摘要
为明确云南省瑞丽雪茄烟区土壤合理施肥方案,采用"3414"肥料试验设计,通过熵权法和回归分析,计算了各处理对应的烟株农艺性状综合得分,探究了N、P、K对雪茄烟株长势和烟叶产量的影响,筛选出最佳施肥方案.结果表明:(1)株高对雪茄烟株农艺性状的得分所占权重最大,处理6(N2P2K2)对应的得分最高.(2)在一定范围内增加N、P、K的施用量,对雪茄烟的产量有积极作用,然而随着施肥量的增加产量又有所下降.(3)构建了N、P、K施用量对雪茄烟产量的二元二次和三元二次回归模型,最佳施肥方案为N施用量在118.7～126.9 kg/hm2之间,P2O5施用量在75.7～81.4 kg/hm2之间,K2O施用量在342.1～366.5 kg/hm2之间,目标产量在1816.3～1812.5 kg/hm2之间.
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.
