摘要：

为确定辣椒最佳施肥方式，采用L9(34)正交设计，分别选取氮磷钾施肥总量、氮磷钾配比、有机肥用量、各时期施肥分配量4个因素，各3个水平，测定辣椒在关键生育期的生长性状各指标和经济性状；在收获期进行实验室考种，考察产量并核算经济效益。结果表明，施肥方式的最优组合为：氮磷钾施肥总量为900 kg/hm2，其中氮肥300 kg/hm2、磷肥225 kg/hm2、钾肥375 kg/hm2，需要有机肥15000 kg/hm2，该组合下，辣椒的产量可达35335.60 kg/hm2，产值可达49906.96~61214.35元/hm2。

Abstract:

In order to determine the optimum fertilizer application style. The experiment was designed according to orthogonal test with L9(34). The three selected factor were total fertilization amount of nitrogen phosphorus and potassium, nitrogen phosphorus and potassium combination, application of organic manure, application rate in every period. According to all indexes determination of growth traits and economic characters, study of yield in all treatments and accounting economic benefit. The results showed that the optimum fertilizer application style combination total fertilization amount of nitrogen phosphorus and potassium was 900 kg/hm2, which 300 kg/hm2 nitrogen, 225 kg/hm2 phosphorus, 375 kg/hm2 potassium, application of organic manure was 15000 kg/hm2, under the combination, the yield reached 35335.60 kg/hm2, the output value reached 49906.96-61214.35 yuan/hm2.
