水稻是我国主要的粮食作物之一。它有十几种病(虫)害都因稻种带菌而初染,其中发生普遍而严重的稻瘟病、稻白叶枯病、稻胡麻斑病均有稻种带菌问题。因此稻种灭菌对防治水稻病害非常重要。但是有些病害采用常规的稻种灭菌方法不易杀死,如稻胡麻斑病菌除以分生孢子附着在稻壳表面,还能以菌丝体进入颖壳内;稻粒黑粉病菌不仅以厚垣孢子附着于颖壳内外,甚至经过动物的肠道排出不死。这些病菌给水稻生产带来极大的危害。我们考虑,棉籽硫酸脱绒,对棉籽有很好的灭菌作用,是不是水稻种子也能象棉籽硫酸脱绒那样应用硫酸处理灭菌?它对稻种发芽有无损伤?为此笔者作了水稻种子硫酸处理试验,现将处理 Rice is one of the main food crops in our country. It has more than a dozen kinds of diseases (pests) are due to the initial infection of rice species, in which the occurrence of widespread and serious blast, rice leaf blight, rice spot blotch have rice species problems. Therefore, rice germ sterilization is very important for controlling rice diseases. However, some diseases are not easily killed by the conventional method of sterilizing the rice seeds, for example, the rice rhizosphere disease is divided by the conidia attached to the surface of the rice husk, and the mycelium can also enter into the glume shell. Wall spores attached to the inside and outside the shell, and even through the animal’s intestine to discharge undead. These bacteria cause great harm to rice production. We consider that the cottonseed sulfuric acid is decoloured and has a good sterilizing effect on the cottonseed. Is it possible that the rice seeds can be sterilized by treatment with sulfuric acid like the cottonseed sulphate decoloring? Is it damaging to the rice germination? Sulfur acid treatment of rice seeds will now be processed
