摘要:
为了明确桂糖32号最优高产栽培模式,本试验采用裂区设计,探索不同施肥量、种植密度对桂糖32号的甘蔗蔗糖分和产量的影响。结果表明,施肥量对桂糖32号蔗糖分影响较小,种植密度对桂糖32号蔗糖分影响较大,中高密度处理下的蔗糖分最高。肥料和密度的互作效应对蔗糖分影响较大,中肥中高密度处理下的蔗糖分最高。不同施肥量处理对桂糖32号产量影响显著,不同密度处理对产量影响不显著。肥料和密度的互作效应对桂糖32号产量影响显著,高肥中高密度处理下产量最高,肥料和密度的互作效应对桂糖32号经济效益影响明显,中肥低密度处理下经济效益最高。桂糖32号的高产高效栽培模式是:中肥(N:241.5 kg/hm2,P2O5:270.0 kg/hm2,K2O:135.0 kg/hm2)低密度(1 hm275 000芽)处理。
Abstract:
To explore the optimal cultivation pattern of sugarcane Guitang32, experiments with two-factor split block design were carried out to analyze the changes of sucrose content and yields at different fertilization levels and planting densities. The fertilization levels barely influenced the sucrose content which however was significantly affected by planting densities. Medium-high planting density presented the higher sucrose content. The interaction between fertilizer and densities showed a great effect on the sucrose content, which was higher in medium-high density treatments. Unlike planting density, the fertilization levels exhibited great effects on Guitang 32 yield. The sugarcane yield was the highest under high fertilization and medium planting density. High-yielding cultivation of Guitang32 was suggested to apply the medium fertilization of N 241.5 kg/hm2, P2O5 270.0 kg/hm2, K2O 135.0 kg/hm2 and the low planting density of 75 000 buds per hectare.
