坡岗地宿根糖蔗营养调控措施研究初报

Preliminary study on nutritional regulating techniques for upland ratoon sugarcane

通过田间试验研究了坡岗地宿根蔗营养调控技术。结果表明,单独施用配方肥、缓/控释配方肥,或配方肥配施有机肥、中微肥、调理剂的营养调控措施均可促进宿根蔗植株生长,蔗茎增高增粗,实现产量提高、品质优化目标;其中,配方肥配施有机肥、中微肥、调理剂的调控措施增产显著,应用配方肥配施中微肥营养调控措施的甘蔗品质最好。因此,在南方坡岗地糖蔗生产中,建立以配方肥配施中微肥、有机肥或调理剂为主体的"专用营养+土壤改良"调控技术具有积极的推广意义。

A field trail on upland were conducted to study the nutritional regulating techniques for ratoon sugarcane at WengYuan country in 2009. It was found that nutritional regulating techniques, result in improvement in plant height, stem length, stem diameter, internode length,and finally increased the yield and quality of the sugarcane harvested; specific-fertilizer combination with manure, with mediun and micro nutrients or with regulator significantly increased the yield; we also found that specific-fertilizer combination with medium and micronutrient was the best way to improve ratoon cassava’s quality. So,the best regulating techniques for ratoon sugarcane growing on upland were specific-fertilizer combination with manure, medium and micronutrient or with regulator.
