化学调控剂与钾肥互作对辽南地区玉米形态指标及产量的影响OA北大核心CSCDCSTPCD
Effect of the Interaction between Chemical Regulators and Potassium Fertilizer on Morphological Index and Yield of Maize in Southern Liaoning Province
以高秆大穗型品种丹玉202为试验材料,研究4种不同化学调控剂与4种不同剂量钾肥互作对辽南地区玉米形态指标及产量的影响.结果表明,玉米壮丰灵与4种不同剂量钾肥互作均有效降低玉米植株高度、增加气生根层数；玉皇V8与4种不同剂量钾肥互作均有效缩短玉米节间距离、增加茎粗、降低玉米倒伏率和倒折率；处理组合K2SO4 112.5 kg/hm2+玉米壮丰灵产量最高为11 120.40 kg/hm2.
Using Danyu202 as experimental materials, we studied the effect of the interaction of four kinds of different chemical regulators and four kinds of different dose of potassium fertilizer on morphological index and yield of maize in southern Liaoning Province. The result indicated that the Corn Zhuangfengling interacted with four kinds of different dose of potassium fertilizer could effectively decrease plant height, increase layer number of aerial root; the …查看全部>>
