配方施肥对香蕉生物量及养分积累的影响

为探究配方施肥对香蕉植株生物量、各器官养分积累量及养分积累规律，对巴西蕉施肥后，彻底刨根、分解取样研究，得出香蕉生物量及各元素含量。结果表明：配方肥处理各元素吸收大小规律为K＞Si＞N＞Ca＞Mn＞Mg＞P＞Fe＞Zn＞B＞Cu。与常规施肥相比，配方施肥可增加香蕉生物量约69.47%，平均每株可增加N、P、K、Ca、Mg、Mn、Fe、Cu、Zn、B、Si约75.98%、63.71%、5.07%、49.39%、82.85%、26.60%、76.24%、44.49%、152.50%、162.22%、81.18%。配方施肥能有效促进植株生长，提高果实和叶片养分积累，为科学制定香蕉养分综合管理技术提供参考。

Effect of fertilizer on biomass and nutrient accumulation of banana

To explore the biomass and nutrient accumulation and accumulation law of fertilizer on banana, taking Brazil banana for example, get all body and divide them out, then get the biomass and nutrient of banana plant. The results showed that, the order of nutrient contents was K> Si> N> Ca> Mn> Mg> P> Fe> Zn> B> Cu. Compared with convention, fertilization could increase banana biomass, nearly 69.47%; could respectively increase accumulate nitrogen fertilizer 63.68%, phosphorus 64.12%g, potassium 5.07%, calcium 49.39%, magnesium 82.85%, manganese 26.60%, iron 76.24%, copper 44.49%, zinc 152.50%, boron 162.22%, silicon 81.18% per plant. The result showed fertilization can promote plant growth, increase nutrient accumulation of fruit and leaf, making suggestion for nutrient management scientifically of banana.
