1.控制棚内温度。草莓花期,如遇0℃以下低温会丧失授粉受精能力,30℃以上高温也会使花粉发育不良。因此,在冬季及早春,大棚内要套中棚再加小棚,并在地面覆盖地膜,共计四层,力争棚内白天温度达到25～28℃,夜间达到5℃以上,最低不低于0℃。在气温较高时,采取通风等办法,使最高温度控制在32℃以内。
1. Control the shed temperature. Strawberry flowering, in case of low temperature below 0 ℃ will lose pollination fertility, high temperature above 30 ℃ will pollen dysplasia. Therefore, in winter and early spring, the greenhouse should be set in the shed plus shed, and the ground cover plastic film, a total of four layers, and strive to shed daytime temperature reached 25 ~ 28 ℃, at night to reach more than 5 ℃, the minimum is not less than 0 ℃. When the temperature is high, take the ventilation method, the maximum temperature control within 32 ℃.
