洛南地处秦岭山麓,无霜期短,光照不足,造成了夏播作物(主要是晚玉米)不能顺利生长。历年来,晚玉米亩产都在100-200斤之间,有的则不能成熟,成了“包袱”、“拉腿田”。群众说:“秋赶夏、夏赶秋、两料不如一料收”。这个问题不解决,农业生产就缺乏主动权,要上纲要就困难。 Luonan is located in Qinling foothills, frost-free period is short, lack of light, resulting in summer sowing crops (mainly late corn) can not grow smoothly. Over the years, the output of late-night corn is between 100 and 200 kg, while others can not mature and become the “burden” and the “leg-pulling.” The masses said: “autumn rush summer, summer rush autumn, two expected better than a harvest.” If this problem is not solved, there will be a lack of initiative in agricultural production and difficulty in going to the outline.
