| 摘 要： | 评价烟草栽培措施的优劣十分复杂,各指标参数难以统一。加权灰色局势决策能将多个性状指标归纳为统一的量化综合指标,较单一性状的分析更为合理。运用加权灰色局势决策方法对pH值对烟草的影响进行综合评价,得出pH值在6～8的范围内有利于烟叶的生长,结果与目前实际生产实际符合,说明该方法客观、合理,可以在评价栽培措施时应用。

| Abstract: | It was very complex that appraise superior and poor of cultivating practices of tobacco since it was very difficult to unify various parameters.Weighted grey situation decision can integrate the many characteristics into the unified quantitative indices,and the single trait analysis was more reasonable.Comprehensive evaluation of the impact of pH value to tobacco by method of weighted grey situation decision,the result showed that pH value ranged from six to eight was beneficial to growth of tobacco and acc... |
