基于模糊综合评价法的压砂地欧李品种筛选

Screening of Cerasus humilis in Gravel-mulched Field Based on Fuzzy Comprehensive Evaluation Method

以10种不同品种欧李为试材,在田间试验条件下,研究了其生长指标、叶绿素相对含量、产量以及果实品质;同时引入模糊综合评价法,构建产量、品质和生物学性状方面共10个因子的欧李品种综合效益评价体系,采用层次分析法(AHP)确定各评价因子的权重,结合隶属度函数及5个等级的评价矩阵,通过模糊综合评价数学模型计算得出不同品种压砂地欧李综合效益评价值,为压砂地欧李产业的发展提供参考依据。结果表明:水肥和栽培相同条件下,‘5号’的667m^2产量最高,‘4号’果实钙含量及其叶片叶绿素相对含量最高。10个品种欧李模糊综合效益值排序为‘6号’>‘07-14’>‘5号’>‘03-25’>‘4号’>‘7号’>‘S-D’>‘23-04’>‘03-35’>‘9号’。根据单因素分析结果,‘5号’和‘4号’具有较好的适应性。欧李坐果主要依靠异花授粉,根据模糊综合效益值排序,可选取‘6号’‘07-14’‘5号’欧李在压砂地种植。

Under the field experiment condition,taking 10 different varieties(lines)of three-years Cerasus humilis as the test materials,the plant height,stem diameter,chlorophyll relative content,yield and fruit quality of them were researched and analyzed.And the fuzzy comprehensive evaluation method was introduced at the same time.The comprehensive benefits evaluation system of the different varieties of Cerasus humilis in gravel-mulched field was build with 10 indexes which were included in yield,quality and biological characteristics.Then,the Analytic Hierarchy Process(AHP)to definite the weight of each evaluation index was adopted,and the membership function as well as the evaluation matrix of five levels was combined.Finally,the comprehensive benefits evaluation values of the different varieties of Cerasus humilis in gravel-mulched field was calculated by fuzzy comprehensive evaluation mathematics model,in order to provide theoretical basis and technical support to the development of the Cerasus humilis as well as gravel-mulched field industry.The results showed that the ‘No.5’had the best yield in 10 varieties(lines),‘No.4’had the highest calcium content of its fruit and the chlorophyll relative content of its blade in the same condition.Ranking the comprehensive benefits evaluation values of the different varieties of Cerasus humilis,‘No.6’was the best,following the ‘07-14’‘No.5’‘03-25 ’‘No.4’‘No.7’‘S-D’,then was the‘23-04’‘03-35’,the worst was‘No.9’.According to the analysis results of single factor,the‘No.5’and‘No.4’had better adaptation in gravel-mulched field.The Cerasus humilis bear fruits depened on alienation pollination,the‘No.6’‘07-14’and ‘No.5’were selected to plant in gravel-mulched field depend on the rank of fuzzy comprehensive benefits.
