摘要
从与烟草生长发育密切相关的温度、日照、降雨量等气候因子入手,采用统计分析方法,分析2014年铜仁市异常气候条件下光照、温度及降雨量对铜仁市烤烟生长发育和产量的影响.结果表明,苗期日照时数显著偏少成苗素质降低；移栽至还苗期寡照对烤烟移栽有利但不利于还苗；旺长期强降雨等强对流天气多发、光照不足,灾情较严重,不利于烟株早生快发,对烤烟产质造成重大不利影响；成熟期多雨寡照、高温高湿不利于于物质累积,病害严重,影响烟叶品质.特别是4月下旬、5月下旬、6月上旬、7月中旬、8月中旬全市出现持续性暴雨、大暴雨、局部特大暴雨,给烤烟生产造成了严重损失.总体来说,2014年铜仁市烤烟生产的农业气候条件较差,烟叶产量和质量均下降.
Abstract
Starting from temperature,sunshine , precipitation and other climatic factors , which are closely related the growth and development of tobacco,effects of sunshine,temperature and precipitation on growth and yield of flue-cured tobacco in Tongren City under abnormal climatic conditions in 2014 were analyzed. The results showed that in seedling stage , sunshine hours were markedly Iess and seedling quality decreased; in transplanting to return to seedling stage, sunlight shortage was good for flue-cured tobacco transplanting but bad for seedling; in vigorous period,strong convective weather multiple happened,insufficient illumination. serious disaster,these factors were not conducive to early growth and quick tiller and quality of tobacco production; in mature period ,rainy and sunlight shortage , high temperature and high humidity were bad for dry matter accumulation, disease severity affected the quality of tobacco leaves. Especially in late April, late May , early June , mid-July and mid-August,torrential rain,heavy rain,local heavy rainfall caused serious damage to flue-cured tobacco production. In general,agricultural climate conditions of flue-cured tobacco production were poorer,yield and quality of tobacco leaves were falling in Tongren in 2014.
