氮磷钾配比对云烟100生长发育及产质量的影响
Effects of N-P-K Ratio on Growth, Yield and Quality of Flue-cured Tobacco Variety Yunyan 100
摘要
Abstract
The effects of N-P-K ratio on the yield and production value of flue -cured tobacco variety Yunyan 100, as well as the benefit of applying N , P, K fertilizer were studied through field test by using D -saturation optimum regression design .The results showed that the optimum N , P2 O5 , and K2 O application level for obtaining the highest yield ( 3080.14 kg/hm2 ) was-0.2858, -0.0710, and 0.0906 respectively.The optimum N, P2 O5 , and K2 O application level for obtaining the maximum pro-duction value (39513.59 yuan/hm2) was -0.9552, -0.0149, and 0.3683 respectively.The optimum N, P2O5, and K2O appli-cation level for obtaining the highest fertilization benefit (36710.92 yuan/hm2) was -1, -0.0248, and 0.2840 respectively.Un-der the highest fertilization benefit , the yield of flue-cured tobacco was 2956.48 kg/hm2 , and the production value was 38174.43 yuan/hm2 .By comprehensive analysis , it was concluded that the optimum application rate of N , P2 O5 , and K2 O was 64.28, 144.3~148.95, and 235.2~266.4 kg/hm2, respectively, namely the optimal N-P2O5 -K2O ratio was 1∶(2.2~2.3)∶(3.6~4.1).关键词
