摘要
选取9个春油菜绿肥品种进行田间试验,连续翻压两年后,测定土壤和玉米子粒中的微量元素含量,研究比较不同春油菜绿肥品种翻压对土壤微量元素含量及玉米吸收情况的影响。结果表明,中油肥1804翻压后土壤全量铁、锰和锌含量较春闲田CK处理分别提高了9.31%、5.71%、9.97%,土壤有效态铁、锰、锌含量较春闲田CK处理分别提高37.31%、62.35%、73.99%;中油肥1907翻压后土壤全铜含量较春闲田CK处理显著提高了84.29%;中油肥1901翻压后较春闲田CK处理显著提高了玉米子粒铁、锰、锌的吸收量及玉米产量和品质。不同春油菜绿肥品种翻压后土壤有效态铜含量、玉米子粒铜及锰含量与春闲田CK处理之间差异不显著;土壤有效态微量元素含量与春油菜中微量元素和土壤全量微量元素含量之间存在线性关系,且微量元素与玉米叶片叶绿素、含氮量、产量、可溶性糖、蛋白质呈显著或极显著正相关。华北地区种植并翻压中油肥1804、中油肥1901、中油肥1907能较好地提高土壤微量元素含量、生物有效性及玉米产量和品质。
The experiment selected 9 spring rape green manure varieties for field experiment.After two years of continuous returning,the micronutrients in soil and maize grains were determined.The effects of different spring rape green manure varieties returning on soil micronutrient content and maize nutrient absorption were studied and compared.The experiment results showed that the content of total iron,total manganese,and total zinc in soil after being returned by Zhongyoufei1804 were significantly increased by 9.31%,5.71%,and 9.97%respectively com⁃pared with CK treatment,and the available content of iron,manganese,and zinc in the soil were significantly in⁃creased by 37.31%,62.35%,and 73.99%compared with CK treatment.The content of total copper in soil after be⁃ing returned by Zhongyoufei1907 was significantly increased by 84.29%.Zhongyoufei1901 significantly increased the absorption of iron,manganese and zinc in maize grain and the yield and quality of maize compared with CK treat⁃ment.There is no significant difference between the soil available copper content,the copper and manganese con⁃tent of maize grains and the CK treatment after the returning of different spring rape green manure varieties.There is a linear relationship the content of soil available micronutrients between the content of micronutrients in spring rape and soil total micronutrients,and there is a significant or extremely significant positive correlation between micronu⁃trients and maize leaf chlorophyll,nitrogen content,yield,soluble sugar,and protein.In conclusion,planting and re⁃turning Zhongyoufei1804,Zhongyoufei1901,and Zhongyoufei1907 in North China can better improve soil micronu⁃trient content,bioavailability,and maize yield and quality.
