小麦是云南省的第三大粮食作物，常年种植面积约７０万ｈａ，其中旱地小麦面积约５０万 ｈａ，占全省小麦种植面积的 ７０％左右，由于无灌水条件，耕作粗放，产量在很大程度上受当年冬春气候条件所制约，一般每公顷产量１５００～２２５０ｋｇ。本研究运用灰色关联分析方法，
Wheat is the third largest grain crop in Yunnan Province with annual planting area of about 700,000 ha. The area of dryland wheat is about 500,000 ha, accounting for about 70% of the wheat acreage in the whole province. Due to the non-irrigation conditions, the cultivation is extensive and the output is very high To a large extent by the winter and spring climatic conditions, the general output per hectare 1500 ~ 2250kg. In this study, using gray correlation analysis method,
