庄河市水田面积 2 7万ｈｍ2 ,其中山区和大灌区的远、高、漏地段水田 4 6 6 7ｈｍ2 。这些水田由于春季水源短缺 ,历年水稻产量低而不稳 ,一般公顷产量仅在 2 2 50～ 30 0 0ｋｇ。为了改变这些水田的低产局面 ,近年 ,我们与水利部门配合 ,进行了水稻旱种水管栽培技术研究。从 Zhuanghe has a paddy field area of ​​27,000 hm2, of which 466,7hm2 are paddy fields in the far, high and leaking areas of the mountainous and the large irrigation areas. Due to the shortage of spring water and the low and unpredictable annual output of paddy rice, paddy fields generally yield only 2250-3000 kg. In order to change the low-yielding situation of these paddy fields, in recent years, we cooperated with the water conservancy department to carry out the research on cultivation technology of dry-type water pipes for rice.
