俗话说:良好的开端是成功的一半。栽培基质的选择就是必须讲究的开端。良好的基质不仅决定成品的质量,还可减轻后期的管理,很多情况都是没选好基质的结果。很难具体说明最适合一品红生长的基质组成和配比等情况,但所选基质的物化性质应达到如下标准:1、良好的透气性、排水性和合适的持水能力透气性、排水性取决于基质的孔隙度和大小孔隙比。总孔隙度是指介质中持水孔隙和透气孔隙的总和,它反映了介质容纳空气和水分的整体空间。一般介质的总孔隙度在60～80%,部分介质总孔隙度很大,如岩棉、蛭石等的总孔隙度在90%以上。总孔隙度大的介质比较疏松,但对植物根系固着能力差。沙子等介质的总孔隙度只有30%,介质较重。
As the saying goes: a good start is half done. The choice of cultivation matrix is the beginning of stress. Good substrate not only determines the quality of the finished product, but also reduce the late management, in many cases are not selected matrix results. Difficult to specify the most suitable for the growth of poinsettia matrix composition and ratio, etc., but the physical and chemical properties of the selected substrate should meet the following criteria: 1, good air permeability, drainage and appropriate water holding capacity of air permeability, drainage depends Porosity and size porosity in matrix. Total porosity refers to the sum of water and air voids in the media, which reflects the overall volume of the media that holds both air and moisture. The general porosity of the medium in 60 ~ 80%, part of the total porosity of the media, such as rock wool, vermiculite, such as the total porosity of 90%. The medium with large total porosity is relatively loose, but its fixation to plant roots is poor. The total porosity of sand and other media is only 30%, medium heavier.
