肥料效应田间试验是获得不同栽培条件(设施、露地)最佳施肥数量、施肥品种、施肥比例、施肥时期、施肥方法的根本途径,也是筛选、验证土壤养分测试方法、建立施肥指标体系的基本环节。2015年建水县进行了大白菜“2+x”肥料效应田间试验,结果显示:该地区土壤类型随着氮、磷、钾肥料的合理配比,产量呈上升的趋势。大白菜最佳经济产量配方以N 10.8︰P_2O_57.2︰K_2O10.8为宜,比值为1︰0.67︰1。白菜每667m~2产量可达7210.36kg左右,可作为该区域今后栽种大白菜时,施肥分区、肥料配方和节本增效提供参考依据。
Fertilizer effect The field experiment is the fundamental way to obtain the optimal fertilization quantity, fertilization variety, fertilization proportion, fertilization period and fertilization method under different cultivation conditions (facilities and open fields), and is also the basic way of screening and verifying the soil nutrient testing method and establishing fertilization index system . In 2015, a field experiment was conducted on the fertilizer effect of Chinese cabbage “2 + x” in Jianshui County. The results showed that with the reasonable proportion of nitrogen, phosphorus and potassium fertilizers, the yield of soil increased in this area. The best economic yield of Chinese cabbage is N 10.8︰P_2O_57.2︰K_2O10.8, the ratio is 1︰0.67︰1. Cabbage per 667m ~ 2 yield up to 7210.36kg, can be used as the region planted cabbage in the future, fertilization zoning, fertilizer formula and cost-effective basis to provide a reference.
