摘要
应用灰色关联分析法对葡萄营养剂K施用方案进行了综合评价.结果表明:A1(基施营养剂K、始花期叶面喷施)的灰色综合评判值0.846,为一级方案;A4(始花期、花后一周、花后两周叶面喷施营养剂K)的灰色综合评判值0.701,为二级方案;A2(始花期叶面喷施营养剂K)、A3(花后一周、花后两周叶面喷施营养剂K)的灰色综合评判值介于0.500~0.600之间,为三级方案;A0(不施营养剂K)的灰色综合评判值<0.400,为四级方案.
The results of comprehensive evaluation of application projects of grape nutrition enhancer by using grey system theory showed that evaluated score of A1 treatment (initial dressing and foliar spraying at early flower stage) was 0. 876, which was the best strategy. Evaluated score of A4 treatment (foliar spraying at early flower stag and at one and two weeks after flowering) score was 0.701, which was second strategy. Evaluated score of A2(foliar spraying at early flower stage) and A3(foliar spraying at one and two weeks after flowering)were between 0.50 and 0.60, which was the third strategy;A0 (Control) score was under 0.40, which was fourth strategy.
