在球场养护中,PH值的管理往往为管理者所忽视。不像施肥交播等养护措施能获得立竿见影的效果,PH值对于草坪的影响比较缓慢。其实,管理好土壤PH值是最重要的维护工作之一,如果你长时间忽略PH值的管理,一旦它偏离过多,会对草坪正常生长产生严重的影响,导致草坪对肥料的吸收下降、枯草层加厚以及病虫害加重。PH值是一个表述土壤酸碱度大小的指标,其范围从0-14,其中7.0为中性,要特别理解的是PH值是一个10的指数,例如PH值5.0的土壤其酸性要比6.0的土壤酸性强10倍,因此,看似近似PH值的土壤,
In the course of conservation, PH management is often overlooked by managers. Unlike fertilizer conservation and other conservation measures can get immediate results, PH value of the lawn more slowly. In fact, the management of the soil PH value is one of the most important maintenance work, if you neglect the management of PH for a long time, once it deviates too much, it will have a serious impact on the normal growth of the lawn, resulting in lawn fertilizer decreased absorption, Thickening of hay plants and aggravation of pests and diseases. The pH value is an indicator of soil pH, ranging from 0-14, of which 7.0 is neutral. It is specifically understood that the pH is an index of 10, for example, a soil with a pH of 5.0 is more acidic than a soil of 6.0 Acid 10 times stronger, therefore, seemingly similar to the pH of the soil,
