在县域范围内,选取12个有代表性的试验点,分析了有机质、全氮、硝态氮、有效磷、速效钾与济麦22产量与品质的关系。结果表明:土壤氮素水平是决定济麦22能否获得高产的关键;土壤磷、钾肥水平是决定籽粒蛋白质品质的重要因素,籽粒湿面筋对土壤养分的需求与蛋白质类似,主要差异体现在对土壤硝态氮含量的需求上。在保证高产的条件下,磷钾的配合施用,尤其是钾肥的施用是济麦22获得优质的关键。本试验条件下,样点9的土壤肥力水平最值得推荐。
In the county area, 12 representative test points were selected to analyze the relationship between yield and quality of organic matter, total nitrogen, nitrate nitrogen, available phosphorus, available potassium and Jimai 22. The results showed that soil nitrogen level was the key to determine whether the yield of Jimai 22 was high. The levels of soil phosphorus and potassium fertilizers were the important factors that determine the protein quality of grain. The requirements of wet gluten on soil nutrients were similar to that of protein. Demand for soil nitrate nitrogen content. In ensuring high yield conditions, the combination of phosphorus and potassium application, especially the application of potassium is the Jimai 22 access to the key to high quality. Under the experimental conditions, the soil fertility level of sample 9 is the most recommended.
