| 摘 要： | 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180kg/hm2时配施15kg/hm2硫酸锌,产量最高达9581.2kg/hm2。经回归拟合,单施磷肥和磷锌配施的最佳施P2O5量分别为178.65kg/hm2和203.49kg/hm2,籽粒产量可达8823.0kg/hm2和9499.61kg/hm2。因此,在施氮基础上,配施磷或磷锌可促进夏玉米生长发育,实现高产抗逆高效栽培。

| Abstract: | 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 disease resistance, and the effect of phosphorus and ... |
