摘要
在湛江蔗区,对甘蔗新品种粤糖00-236和当地主栽培品种ROC10进行不同植期、不同下种量及不同施肥水平的试验。结果表明,提早植期和增施磷肥有显著的增产增糖效果。粤糖00-236的平均蔗茎产量与ROC10相近,但其公顷含糖量极显著高于后者。粤糖00-236特早熟高糖,适合糖厂早期开榨。在本试验条件下,公顷下种量45000段与37500段双芽苗之间、公顷尿素施用量1050kg与750kg之间,以及公顷氯化钾施用量600kg与450kg,蔗茎产量和含糖量均无显著差异。
Field experiment on different planting times, planting densities and the application rates of N, P, and K fertilizers for the sugarcane variety YT00-236 and ROC10 was conducted in Zhanjiang cane area, Guangdong province. The results indicated that for both varieties under test, earlier plating and higher phosphorus fertilizer application resulted in higher cane and sugar yields significantly. YT00-236 produced just about the same level of cane yield as, but significantly higher sugar yield than ROC 10, which performed early maturity and high sugar content, and was suitable for providing quality millable cane for the early milling season. Under the conditions of the experiment, no remarkable differences in cane and sugar yields were found between 45000 and 37500 twobudded setts per hectare, between 1050 kg and 750 kg of urea per hectare and between 600 kg and 450 kg of potassium chloride per hectare.
