Grape sapling management technology

First, from the time the grapes germinate to the end of August, apply topdressing once a month. Each time, each plant uses 5 kg of farmyard manure and 50 grams of nitrogen fertilizer to apply thin fertilizer. Second, the new planting grape vines stand small Lead the new shoots, when the new shoot grows to about 20 centimeters, you can choose to leave one stout new shoot and erase the other tender shoots. To promote the development of secondary shoots and plastic surgery, the shoots will be picked up when the new shoots grow to the shelf height. During the winter cut, the secondary shoots were used as the backbone branches to see early formation. Third, maintaining loose orchard soil can increase root growth and reduce the occurrence of pests and diseases.
