The grapes are first germinated and then placed on the shelves

It was time for the grapes to be unearthed. Grape growers asked when the grapes would be unearthed. How to manage after unearthing? In recent days, the author visited a special grape-growing household with years of planting experience. Now he describes his practice as follows.

The timely unearthing of grapes is extremely important. For many years, some fruit growers have often “earned” their time according to their experience. This is unscientific because the temperature at the same time every year is different. The scientific approach is: when the day and night temperatures reach an average of 10°C, they can be unearthed. It has been observed that the temperature at which apricot blooms is the temperature at which grape roots are active. "Apricot blossom, grapes unearthed" is this truth. This period is basically in every year from March 20 to early April.

In addition, after the grapes are removed from the cold soil, do not put them on the shelves and let the shoots lie on the ground to germinate. When the germination bud grows to the size of the peanut, it is attached to the shelf. This can generally increase production by 20% to 40%. Because the top of the grape has a strong advantage, if germination is done in an upright state, the upper buds are too prosperous, the middle buds are moderately weak, and the lower buds are inhibited or even unable to sprout, resulting in severe reductions in yield. If the shoots are allowed to germinate in a roughly horizontal and slightly apical state, the buds above and below the shoots will germinate uniformly, and the result will be normal. However, it is not allowed to put on the shelves when the buds are very large. As a result, the shelves will hit many buds and cause losses.
