我校土化系与西德霍因海姆大学,就“北京土壤——植物测试系统的建立与施肥建议”进行合作研究的项目,自1981年9月经中、德两国政府正式批准开始执行以来已进入第一年,试验按原计划全部展开,并已取得了预期的结果。83年度的工作是在第一年度工作基础上,根据中,德双方商定的计划,从北京、香山、大兴、朝阳、通县、昌平、永丰、板井等地选择15种不同肥力水平的农业土壤,继续开展土壤养分测试与农作物养分吸收量的相关研究,在冬小麦苗期无论化学测试与 EUF 仪测试都取得与第一年度相同的试验结果。成熟期由于温室气温过高,各小麦不能正常成熟,对试验结果有一定的影响,EUF 仪是德(?)赠送的土壤养
The project of collaborative research between the Department of Soil Chemistry of our school and the University of West Germany Hohenheim on the establishment of “Soil-Plant Test System and Proposals for Fertilization in Beijing” has been formally approved by the governments of China and Germany since September 1981 The first year since the commencement of implementation has commenced. The trial has been fully expanded according to the original plan and the desired result has been achieved. Based on the first year’s work, 83 years of work are based on the plans agreed by China and Germany to choose 15 different fertility levels from Beijing, Xiangshan, Daxing, Chaoyang, Tongxian, Changping, Yongfeng, Soil, continue to carry out soil nutrient testing and crop nutrient uptake related research, both in the winter wheat seedling chemical test and EUF instrument test obtained the same with the first year test results. Mature period due to the greenhouse temperature is too high, the wheat can not be normal maturity, the test results have a certain impact, EUF instrument is Germany (?
