| 摘 要： | 采用311-A拟饱和最优回归设计，对胡萝h施用氮、磷、钾肥料进行试验。试验结果运用计算机DPS数据处理系统进行统计分析，模拟出胡萝h氮、磷、钾肥料施用量码值与产量及利润的回归方程，应用边际分析方法，获得小白菜最高产量施肥量为氮肥177．26Kg／hm^2纯N，N：P2O5：K2O=1：0．51：1．61；最佳利润施肥量为氮肥174．43Kg／hm^2纯N，N：P2O5：K2O=1：0．50：1．66。获得胡萝卜高产时使用的施肥量及最佳利润施肥量。

| Abstract: | To develop the technology of balanced fertilizer in carrot vegetable crop,311-A regression designment was employed to test the balanced application rate of N,P,K in carrot vegetable crop by using mathematical statistic analysis of computer Data Processing System.The regression equation in the relationship between the fertilizer and yield as well as its profit have been simulated.The marginal analysis indicated that the most suitable fetilizer for the highest yield of carrot is 177.26 N kg/hm2,and the ratio of N :P2O5: K2O is 1:0.61:1.61,the most suitable fertilizer for the highest profit of carrot is 174.43 N kg/hm2,and the ratio of N:P2O5:K2O is 1:0.50:1.66. |
