农药CuSO4处理对空心菜生长及营养品质的影响
The Effects of Pesticide CuSO4 on the Growth,Nutrition and Quality of Ipomoea aquatic
摘要
Abstract
With the increase of focus on food safety,copper agents which have the characteristics of pollution-free,no re⁃sistance etc. are widely used in organic agricultural production. Whether the extensive application of copper agents will bring influence on the yield and quality of foods or not is noteworthy. To inspect this influence,the changes of seed ger⁃mination,seedling growth and vegetable quality of Ipomoea aquatic under CuSO4 processing will be assayed in this pa⁃per.Results showed that CuSO4 treatment not over 1 mM had no obvious effect on seed germination rate,but would re⁃duce seed germination quality. CuSO4 treatment not over 9 mM had no obvious effect on seedling growth,photosynthesis, yield and nutrient content. CuSO4 treatment would increase copper accumulation in I. aquatic seedlings,and copper would accumulate preferentially in roots. Copper content in leaves and stems in the treated I. aquatic seedlings would not exceed the national standard,but it would exceed the standard in roots when CuSO4 was not less than 3 mM. CuSO4 treatment would reduce the nitrate reductase activities which led to the nitrate accumulation to the severe pollution level in I. aquatic seedlings. This would reduce the vegetable quality and enhance the human cancer risk.关键词
