本文运用条区设计设置的试验结果,分析了氮磷化肥对籽粒产量、蛋白质含量和蛋白质产量的主效和互作。氮对三个指标的影响都极显著;磷对籽粒产量和蛋白质产量影响极显著,而对蛋白质含量无显著影响;氮磷对蛋白质含量的影响无显著交互作用,而对籽粒和蛋白质产量的影响都有显著互作效应。对籽粒产量和蛋白质产量进行综合分析,最优氮磷组合为N_(12)∶P_(12)或N_(16)_∶P_8(公斤/亩),就此还分析了氮、磷取不同水平时氮磷的最优组合问题。籽粒产量、蛋白质含量和蛋白质产量间两两呈极显著正相关;但蛋白质产量与籽粒产量的相关系数高于蛋白质产量与蛋白质含量的相关系数。说明通过提高籽粒产量比通过提高蛋白质含量来提高蛋白质产量较为容易。但也存在通过栽培措施使籽粒产量和蛋白质含量同时提高的可能性。
In this paper, the experimental results of the design of strip design were used to analyze the main effects and interactions of nitrogen and phosphorus fertilizers on grain yield, protein content and protein yield. The effects of nitrogen on the three indexes were very significant. Phosphorus had a significant effect on grain yield and protein yield, but had no significant effect on the protein content. The effect of nitrogen and phosphorus on protein content had no significant interaction, but the effect on grain and protein yield All have significant interaction effects. According to the comprehensive analysis of grain yield and protein yield, the optimal combination of N and P was N 12: P 12 or N 16 16:68 (kg / mu) The Optimal Combination of Nitrogen and Phosphorus. There was a significant positive correlation between grain yield, protein content and protein yield, but the correlation coefficient between protein yield and grain yield was higher than that between protein yield and protein content. This shows that it is easier to increase the protein yield by increasing the grain yield than by increasing the protein content. However, there is also the possibility of simultaneously increasing the grain yield and the protein content by cultivation measures.
