密度和施肥对春小麦产量及品质影响的研究

Study on Effects of Density and Fertilization on Yield and Quality of Spring Wheat

密度和施肥是影响春小麦产量和品质的重要因素，密度与产量关系密切，密度取决于品质特性和施肥水平，密度和施肥具有显著的互效作用。在同一适宜密度条件下，小麦的产量和品质基本上是随施肥量的增加而增加，当施肥达到一定量时，又呈下降趋势。试验认为，只有密度和施肥统筹兼顾，才能保证小麦高产优质。

The density and fertilization were important factors influencing the yield and quality of spring wheat. The relation ship between density and yield was close. The density was dependent on characteristics of variety and level of fertilization. The density and fertilization were benefited each other obviously. The yield and quality of wheat have been increased by increasing fertilization. When the fertilization surpassed a certain level the yield and quality of wheat were both decreased. The experimental data showed that the optimum density and fertilization were necessary for assuring to get higher yield and good quality of wheat.
