Abstract
In order to achieve high efficient application of fertilizer, normal method and local method were compared in this experiment. The result showed that the highest yield was 10 422.9 kg·hm^-2with treatment of N2 P3K2 ,the following was 10 366.9 kg·hm^-2 with treatment Of N2P2K2. The ratio of output to input with application of N2 P3 K2 was 14.9 ∶ 1, while N2 P2 K2 was 16.8 ： 1. Therefore, the economic benefit of N2P2 K2 was rational; The optimum amount of Nitrogen was 198.7 kg· hm^-2, phosphate was 136.0 kg· hm^-2 and potassium was 152.9 kg·hm^-2.关键词
