土壤水分对Cd污染土壤蔬菜产量和Cd积累的影响
Effect of moisture content in Cd polluted soil on yield and Cd accumulation of vegetables
摘要
Abstract
Some typical Cd-polluted soil in Vegetable cultiVated land of Shaoguan mining area was taken and used for pot trial to study the effects of different field capacities(40% and 80%)on the yield and Cd absorption and accumulation in flower-ing Chinese cabbage( Brassica rapa Var. chinensis)and water spinach. The results showed that increasing the field capacity of soil could increase pH Value of soil and Vegetable yield,and decrease the Cd content in Vegetables. And increasing the field capacity under 2 Cd leVels,the yield of flowering chinese cabbage increased by 60. 0% and 101. 8%,and the Cd con-tent in its body decreased by 23. 0% and 168. 4% respectiVely;the yield of water spinach increased by 148. 0% and 137. 8% and the Cd content in its body decreased by 136. 4% and214. 8% respectiVely. MoreoVer,the Cd contents in two kinds of Vegetables showed Very significantly negatiVe correlation to the soil pH Value under 2 Cd leVels.关键词
