试验针对北方单季稻育苗中的病害及施肥问题,进行水稻苗床灌溉施肥试验与后期本田水稻小区试验,结果表明:液、固黄腐酸灌溉肥处理下水稻苗根冠比合理、充实度好,同时还具有改良土壤和杀菌作用;苗期经黄腐酸灌溉肥处理后的本田水稻抗病性强,增产明显。 Experiments were conducted to test the disease and fertilization in the single cropping rice seedlings in the north of China. The rice seedling irrigation and fertilization experiments and the late Honda rice plot test were conducted. The results showed that the root and shoot ratio of rice seedlings under the treatments of liquid and solid fulvic acid were reasonable, But also has the effect of improving soil and bactericidal effect. The Honda rice treated with fulvic acid at seedling stage has strong disease resistance and obvious yield increase.
