丹麦品氏托普基质对矮牵牛穴盘苗发芽和生长的影响

Effect of Denmark's Substrate on Germination and Growth of Petunia hybrida Seedlings

为实现矮牵牛的大规模工厂化育苗,研究了不同基质对矮牵牛种子发芽和幼苗生长的影响。结果表明:与素土和普通草炭基质相比,丹麦品氏托普基质大大地缩短了矮牵牛生育期。丹麦品氏托普基质处理下的矮牵牛发芽率、发芽势和冠幅均高于其它两种基质处理,同时,植株感病率低,杂草生长减少。

In order to achieve the large-scale factory nursery for Petunias hybrid Vilm, the effect of different substrate with pure soil,vermiculite and peat on the germination and growth of seedlings were studied and compared. The results showed that the germination rate, germination energy and canopy diameter of Petunia hybrid treated with pindstrup sphagnum were higher than pure soil and peat, the disease infection rate and weed growth rate were decreasing.
