  通常情况下照射范围大的补光灯距离蔬菜较远激光植物生长灯网上赚钱吧,高度保持在距生长点1.5-2米左右的距离,照射范围较小的补光灯一般安装在蔬菜生长点上方0.5-1.5米的距离。如果是单纯的补光灯,可距蔬菜生长点稍近,而如果是既有补光效果又有加温效果的灯具,则需要与蔬菜生长点保持一定的距离,以免过近对蔬菜造成伤害。如果距离过远则会降低补光效果。


番茄的光饱和点为7万勒克斯,光补偿点2000勒克斯。每天日照时数12到14小时激光植物补光灯,光照强度达4万至5万勒克斯为番茄理想的光照条件。如果光照较弱,低于1.3勒克斯,则花芽分化大为延迟,即使增施氮肥,也不能克服这种弱光的影响,容易落花。番茄对光照长度要求不严激光植物生长灯多少钱,增加光合作用时间,对花芽的形成及植株的生长都是有利的。

  浇水:保温后土壤水分蒸发加快,尽管有地膜及棚膜覆盖,土壤扔容易缺水。草莓是喜水怕涝植物,因此,隔一段时间就应浇水,使土壤水分充足,浇水原则是“湿而不涝,干而不旱”。判断是否该浇水应观察早晨叶面水分,如果叶面边缘有水滴,即出现吐水现象,可以认为水分充足,相反,则表示缺水需及时浇水。    追肥:除了施足底肥外,根据植株生长情况,可在覆盖地膜前、现蕾期、果实膨大期或采收盛期进行追肥。追肥间隔时间,生长前期间隔20天,生长后期为1个月。每次每亩追施5千克优质水溶肥,追肥后及时浇水。此外,在草莓初花期和盛花期喷2-3次等硼肥,此后喷施2-3次钙肥,能明显提高坐果率和大果率。根外追肥可间隔7-10天喷一次0.3%的磷酸二氢钾。
