新型立体装置对生菜生长和品质的影响

Effects of the New Vertical Device Lettuce Growth and Quality

研究了砂培条件下,几种新型立体装置对意大利生菜形态指标和品质的影响。研究结果表明,新型立体装置T4(有网芯,有溢水孔)能缩短生菜的生育周期,提高产量。在生菜的品质方面,收获前叶片硝酸盐含量明显降低,VC、可溶性糖、蛋白质含量较对照都有明显提高,叶绿素含量、地下部干、鲜质量较对照差异显著。表明新型立体装置T4能改善根际环境,使植株更好地生长,在提高品质和产量方面都有较好的表现。

The effects of new vertical device on the morphlogy and quality was studied in Italian lettuce under the condition of sand cultivation. The results showed that the new device can make the lettuce growth cycle shorted, yield improved. The lettuce cultivated in the new vertical device had better quality than CK in harvest time, such as the content of Vitamin C, soluble sugar and soluble protein, but less than CK in Nitrate of leaves. Its chlorophyll was not prominent than CK. The lettuce cultivated in new vertical device was more prominent at dry root and fresh root than CK. All above showed that the new vertical device can make plant grow better than CK by changing the environment around root.
