摘要
与传统的等行种植甘蔗(对照)相比,采用分带和宽窄行种植甘蔗,能提高甘蔗分蘖期的硝酸还原酶活性,提高伸长期的酸性转化酶活性及光合强度,提高成熟期中性转化酶活性,能促进甘蔗成熟及提高蔗糖分,亩蔗茎产量增加40%～45%。
As compared with the conventional equal-row planting of sugarcane, the strip cropping with wide-narrow row planting increased activities of NRA at fillering stage, acid invertase at elongating stage, and neutral invertase at maturing stage, and strengthened the photosynthetic rate at elongating stage, and enhanced the sucrose content in stalks at early maturation stage, and yield of millable canes per mu by 40%—45%.
