| 摘 要： | 以新台糖22号（ROC22）为试验材料，在采用地膜覆盖、深耕深松、化学调控等集成技术条件下比较不同下种方式和种植密度对旱坡地甘蔗群体结构、产量及品质的影响。结果表明，在旱坡地上，新台糖22号采用蔗梢（尾）不砍种方式以97500芽／ha下种量效果最好，可显著提高甘蔗出苗率，促进早期分蘖，降低螟害枯心率，优化群体结构，有较高的产量和糖分，同时有利于宿根蔗发株。

| Abstract: | The effects of different planting methods and planting densities on yield,quality and economic traits of sugarcane population were studied.Variety ROC22 was used as experimental material under integrated technical conditions,viz.,plastic mulching,deep ploughing and deep scarification,chemical regulation,etc.The results revealed that the method of cane shoot planting without cutting cane tip with planting density of 97500 buds / ha was the best in arid hillside fields,it could significantly increase the germ... |
