Abstract: As seedling raising development in plastic trays, it is becoming more and more difficult to get soil from field because of the destruction of vegetation and soil. Soilless substrate rice seedling raising was a new technique, which replaced the soil by high temperature fermentation substrate and avoided the work of get soil. The seedling quality, growth and yield of Zhonglongjing 1, a Japonica rice variety, in cold region of Northeast China were determined by using the YELIN brand soilless substrate in rice nursery. The study was carried out in 291 Farm, Heilongjiang. The results indicated that the application of YELIN brand soilless substrate can improve the seedling quality, promote the growth of roots, turn green early, reduce the labor intensity, save labor costs, and improve the quality of rice tiller population. Compared with the conventional nutrient soil seedling, the rice yield of soilless substrate raising seedling with machine transplanting was increased by the increase of the effective panicles, total grains and 1000-grain weight.

摘要： 东北寒地粳稻旱育秧取土难、破坏植被及耕层，水稻无土基质育秧是代替床土育秧的一种新型的育秧技术，可以解决这些难题。为明确利用烨霖基质所育东北寒地粳稻秧苗素质以及栽后水稻植株长势及成熟期产量，以中龙粳1号为试验材料，在黑龙江省二九一农场实施烨霖无土基质育秧、营养土育秧（CK）对比试验。试验结果表明，该基质可以促进水稻根系发育，提早返青生长，每盘秧苗质量轻，降低了劳动强度，节省用工成本，改善了水稻群体茎蘖质量。与常规营养土育苗相比，该基质育秧机插水稻主要通过增加有效穗数、每穗总粒数和千粒重来提高产量。
