不同肥料对蓝花楹幼树生长量的影响试验

摘要

Experiment of five different fertilizers on Jacaranda mirnosifoia sapling growth was carried out in Baoshan of Yunanan province. The results showed that treatment A ( sheep dung 200g / plant) had the best influence on tree height and growth volume of DBH , followed by NPK fertilizer, cow flung, the worst is the treatment F (control, no fertilizer)- The tree height and growth volume of DBH with treatment A were higher 82. 6% and 44. 7% than treatment F ( ronlrol) respectively. There was a significant difference between the different fertilizer treatments.%在云南保山市施甸县开展了5种不同肥料对蓝花楹幼树生长量的影响试验.结果表明,树高、胸径的生长量均以A处理(羊粪200 g/株)为最好,其次是氮磷钾复合肥,再次是牛粪,最差的是F(对照,不施肥)处理.A处理在树高和胸径生长量上分别高出F(对照)处理的82.6％和44.7％.不同肥料处理间存在极显著差异.
