兰是喜干恶湿的半气生根植物,具有嗜气的生理特性。因此养兰基质我选择质轻、蓄水、保湿性能好,易消毒的木炭、蛭石、草炭等。配比为木炭70％,蛭石20％、草炭土10％。基质使用前进行筛选、去杂。其粒度分为1—3毫米和3—5毫米两级。为了改善兰盆的透气性还必须加大瓦盆排水孔的直径,根据盆的大小,每盆的排水孔1—5个。直径3—5厘米。栽植前对基质、兰株和花盆进行消毒。消毒方法是用自来水冲洗,去掉基质中的泥土,再用水煮(80—100℃)半个小时,处理后凉于待用。兰
Orchid is a sweet and humid half-air rooting plants, with the physiological characteristics of the gas. Therefore, I choose medium substrate orchid light, water, moisturizing performance, easy to disinfect charcoal, vermiculite, peat and so on. The ratio of 70% charcoal, vermiculite 20%, peat soil 10%. Matrix screening before use, to miscellaneous. Its particle size is divided into 1-3 mm and 3-5 mm two levels. In order to improve the permeability of the blue basin must also increase the diameter of tile drainage holes, according to the size of the basin, drainage holes per basin 1-5. 3-5 cm in diameter. Before planting, sterilize the substrate, blue plants and pots. Disinfection method is to rinse with tap water, remove the soil in the matrix, and then boiled (80-100 ℃) for half an hour, after treatment cool to stand. Blue
