在水稻品种资源保存、新品种选育、种子提纯等科研工作中,往往有成百上千号材料需要播种育秧,过去一直采用分袋保管、分皿(袋)浸种和催芽、分小秧格泥浆落芽播种的方法育秧。这种方法弊病很多,如种子容易混杂和搞错,种子和种芽容易损耗,秧苗生长不整齐,杂草多,秧田操作劳动强度大,播种费工费时等等,不仅不经济,还影响科研工作的准确性。为了改革这种育秧方式,我们从1980
In the research of rice variety resource preservation, new variety breeding, seed purification and so on, there are often hundreds of materials need to sow seedlings. In the past, the seedlings have been kept in sub-bags, submerged and germinated in dishes (bags) Mud seedlings planted seedlings. This method has many disadvantages, such as easy mixing and mistakes in seeds, easy loss of seeds and seed buds, irregular growth of seedlings, more weeds, labor intensity in seedling operations, time-consuming seeding and so on, which is not only uneconomical but also affects scientific research The accuracy of the job. In order to reform this way of raising seedlings, we started in 1980
