氧化硫硫杆菌对水稻旱育苗床土壤调酸效果研究初报

利用硫磺粉以及土壤中的元素硫或硫的其它不完全氧化物在微生物氧化硫硫杆菌的作用下进行氧化生成硫酸,使水稻旱育苗床土壤pH=4.5—5.2之间。培育健壮秧苗,消除病虫害。试验结果表明,秧苗株高增长率是对照处理的64％,干物质积累比对照处理增加30％。

A First Report about the Changing of Soil pH after Using the Thiolacillus Thiooxidans to Seeding Bed of Rice

Sulfur Acid can be formed by Sulfur Bacterium Oxidizing Sulfur powder, pulphur in soil and Incomplete Sulfide. In this case, the soil pH of seeding bed can be kept 4.5-5.2 and the rice sprouts were changing in to sound seeding, also eliminating disease. It was shown the plan height in-creasing 64% than central and try matter increasing 30%.
