为鉴定稀土肥料在沿海土壤棉花上的增产效果,为推广应用该项技术提供参考,我们于1989年和1990年在沿海涂地棉花生产上进行了试验研究。材料及方法试验所用的硝酸稀土微肥为河南省商丘冶炼化工厂生产,是生产稀土元素的一种中间产物;供试棉花品种为“中棉12”。试验设在浙江省三门县健跳
In order to appraise the yield increase effect of rare earth fertilizers on cotton in coastal soils and provide references for the popularization and application of this technology, we conducted experimental studies on coastal cotton production in 1989 and 1990. Materials and methods The rare earth nitrate fertilizer used in the experiment was produced by Shangqiu Smelting Chemical Plant in Henan Province and was an intermediate product of rare earth elements production. The tested cotton variety was “Zhongmian 12”. Test set in Sanmen County, Zhejiang Jian jump
