稻苗立枯病除了采取药剂防治,调节肥、水供应,调节温度和通风等综合防治措施外,调整床土酸度也是控制立枯病的一个有效办法.据试验:用胡敏酸把塑料育苗盘土壤调整到微酸性(pH5.5),基本上可免除立枯病的危害.调整塑料盘育苗土壤酸度(简称调酸,下同),同秧田苗床土调酸有很大差别,还缺乏实践经验.为了减少盲目性,应当通过试验取得成效后再应用于生产实际.一、苗床土调酸范围和调酸土层厚度
Rice seedling blight in addition to take preventives, regulating fertilizers, water supply, temperature and ventilation and other integrated control measures, the adjustment of bed soil acidity is also an effective way to control the damping-off disease.According to the test: Humic acid plastic seedlings Plate soil adjusted to a slightly acidic (pH5.5), basically free from the danger of blight.Adjustment plastic plate seedling soil acidity (referred to as acid, the same below), with seedling soil acidity are very different, but also the lack of Practical experience. In order to reduce the blindness, should be achieved through the trial and then applied to the production of practical.
