缓释复合肥对棉花生长发育及产量的影响

Effects of Slow Release Compound Fertilizer on Cotton Growth and Yield

为考察不同缓释复合肥对棉花的生长发育及产量构成要素的影响,以等养分普通复合肥处理为对照,开展了田间小区试验。结果表明:添加了植物多酚和腐殖酸的缓释复合肥1对棉花的生长发育和产量有明显的促进作用,棉花株高、茎粗、叶片相对叶绿素含量等生长指标和果枝数、单株铃数、产量及产量构成要素明显优于其他处理的,棉花产量较添加了植物多酚的缓释复合肥2、普通复合肥处理的分别提高了7.1%、17.1%。缓释复合肥1对新疆地区减肥增产的高质量农业发展具有重要意义。

In order to investigate the effects of different slow release compound fertilizers on cotton growth and yield components,a field plot experiment is carried out with equal nutrient common compound fertilizer as the control.The results show that the slow release compound fertilizer 1 added with plant polyphenols and humic acid significantly promoted the growth and yield of cotton.The growth indexes such as plant height,stem diameter,relative content of chlorophyll in leaves,number of fruit branches,number of bolls per plant,yield and yield components of cotton are significantly better than those of other treatments.The cotton yield increased by 7.1%and 17.1%respectively compared with the slow release compound fertilizer 2 added with plant polyphenols and the common compound fertilizer.Slow release compound fertilizer 1 is of great significance to the development of high-quality agriculture in Xinjiang.
