白菜型油菜是我省高寒地区重要的油料作物。本试验设在同德县巴滩草原上的省牧草良种繁殖场,由该场与省农林科学院土肥所按全国化肥网统一试验方案协作进行。目的是探讨该地区氮、磷化肥对白菜型油菜的肥效及适宜的用量和比例,为推荐施肥、搞好化肥的合理分配和施用,提高作物产量和经济效益提供科学依据。经过一年试验结果表明:该地区氮素虽是一个严格控制的因子,但在多年偏施磷肥,少施或不施氮肥的情况 Cabbage-type rapeseed is an important oil crops in the alpine region of our province. This experiment is located in Tongde County Bantan grassland on the provincial forage breeding farms, by the field and the Provincial Academy of Agriculture and Forestry soil fertilizers according to the National Fertilizer Network unified pilot program in collaboration. The purpose is to explore the effect of nitrogen and phosphorus fertilizers on the capacity and proportion of cabbage rapeseed in the region to provide scientific basis for recommending fertilization, improving the rational distribution and application of chemical fertilizers and increasing crop yield and economic benefits. After a year of test results show that: Although nitrogen is a strictly controlled factor in this area, but in the years of partial phosphate fertilizer, with or without nitrogen fertilizer
