Scope

Main technical content: 10.1 Winter cultivation in the Guanzhong region: - Sowing period: September 10 to October 31 for winter greenhouse cultivation; - Sowing period for early spring greenhouse cultivation: November 10 to December 20; - Sowing period for early spring greenhouse cultivation: December 20 to January 31. 10.2 For early spring cultivation: - Leaving 5 fruiting branches per 667 m2 (2600–3000 branches/667 m2); - Topping off at 2–3 fruiting branches per 667 m2 (3000–3500 branches/667 m2); - Winter cultivation: 2000–2200 branches/667 m2. 10.3 For early spring cultivation: - During the flower bud differentiation period (2–6 leaves), maintain strict temperature control with nighttime temperatures not falling below 12°C. 10.4 For winter cultivation: - During the low-temperature and low-light period from December to January, maximize light exposure and ensure adequate insulation. 10.5 Deep tillage to a depth of 30 cm and application of sufficient base fertilizer: - 10,000 kg/667 m2 of high-quality organic fertilizer; - 100 kg/667 m2 of diammonium phosphate; - Appropriate amounts of potassium sulfate and urea (30 kg/667 m2); - Mixed trace element fertilizer (30 kg/667 m2). - Alternatively, apply 2000 kg/667 m2 of well-rotted dried chicken manure or 1500–2000 kg/667 m2 of high-quality organic fertilizer. - Apply ⅓ of the fertilizer as a top dressing and ⅔ as a furrow application. 10.6 Use hormones to promote fruit set at low concentrations. Reduce the concentration by more than 20% according to the instructions. 10.7 Prevent fruit cracking during the late harvest period by avoiding excessive irrigation and controlling ventilation. 10.8 When soil temperatures exceed 28°C, the resistance to root-knot nematodes decreases. Use avermectin and other preventive measures as needed. 10.9 This variety is not resistant to yellowing mosaic virus. Use with caution in areas and seasons where this disease is prevalent.
