我省水稻育秧向受立枯病等为害,严重影响培育全苗壮苗。自1974年以来应用敌克松杀菌剂处理秧田土壤,并在较大面积上改湿润育秧为半旱育秧和旱育秧,基本解决了水稻育苗中三病(立枯病、青枯病、绵腐病)、一弱(弱苗)的问题,成为抗御低温冷害,促进大面积均衡增产的有效措施。由于敌克松成本较高,在生产上不易全面推广。我们于1976年秋季和1977年春季,先后与辽阳市农业局和沈阳市郊各县区试用石油化工厂排弃的废物糠醛渣处理秧田土壤,取得了较好的防病和培育壮秧的效果。现将两年的研究结果介绍如下:
Rice cultivation in our province to damping-off blight and other damage, seriously affect the nurturing seedlings strong seedlings. Since 1974, the application of antimicrobial Nisuke fungicide treatment of seedling soil, and in a larger area on the wetting and transplanting seedlings for semi-dry and drought nursery seedlings, the basic solution to three diseases in rice seedling (blight, bacterial wilt, cotton rot Disease), a weak (weak seedlings), to become an effective measure to resist chilling damage and promote large-area and balanced production. Due to the high cost of the enemy Kesong, not easy to promote in the production. In the autumn of 1976 and the spring of 1977, we tried furfural residues, which were disposed of by the petrochemical plant wasteland alfalfa slag, to Liaoyang Municipal Bureau of Agriculture and counties in the outskirts of Shenyang respectively to treat the seedling soils and achieved good results in preventing disease and cultivating strong seedlings. Now two years of research results are as follows:
