1976～1979年间,我们在山西太谷地区石灰性褐土上,对冬小麦进行了各种微量元素的肥效试验。在试验过程中,我们分析了试验区土壤耕层中各种速效性微量元素的含量,采用小区试验和大田示范方法研究冬小麦施用锰、锌、铜、铁、钼、硼等微量元素肥料的效果。通过比较各种微量元素肥料对冬小麦增产作用的大小,基本明确了冬小麦适宜施用微量元素肥料的种类和有效施用方法,为石灰性土壤地区冬小麦应用微量元素肥料提供一定的科学依据。现将试验的情况和结果简述于下: 一、试验区土壤的供肥状况 试验设在山西太谷、晋中盆地东侧的汾河二级阶地上,为碳酸盐褐土类型。母质为黄土性物质,土壤碳酸钙含量为10％左右,土壤反应为微碱性。冬小麦的
From 1976 to 1979, we carried out fertilizer tests of trace elements on winter wheat in calcareous cinnamon soil in Taigu, Shanxi Province. During the experiment, we analyzed the contents of various available trace elements in soil plow layer in the experimental area and studied the effect of applying trace element fertilizers such as manganese, zinc, copper, iron, molybdenum and boron by winter wheat experiment and field demonstration method . By comparing the effect of various trace element fertilizers on winter wheat yield increase, the types and application methods of suitable trace element fertilizers for winter wheat were basically clarified, which provided scientific basis for applying trace element fertilizers to winter wheat in calcareous soil area. Now the conditions and results of the experiment are briefly described as follows: 1. The test of fertilizer supply to the soil in the experimental area is located in the second terrace of Fenhe River on the east side of Taigu, Shanxi and Zhongzhong basins, and is a type of carbonate-brown soil. The parent material is loess material, soil calcium carbonate content of about 10%, soil reaction is slightly alkaline. Winter wheat
