| 摘 要： | 以常规灌溉（CFI）为对照，利用田间小区试验研究了交替隔沟灌溉（AFI）条件下不同种类丛枝菌根（Glomus mossea，简称BEG167；Glomus diuphauam，简称GD； Glomus versiforme，简称GV）对玉米生长、产量、籽粒氮含量的影响及其差异性。结果表明，AFI显著增加茎干基部直径、次生根数量、根干重和籽粒氮含量，分别增加了6.8%、10.9%、11.5%、11.5%。接种菌根对玉米株高没有影响，但在AFI处理下GV显著增加玉米单株叶面积，且茎干基部直径和次生根数量也分别显著增加了10.3%、15.2%。3种菌根处理均显著增加了根干重，但只有GV对穗干重和籽粒千粒重的增加作用较为明显，尤其是在AFI处理下，穗干重和籽粒千粒重分别显著增加了8.4%和2.5%。3种菌根处理均显著增加了籽粒氮含量，其中BEG增加效果最为明显。AFI条件下不同种类丛枝菌根对玉米生长、产量及籽粒氮含量的影响存在显著的品种差异。

The Yield and Grain Nitrogen Content of Summer Maize Response to Different Arbuscular Mycorrhizal Fungi under different irrigation methods |
| |
| Abstract: | Field experiments were conducted to investigate the effects of different Arbuscular Mycorrhizal Fungi (AMF) (Glomus mossea, BEG167; Glomus diuphauam, GD; Glomus versiforme, GV) on the growth, yield and grain nitrogen content of alternative furrow irrigated summer maize. The results showed that compared with the conventional furrow irrigation (CFI), the base diameter of stem, number of secondary roots, dry weight and grain nitrogen content of per maize root increased significantly by 6.8%, 10.9%, 11.5%, 11.5%, respectively, under alternative furrow irrigation (AFI) treatments. The maize height of AMF inoculation plants were not changed significantly, but the leaf aera per plant of GV inoculation maize increased significantly under AFI, the base diameter of stem and number of secondary roots also increased by 10.3%, 15.2%, respectively. Dry weights of per maize root were all increased by three AMF. The weight of dry ear and per 1000 grain of GV maize significantly increased by 8.4%, 2.5%, respectively under AFI conditions. The three kinds of AMF, especially BEG, increased the grain nitrogen content significantly. The growth, yield and grain nitrogen content response of different AMFs to AFI has varied greatly. |
