Abstract
Fertility of Rice ecosystems under no fertilization treatment decreased,the average rice biomass and the average grain yield of different treatments reflected that not only nitrogen fertilizer but also phosphate fertilizer was limited factors on them in Meadow Brown soil,and conjunction of both nitrogen and phosphate fertilizer would display land capacity and gain higher yields.Soil total N of all treatments decreased compared to pretest and the total P content of most treatments increased.The average rice biomass and the average grain yield of N180P100K70 fertilization was the highest,and P content in seeds was the second and this illustrated the treatment was best in all fertilization treatments.Soil urease activity of N180P70K70,N240P70K770 and N180P100K70 fertilization was equal to CK but other three fertilization treatments were inhibited.Soil nitrate reductase activity increased excepted two treatments.Proper quantities of nitrogen and phosphate fertilizer conjunctional application would increase grain yield and enhance enzymes activities.
