T/WSCL 0001-2021 Environmental Conditions of the Production Area of Wushan Crisp Plums
T/WSCL 0001-2021
Basic Information
Scope
Main technical content: 4. Temperature: Wushan crispy plums have a wide adaptability to temperature. The annual average temperature during the growth season should be between 13°C and 18°C, and the cold requirement during the dormant period should be ≤7.2°C for 700–1000 hours. The critical temperatures for low-temperature frost damage are: flower bud stage –1.1°C–5°C, flowering stage 0.6°C–2.5°C, and young fruit stage 0.6°C–1.0°C. 5. Humidity: Wushan crispy plums have strong drought resistance but poor waterlogging tolerance. For normal growth, the soil field moisture content should be around 60%. 5.2 Moderate drought: flower bud differentiation period and dormant period. 5.3 Harmful moisture: continuous rain during flowering and fruit ripening. 6. Light: Wushan crispy plums are highly light-loving, and the annual sunshine duration should be no less than 1,571 hours. 7. Soil: 7.1 The soil should be deep, fertile, and have good water and fertilizer retention, as well as good aeration. 7.2 The soil pH value should be between 6.5 and 7.5.
