| Abstract: | This experiment was conducted with Xinong 8 was an indicator variety to study the effect of balanced fertilization on watermelon growth in semi-arid and partial moist district of eastern Gansu.The results showed that the yield and economic benefit of watermelon achieve the maximum when the application amounts of N,P2O5 and K2O reached 180 kg/hm^2,120 kg/hm^2 and 90 kg/hm^2,respectively,and the economic efficiency were 30 148.1 kg/hm^2,41 277.0 yuan/hm^2,respectively,on this basis,increased the potassium fertilizer was not economy. |
