| 摘 要： | 从沈阳农业大学试验基地中分离出两株具有解钾能力的细菌C1和Y3,解钾量分别比对照提高44.8%和26.2%,对其生理生化特性分析,确定为芽孢杆菌属,其中C1对4株植物致病真菌有较强的抑制作用。在玉米盆栽试验中,C1和Y3对苗期玉米都有一定的促长作用,体现在植株高度和地上部干重,较对照分别提高了14.5%、31.9%和11.4%、26.7%,均达到显著水平。

| Abstract: | Two strains of bacterium named C1 and Y4 were isolated from Shenyang Agricultural University experimental fields,which identified as Bacillus by physiological and biochemical tests.C1 and Y4 had the ability of releasing K+ from soil,and were increased by 44.8% and 26.2% compared with control.C1 had a strong antagonism of plant pathogenic fungi.In the pot experiment of corn,C1 and Y4 played a certain role in growth-promoting of seeding stage of corn.Plant height increased respectively by 14.5% and 11.4% and ... |
