摘　　要：对越西秋荞麦分期播种田间试验资料进行统计分析,研究秋荞麦生长发育规律、产量与气候的关系、气候资源,并总结了秋荞麦的主要气象灾害和防御对策。结果表明,越西秋荞麦一般在7月下旬—8月上旬播种,10月中旬—下旬成熟收获,生育期较短(70~80 d)。该区秋荞麦气候资源优势:热量丰富,无霜期长,无高温热害,温度适宜秋荞麦生长;结实期昼夜温差大,有利营养物质积累和产量、品质提高;日照充足,提高了积温、太阳辐射的有效性;降水丰沛,夜雨多,空气湿润度适宜,有利灌浆结实。The growth and development of autumn buckwheat, the relationship between yield and climate, climate resources and the main me- teorological disaster and defense measures of autumn buckwheat were studied by statistical analysis of field experiment data of phased planting autumn buckwheat in Yuexi County. The results showed that autumn buckwheat was generally sown in late July-early August, mature and har- vest in mid-October - late October, and had shorter growth period （70 - 80 days）. The advantages of climate resources of autumn backwheat in this area ： Rich in heat, long frost-free period, no high temperature damage, the temperature suitable for autumn buckwheat growth. The tem- perature difference between day and night was strong in filling stage, which was beneficial to nutrient accumulation and yield, and the quality was improved. Sunshine sufficient to improve the accumulated temperature and the effectiveness of solar radiation. Abundant rainfall, more rain at night and air moistness appropriate were favorable for filling.
