摘要
采用随机区组试验设计,在河北省沧州南皮县试验站对生长第三年的紫花苜蓿施用配制的6种苜蓿专用复合肥,研究其对牧草干物质产量和经济效益的影响.结果表明,专用肥1、2、5、6号与习惯施肥和不施肥对照相比,既能增产又能增收,其中,6号专用肥增产显著,经济效益最高,其增产和效益主要来源于前两茬;专用肥3、4号增产不增收.
The experiment was carried out at an experimental station of NanPi County,Hebei Province from March to November in 2002 to study the effects of six species of special fertilizers on the forage yield and profits of Alfalfa by using established three-year-old stand of 'Vector' alfalfa(Medicago sativa L),and random block was desished,The result shows that the dry matter and the economic profits of alfalfa increase more by using special fertilizers No 1,2,5,6 than that of tradition fertilizer application and control.Furthermore special fertilizer No 6 is the best,the increase in yield and profits comes mainly from the first two cutting.
