摘要
光照是蔬菜生长的必需条件,北方冬季光照时间短,不利于喜光温室蔬菜的种植。温室LED补光设备是根据植物的光照需求特性而设计,试验证明,应用LED补光技术的西兰花比不补光的对照区增产14.3%,而且西兰花的花密色深,采收期提前。
Light is essential for vegetable growth. Light irradiation time is short in northern winter,and it is not conducive to the light greenhouse vegetable cultivation. Test and application of greenhouse plant LED lighting equipment was designed according to light of plant to demand characteristic. Experiment results showed that yield of broccoli that using LED lighting technology increased 14. 3%,flowers were dense and color was dark,and harvest time was in advance than not using LED lighting technology.
