在栽培辣椒的介质(黄棕壤土培和霍格兰营养液水培)中添加序列浓度的六价铬,根据辣椒的产量、铬累积量、还原糖含量、维生素C含量、辣椒茎叶中钙、镁、铜、锌、铁、锰等营养元素的含量,及其单株吸收量,初步确定了栽培辣椒时土壤中六价铬的适宜浓度为10ppm。
Chromium hexavalent chromium was added into medium of medium of cultivation of yellow pepper (yellow-brown soil soil culture and hydration of Hoagland nutrient solution). According to the yield of chili, the content of chromium, the content of reducing sugar, the content of vitamin C, , Magnesium, copper, zinc, iron, manganese and other nutrients, as well as their individual absorption, initially determined the suitable concentration of hexavalent chromium in soil when cultivating pepper was 10ppm.
