富硒土壤种植白芝麻试验研究

丰城市董家镇泉南村富硒白芝麻大田种植试验,是通过在富硒土壤中施用石灰、有机肥、草皮灰等方法,以改变土壤p H值和土壤中有效硒含量,以促进和提高白芝麻吸收土壤中的Se元素,进而探索出最简便、最经济和最适合普通农户操作的富硒农产品实用生产技术。种植试验共设置5个不同处理方法和1个对照区。通过对比不同处理方法对白芝麻中Se含量的影响,试验发现最经济有效的办法是:施石灰412.5 kg/hm2与土壤混合均匀后播种,这样既能提高白芝麻的Se含量又能提高产量,操作最简单且经济成本最低。

An experimental study of white sesame planting in Se-rich soil

The Se-rich white sesame planting experiment was carried out in Quannan village, eastern part of Jiangxi Province. Through adding lime, organic fertilizer and grass ashes to Se-rich soil, we changed the pH value and the content of effective selenium to promote Se element in white sesame. This experiment is aimed to explore a simple, economic and available planting technology of Se-enriched agricultural products for farmers. We set five different treatment areas and one control area in this experiment. Comparison of the content of selenium in white sesame with different methods shows that the most economical and effective way is to plant white sesame with 27.5 kg lime per hectare. This will increase the Se element and production of white sesame, and is simple to operate, and also leads to a low cost.
