通过对3个弱筋小麦品种的5个不同施氮量的研究,探索出弱筋小麦对氮肥量的需求。研究结果表明,弱筋小麦产量与施氮量呈正相关关系,但品质与施氮量呈负相关关系。综合分析,在磷、钾肥确定的条件下,施纯氮量120kg hm-2的处理,既兼顾了产量又确保了弱筋粉小麦的优良品质。 Through the research on five different nitrogen application rates of three weak gluten wheat varieties, the demand for nitrogen fertilizer for weak gluten wheat was explored. The results showed that the yield of weak gluten wheat had a positive correlation with the nitrogen application rate, but the quality had a negative correlation with the nitrogen application rate. Comprehensive analysis, in the phosphorus, potassium fertilizer conditions, the application of nitrogen content of 120kg hm-2 treatment, both yield and ensure the fine quality wheat flour.
