云南大旱,影响木薯采收

    本网讯(通讯员 韦宾):入春以来,云南“三年连旱”的局面还在持续并不断加剧。据云南省气象局资料显示,去年12月至今年2月上旬,云南省平均降水量31.94mm,比去年同期偏少逾五成,比历年同期偏少12.1%,且降水时空分布不均,地域差异十分明显。加之连续三年遭受严重干旱影响,云南雨季有效径流减少。1月全省河道平均来水量较常年整体偏少31%,六大流域干流及其主要支流平均来水量与多年同期平均值比均有不同程度的减少。
    受干旱影响最严重的农业部门,面临着农作物减产、绝收、经济损失不断扩大的局面。据农业厅统计,截至目前, 全省农作物因旱受灾达到559.9万亩,成灾203.7万亩,绝收32.4万亩,造成种植业直接经济损失超过6亿元,其中:粮食作物受灾290.6万亩,成灾117.4万亩,绝收23.2万亩。受灾较重的作物有:小麦、豆类、大麦、蔬菜、油菜等。
    据调查,由于干旱的原因,木薯后期的生长受到了影响,产量和含粉率均比预估值有所降低,并且目前正当榨季时节,过硬的土地给采收作业带来了极大的不便和困难,使之更直接影响到淀粉工厂的原料供给。
    另据了解,云南旱情目前呈迅速蔓延(向滇南和滇西地区扩散)和日益加重的发展态势,形势严峻。
