摘要
采用设置5个试验区、12个处理,每个处理重复3次,以无灌溉处理作为对比的试验方法研究固定灌溉定额下不固定灌溉次数对糖料蔗生长的影响,分析不同灌溉次数对糖料蔗株高、茎粗、叶面积、有效茎数、产量和锤度等的测试结果,确定适合甘蔗生长的灌溉次数,最终得出萌芽~幼苗期灌3次,伸长期灌6次生长效应较好的结论。
Comparative experiments were conducted on the influence of controlling irrigation times on sugarcane growth in 12 selected sites from 5 experimenting areas, with three repetitive treatments under a fixed irrigation quota. No irrigation scenario is adopted for comparison with test results under various irrigation times, such as stem height, stem diameter, leaf area, number of productive tiller, yield and brix degree. It helps to finalize the irrigation scheduling that suits to the growth of sugarcane, i.e. three times in sprouting and seedling period and six times in elongation stage.
