在豫北潮土高产区,对花生作物施用钾、钙肥料的肥效分别进行了试验探讨,发现在该区增施钾肥、钙肥均有较好的增产作用,并对目前生产水平下的最佳施用量和对花生产量结构的影响作了分析,为科学施肥提供理论依据。
Fertilizer efficiency of peanut crop application of potassium and calcium fertilizers were experimentally studied in high yielding areas of north Henan. It was found that potassium and calcium fertilizers had a good yield increasing effect in this area, The effects of application rate and yield structure of peanut were analyzed to provide theoretical basis for scientific fertilization.
