蔗地土壤改良对甘蔗生长的研究初探

The Effect of Soil Remediation on Sugarcane Yield and Sugar Content

长期连作和大量施用化肥、农药,不施或少施有机肥是造成土壤板结、沙化、酸化,土壤有毒有害物质积累增多,导致土壤功能失调,影响作物产量和质量的归因。本试验通过采取深耕深松、增施有机肥、增加微生物菌类措施,逐步改良土壤功能,为甘蔗生长提供良好的生长环境,从而促进甘蔗增产增糖。试验结果表明,蔗田土壤改良处理单产分别为99.07、103.51 t/hm^(2),产量分别比对照平均86.03 t/hm^(2)增产13.04、17.48 t/hm^(2),增产幅度15.75%~20.31%,增产效果较好。但经方差分析未达到显著水平。蔗田土壤改良处理糖分为14.75%、15.07%,分别比对照13.94%提高了0.81、1.13个百分点(绝对值)。

Long-term continuous cropping and large-scale application of chemical fertilizer and pesticide,no or less application of organic fertilizer was the cause of soil compaction,desertification,acidification,accumulation of toxic and harmful substances in soil,resulting in soil dysfunction,affecting crop yield and quality.In this experiment,we tried to restore the soil function step by step,and provided a good growing environment for the growth of sugarcane,so as to promote the yield and sugar of sugarcane.The results showed that the yield per unit area was 99.07 and 103.51 t/hm^(2),the yield increased by 13.04,17.48 t/hm^(2),the yield increased by 15.75%~20.31%.However,the analysis of variance did not reach significant level.The sugar content of soil remediation was 14.75%,15.07%,0.81%and 1.13%(absolute value)higher than that of control(13.94%).
