Abstract
The investigation was conducted to find out amounts and ratios of N, P and K fertilizers applied on summer Chinese cabbage in 58 farmers' fields of highland area. The application levels of N, $P_2O_5$, $K_2O$, livestock manure and lime fertilizers were 444, 188, 390, 9,920 and $2,160kg\;ha^{-1}$, respectively, for summer Chinese cabbage. The ratios of basal dressing were 48% in N, 46.6% in $K_2O$. The frequencies of top dressing both N and K were 1.7 times. The kinds of compound fertilizers were in the order of 11-10-10+3+0.3 > 11-6-6+4+13+17 > 12-9-11+3+0.3 in basal application and 18-0-18+0.3 > 13-0-13+1+0.3 > 18-0-15+0.3 in top dressing. From the surveyed results, we could estimate that total 4,347 tons of N, $P_2O_5$, and $K_2O$ fertilizers were over used for summer Chinese cabbage by farmers in highland.
