摘要
试验在大豆初花期用２０ｍｇ·Ｌ－１柠檬酸钛喷施植株，在盛花期和结荚期对大豆株高、干物重及根瘤固氮酶活性和固氮强度进行测定，与对照相比均有不同程度提高；收获后大豆籽粒产量与对照差异达显著水平。经化学分析，大豆籽粒中蛋白质含量也比对照显著提高。
Cirtate titanium was sprayed at the early flowering stage of soybean The dry matter weight, plant height, the activity of symbiotic nitrogen fixation enzyme and the intensity of N fixation all increased and the yield was positively significant difference from that of CK
