杜鹃花性喜凉爽湿润。盆面植草,除美化盆面,减少盆土中营养元素的流失和大雨时盆土沾污叶片外,还可在“三伏”大热天防暑降温,保持盆士湿润,免受根系灼伤。尤其是在气温高、湿度大的霉雨季节,可以在盆土表层的茎部,诱发出较多的气生根,健壮植株,增强抗病力。但杜鹃花盆面植草,在秋冬之际就不甚好。它不但影响植株有效地进行光合作用,而且容易成为蚯蚓等小动物和红蜘蛛等螨类害虫越冬的温床,孕育来年植株的祸患。
Rhododendrons like cool and moist. In addition to beautifying the basin, reducing the loss of nutrient elements in the basin soil and contaminating the leaves in the basin with heavy rain, it is also possible to prevent the root system from being burned by preventing the root system from damaging the summer cooling in the “three-volt” hot days. Especially in the high temperature, humidity, moldy rainy season, you can in the basin surface soil stem, induce more aerial roots, robust plants, enhance disease resistance. But rhododendron pots planted grass, in the autumn and winter is not very good. It not only affects the photosynthesis of plants effectively, but also easily become a hotbed of mite pests such as earthworms and wintering winter moths, breeding plants in the coming year.
