通过盆栽模拟试验研究比较以Glomus mosseae(GM)和Glomus etunicatum(GE)为接种剂,设置不同根系分隔方式(不分隔,隔尼龙网,隔塑料膜)对间作玉米植株生长及磷素吸收累积的影响。结果表明,两种菌根真菌GM和GE对玉米根系的侵染效果相近,GM为玉米优势丛枝菌根真菌(AMF),接种GM使玉米根长、地上部和根系生物量、地上部和根系磷含量、磷吸收量均显著提高;接种GE显著降低了玉米根冠比、株高和根系磷吸收效率。间作体系不同根系分隔方式对玉米的影响也不同,根系隔尼龙网处理显著降低了玉米根长和根系生物量,显著提高了根系的磷含量;根系隔塑料膜处理对玉米的地上部和根系磷含量、磷吸收量以及根系磷吸收效率均起显著降低作用。所有复合处理中,以GM不分隔处理组合对间作玉米的生长及磷素累积的促进作用最好。
Pot experiments were conducted to compare the accumulation and accumulation of plant growth and phosphorus uptake in intercropping corn with Glomus mosseae (GM) and Glomus etunicatum (GE) as inoculants by different root segregation patterns influences. The results showed that two kinds of mycorrhizal fungi, GM and GE, had similar effect on maize root inoculation. GM was AMF, and the effect of GM on root length, aboveground and root biomass, Phosphorus content and phosphorus uptake of roots were significantly increased. GE inoculation significantly reduced root / shoot ratio, plant height and root phosphorus uptake efficiency. The effects of different root partitioning methods on maize were also different. The root nylon net treatment significantly reduced the root length and root biomass of maize, and significantly increased the content of phosphorus in the root system. The root plastic film treatment on the shoot and root of maize Content, phosphorus uptake and root phosphorus uptake efficiency all play a significant role. In all compound treatments, the combination of GM non-separated treatment had the best effect on the growth and phosphorus accumulation of intercropping corn.
