苏打盐碱稻区水稻无土育苗营养基质筛选与评价

摘要

针对吉林省西部水稻育苗床土短缺、取土困难问题,通过韩国育苗基质、腐熟物＋BTT＋EM、粉状硅酸腐植酸3种不同基质及常规育苗床土（CK）育苗效果的比较研究,发现以天然基材和有机废弃物为原料加入有益微生物生产的育秧基质即腐熟物＋BTT＋EM的育苗效果优于其他两种基质和对照,适宜在吉林省西部及东北其他类型稻作区域推广使用。%This paper aims to discuss how to solve the problem of shortage and collecting rice seedling bed soil in western Jilin Province.By seedling nursing effect research of three diffrent types of substrate（Korea seedling substrate、humus mixture＋BTT＋EM,powdery silicic and humic acid）and conventional seedling bed soil（CK）,results shows humus mixture＋BTT＋EM substrate which by using natural material and organic wastes in company with beneficial microorganism have better seedling nursing effect than the other two substrate and CK,which is more suitable to be used in western and northeast rice cropping region in Jilin Procince.
