硼、镉元素及其交互作用与油菜产量和品质

硼和镉两种元素是影响油菜产量和品质的两个重要因素.硼是植物生长所必需的微量元素,施硼是油菜种植的必需环节;镉是植物生长的非必要元素,易在油菜体内富集,可能通过食物链危害人体健康.本文主要从镉含量与油菜食品安全品质角度考虑,阐述了油菜对镉的积累和耐受机制;同时,概括了前人总结的硼对油菜的产量和品质的影响.最后,结合本人研究区广西地区土壤有效硼含量低,全镉含量高的现状,提出运用硼镉交互作用机理,通过施加适量硼肥,提高油菜的产量和品质,消除土壤镉的潜在危害,从本质上改善该地区土壤存在的低硼高镉现状.

Effects of boron and cadmium and B-Cd interaction on seed yield and quality of canola

Elements Boron and Cadmium play important roles in the yield and quality of canola crop. Boron is an essential trace element for plant growth, and in order to benefit canola growth, we need to apply Boron to it. While Cadmium is one of the nonessential elements for plant growth, it tends to accumulate in canola plant and may effect people's health through food chains. From the point view of Cadmium concentration and food safety of canola, this paper illustrated a mechanism of canola enduring and accumulating cadmium. A brief literature review on effects of boron on seed yield and quality of canola was also made. Based on the field conditions of our research region Guangxi, where effective Boron is low and total Cadmium is high in soil, and boron-cadmium interaction theory, we propose to apply adequate Boron fertilizer in field to help improve yield and quality of canola, and minimize potential hazard of Cadmium.
