氮磷钾对植物侧根生长发育的影响及其生理机制

Effects of N, P, K on growth and development of plants and its physiological mechanisms

综述了氮、磷、钾供应对植物侧根生长发育,包括侧根原基的起始、侧根原基的发展出现和分生组织活化、根系伸长等方面的影响,以及这种影响与体内激素的关系,并总结了氮、磷、钾供应对根系分布的影响,为生产上进行合理施肥提供参考。

This article summarized the effects of nitrate,phosphorus and potassium on and the interaction of N, P, and K with phytohormones in lateral root growth and development： initiation, development and emergence of lateral root primordial, meristem activation and root elongation; summarized the effects of nitrate,phosphorus and potassium on root distribution in soil. It supplies certain references for reasonable nutrient management in yield.
