1晴天日光温室生产管理措施1.1水肥管理果菜类蔬菜根系生长的适宜温度为25~28℃,温度低于15℃,不能开花,且授粉受精不良,温度降至10℃时,植株停止生长,长时间5℃以下低温易引起低温危害。日光温室越冬果菜在前期浇透水的基础上不旱不浇,浇水时要看天、看秧、测地温,并注意收听天气预报,做到浇水后有3~5d晴朗天气,并及时放风排湿。追肥要根据作物长相和生长期长短,按照平衡施肥要求适时追肥,同时应有针对性喷施微量元素肥料。
1 sunny day solar greenhouse production management measures 1.1 Water and Fertilizer Management Fruit and vegetable vegetables root growth of the appropriate temperature is 25 ~ 28 ℃, the temperature is below 15 ℃, can not flowering, pollination and fertilization poor, the temperature dropped to 10 ℃, the plant stops growing, long Low temperature below 5 ℃ can easily lead to low temperature damage. Sunshine greenhouse winter fruit and vegetable in the pre-irrigation water is not on the basis of drought is not poured, watering depends on days, see seedlings, ground temperature, and pay attention to listen to the weather forecast, so after the watering 3 ~ 5d sunny weather and timely ventilation Moisture. Top dressing should be based on the length of the crop and the growth period, in accordance with the requirements of balanced fertilization timely top dressing, should also be targeted to spray trace element fertilizer.
