For the first time, 3-4 weeks after flowering, when the fruit size is similar to that of soybean, the grapes are completely drained and the overloaded fruits are drained. The earlier the fruit is set, the more stable it is, which not only saves labor, but also fully increases the fruit size. You can't thin the fruit too early. It is not easy to distinguish between large and small fruits and whether it is really fertilized, which is easy to reduce production. Too late fruit thinning and too many peaches waste nutrition.

Precautions for grapes, fruits and vegetables:
1, it is best to leave a small drainage belt above the ear and cover it outside the bag, which can drain the rain and dew outside the bag and reduce the occurrence of diseases in the bag.
2. Collison weighs about 6g, and the string is about1.5-1.8kg, that is, 120- 150 pieces. A single ruby weighs about 5 grams, and the string weighs about 2 kilograms, which means that 200 pieces are enough.
3. According to the conventional ear shape, pruning can be roughly summarized into several routines. Pairwise symmetry, each layer has two auxiliary spikes, and four layers with one spike will have about1.2kg. Three or three layers, each layer has three auxiliary spikes, and three layers plus one spike is one and a half pounds.
