长期施用含氯化肥对大豆生育及养分吸收的影响

从1984年起，在沈阳农业大学棕壤上没有氮化肥长期定位试验。结果表明，长期施用含氯化肥在大豆整个生育期内可促进株高、茎粗、根系等地上部及地下部的生长，氯对大豆氮、磷养分的吸收无明显影响，对钾的吸收有 促进作用。

Effects of Long- term Application of Chlorine-containing Fertilizers on the Growth and Nutrient Assimilation of Soybean

A long-term location test for chlorine-containing fertilizers was set up in brown earth in 1984. The results indicated that a long-term application of chlorine-containing fertilizers could promote the increase of plant height, the thickness of the stems, length of root system and other parts of a plant above and under the ground. Chlorine has not obvious effects on the N, P assimilation of soybean, but promotes the assimilation of K.
