紫花苜蓿接种根瘤菌施用石灰试验(1987～1989年)

AN EXPERIMENT ON INOCULATION OF RHIZOBIUM TO ALFALFA AND LIMING(1987～1989)

两年试验表明,在红壤丘陵岗地上种植紫花苜蓿,接种根瘤菌结合施用石灰,生长第一年花期结瘤数及青草产量比对照高127.5%及59.3%,越夏率高9.3%;生长第二年花期结瘤数及青草产量分别比对照高34.8%及54.7%,越夏率提高17.2%,增效显著.

The experiment for two years showed that the amounts of nodules at theflower stage and fresh yield of alfalfa treated with inoculation of rhizobiumin the first growth year were higher 127.5%,59.3% respectly than those ofthe control,the oversummering percentage was higher 9.3% than that in thecontrol on red soil hilly land.The amounts of nodules at the flower stage andfresh yield of herbage in the second growth year were higher 34.8%,54.7%respectly than those of the control,the oversummering percentage raised 17.2%;the difference was remarkable.
