摘　　要：通过对瓜棉复合种植与单作瓜、单作棉的个体和群体生长动态及光合特性比较分析,结果表明:采取合理的栽培管理方式,瓜棉复合种植可建立良好的作物群体结构,对瓜的正常生长发育影响不大,可以获得与单作瓜相近的瓜产量;复合种植模式的棉花植株生长优于单作棉花,棉花增产。在各生长阶段,复合种植模式的田间叶面积指数、光合势和群体生长率均优于单作瓜和单作棉。瓜棉复合种植可以有效地改善田间小气候,降低温度,增加相对湿度,提高净光合速率。从而有效提高了光能利用率,全年的综合产量增加。The individual growth, colony, growth developments and the photosynthetic characteristics of the melon and cotton complex planting and monocuhure melon and cotton were compared and analyzed. The results indicated that：adopted reasonable planting and management methods, under the melon and cotton complex planting condition, the better crop colony framework could be harvested. The melon normal upgrowth was not influenced badly and the same yield could be got as the monoculmre melon. The cotton plant growth by complex planting was better than that by monoculmre planting. So the high yield of cotton could be got by the complex planting. The field leaf area index, the photosynthesis force and the colony growth rate of the melon and cotton by complex planting modes were better than those of the monoculture melon and monoculture cotton. The field microclimate was improved effectively under the melon and cotton complex planting condition. The field temperature was reduced, the relative humidity was increased and the net photosynthesis rate was enhanced. That could effectively improve the light utilization ratio. So the compositive yield could increase.
