目前,我国北方推广的水稻旱育苗法和大棚温室育苗法,虽然能培育出素质好的秧苗,但成本高,操作复杂,易发生立枯病。延边科技情报所等教学、生产单位经过3年的协作,摸索出一套育秧新技术——肥水沙耕法。其优点是在育苗过程中不用温室,把种子直播在苗床里,操作简单,管理方便,比旱育苗省工50%左右。秧苗根系发育好,成苗率高,无返青期,早生快发,分蘖多,基本上不发生立枯病,产量不低于旱育苗。1985年已在吉林推广1.5万亩。
At present, the method of paddy nursery rice cultivation and greenhouse nursery method promoted in the north of our country can produce good quality seedlings, but the cost is high, the operation is complicated and the blight is easy to occur. Yanbian science and technology intelligence and other teaching, production units after 3 years of collaboration, worked out a set of new technology seedling - fertilizer and sand farming. The advantage is not in the process of nursery greenhouse, the seeds live in the seedbed, simple operation, easy management, saving about 50% of drought nursery workers. Seedling root development, high seedling rate, no turning back period, early fast hair, tiller and more, basically does not occur blight, yield no less than drought nursery. 1985 has been promoted in Jilin 15,000 mu.
