摘要
针对新疆吐鲁番地区普遍采用的瓜棉复合种植模式与单作甜瓜、棉花的个体和群体生长动态进行了比较研究。结果表明:采取合理的栽培管理方式,瓜棉复合种植并不影响甜瓜的正常生长发育,可以获得与单作甜瓜相近的产量。复合种植棉花与单作棉花比较,共生期内棉花植株的生长优于单作棉花;由于前期奠定了良好的生长基础,甜瓜收获后复合种植棉花个体、群体生长状态远优于单作棉花。瓜棉复合种植可建立良好的作物群体结构,在各生长发育期,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甜瓜和单作棉花,可有效提高光能利用率。
Intercropping of melon and cotton is a common practice in Turpan area. This study investigated melon growth and development intereropping with cotton. Under good crop management,intercropping did not affect the growth and development of melon plants and population. Similar yield of melon was achieved under the intercropping system compared to monoculture. The cotton plants under intercropping grown and developed better, during intereropping period, than the plants under monocuhure. Better plant and population development of cotton crop were observed after the harvest of melon crop, due to the better plant and population development at early stage. Under the melon and cotton intercroping condition, the crop population development,field leaf area index, photosynthesis potential and population growth rate of the melon and cotton were better than those of the monoculture melon and cotton. This intercropping system could effectively improve the light utilization.
