| 摘 要： | 我县测土配方施肥增产增收效果显著,据3 a来测土配方施肥试验示范结果,得出我县川水、浅山、半浅半脑和脑山地区的最佳施肥量,并得出我县粮食作物测土配方施肥比农民常规施肥增产450㎏.hm-2,增产率接近10%以上。测土配方施肥比常规施肥的施氮量减少27㎏.hm-2,氮肥利用率提高10个百分点以上;施磷量减少60㎏.hm-2左右,磷肥利用率提高7~10个百分点;施钾量有所增加,其利用率提高7个百分点。

| Abstract: | Soil testing and fertilizer recommendation had made remarkable effect , the output and benefit were increased significantly, the optimum amount of fertilization were got of different altitude by test of three years,the yields of soil testing and fertilizer recommendation were higher 450 kg·ha^-1 than that of conventional fertilizer application,increasing rate was nearly 10%, nitrogen rate of soil testing and fertilizer recom mendation were reduced 27 kg·ha^-1 compared with conventional fertilizer application, utilization rate of N, P,K fertilizer were raised by 10% ,10% and 7% respectively. |
