摘要
以普通玉米龙单13、绥玉7号、四早113为试验材料,在玉米专用肥施用量不同的处理下,通过对株高、叶面积、叶绿素含量、蛋白质、淀粉及产量等的测定分析,研究玉米专用肥施用量对玉米生长发育、品质、产量的影响规律,为玉米科学施肥提供理论依据,丰富玉米生理基础。结果表明:最佳玉米专用肥用量为525 kg.hm-2,施用过高反而降低玉米的产量和品质。
Taking the ordinary maize Longdan13,Suiyu No.7,Sizao113 as test materials,dealing with different amount of maize-specialty fertilizer,through the determination and analysis on plant height,leaf area,chlorophyll content,protein,starch,and the yield,the effect of maize-specific fertilizer on maize growth and development,quality,yield of the law were studied.It could provide the theoretical basis of scientific fertilization,the physiological basis of the wealth for the maize study.The results showed that the optimal amount of maize-specialty fertilizer was 525 kg·hm-2,more than which could decrease the yield and the quality.
