摘要
通过木槿容器苗栽培试验,研究了控释肥、控释肥+少量普通复合肥(BB肥)、普通复合肥、营养液对菇渣基质电导率及木槿苗叶片数、枝条长度、最大叶面积、叶绿素含量、植株鲜重等生长指标的影响。结果表明:普通肥料处理前期菇渣基质电导率过高,后期电导率偏低,木槿容器苗生长不理想;控释肥处理前期菇渣基质EC值稍低,但后期木槿各项生长指标与营养液处理相当;控释肥加入少量普通复合肥制成的BB肥,养分释放与木槿容器苗的养分需求基本一致,木槿生长总体优于其他施肥处理。控释肥施肥方法简单,效果理想,是基质容器育苗值得推广的一种施肥方法。
Hibiscus Syriacus container seedlings experiment was carried out to study the effects of controlled-release fertilizer, controlled-release and little common compound fertilizer, common compound fertilizer, nutrient solution on electrical conductivity of spent mushroom compost substrate, and on growth indexes of Hibiscus Syriacus, such as leaf number,shoot length,maximum leaf area,chlorophyll content,fresh weight of the whole plant,etc. The results indicated that the EC values of spent mushroom compost substrate of common compound fertilizer treatment were too high in the prior period,and the EC values were low in the later period,the growth of Hibiscus Syriacus container seedlings were undesirable. The EC values of spent mushroom compost substrate of controlled-release fertilizer treatment were slightly low at the beginning, but it's growth indexes of Hibiscus Syriacus were equivalent with nutrient solution treatment in the later growing period. The BB fertilizer was made of controlled-release and little common compound fertilizer, which nutrient release was basically consistent with nutrient demand of Hibiscus Syriacus container seedlings, and the growth of Hibiscus Syriacus was better than other treatment. Fertilizing method of controlled-release fertilizer was easy, and effect was ideal, so it was a good fertilizing method of container seedlings with growing media and should be promoted.
