摘  要:
本文对宽叶雀稗与不同繁殖方法、地表类型、坡向的生长关系进行研究,结果表明:不同繁殖方法、地表类型、坡向因素对宽叶雀稗叶长、叶宽、盖度和鲜草重均有不同程度的影响。A1B2C2组合(即穴播、水平梯面、半阳坡)对宽叶雀稗的生长最为有利,其盖度为90.2%(比平均值58.1%多30.1个百分点)、鲜草重达8.61 t/hm2(比平均值5.22t/hm2大64.9%)。宽叶雀稗不宜采用撒播草籽繁殖,其盖度和鲜草重均极低。

摘  要:
It was conducted the study on the different breeding methods,types of surface,and growth relationships among the slope directions of the Paspalum wettsteinii. The results show that the different breeding methods,types of surface and slope directions factors have the different degrees of impact on the leaf length,leaf width,coverage and weight of grass of Paspalum wettsteinii. Of which,A1B2C2portfolio( i. e. dibbling,horizontal tread,half sunny slope)is most favorable for the Paspalum wettsteinii growth,with the coverage of 90. 2%( 30. 1% higher than the average value of 58. 1%),and the fresh grass weighed 8. 61 t / hm2( 64. 9% higher than the average value of 5. 22 t/hm2).Broadcasting sowing method is not suitable for the breeding of Paspalum wettsteinii due to the extreme low coverage and fresh grass weight.
