摘要
通过对有无管理因素作用下 ,不同年代建植草坪杂草种群入侵与比率的研究 ,按样方法 (0 2 5m2 )进行 5次重复 ,对不同草坪及杂草 ,在不同季节和刈次下 ,进行株高、盖度、分蘖 (枝 )、总株丛数、出现率、样方产量等项测定。获得系统全面的定量分析资料 。
The ratio of the weed population invaded into the Lawns Which were planted in different time and managed in different ways was studied. The individual plant height,covering area,tillering,total patches of grass,frequency,and yield of sample area were measured.The systematic data can provide scientific basis for effective chemical weeding.
