摘要
为探索施用腐殖酸类肥料对碱性植烟土壤pH及烤烟产质量影响,2005年在河南许昌烟区进行了腐植酸复合肥施用量(0、150、300、600kg/hm2)的4个不同施用量的肥料田间试验,试验结果表明:施用腐殖酸类肥料可降低土壤的pH值,施用量愈大,降低幅度愈大,同时土壤的有机质、速效氮、速效磷、速效钾升高,土壤容重下降;施用腐殖酸复合肥不影响烟株前期发育,但会推迟成熟期,施用300～600kg/hm2腐殖酸复合肥烟株农艺性状较好,烟叶的经济性状较好;施用适量300kg/hm2腐殖酸复合肥烟叶主要化学成分较协调、评吸质量较好。综合降土壤pH值效果及烟叶生长、农艺性状、产质量情况,在豫中碱性植烟土壤环境,建议腐殖酸复合肥施用量为300kg/hm2。
To explore the effect of humus fertilizer on alkaline tobacco-planting soil pH,tobacco yield and quality,the application rate of humus acid compound fertilizer were divided into four experimental treatments（0、150、300、600 kg/hm^2） in 2005. The results showed that pH value of tobacco-planting soil could be decreased through the application of humus fertilizer,the more humus fertilizer used,the more pH value of tobacco-planting soil decreased,at the same time,there is a increasing trend in soil of the organic matter,available nitrogen,available phosphorus and available potassium but soil capacity dropped; there is no negative effect of the application of humus acid compound fertilizer on prophase growth of flue-cured tobacco,but its maturation is postponement. While the application rate of humus acid compound fertilizer is between 300㎏/hm^2 and 600㎏/hm^2,the economic character and agronomy character of tobacco is better,the application rate of humus acid compound fertilizer is 300㎏/hm^2,chemical composition of tobacco is coordinate and sense organ quality is better. According to the research results,the best application amount of humus acid compound fertilizer is 300㎏/hm^2 in alkaline tobacco-planting soil of central Henan tobacco-growing areas.
