【摘要】 【目的】分析研究植物占位空间营养及其调控。【方法】以4种不同玉米田间种植型式为素材,采用系统分析的方法。【结果】群体作物密植过程中,植物占位立体空间与光、热、水、气（CO₂）、肥（矿质元素）同是植物生长发育并获得较高群体产量必需的生活要素;是植物存活和生长发育冠层营养和土体营养的承载依托;可以用植物单株内切圆面积或单株内切圆冠层和根系土体的圆柱体体积大小对群体作物的营养状况进行量化比较。【结论】人类可通过对植物田间株、行距调节和不同田间配置对其加以调控、改变更多还原

【Abstract】 [Objective]Study plant occupying stereo nutrition.[Method]Take 3 different maize distributing model in field as the material by system analysis.[ResultjThe occupying stereo space of plant,light,heat,water,gas（CO₂） and fertilizer（mineral elements） were essential elements of plant growth and high population yield.They were also the basement of plant survival,growth canopy nutrition and soil nutrition.Through quantization compared by multi-shaped rod regarding area or canopy multi-shaped rod regarding of single plant and Cylinder size of root soil.[Conclusion]plant occupying stereo nutrition can be regulated by changing the row spacing and plant spacing of plants in the filed.更多还原
