交联聚丙烯酰胺和AM真菌对玉米苗生长、养分吸收和生理指标的影响
摘要
在玉米育苗基质中加入交联聚丙烯酰胺(crosslinked polyacrylate amine
CPA)和接种AM真菌
研究它们对玉米苗生长、养分吸收及有关生理指标的影响。结果表明
在-CPA的基质中
接种AM真菌的玉米苗生物量高于不接种
并且增加磷含量与吸收量
提高硝酸还原酶活性;在+CPA的基质中
CPA提高了玉米苗P含量以及吸收量
适量的CPA浓度还能够提高玉米苗的生物量
CPA显著降低AM真菌的感染率
接种AM真菌后的玉米苗生物量与不接种的相似甚至更低
玉米苗养分吸收、硝酸还原酶、叶绿素和根系活力因菌株和CPA含量不同而异。由于降低AM真菌的感染率
不能进一步改善菌根玉米苗生长
菌根效应被CPA的促生作用掩盖甚至超过
故在实际育苗工作中
建议采用接种AM真菌或在基质中适量加入CPA一种方式即可。
Abstract
The corns were cultured with cross linked polyacrylate amine(CPA) added and arbuscular fungi(AM fungi) inoculated into culture medium
respectively
to study their influence on growth
nutrient uptake and some physiological indices of corn seedlings.The results showed in the medium without CPA the biomass
the content and absorption of phosphorus
the activities of nitrate were improved by fungal inoculation.In the medium with CPA the content and absorption of phosphorus
