氮磷钾配施对温室秋冬茬番茄产量的影响

Effect of Different N,P,K Ratios on Yield of Autumn-Winter Tomato in Greenhouse

采用"3414"回归设计,研究了氮磷钾配施对温室秋冬茬番茄产量的影响。结果表明:温室番茄最高产量施肥量是氮肥(N)259.3 kg/hm2,磷肥(P2O5)196.6 kg/hm2,钾肥(K2O)190.5kg/hm2,最高产量是76 029 kg/hm2;最佳产量施肥量是氮肥(N)249.3 kg/hm2,磷肥(P2O5)186.8kg/hm2,钾肥(K2O)183.4 kg/hm2,最佳产量是75 987 kg/hm2。

Utilizing ＂3414＂ regression design, the effect of different N, P, K ratios on yield of autumn-winter season tomato in greenhouse, the results showed that, The quantity of applying fertilizer of the maximum yield of tomato in greenhouse was nitrogen fertilizer （N）：259.3 kg· hm^-2 ,phosphate fertilizer （P2O5）：196.6 kg · hm^-2 ,potassium fertilizer （K20） ： 190. 5 kg · hm^-2, the maximum yield of tomato was 76 029 kg· hm^-2 ; The quantity of applying fertilizer of the best yield is nitrogen fertilizer （N）：249.3 kg · hm^-2 , phosphate fertilizer （P20s ）：186. 8 kg· hm^-2 , potassium fertilizer （K2O） ： 183.4 kg · hm^-2 , the best yield of tomato is 75 987 kg · hm^-2 .
