Under the premise that the mother branch and the result branch are strong and full, and the results are suitable, the light conditions and the fertilizer and water conditions are good, a series of technical measures are taken to promote the early maturity of the grapes, and good economic benefits can be obtained.
What are the ways to promote early maturity?
1, increase the cultivating can ripen
When the grapes grow most vigorously, it is just in the rainy season. At this time, people work in the garden more frequently, and there will be knots on the ground, which will affect the formation and maturity of the grapes. At this time, as long as the number of cultivating is increased, it will be promoted. The role of grape precocity. Adding biological bacterial fertilizer or soil activator during cultivating is more effective and helps to loosen the activated soil.
2, plastic film cover
After the mulch film is covered, the ground temperature is improved and the light is improved, so that the sugar content of the grape is increased, and the fruit pieces are colored in advance. In particular, the silver reflective film greatly increases the reflection of light, and the effect is particularly outstanding.
3, ear bagging
In the lower temperature area, when the inflorescence is extended, the flower-like film bag is used to cover the inflorescence, and when the young fruit falls off, the bottom of the bag is torn open, and the "bag" is changed into a "tube". This method can make the grape ripen early. 15 days.
4, ring peeling and ripening
In the result, 3 cm under the fruiting node and the base of the mother branch are stripped at the beginning of the ripening of the berries, which can be matured for about 5-7 days. Matters needing attention: (1) The branches with weak growth are strictly prohibited from ringing. (2) The number of rings on the same tree should not exceed 40%. (3) The width of the stripping should not exceed 3mm, the knife edge is straight, and it is wrapped with plastic film after peeling.
5, remove the old leaves can ripen
By removing the old leaves near the grape fruit, the grape fruit can absorb more sunlight, and the fruit pulps faster, which also plays a ripening role.
6, spraying potassium fertilizer ripening
After the grape fruit is pulped, the potassium fertilizer can be sprayed on the leaf surface. This can make the coloring of the fruit even, and the maturity time is too early. When spraying the potassium fertilizer, the frequency is not too much, and it can be sprayed once a week.
7, ripening with a regulator
After the fruit of the grape is softened, plant-forming regulators can be used, which can also play a ripening role. Ethephon and naphthalene acetic acid are commonly used plant growth regulators. After purchase, you can use the above instructions. After spraying, the grapes will mature quickly. If you want to increase the sweetness of the fruit at the same time, the sugar-staining colorant on the market can also be used, but you must look for regular manufacturers to avoid unnecessary losses. Taiwan's Longtai Agriculture's "color skin" is a good coloring sweetener.
