摘要
小麦接种VA菌根和小麦根际联合国氮菌处理有显著的增产效果,其产量分别比对照提高9.662％和6.01％,接种VA菌根加固氮菌的处理,产量此对照提高16.83％,接种VA菌根的处理分蘖成穗率高达61％,有效穗比对照提高了8.66％;接种固氮菌的处理,穗粒数比对照提高9.3％,各处理的干物质积累都优于对照。
To inoculate VA mycorhiza and wheat rhizosphere azotobacter has significant effect which can increase the yield up to 9.62％、6.01％ in comparison with check respectively. The treatment of inoculating VA mycorhiza+azotobacter can raise yield 16.83％; but only VA mycorhiza the rate of productive fillers 61％ the number of fillers increase 8.66％; only azotobacter, the number of grains per ear is more 9.3％ than check. As to accumulation, each treatment is superior to check.
