4.温度管理春季栽培定植后,气温较低,要搭小拱棚保温;在开花期,温度已逐渐上升,白天温度较高,要开棚通风换气。到了夏季,特别是在中午,气温较高,要覆盖遮阳网遮荫。果实生长和成熟期温度只要达到20～30℃,即可满足其生理生长需要。此阶段应加强通风、透光管理。要特别注意防止 4. Temperature Management Cultivation after planting in spring, the temperature is low, to take a small shed insulation; flowering, the temperature has gradually increased during the day the temperature is higher, to open shed ventilation. In summer, especially at noon, the temperature is higher, to cover shading shade. Fruit growth and maturity as long as the temperature reaches 20 ~ 30 ℃, to meet their physiological growth needs. This phase should be strengthened ventilation, light management. Pay special attention to prevent it
