摘要：

采用二次回归饱和D-最优试验设计方法，研究了固态N、P和K肥施用量对日光温室有机生态型无土栽培长季节番茄产量的影响，建立了N、P和K肥施用量与番茄产量形成之间的方程模型。结果表明：N、P及K对长季节栽培番茄的早期、中期和后期产量都有明显的影响，番茄前期的最佳施肥量（单位：g／株·次。以下同）为N=0.72，P2O5=0．32，K2O=1．04；番茄生长中期N、K肥的需求量增加，番茄中期的最佳施肥量为N=0．85．P2O5=0．22，K2O=1．40;番茄生长后期，N和K肥需求量都稍有所下降，最佳施肥量为N=0．78，P2O3=0．25，K2O=1．27。

Abstract:

Application of saturated D-optimal design, total of 10 treatments, experiment on effect of nutrient N, P and K on yield of long term tomato cultivation was conducted by directly supplying solid N, P and K fertilizer （mixture of organic and inorganic fertilizers） in eco-organic type soilless culture system, related models between fertilization amount and yield at different growth stage were established. The results indicated that N, P and K nutrient had significant effects on tomato early, middle and late yield. The optimum fertilization amount of N, P2O5 and K2O were 0.72 （g/plant/time, the same as the following）, 0.32 and 1.04 respectively during early growing stage of tomato. The demand for N and K increased during middle growth period, the optimum fertilization amount of N, P2O5 and K2O were 0.85, 0.22 and 1.40 respectively. And then demand for N and K slightly decreased during late growth period, the optimum fertilization amount of N, P2O5 and K2O were 0.78, 0.25 and 1.27 respectively.
