对几种重要的花卉栽培基质的理化性质进行了测定,结果表明:岩棉的通透性能很好,几乎不含有效养分、无缓冲能力。泥炭本身含有一定的养分,大小孔隙度、容重适度,总盐含量适中,有一定的缓冲能力。椰糠的总盐含量和水溶性盐含量过高,在使用前必须进行处理。泥炭、椰糠采用混合基质后,理化性质有所改善。蛭石:珍珠岩(V:V=1:1)的保水力相对较差。在生产中,除考虑基质的上述理化性质即实用性外,还必须根据经济性的原则考虑基质的选择。
The physical and chemical properties of several important flower cultivars were determined. The results showed that the rock wool had good permeability, almost no effective nutrients and no buffering capacity. Peat itself contains a certain amount of nutrients, the size of porosity, bulk density, the total salt content is moderate, have a certain buffering capacity. The total salt content of coco peat and water-soluble salt content is too high, must be dealt with before use. The physical and chemical properties of peat and coconut bran have been improved with the mixed matrix. Vermiculite: perlite (V: V = 1: 1), the water retention is relatively poor. In production, in addition to consider the physical and chemical properties of the substrate that is practical, but also must be based on the principle of economy to consider the choice of substrate.
