Effects of Phosphorus Applied Amount and Phosphorus-Zinc Combination on Growth and Kernel Yield of Summer Maize
为更好探索小麦/玉米一年两熟种植制度下,夏玉米施肥制度,实现夏玉米抗逆高产丰产。采用裂区设计,对施磷量及磷锌配施对夏玉米生长发育及籽粒产量的影响进行研究。结果表明：单施磷肥或磷锌配施促进夏玉米生长发育,增加干物质积累和次生根数,降低秃尖、改善穗部性状、提高抗病能,且配施效果优于单施磷肥。单施磷较对照增产幅度为7.70%~31.21%,配施增产15.99%~40.34%,磷锌配施较单施磷肥增产幅度达4.03%~8.73%。其中以施P2O5量在180…查看全部>>
The purpose of this paper was to investigate the effects of phosphorus and phosphorus-zinc combination on growth and development and kernel yield of a summer maize variety Xianyu 335 by split block design in Linfen, Shanxi, China. Phosphate fertilizer application alone or phosphorus-zinc combination could promote the growth and development of summer maize, increase dry matter accumulation and secondary root number, reduce bare tip, improve cob traits and dis…查看全部>>
