| 摘 要： | 对红松S1-0播种苗进行正交施肥试验,研究基肥、追肥(氮、磷)对苗木生长的影响,探讨苗木最佳施肥配比。结果表明:各肥料因子对苗木生长影响排序为追肥尿素﹥基肥﹥追肥过磷酸钙,促进红松S1-0播种苗木生长最佳肥料用量为每平米以腐熟猪粪2 500 g、过磷酸钙22 g、尿素3 g或腐熟猪粪2 500 g、过磷酸钙22 g、尿素3 g、硫酸钾12 g作为基肥,108 g或78 g过磷酸钙和44 g尿素为追肥,分四次追施。

| Abstract: | The effect of base fertilizer, topdressing( N,P) on seedling growth was researched and nursery stock optimun fer-tilization ratio was discussed by carrying orthogonality fertilizer test to Pinus koraiensis S1-0 sowing seedling.The result showed that the arrange of the effect of each fertilization factorson seedling growth was topdressing urea>base fertilizer>topdressing superphosphate.The best fertilizer rate of promoting Pinus koraiensis S1-0 sowing seedling was decomposed pig manure 2 500 g, superphosphate 22 g,urea 3 g or decomposed pig manure 2 500 g, superphosphate 22 g,urea 3 g, potassi-um sulphate 12 g as base fertilizer per square meter.And it was taken 108 g or 78 g superphosphate and 44 g urea as top-dressing which applied for 4 times. |
