摘　　要：应用１５Ｎ稀释法研究南京地区土壤条件下粪产碱菌耐铵型工程菌株—水稻作物联合固氮能力。结果表明，紫香糯稻用粪产碱菌耐铵型工程菌株接种后，固氮量为３９．７ｋｇ／ｈｍ２，固氮率为１６．２％。水稻植株利用固定的空气氮素后。The ability of nitrogen fixation of ammonium resistant strain of Alcaligenes faecalis associated with rice plant at the soil of Nanjing had been studied by using 15 N dilution method.The results showed that the fixed nitrogen amount of glutinous rice inoculated with engineering bacteria to Alcaligenes faecalis was 39 7 kg/hm 2,and its rate of fixed nitrogen was 16 2%.The applied amount of ammonium sulphate on rice field may be decreased after rice plant had used the fixed nitrogen from air.
