高效速溶硼肥在油菜上的施用效果初报

Effect of Highly Efficient Instant Boron Fertilizer Applied to Rapeseed

缺硼土壤种植油菜时施用高效速溶硼肥比施用硼砂可显著增强油莱生长势、优化产量结构、改良油菜籽品质,增产1.71％～10.6％;比不施硼极显著增产,增幅达21.17％～26.04％。高效速溶硼肥的三种施用方式即基施+喷施、基施、喷施肥效差异不显著。从生态效益和经济效益综合分析、以苔期喷施0.15％的高效速溶硼肥效果较好。

In deficient boron soil, when rapeseed was applied highly efficient instant boron fertilize, its growth vigour and yield structure and the trait were all further developed and improved than borate.and yield might add 1. 71%-10. 6%. Yield range increased reached to 21: 17%-26. 04% than no boron fertilizer was applied. Three methods for applying highly efficient instant boron fertilizer were applying in soil+spring application and applying in soil and spring application, and no obvious effect difference was found among them. Through comprehensive analysis from ecological benefit and economic benefit,the effect that highly efficient instant boron fertilizer was springed before stem elongation was better.
