| 摘 要： | 采用4种土壤改良剂对黄河沿岸兰州段盐碱土壤进行改良,观察了改良土壤上多年生黑麦草的生长情况。结果表明,YNEC、康乐、圃园和绿能4种土壤改良剂各用量处理都能不同程度的促进多年生黑麦草的生长;在相同用量水平下,改良剂康乐可明显增加草层高度和植物量;4种改良剂都能促进多年生黑麦草的分蘖,分蘖数随改良剂施用量的增大呈增加趋势,其中改良剂康乐对分蘖的促进作用最为明显,改良剂圃园的效果相对较差;随改良剂施量的增加,各处理地上植物量增大,以2 kg/m2土壤改良剂地上植物量最大。 |

| Abstract: | Four soil amendments(YNEC,KANGLE,YUANPU and LIUNENG) were used to improve the saline soil along with Yellow River and perennial ryegrass was used to test the effect of soil amendments.The growth characteristics of perennial ryegrass were studied field experiment and the result showed that 4 soil amendments could speed up perennial ryegrass growth.KANGLE could remarkably increase the grass height and phytomass of ryegrass.YNEC and LUENENG showed stronger effect on root length than the other two.All of the soil amendments could improve the tiller development of ryegrass,and with the increasing of application rate,number of tiller could be increased. |
