基于3414试验设计的云南雪茄烟叶生产施肥技术研究
Study on Fertilization Technology of Yunnan Cigar Production Based on"3414"Experiment Design
摘要
Abstract
In order to clarify the rational soil fertilization of Yunnan Ruili tobacco-growing area,the"3414"fertilizer experiments were designed.According to the entropy weight method and regression analysis,the scores of agronomic traits of cigar corresponding to each treatment were calculated.The effects of N,P and K on cigar yield and the optimum fertilization amount were investigated.The results showed that:(1)Plant height contributes the most to the total score of agronomic traits.Treatment 6(N2P2K2)has the highest score.(2)After an increase of the yield within a certain range,it decreased when the amount of fertilizer kept growing.(3)Binary quadratic and ternary quadratic regression models were established.The optimum amount of N,P2O5 and K2O was at the range of 118.7～126.9 kg/hm2,75.7～81.4 kg/hm2 and 342.1～366.5 kg/hm2,respectively.The target yield was between 1816.3 and 1812.5 kg/hm2.关键词
