- 摘要:
- 以设施芹菜为试材，在玻璃温室开展 6 种光质（R、W、B、R1B1、R1B2、R1B3）和4 种哈茨木霉菌浓度（0、105、106、107 CFU·g-1）补光育苗双因素试验，研究不同光照和不同浓度哈茨木霉菌配合使用对育苗的影响，以期为生产健康芹菜苗提供技术支持，并为工厂化育苗提供参考依据。结果表明：R 光显著提升芹菜苗株高、冠幅及地上部鲜质量，且壮苗指数最高；W、B 及红蓝复合光下，株高、冠幅、地上部鲜质量随菌剂浓度升高呈先增后减趋势，106 CFU·g-1时最优；R 光下地上部鲜质量随菌剂浓度增加而升高，红蓝复合光对根系影响较大，H 浓度时根系总长最大，根尖数随菌剂浓度先增后减。主成分分析表明，R 光利于株高、壮苗指数等生长指标提升，106 CFU·g-1菌剂对根尖数、壮苗指数等促进显著。综上，红色单质光显著提高芹菜苗株高、冠幅及壮苗指数，红蓝复合光对根系影响大，106 CFU·g-1哈茨木霉菌促进效果最优。
- Abstract:
- Taking facility celery as the test material,a two-factor supplementary light seedling raising experiment was conducted in a glass greenhouse with six light qualities (R,W,B,R1B1,R1B2,R1B3) and four concentrations of Trichoderma harzianum (0,105,106,107 CFU · g-1) to study the effects of different light conditions and different concentrations of Trichoderma harzianum on seedling raising,in order to provide a reference for the production monitoring of celery seedlings.The results showed that,R light significantly increased the plant height，crown width，and aboveground fresh weight of celery seedlings，with the highest seedling index；under W light，B light，and red-blue composite lights，the plant height，crown width，and aboveground fresh weight first increased and then decreased with the increase of fungal agent concentration，reaching the optimal at 106 CFU·g-1；under R light，the aboveground fresh weight increased with the increase of fungal agent concentration；red-blue composite lights had a greater impact on the root system，with the longest total root length observed at the H concentration，and the number of root tips first increased and then decreased with the increase of fungal agent concentration.Principal component analysis (PCA) indicated that R light was beneficial to the improvement of growth indicators such as plant height and seedling index，while the 106 CFU·g-1 fungal agent significantly promoted the number of root tips，seedling index，and other indicators.In conclusion，monochromatic red light significantly improved the plant height，crown width，and seedling index of celery seedlings；red-blue composite lights had a greater impact on the root system；and the 106 CFU·g-1 Trichoderma harzianum showed the best promotion effect.
