松针/椰糠基质中微生物菌剂和微量元素对辣椒苗期生长的影响

Effects of microbial product and trace elements in pine needle/coconut coir substrate on seedling growth of Capsicum annuum L.

针对松针/椰糠基质分解不充分自身缺乏养分和微量元素,不足以满足辣椒苗期生长需求的问题,通过育苗盘试验,研究添加不同微生物菌剂和微量元素对辣椒苗期幼苗生理特性、叶绿素含量及叶绿素荧光特性的影响。结果表明,在绿陇0.16 g/株(A3)和克黄威0.08 g/株(B2)处理下辣椒幼苗生长效果最好,各生理指标与对照相比都显著提高,其中壮苗指数和根冠比分别增加49.66%、11.37%和44.30%、10.87%;叶绿素含量和PIabs较对照分别提高19.17%、34.76%和29.41%、32.37%。松针/椰糠基质中添加绿陇和克黄威可促进基质分解,有利于辣椒萌发,补充苗期营养,对PSII系统有较大影响,可促进幼苗光合作用等生理生长进程。

In terms of Pine needle/coconut matrix is not fully decomposed and lacks nutrients and trace elements, which is insufficient to meet the growth requirements of seedlings of Capsicum annuum L.. The effects of different microbial agents and trace elements on the physiological characteristics, chlorophyll content and chlorophyll fluorescence characteristics of Capsicum annuum L. seedlings were studied by seedling tray test. The results showed that under the treatment of Lvlong 0.16 g/plant(A3) and Kehuangwei 0.08 g/plant(B2), the growth of Capsicum annuum L. seedlings was the best, and the physiological indexes were significantly improved compared with the control. The seedling index and root-shoot ratio increased by 49.66%,11.37% and 44.30%, 10.87%, respectively. The chlorophyll content and PIabs increased by 19.17%, 34.76% and 29.41%,32.37%, respectively. The addition of Lvlong and Kehuangwei to the pine needle/coconut matrix could promote the decomposition of the matrix, which was beneficial to the germination of Capsicum annuum L. and supplement nutrition at the seedling stage. It had a great influence on the PSII system and promoted the physiological growth process such as photosynthesis of the seedlings.
