含聚天门冬氨酸复合肥料对菠菜生长发育的影响

The Effect of Compound Fertilizer Containing Polyaspartic Acid on the Growth and Development of Spinach

以菠菜为试验对象,不施肥和施用普通复合肥料为对照,考察了含聚天门冬氨酸复合肥料对菠菜株高、叶片展开度、叶片数、叶片平均直径、叶面积、叶体积、根系表面积、根长、根系平均直径、叶片叶绿素相对含量(SPAD值)和氮含量等指标的影响。结果表明:与施用普通复合肥料处理相比,施用含聚天门冬氨酸复合肥料处理的菠菜单株质量显著提高了60%,菠菜根长、根系平均直径和叶片平均直径分别提高了31.82%、333.77%、61.38%;含聚天门冬氨酸复合肥料处理的菠菜根系表面积达340.39 cm2。综合分析各项指标,含聚天门冬氨酸复合肥料对菠菜生长发育有明显的促进作用,能够提高菠菜产量。

Taking spinach as the experimental object,the effects of compound fertilizer containing polyaspartic acid on spinach plant height,leaf unfolding rate,leaf number,average leaf diameter,leaf area,leaf volume,root surface area,root length,root system average diameter,relative chlorophyll content(SPAD value)in leaves,and nitrogen content are investigated without fertilization and with ordinary compound fertilizer as the control.The results show that compared with the application of ordinary compound fertilizer,the application of compound fertilizer containing polyaspartic acid significantly increased the individual plant weight of spinach by 60%,and the root length,average root diameter,and average leaf diameter of spinach increased by 31.82%,333.77%,and 61.38%,respectively.The surface area of spinach roots treated with compound fertilizer containing polyaspartic acid reaches 340.39 cm 2.Based on comprehensive analysis of various indicators,the compound fertilizer containing polyaspartic acid has a significant promoting effect on the growth and development of spinach,which can increase spinach yield.
