土壤pH对植物生长发育影响的研究进展

土壤pH对植物的生长发育影响显著,主要表现在直接影响和间接影响两个方面。间接影响主要是通过对土壤物理、化学及生物学特性的影响而影响植物生长,直接影响主要表现在对植物外观形态、物质代谢、生长发育以及品质和产量等方面。为提高土壤肥力,促进植物生长发育,酸碱性失调土壤的改良途径与土壤pH对植物的影响机理等是当前亟待加强研究的问题。

Research Progress on Effects of Soil pH on Plant Growth and Development

Growth and development of plant are seriously affected by the soil pH. The effects of soil pH on growth and de velopment of plant represent direct aspect and indirect aspect. The indirect one mainly lies in three points as following： effects on physical, chemical and biological properties of soil. On the side of direct aspect, it shows on appearance, material metabolism, growth and development, quality and yield of plant. In order to enhance soil fertility and promote growth and development of plant, it is essential and urgent to study the improvement approach of pH maladjusted soil and the effect mechanism of soil pH on plant.
