稀土处理对设施黄瓜幼苗生长的影响

Effect of Rare Earths Treatment on Cucumber Seedling Growth of Greenhouse

试验以黄瓜津春4号为材料,研究不同浓度稀土喷施处理对设施黄瓜幼苗生长的影响,探讨促进黄瓜幼苗生产的最佳稀土处理浓度。结果表明,喷施稀土后可促进设施黄瓜幼苗生长,有利于培育壮苗。与对照相比,1 200倍稀释液的稀土处理效果较好,处理14 d后,株高、茎粗、根系数量、光合速率、根冠比、壮苗指数分别比对照提高了19.17%、5.31%、44.00%、66.83%、19.05%、13.46%,效果较为显著。

The cucumber Jinchun No.4 was selected to study the affection of seedlings of cucumber growth by different concentrations of rare earths treatment in greenhouse.The results showed that suitable rare earths treatment accelerated the growth of seedling and promoted the breeding of healthy seedling.The treatment of 1200 times had an obvious effect on the height,stem diameter,root number,photosynthetic rate,shoot ratio and healthy index of cucumber,which increased 19.17%,5.31%,44.00%,66.83%,19.05%,13.46%,compared with the contrast.
