Water the fertilization lock shed and pour water once to facilitate germination. Combine watering per plant with perforating fertilizer Shennong Bao No. 1 liquid fertilizer 75 to 100 ml or ternary compound fertilizer 0.5 to 1 kg.

Flowering stage mixed spraying 50 mg/liter gibberellin, 0.2% borax solution once to improve fruit setting rate. 3~4 weeks after flowering, fruit thinning is usually carried out. Generally, fruiting branches (30 to 60 cm) leave fruit 3 to 5, middle fruiting branches (15 to 35 cm) leave fruit 2 to 3, and short fruiting branches (5 to 15 cm) to stay. Fruit 1 to 2.

Prevention of nectarine diseases, spraying with Baumide Lithosulfide mixture 1 to 2 times after the shed, spraying Dasheng M-45 (80% Mancozeb WP) or 70% Thiophanate-methyl after spraying Wettable powder 600 to 800 times, once every 10 to 15 days, continuous control 3 to 5 times. When maggots and ticks are harmful, they are sprayed with 10% imidacloprid WP 2000 to 2500 times and 15% DF 1500 times.
