冬春李节常出现连阴天气,棚室内的光照强度极低,空气相对湿度在95%以上,室内温度在15℃以下。连续几天的阴天,环境限制了草莓叶片的光合作用,减少光合产量,会使草莓坐果率低、幼果生长停止、产生畸形果,果实产量下降,果实成熟期推迟。因此,棚室草莓在连阴天时应抓好以下管理措施:
The winter and spring often appear Li Liangyun weather, shed light intensity is very low, the air relative humidity above 95%, the indoor temperature below 15 ℃. On cloudy days, the environment limited the photosynthesis of strawberry leaves and reduced the photosynthetic output, which led to the low fruit set rate of strawberry, the cessation of young fruit growth, the abnormal fruit formation, the decrease of fruit yield and the delay of fruit maturation. Therefore, the studio strawberries should catch the following management measures in the cloudy days:
