| 摘 要： | 采用通用旋转设计方法，以氮、磷、钾肥为供试因子，西瓜产量为目标函数，对西瓜高产数学模型进行了研究。根据模型得出最佳产量施肥量为：Ｎ２１０ｋｇ／ｈｍ２，Ｐ２Ｏ５８０ｋｇ／ｈｍ２，Ｋ２Ｏ１７５ｋｇ／ｈｍ２。此时产量为４７１７５．９ｋｇ／ｈｍ２，利润为２６９１０．５元／ｈｍ２。并对氮磷钾单因素效应及交互作用作了具体剖析

| Abstract: | With the design of the current rotation regression combination,the high yield mathema tical model on watermelon was studied,in which N,P and K were supplying factors,watermelon yield was objective funcation. According to the objective funcation,the most suitable amounts of fertilization for yield were as follows:N 210kg/ha,P 2O 5 80kg/ha,K 2O 175kg/ha,under this circumstance,the yield was 47175.9kg/ha,the profit was 26 910.5 yuan/ha. In addition,the single factor effects of N,P,K and their interaction was analysed specificly. |
