以酿酒葡萄“马瑟兰”(Vitis vinifera L.‘Marselan’)为试验材料,设置4个施肥水平(N-P2O5 K2O),即80-60-105 kg/hm2 (F1)、160-120-210 kg/hm2(F2)、240180-315 kg/hm2(F3)和320240-420 kg/hm2(F4),以不施肥为对照(CK),利用固相萃取—气相色谱—质谱联用技术,研究不同施肥量对其果实香气成分的影响.结果 表明:不同施肥量对葡萄果实香气成分组成和含量影响不同.与CK处理比较,施肥处理提高了葡萄果实中高级醇类、脂肪酸类、苯衍生物和烃类物质的含量;增加了高级醇类和脂肪酸类物质种类,降低了醛类、酯类和苯衍生物物质种类.其中F2处理香气成分含量最高、种类数居中,同时,有利于提高果实中高级醇类、醛类、烃类以及苯类衍生物的含量.

Taking Calligonum mongolicum,Hedysarum scoparium,Caragana korshinskii as test materials,the application effect of peat and its preparations in desert control launched in the southwest edge of Tengger desert other commonly used sand fixation afforestation tree species were studied.The results showed that survival rate of afforestation of various selected tree species by peat application Calligonum mongolicumHedysarum scopariumCaragana korshinskiiTamarix ramosissima,among which the survival rate of Calligonum mongolicum was treatment groupcontrol group;survival rate of Caragana korshinskii was treatment groupcontrol group,survival rate of Hedysarum scoparium was treatment groupcontrol group,survival rate of Tamarix ramosissima was treatment groupcontrol group,while growth potential of afforestation of various selected tree species by peat application Caragana korshinskiiHedysarum scopariumCalligonum mongolicum,growth potential of Hedysarum scoparium was control grouptreatment group;growth potential of Caragana korshinskii was control grouptreatment group;growth potential of Calligonum mongolicum was control grouptreatment group.It indicated that when selecting tree species for afforestation,Calligonum mongolicum(with higher survival rate and relatively stable growth potential)should come first,followed by Hedysarum scoparium and Caragana korshinskii,minimizing the use of Tamarix ramosissima,and finally peat and its preparations should be added in Calligonum mongolicum and Hedysarum scoparium.
