Abstract
In the experiment,not completely randomized design was used in the field.Phosphorus,potassium and sulfur fertilizer were applied on alfalfa(Medicago sativa L.)planted in flower pots.Phosphate fertilizer used SSP,located three levels:40,55,70 kg/hm2,which was showed by P1,P2,P3,respectively.Potash fertilizer used of potassium chloride,set up three levels:220,280,340 kg/hm2,which was showed by K1,K2,K3,respectively;sulfur fertilizer used of ammonium sulfate,established three levels:30,50,70 kg/hm2,which was showed by S1,S2,S3,respectively(ammonium sulfate in excess of urea nitrogen to the missing).Effect of different combined application levels of three fertilizers on production of Alfalfa(One Zhongmu).The results showed that alfalfa planted by seeds,hay yield,plant height,leaf area,chlorophyll content,branches numbers improved significantly(p0.05)within a certain range by applying phosphate fertilizer,potash fertilizer,sulfur fertilizer in sowing year,growth rate increased and the proportion of stems and leaves reduced.In the current soil ferlilizer,P,K,S were applied at the same time when the levels of P,K,S were P2,K2,S2,the highest yield,the fastest growth rate,the most branches numbers,the largest leaf area and the most chlorophyll content were obtained.The proportion of stems and leaves was the largest when the lavels of P,K,S were P1,K1,S1.Rootnodule numbers were the most and fresh weight were the largest when the levels of P,K,S were P3,K2,S2.
