地沟浸种:利用靠河塘边的场头和十边隙地,挖一条南北向,深1尺、宽2—3尺、长15尺左右的沟,锤实拍平,铺上一块无孔不漏水的塑料薄膜,上水后就可浸种。为便于换水,在地沟一端开一个小缺口,浸种时用砖头把缺口堵住。在地沟四周开一条小沟,防止雷雨冲走种子。地沟浸种的好处是:(1)不需草包、蒲包和水缸等容器。(2)便于经常换水,保持水质新鲜。(3)保温性好,接受光照面积大,水温上升快,浸种时间短,一般比缸浸要缩短一半时间。(4)便于翻种,使上下种子吸水均匀,为捂种催芽一致打基础。
Ditch soaking: the use of riverside ponds by the side and ten sides of the gap, dug a north-south, 1-foot deep, wide 2-3 feet, about 15 feet long ditch, hammer shot flat, laying a non-porous watertight Plastic film, after soaking in water. In order to facilitate water change, open a small gap at the end of the trench, soaked with a brick to plug the gap. Open a small ditch around the ditch to prevent thunder and rain washed away the seeds. The benefits of trench soaking are: (1) No straw bag, purse and tank containers. (2) to facilitate regular replacement of water, to maintain fresh water. (3) good insulation, light area to accept large, rapid rise in water temperature, soaking time is short, generally shorter than half the time to dip tank. (4) to facilitate the kind of seed, so that the water from top to bottom evenly, as cover the kind of germination consistent basis.
