（一）存在问题
有机肥和钾肥施用量不足。
（二）施肥原则
1、依据土壤肥力水平优化氮磷化肥用量；
2、增施有机肥，提倡有机无机配合施用；
3、依据土壤钾素状况，适当增施钾肥；
4、肥料施用应与高产优质栽培技术相结合。
（三）施肥建议
1、亩产3000公斤以上条件下：氮肥(N)11-13公斤/亩，磷肥(P2O5)5-6公斤/亩，钾肥(K2O)14-17公斤/亩；
2、亩产2000-3000公斤条件下：氮肥(N)9-11公斤/亩，磷肥(P2O5)4-5公斤/亩，钾肥(K2O)12-14公斤/亩；
3、亩产1500-2000公斤条件下：氮肥(N)7-9公斤/亩，磷肥(P2O5)3-4公斤/亩，钾肥(K2O)9-12公斤/亩；
4、亩产1500公斤/亩以下条件下：氮肥(N)6-7公斤/亩，磷肥(P2O5)3-4公斤/亩，钾肥(K2O)7-8公斤/亩。
肥料运筹：氮肥70%作基肥，30%作苗期追肥；磷钾肥全部作基肥。亩施2-3方有机肥作基肥。对于硼或锌缺乏的土壤，可基施硼砂1公斤/亩或硫酸锌1-2公斤/亩。
