摘    要:[目的]为了研究贵州省低热地区N、P、K施用量与产量的相关关系。[方法]采用"3414"二次回归设计,以N、P、K为供试因子,番茄产量为目标函数,对贵州省低热地区早熟番茄施肥数学模型进行研究。[结果]根据建立的数学模型获得优化施肥技术方案:N、P、K最佳施用量分别为104.55、112.95、502.95 kg/hm2,产量可达115 719.00 kg/hm2。[结论]该研究为优化N、P、K肥施用量,制定番茄专家系统的施肥决策提供了依据。

关 键 词:早熟番茄  氮(N)  磷(P)  钾(K)  施肥模型

Abstract:[Objective] The aim of this paper was to study the relationship between the yield and application amount of N,P and K in lower altitude areas of Guizhou Province.[Method] Using the quadratic regression design of 3414,mathematical model of fertilization for earlier tomato was studied in lower altitude areas in Guizhou Province by taking the N,P and K as factors and the yield of tomato as objective function.[Result] According to the mathematical model,with the optimal proportion of fertilizer N,P and K of 104.55 kg/hm2,112.95 kg/hm2 and 502.95 kg/hm2,respectively,the yield could reach 115 719.00 kg/hm2.[Conclusion] References were offered in this paper for the application of N,P and K as well as making fertilization decision of tomato expert system.
Keywords:Earlier tomato  N  P  K  Fertilization model
