摘要
蔬菜施肥推荐需要了解作物的养分需求和收获部分带走的养分量。根据京郊地区露地蔬菜生产的调查结果,结合已有的相关文献和专家意见,建立了京郊露地主要栽培蔬菜的包括目标产量、经济产量、残茬产量、养分需求量、经济产量部分养分含量、作物残茬养分含量等内容的数据库。
When calculating fertilizer recommendations and nutrient balances, growers and advisers usually do not do site specific measurements but use data from look up tables. Therefore a database on nutrient contents of Biomass yield, marketable yield and harvest residues of 13 open field vegetable crops is presented. This database was compiled using resuits from our experiments and investments, and modified some of them according to recent literature and experts ' recommendations.
