我省玉米种植面积广阔,由于纬度高无霜期短,又由于一些地区跨区种植,收获季节玉米籽粒含水率大多数>35%。造成玉米籽粒脱水难,贮藏难、销售更能。每年用于烘干、晾晒等费用达20亿元之多,大量“水苞米”品质差卖不上好价,降低了种植地玉米籽粒水分的高产技术研究,通过品种选择,栽培技术措施多方面试验及配套技术示范,取得了一些成果。 Maize planting area in our province is broad, due to the high latitude and short frost-free period, but also due to cross-regional planting in some areas, harvest season, the majority of corn grain moisture content> 35%. Resulting in dehydration of corn grains difficult, difficult storage, sales more. Each year for drying, drying and other costs up to 2000000000 yuan, a large number of “water rice ” poor quality is not good to sell, reducing the high yield of maize grain water cultivation technology research, through the selection of varieties, cultivation techniques Many experiments and supporting technology demonstration, and achieved some results.
