention to doing a good job of drainage to prevent waterlogging damage.
3. Bud removal and shoot thinning
When the new shoots of ice grapes grow to about 6-9 cm, promptly remove the buds about 45 cm from the ground. Then, when two new shoots appear on the trellis, keep the new shoot with more inflorescences, that is thick and strong, and in a good growing position, and remove the excess. Also, overly dense buds must not be kept; maintain the density of buds on each vine at about 10 cm. Control the timing and number of bud removals according to tree vigor to avoid consuming too many nutrients. Then, when the new shoots grow to about 16-18 cm, observe the growth of the inflorescences on the new shoots. Keep about 9 per sq m and do a good job of shoot thinning.
4. Flower and fruit management
During the periods of flower buds and early flowering of ice grapes, pay attention to spraying once with quick-acting boron and similar substances to promote pollen growth and improve the pollen fertilization rate. If water deficiency occurs during the flowering period, then spray water in time to increase field humidity, lower the temperature, and prevent adverse climate from affecting the growth of ice grapes. The fruit yield of ice grapes is related to tree age and tree vigor to a certain extent, and to ensure yield protection, it is necessary to increase the leaf area of ice grapes. We should estimate the fruit yield according to the nutritional level and tree age of the ice grape vines, and then do a good job of fruit retention.
The above is a brief introduction to ice grape planting techniques. The planting methods for ice grapes are somewhat different from those for ordinary grapes. Therefore, before planting, be sure to do a good job of learning the planting techniques! That's all for today's introduction. This article is for reference only, and I hope it can help everyone!
