草坪在其生长和养护使用中,经常出现长势减弱,草坪衰退,未老先衰的退化现象,降低了草坪的效益。笔者经过五年多的调查和研究认为:形成草坪退化的原因主要有三个方面:一是草坪草的品种选用不当。因不同的品种受其遗传特性制约,自身抗逆性有明显差异,抗逆性强的不易退化,反之.则退化早而快。二是环境失调。当气候、土壤等不利于草
Lawn growth and conservation in its use, often weakened growth, lawn recession, the degradation of premature senility, reducing the efficiency of the lawn. After more than five years of investigation and research, the author believes that there are mainly three reasons for the formation of lawn degradation: First, improper selection of turfgrass varieties. Due to the different varieties of their genetic characteristics of constraints, their own significant differences in resistance to stress, strong resistance to degradation is not strong, whereas the degradation of early and fast degeneration. Second, the environment is imbalanced. When the climate, soil, etc. is not conducive to grass
