海南澄迈地区甘薯氮磷钾“3414”肥效研究
|
摘要
[目的]确定甘薯适宜施肥量。[方法]采用"3414"施肥方案,研究不同氮、磷、钾配比对甘薯产量及经济效益的影响。[结果]各施肥处理对甘薯的产量和经济效益的影响表现依次为施肥>不施肥,氮磷钾肥增产的主次顺序为N>K>P;施肥量与产量间的三元二次方程拟合结果典型,能够较好地反映施肥量与产量、经济效益间的关系。[结论]综合考虑,试验条件下获得最高产量施肥方案为最高产量27 871.5 kg/hm~2,N、P_2O_5、K_2O施用量分别为156.90、53.40、243.75 kg/hm~2;最佳经济效益的N、P_2O_5、K_2O施用量分别为156.30、53.10、241.50 kg/hm~2,最佳经济效益为191 356.5元/hm~2。
[Objective]The aim was to determine the optimal fertilization program for sweet potato.[Method]Based on the "3414"fertilization design,the effects of different amounts of nitrogen,phosphorus and potassium fertilizers on the yield and economic benefits of the plant were evaluated.[Result]Based on the yields and economic benefits,the fertilization treatments was ranked as follows:fertilized>non-fertilized,and N>K>P. The data for plant yield and economic benefits under the different fertilizer treatments fitted well with ternary quadratic. Therefore, the equations represented the relationships between fertilizer quantity and yield/economic benefits. [Conclusion]The maximum yield of sweet potato was 27 871.5 kg/hm~2 when applying dosages of N,P_2 O_5 and K_2 O were 156.90,53.40 and243.75 kg/hm~2 respectively,and the best economic benefit was 191 356.5 RMB yuan/hm2 when applying dosages of N,P_2 O_5 and K_2 O were 156.30,53.10 and 241.50 kg/hm~2 respectively.
