摘要: 为了探明日光温室嫁接辣椒的氮(N)、钾(K2O)适宜施用量及其与自根辣椒的差异,采用二次饱和D-最优设计,研究N、K2O用量对嫁接和自根辣椒产量的影响,并建立了以N、K2O用量为变量因子,以嫁接和自根辣椒产量为目标函数的二元二次数学模型。对模型解析的结果表明,N、K2O用量对辣椒产量影响显著,二因子存在着交互效应,但以K2O对辣椒的产量影响较大。通过计算机模拟运算,得出本试验条件下嫁接辣椒产量达到49 500 kg/hm2以上的优化施肥方案为N 326.1~752.9 kg/hm2,K2O 630.8~1 116.0 kg/hm2;自根辣椒产量达到48 000 kg/hm2以上的优化施肥方案为N 411.5~606.9 kg/hm2,K2O 868.4~1 168.4 kg/hm2,嫁接辣椒适宜的氮钾配比为嫁接1:1.96,自根辣椒1:1.85。

Abstract: The purpose of this paper is to elucidate the optimum amounts of nitrogen and potassium in grafted peppers which cultivated in solar-greenhouse,and the difference of them between grafted and the own-root plants. The effects of nitrogen and potassium on the yield of grafted and own-root peppers were investigated with the design of two factors and double saturated D-optimal regression. A mathematical model for the optimization was established using nitrogen and potassium amounts as the independent variables,and the yield of grafted and own-root plants as objective function. The results showed that nitrogen and potassium significantly influenced the yield of grafted and own-root peppers,and there were interactive effect between nitrogen and potassium. However,potassium had higher effect on the yield of pepper. Through simulated computation,the schemes of optimized fertilization of grafted and own-root peppers were finally obtained. The yield of grafted pepper could reach to 49 500 kg/ha or more when the fertilizer rates were N 326.1-752.9 kg/ha,K2O 630.8-1 116.0 kg/ha;the yield of own-root pepper could reach to 48 000 kg/ha when the fertilizer rates were N 411.5-606.9 kg/ha and K2O 868.4-1 168.4 kg/ha. The suitable ratio of N:K2O of grafted pepper was 1:1.96,and that of own-root pepper was 1:1.85.
