富硒土壤资源开发利用种植试验研究——早稻富硒种植试验研究初报

Study on development and utilization of Se-rich soil resources:As a preliminary report of study on early rice cultivating experiment in Se-rich soil

高安市建山镇牌楼村早稻富硒种植试验,是通过在富硒土壤中施用生石灰、有机肥、火土灰等方法,研究促进和提高早稻米吸收土壤中的硒元素,探索最简便、最经济和最适合普通农户操作的富硒稻米实用生产技术。本次种植试验采用对比试验,共设置3个不同处理试验区和一个对照区,每种处理设置2次重复小区。通过对比不同处理,早稻富硒种植试验结果,发现处理试验1(即亩施67 kg生石灰,常规施肥和管理)是目前试验中提高早稻米硒元素含量最有效的一种技术方法。

The early rice cultivating experiment operated in Pailou village, Gao＇an city, Jiangxi province, was carried out by applying mixed caustic lime, organic fertilizer and coal ash in Se-rieh soil to promote and enhane the early rice to better absorb selenium in soil and choose an easier operated, economical and suitable cultivating technique for the major portion of local famers. In the cultivating experiment the correlative experiment was applied. Three different processing experiment areas and one standard correlative cultivating area as well as two repeated experiment subareas for each processing experiment area were designed. Comparing the experimental data of early rice cultivating in Se-rich soil, it is found that the processing experiment area 1 （where 67 kg/Mu of coustic lime was applied with conventional fertilization and mangement） is the most effective technic method to enhance Se-content of the early rice.
