不同施肥处理对山地白皮松生长的影响

Effect of Fertilization Treatment on Growth of Pinus Bungeana Zuuc. ex Endl

以9年生的白皮松苗木为研究对象,针对一个生长周期内的不同类型施肥处理的白皮松在一个生长周期内的树高、地径和生长量的变化。结果表明,不同施肥处理下白皮松树高、地径、新稍长差异性显著,每株施用N肥100 g、P肥45 g和K肥80 g的组合配方,以及施用农家肥180 g或者复合肥60 g的处理组的白皮松树高、地径和新稍生长量均高于其他处理组。

This article mainly talks about 9 years nursery stock of Pinus bungeana Zuuc, we measured three growth factors, such as tree height, ground diameter and new shoot length in one growth cycle. The experiment result shows that fertilization treatment has significant influences on three growth factors, tree height, ground diameter and new shoot length. The three growth factors of optimal combination（N100g, P45 g and K80 g per tree）, farmyard manure（180g per tree） and compound fertilizer（60g per tree） groups were all higher than other treatments group.
