摘要
设置有机肥与化肥不同配比的8个处理:100%有机肥、75%有机肥+25%化肥、60%有机肥+40%化肥、50%有机肥+50%化肥、40%有机肥+60%化肥、25%有机肥+75%化肥与100%化肥,并以不施肥为对照(CK),研究不同施肥处理对广藿香生长、产量、油量、品质及广藿香基地土壤养分含量的影响。结果表明不同施肥处理都促进广藿香产量、油量、品质及土壤养分含量的提高,但处理之间差异明显。产量及油量以75%有机肥+25%化肥处理最高,分别比对照平均增产31.58%和168.10%,60%有机肥+40%化肥处理次之,50%有机肥+50%化肥处理居中;广藿香株高、茎粗、分蘖数、叶面积指数等生长指标以及12种主要化学成分(β-广藿香烯、α-愈创木烯、刺蕊草烯、α-广藿香烯、δ-愈创木烯、苦橙油醇、β-榄香烯、异石竹烯、β-愈创木烯、反式-丁香烯、广藿香酮、广藿香醇)、水溶性和醇溶性浸出物等品质指标都以75%有机肥+25%化肥处理最高。广藿香基地土壤中有机质、碱解氮、速效磷和速效钾含量以100%有机肥、75%有机肥+25%化肥、60%有机肥+40%化肥、50%有机肥+50%化肥处理含量较高,其中100%有机肥处理最高,4个处理间差异不显著。结论得出,75%有机肥+25%化肥配施是适合广藿香施肥的方案。
Pogostemon cablin belongs to Labiatae,with reputation in the domestic and foreign markets.The Hainan Patchouli,in addition to medicine,due to high oil content,is also used to extract volatile oil for export. To test the effects of compound application of organic and chemical fertilizers on Patchouli plants,eight treatments of compound fertilizer mixed with organic fertilizer and chemical fertilizer were set to study their influences on Patchouli growth, yield, oil, quality and soil nutrient contents. The treatments were set as organic fertilizer of 100%( 100% OF),chemical fertilizer of 100%( 100% CF),75% OF + 25% CF,60% OF + 40% CF,50% OF + 50% CF,40% OF + 60% CF,25% OF + 75% CF and no fertilizer as control( CK). The results showed that different fertilization treatments promoted the improvement of Patchouli yield,oil,quality and soil nutrient contents,but an significant difference was presented between different treatments. The yield and oil were the highest in 75% OF + 25% CF treatment,which was 31. 58% and 168. 10% higher than those of CK, respectively, followed by60% OF + 30% CF and 50% OF + 50% CF treatments. The growth indexes of Patchouli,such as plantheight,stem diameter,number of tillers and leaf area index,and the qualities of the 12 kinds of main chemical components( β-Patchouliene,α-guaiene,exogenous squalene,α-patchoulene,δ-guaiene,nerolidol,β-elemene,caryophyllene,β-guaiene,trans-caryophyllene,pogostone,patchouli alcohol),water soluble and alcohol soluble extracts in 75% OF + 25% CF treatment were the highest. Organic matter,alkali solution nitrogen,available phosphorus and potassium contents in soil were higher in100% OF,75% OF + 25% CF,60% OF + 40% CF,and 50% OF + 50% CF treatments,and 100% OF treatment got the highest values, the difference between the four treatments was not significant.Therefore,the treatment of 75% OF + 25% CF could be suitable for Patchouli fertilization scheme.
