What precautions should be taken when thinning grape flower clusters?
1. The purpose of thinning grape flower clusters: it further adjusts the yield on the basis of bud removal and shoot thinning, achieves a reasonable load on the vine, saves nutrients, and improves fruit set rate and fruit quality, so as to achieve the goal of producing high-quality, high-efficiency grapes. 2. The timing of grape flower thinning: when the number and size of the flower clusters on the new shoots can be clearly distinguished, ...
1. The purpose of thinning grape flower clusters: it further adjusts the yield on the basis of bud removal and shoot thinning, achieves a reasonable load on the vine, saves nutrients, and improves fruit set rate and fruit quality, so as to achieve the goal of producing high-quality, high-efficiency grapes.
2. The timing of grape flower thinning: when the number and size of the flower clusters on the new shoots can be clearly distinguished, carry it out as early as possible to save nutrients and promote growth. Avoid causing unnecessary nutrient waste.
3. The method of thinning grape flower clusters: for a few strong shoots, generally keep 1-2 flower clusters; for fruiting shoots with moderate vigor, keep one flower cluster; for weak shoots, keep none. This achieves a reasonable leaf-to-fruit ratio and ensures the yield and quality of the berries.
