After planting, it is necessary to strengthen the management of fertilizer and water, timely prevent and control pests and diseases, ensure its normal growth and development, prevent drought, less fertilizer, seedlings, promote vegetative growth, and inhibit reproductive growth. Under the premise of strengthening management, gushing 20 to 50 mg/liter of gibberellic acid every 7 to 10 days during the prosperous period of growth, and spraying 2 to 3 times, can promote vegetative growth and slow down convulsions.
