利用DTOPSIS法进行板栗疏雄效果的综合评价

目的]建立板栗疏雄效果的综合评价体系。方法]以檀桥板栗(C.mollissima‘tanqiao’)为试材,采用DTOPSIS法,综合分析11个与板栗产量及品质相关的主要参考性状(坐苞率、出实率、单苞重、坚果单粒重、产量、直链淀粉含量、支链淀粉含量、总淀粉含量、可溶性总糖含量、蛋白质含量和脂肪含量),验证板栗的疏雄效果。结果]通过建立评价矩阵、进行无量纲化处理、建立决策矩阵,计算各品种与理想解的相对接近度,得出雄花初开期疏除90%的雄花序得分最高,疏雄效果最好,且与实际观测值相吻合。结论]该评价方法属于多指标综合评价,比单纯使用产量或品质进行分析更为合理,可作为评定板栗疏雄效果的一种方法。

Comprehensive Evaluation of Thinning Staminate Inflorescences on Castanea mollissima Based on the Method of DTOPSIS

Objective] To establish a comprehensive evaluation system for the sparsely male effect of Castanea mollissima.Method] Taking C.mollissima ‘ tanqiao’ as test material,the multi-trait 11 main characters (seat cupule rate,fruit rate,single cupule weight,single kernel weight,yield,amylose content,amylopectin content,starch content,soluble sugar,protein and fat) were analyzed by the method of DTOPSIS.Result] The results showed that by first establishing the evaluation matrix,after dimensionless processing,establishing the decision matrix and calculating the relative proximity of the ideal solution,it can be intuitively concluded that the comprehensive scores of the treatments of male flowers open 90％ male inflorescence thinning period was in the top grade,the thinning effect was the best,and it accorded with the actual observation value.Conclusion] The evaluation method belongs to multiple index comprehensive evaluation,which is more reasonable than the simple use of yield or quality,and can be used as a method to evaluate the effect of chestnut thinning.
