| 为探究不同种植模式对作物生理特性及根系形态特征的影响，本试验以玉米‖棉花为研究对象，试验设置3种种植模式处理，分别为单作玉米、单作棉花、玉米‖棉花。通过对作物株高、叶绿素含量、田间温湿度、根系长度变化及产量等的测定，探究不同种植模式下作物的生长状况及土地当量比。结果表明：单作玉米功能叶叶片平均SPAD值高于间作6.78%，间作棉花功能叶叶片平均SPAD值高于单作1.12%。玉米间作株高平均增长率为83%，单作平均增长率为82.9%，表明了玉米间作模式更有利于株高的增长；单、间作玉米田间温度分别为30.9℃、32.47℃；单、间作棉花田间温度分别为31.6℃、32.95℃，间作模式在一定程度影响根系分布，不同土层间作作物根长显著增加4.7%。 |

| To explore the effects of different planting patterns on physiological characteristics and root morphological characteristics of the crops, in this experiment, monoculture and intercropping maize cotton were selected as the research objects. The experiment was carried out in three planting modes including monoculture crop corn, monoculture crop cotton, intercropped corn and cotton. By measuring the physiological characteristics, chlorophyll content, root characteristics, field temperature, humidity and yield of crops, the crop growth and land equivalent ratio under different planting modes were explored. The results showed that the SPAD value of maize functional leaf was 6.78% higher than that of intercropping and 1.12% higher than that of cotton functional leaf under intercropping. The average growth rate of maize intercropping was 83%, and the average growth rate of monoculture crop was 82.9%, indicating that the maize intercropping model was more conducive to plant height growth. The field temperatures of maize and intercropped cotton were 30.9℃ and 32.47℃, respectively. The field temperatures of cotton and intercropped cotton were 31.6℃ and 32.95℃, respectively. The intercropping pattern affected the root distribution to a certain extent, and the crop root length significantly increased by 4.7% in the middle of different soil layers. |
