近几年来,由于干旱缺水,开原县稻区每年都有几千亩稻田种不上.为了探讨水田抗旱的耕作措施,我们进行了水稻旱种试验.1979年旱种78亩,其中八宝公社鲜屯二队33亩,单产812.6斤.城郊公社有8亩,单产750斤,与附近正常插秧的地块产量相同.据试验,水稻旱种在整个生育期可节水50%.泡田用水可全部节省.旱种,有调节“用水高峰”的作用,不用育苗,可节省塑料薄膜,虽然要施一些化学除草剂,但每亩成本仍降低5～7元,旱种,亩用工量减少50%,且能降低劳动强度.由此可见,在缺水年份,安排一定数量的旱种面积,既能充分发挥水的效益,又能获得较高的产量.
In recent years, due to drought and water shortage, several thousand mu of paddy fields are not planted every year in Kaiyuan rice paddy area. In order to discuss paddy field drought-resistant tillage measures, we conducted a paddy cultivation experiment .7878 acres of dry land in 1979, of which eight Bao commune fresh Tun two teams of 33 acres, yield 812.6 kg. Suburb commune has 8 acres, yield 750 kg, and the normal production of plots near the same output.According to the experiment, dry cultivation of rice throughout the growing period can save 50% of the bubble Field water can all save. Dry cultivation, there is regulation of “water peak” effect, without nursery, plastic film can be saved, although some chemical herbicides to be applied, but the cost per acre is still reduced 5 to 7 yuan, dry farming, mu labor Reduce the amount of 50%, and can reduce the labor intensity.Thus, in dry years, arrange a certain amount of dry farming area, both to give full play to the benefits of water, but also to obtain higher yields.
