摘要: 为进一步探明种肥对玉米免耕精密播种的作用,2013 年运用大田2 点试验,测定生理与产量指标,研究了5 种处理(NPK、NP、NK、PK、CK)的种肥对夏玉米免耕精密播种的影响。NPK种肥处理后的夏玉米的幼苗素质、根干重、根体积、根条数、叶片Pn和SPAD值都最好,进而降低了玉米果穗的秃尖长,增加了玉米的穗长、穗行数、行粒数、千粒重。NPK处理的产量比处理NP、NK和PK、CK增产4.52%、6.06%、13.21%和29.05%,增产效果大于其他施用组合。种肥影响夏玉米免耕精密播种的效果,且N、P、K都是夏玉米免耕精密播种种肥必不可少的营养成分。

Abstract: The aim was to explore the effect of seed manure on no-tilling and precision sowing summer maize. Two field tests with five treatments (NPK, NP, NK, PK and CK) of seed manure were conducted to determine the physiological parameters and yield index in 2013. Under the treatment of NPK seed manure, the seedling quality, root dry weight, root volume, root number, leaf Pn and SPAD were all the best, thus reduced the bald tip of maize ear length, increased the maize ear length, ear row number, row grain number, and 1000 kernel weight. The yield of NPK treatment increased by 4.52%, 6.06%, 13.21% and 29.05% in comparing with that of treatment NP, NK, PK, CK, respectively. The yield-increasing effect of NPK treatment was greater than that of the other fertilizer combinations. Seed manure affected seeding effect of no- tilling and precision sowing summer maize. At the same time, N, P and K were essential nutrients of seed manure for no-till and precision sowing summer maize.
