摘要
针对辽宁省各水稻主产区的典型水稻土,采用水浸法测定硅素含量,结合盆栽试验研究硅素肥力与产量的关系。结果表明,所有土样施硅肥处理的水稻产量均有增加;不同土样施硅肥的增产率不同;水浸法土壤硅素测定结果适用于评价辽宁地区水稻土硅素肥力状况。
The immersion method was used to study the level of silicon in the soils of main flee production areas in Liaoning province. And the results were combined with field experiment to study the relationship between the output of the rice and the silicon fertilizer level. The results showed that all silicon fertilizer application treatments increased the output of rice in different places; the increase rate was different in in different places; the immersion method was an applicable＇ and reliable method to evaluate the silion fertilizer level of paddy soil in Liaoning province.
