摘 要 ：本文试用生态场的思想,对林网中玉米(Zeamays)的主要产量性状和质量性状与生态场内主要生态因子的关系进行了探讨。研究结果表明:林网生态场对玉米产量性状、质量性状的影响因各因子的场量和玉米的生育阶段而异。开花期前较高的温度、开花期后较低的地温、最热季节不过高的温度,以及整个生长季中较高的空气湿度是提高玉米生物学产量,穗产量、籽粒产量以及籽粒中粗蛋白积累量必要的生态条件。玉米籽粒中粗脂肪含量主要受乳熟期以前生态场的影响,龙其在穗分化、形成期需较高的空气湿度和较低的地面温度。淀粉含量受生态场的影响较小,所需生态条件是拔节一蜡熟期较低的地温。总之,各时期生态场的性质均可在玉米最终的产量和质量性状中反映出来。

Abstract:Based on the concept of ecological field(ecofield), the relationship among the main characters of yiteld and quality of corn(Zea mays)and the ecological factors in a shelterbelt network ecofield were studied in this papar. Result showed that. In shelterbelt network ecofield,the effects of various ecological factors on the characters of yield and quality of corn varied in accordance with the field quanlity and the growth/development stage of corn. Higher temperature before the florescen.se ,and lower soil te...
