摘  要:
以冬樱花为试材,采用N、P、K三因素三水平L9(34)正交设计法,对比研究了不同基质苗期施肥处理对冬樱花苗高和地径月增量的效应,以探讨冬樱花不同基质的最佳肥料组合及施肥量。结果表明:红壤基质各施肥处理组合苗高和地径月增量均比紫茎泽兰基质各处理间的月增量大;2种不同基质10个施肥处理苗高和地径增量之间差异均达到极显著水平(P=0.000<0.01);紫茎泽兰基质施肥效应较红壤基质好,其中红壤基质不同施肥处理组合中以N1P1K1、N1P4K4组合较优,紫茎泽兰基质不同施肥处理组合中以N2P4K1、N2P2K4组合较优;施肥效应最大的组合为N2P4K1,其次为N2P2K4组合、N1P1K1组合、N1P4K4组合。

摘  要:
Taking Cerasus cerasoides as material,using N,P,K three factors and three level orthogonal design L9(34), growth increment of plant height and ground diameter of Cerasus cerasoides seedling and effect of fertilization on different substrates were compared and studied,in order to investigate the optimal combination of fertilizers and plant different substrates.The results showed that monthly increment of plant height and diameter under red soil substrate was bigger than Eupatorium breaking substrate.Plant height and ground diameter of ten substrate treatments all reached significant difference(P=0.000<0.01);fertilization effect of Eupatorium substrate was better than red soil substrate,among red soil substrate,N1P1K1and N1P4K4were better,among Eupatorium substrate,N2P4K1and N2P2K4 were better;the best fertilization effect was N2P4K1combination,followed was N2P2K4,N1P1K1and N1P4K4combinations.
