不同光照处理下西葫芦的生长分析

Growth Analysis of Summer Squash under Different Light Treatments

为探索设施栽培下西葫芦的最佳补光光源,在NFT植物工厂分别用红蓝双色光、白色单色光、全光谱灯光、红蓝白三色光对西葫芦进行光照处理,比较不同处理下的西葫芦生长情况。结果表明,白光和全光谱处理可以促进西葫芦光合产物向茎叶部分分配;红蓝光源处理下西葫芦根的长度长于同时期其他处理的根长,但在40 d左右达到峰值后停止生长,而其他处理根长会持续伸长;白光处理下的西葫芦叶片要小于同时期其他处理下的叶片大小。综合比较,全光谱是作为西葫芦设施栽培最佳的人工补光光源。

In order to explore the best supplemental light source for zucchini under facility cultivation,in the NFT plant factory,red and blue light,white monochromatic light,full spectrum light,red,blue and white light were used to illuminate the zucchini,and the zucchini under different treatments were compared growth situation.The results showed that white light and full spectrum treatment could promote the distribution of zucchini photosynthetic products to the stems and leaves.The root length of summer squash under the red and blue light source treatment was longer than the root length of other treatments in the same period,but it stoped growing after reaching a peak in about 40 days,and other root length of the treatment would continue to grow.The leaf size of the zucchini under the white light treatment was smaller than that under the other treatments at the same time.Comprehensive comparison,full spectrum was the best artificial light source for the cultivation of zucchini in facility.
