不同施肥量对柑橘容器苗生长发育的影响

Influences of Different Fertilizer Rates on the Growth of Citrus Container Seedling

进行了不同施肥量对柑橘容器苗生长发育影响试验。结果表明,合理施肥能够促进苗木增高、加粗、主根加长和促发须根,还能够显著增加苗木抽二次梢、三次梢和四次梢以及二至四次梢的总生长量、总叶片数和总发生量。其中总体上处理效果最好的是每株施用0.5%尿素液0.5kg的处理,其次是每株施用0.5%过磷酸钙液0.5kg的处理,且施肥处理总体优于不施肥处理。

The effects of the different rates of fertilizer application on citrus container seedling growth were studied.The results showed that the reasonable application of fertilizer promoted roots growth, increased height and diameters of plants, significantly increased the branch numbers, total leaf number and total growth amount.The effect of treatment by 0.5kg 0.5% Urea per plant was best, followed by treatment by 0.5kg 0.5% ssp.The effects of all treatments were significantly superior to that of control.
