关中东部三门峡库区是我省油料主产区之一。我师库区各团场同黄、渭、洛三河汇流处的河流泛滥地,绝大部分是近代河漫滩淤积土,砂碱地较多,肥力较低,土壤缺磷,致使油菜产量不高。针对这一问题,几年来我们对油菜施磷的增产效果,进行了一些试验研究。试验结果表明,不论是粘土、壤土或砂土,不论是壮地、薄地或盐碱地,施磷

Guanzhong Sanmenxia reservoir area is one of the main fuel-producing areas in our province. All the reservoirs in our reservoir area were flooded with rivers in confluence of Huang, Wei and Luo rivers. Most of them were silt soils of modern river floodplain with more sand and alkali, lower fertility and lack of phosphorus in soil, resulting in low yield of rape. In response to this problem, in the past few years we rape phosphorus yield stimulation effect, conducted some experimental research. Test results show that, whether clay, loam or sand, whether it is strong, thin or saline, phosphorus
