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。
Taking winter cherry as test material and N, P, K three factors and three levels L9 (34) orthogonal design method, the effect of different substrate seedling stage fertilization on winter cherry height and ground diameter increment was studied. Discuss the best fertilizer combination and fertilizer amount of different substrates of winter cherry. The results showed that the monthly increment of seedling height and diameter of each combination of fertilization treatments in red soil matrix was higher than that in the treatments of Eupatorium adenophorum substrate. Between the two fertilization treatments of two different substrates, (P = 0.000 <0.01). The fertilization effect of Eupatorium adenophorum was better than that of red soil matrix. The combination of N1P1K1 and N1P4K4 in different fertilization treatments of red soil matrix was better than that of Eupatorium adenophorum, The combination of N2P4K1 and N2P2K4 was the best. The combination of N2P4K1, N2P2K4, N1P1K1 and N1P4K4 was the most effective combination.
