钾是大豆生长发育所必需的重要营养元素之一,其作用如何?尚不十分清楚。因此从1980年开始,在所内及宁陵县北刘农科站进行了盆栽试验,在新郑、宁陵、郑州市郊、泌阳、驻马店镇、遂平、项城等基点进行了一系列的田间试验。通过试验,初步明确了钾肥对大豆的增产效果与施用技术,为推广使用钾肥提供科学依据。
Potassium is one of the important nutrients necessary for the growth and development of soybean. What is its role? It is not yet clear. Therefore, from 1980 onwards, a pot experiment was carried out in this station and at North Liu Agricultural Station in Ningling County. A series of field experiments were conducted on the basis points of Xinzheng, Ningling, Zhengzhou suburbs, Biyang, Zhumadian, Suiping and Xiangcheng. Through experiments, the initial effect of potassium fertilizer on soybean yield and application technology were clarified, which provided a scientific basis for promoting the use of potassium fertilizer.
