Abstract
The field trial was carried out to study the effect of NPK combination on forage yield and nutrient accumulation in sudangrass and ryegrass rotation.The results indicated that the total fresh matter yield of NPK combination were the highest(162.7t/hm2)among all treatments.In which,the fresh matter yield of sudangrass was 102.3 t/hm2,and it was 352.7%,356.7%,28.2% and 13.9% more than that of CK,PK,NK and NP treatments respectively.The fresh matter yield of ryegrass was 60.4 t/hm2,and it was 344.1%,255.3%,24.8% and 25.3% more than that of CK,PK,NK and NP treatments respectively.In NPK treatment,the average daily accumulation rate of forage dry matter was 65.2 kg/hm2,it was 215.0%,197.5%,22.0% and 9.6% more than that of CK,PK,NK and NP treatments in whole growth period,and they were 104.5 kg/hm2 and 36.9 kg/hm2 for sudangrass and ryegrass respectively.NPK combination obviously improved the nutrient accumulation in forage,and the accumulation amounts of N,P2O5 and K2O were 500 kg/hm2,210 kg/hm2 and 1196 kg/hm2,and the average daily accumulation rates in the whole period for N,P2O5 and K2O was 1.37 kg/hm2,0.58 kg/hm2 and 3.29 kg/hm2 respectively,in which,they were 2.12 kg/hm2,0.79 kg/hm2 and 4.16 kg/hm2 for sudangrass and 0.84 kg/hm2,0.43 kg/hm2 and 2.66 kg/hm2 respectively for ryegrass.
