摘要
在灭菌肥团土壤中采用接种AM真菌(G+)、不接种AM真菌(G-),以及不灭菌肥团土壤中不接种AM真菌(CK)3种处理,研究肥团接种对玉米(ZeamaysL)菌根化、生长和生理生态的影响。结果表明,肥团菌根化育苗能显著促进幼苗生长,并能在成年植株根尖的皮层中形成大量的菌丝体和泡囊,而G-和CK处理的菌根感染率很低,证明接种显著地促进了玉米根系的菌根化,由此而增强了玉米植株的吸收能力,增加了植株叶绿素含量,促进了成年植株及其雌穗的生长,提高了玉米植株的抗干旱耐高温能力,提高了玉米产量。
Maize seeds were sown in sterilized soil balls with or without AM fungi inoculation (G+ and G-) or in non-sterilized soils balls without inoculation as the control (CK) before transplanting to the field. G+ significantly improved the growth of the seedlings and formed numerous mycelia and vesicles of AM fungi in the cortex of the root tips of mature plants, while the AM infection rate in G- and CK war very low, suggesting that treatment G+ can remarkably stimulate the formation of mycorrhiza on the maize root system, thus enhancing the absorbency, and resistance to drought and high temperature, increasing chlorophyll content in the leaves, stimulating the vegetative and reproductive growth of the plants and improving grain yield.
