水稻受亚铁中毒危害是我省湿田土壤中常见的一种稻障碍。据有关资料报道,当土壤中缺钾和偏施化学氮肥时,水稻更易受亚铁中毒的危害,其病症往往受环境因素的干扰而发生变化。如单凭病症形态诊断则易误诊。根据浙江省农业大学土化系王人潮同志提出的一种具有较好诊断性的化学速测法——0.1％邻菲罗林直接浸提法及诊断指标。经我所重复测试,此法能确诊该病。
Paddy rice is affected by ferrous poisoning is a common paddy obstacle in wetland soil in our province. According to relevant information, rice is more susceptible to ferrous poisoning when the soil is deficient in potassium and biochemical nitrogenous fertilizer is applied, and the symptoms of the disease are often disturbed by environmental factors. If the diagnosis of symptoms alone is easy to misdiagnosis. According to the rapid diagnostic method of chemical rapid test proposed by Comrade Wang Renchao, Department of Soil Science, Zhejiang Agricultural University, 0.1% o-phenanthrene direct extraction method and diagnostic index. After I repeat the test, this method can confirm the disease.
