1979年,我们和沈阳冶炼厂农场共同进行水稻温室营养液育苗试验,取得了成功,共育两批稻苗,插秧面积9.1亩。用这种方法培育出的秧苗与一般生产田35天秧龄的秧苗长相近似,4张多叶片,株高4寸以上,茎扁蒲,叶色绿中带黄,叶片挺拔健壮,根系发达,插后缓苗快,分蘖早,并适合机械插秧。还能克服温室无土育秧二叶小苗素质较差,插秧本数偏多,插后缓苗较慢的缺点。现将我们的具体作法简介于下:
In 1979, we carried out the experiment of rice seedling nutrient solution in greenhouse with Shenyang Smelter Farm successfully. Two batches of rice seedlings were planted together and the planting area was 9.1 mu. The seedlings nurtured by this method are similar in appearance to the seedlings of 35 days seedling age in the general field of production. Four multi-leaf plants with a plant height of 4 inches or more are planted with stems and yellow leaves. The leaves are tall and straight, After Huanmiao fast, tillering early, and suitable for mechanical planting. But also to overcome the greenhouse soilless seedlings two leaflets poor quality, more than the number of transplanting seedlings, after plugging Huanmiao shortcomings. Here is a brief summary of our concrete approach:
