It has been 40 years since dobereiner and ruschel isolated the nitrogen - fixing bacteria from the rhizosphere of sugarcance plants and demonstrated the potential of diazotrophs to associate with graminaceous plants . more recent evidence of significant biological nitrogen fixation in economical important graminous species , particularly sugar cane , rice and forage grasses , has induced tremendous interest in ni fixation by non - legumes 本研究分離、篩選得到一株固氮酶活性高且穩定,生長勢強的聯合固氮菌株,并對其分類地位、形態及生理特征、對環境的適應性及其對植物的促生效果和作用機理作了系統研究,得結果如下。

The results showed the 40 % fomesafen - harness suspension emulsion was safe to soybean field and has good control effect to graminaceous weeds and broadleaf weeds and can not influence the yield of soybean 結果表明: 40 %虎乙懸浮乳劑對大豆田安全對單、雙子葉雜草有較好的防治效果,對大豆產量無影響。
