摘要: 为了筛选出适宜玉米高产高效种植的耕作和施肥方式,以先玉696为材料开展田间定位试验,对比分析耕作方式与施肥方式对春玉米光合特性的作用效果。结果表明:深松(SS)与控释肥(CN)较浅旋(RT)和化肥(HY)相比,能进一步使春玉米的光合特性及产量得到提升。不同耕作和施肥方式的各处理间净光合速率表现为:SS-CN>RT-CN>SS-HY>RT-HY>SS-CK>RT-CK。其中,SS-CN各生育期的干物质积累量分别较RT-HY、RT-CN、SS-HY提高7.05%~38.84%,叶面积指数提高2.34%~21.33%,净光合速率提高2.80%~20.58%,叶绿素相对含量增加1.48%~24.18%。SS-CN产量较RT-HY、RT-CN、SS-HY提高7.94%~22.43%。因此,深松配施控释肥是适宜玉米高产高效种植的耕作和施肥方式。

Abstract: To select suitable cultivation and fertilization methods for high-yield and high-efficiency planting of maize,the field positioning experiment was carried out with Xianyu 696.The effect and relationship of the tillage method and the controlled-release fertilizer on the photosynthetic characteristics of spring maize were compared and analyzed.The results showed that compared with the chemical fertilizer,the controlled-release fertilizer could promote the photosynthetic characteristics and yield of maize.The net photosynthetic rate of different tillage and fertilization methods was shown as SS-CN>RT-CN>SS-HY>RT-HY>SS-CK>RT-CK.Compared with RT-HY,RT-CN,and SS-HY at different growth stages,SS-CN was shown to have the dry matter increased by 7.05%-38.84%,the leaf area index increased by 2.34%-21.33%,the net photosynthetic rate increased by 2.80%-20.58%,the relative content of chlorophyll increased by 1.48%-24.18%,and the yield was 7.94%-22.43% higher than that of each treatment.Deep pine combined with the controlled-release fertilizer is a suitable tillage and fertilization method for high-yield and high-efficiency maize planting.
