锌肥在沿江灰潮土和石灰岩母质(岩)发育的水稻土上应用的增产效果,从理论和生产实践上已被农业科技工作者所证实,但应用在花岗片麻岩和第三纪红砂岩发育的水稻土上的研究报告甚少。针对我县水稻有效锌含量较低,主要水稻土壤类型又多为花岗片麻岩和红砂岩风化物发育的实际情况,我们1982—1986年在这类土壤上进行了早稻
The application of zinc fertilizer to paddy soil developed along the calcareous soil and limestone parent material has been confirmed by agricultural scientists and technologists in both theory and practice. However, it has been applied to granite gneiss and Tertiary There are few reports on paddy soil with red sandstone. According to the fact that the effective zinc content of paddy in our county is relatively low, the main types of paddy soil are mostly the actual situation of the development of the granite gneiss and the red sandstone weathering material. In 1982-1986,
