| 摘 要： | 为研究一串红苗期营养特性和控释肥在穴盘育苗中的应用效果,对一串红穴盘苗进行了氮、磷、钾营养特性和控释肥肥效试验.结果表明:一串红穴盘苗氮素的含量平均为2.7513%、磷0.5370%、钾0.8513%,苗期N、P、K平均相对吸收量之比为1:0.195:0.309,随着幼苗生长,氮变化幅度不大,磷逐渐下降,钾呈上升趋势.控释肥能够明显增加一串红穴盘苗的株高、叶面积、叶绿素、生物量和提高幼苗质量,根据壮苗指标综合评定,该试验以控释肥用量为纯氮40.00g/kg、纯磷6.99g/kg、纯钾16.60 g/kg效果最好.

| Abstract: | N,P,K nutritional characteristics and the effects of controlled-release fertilizer applied in plug-seedling with medium of scarlet sage were studied.The controlled-release fertilizer(20-8-10) was used to study the feasibility of it on plug-seedling and the optimum amount.And the different effects between general fertilizer and controlled-release fertilizer were studied.The results showed that: the content of nitrogen,phosphorus and potassium had not significant difference in prophase,after that the nitrogen... |
