摘要
采用6.0m(A)和4.8m(B)分带宽窄行种植的甘蔗群体由于能充分发挥边行优势的作用,A、B 两处理亩有效苗、茎数比对照(C)多;叶面积指数亦大2倍以上;群体内光能分布增加,在宽窄行 A 和 B>C,但在窄行则相反,即 C>A 和 B,这种结构为蔗地全年间种作物创造了良好的光照条件。
Sugarcane Population of strip planting with wide-narrow-rows of 6.0m (treatment A) and 4.8m (treatment B) strip width appeared the border effect. As compared with the control,i.e.,normal planting (treatment C),the numbre of millable cane of treatment A and B increased,whill the LAI increased by 2 times.Sugarcane population gained more light energy as the relative light intensity in the wide rows was higher than that in the control although the relative light intensity in the narrow rows did the opposite. This cropping system could provid more tight energy for interplanting crops in the sugarcane field.
