摘要
养分缺乏是酸性土壤的主要障碍因子之一 ,筛选和培育营养高效的作物品种是维持和提高酸性土壤生产力的重要措施。本文综述了酸性土壤上作物氮、磷、钾营养高效基因型的形态学、生理学及遗传学特征 。
Nutrient deficiencies are major limiting factors in acid soil for sustainable productivity. Morphological, physiological and genetic components of plants have profound effects on the ability of plants to uptake, transport and utilize nutrients. Characteristics of plants with high nitrogen, phosphorus and potassium efficiency in acid soils were summarized in this paper, in which the further studies of screening and breeding high nutrient efficiency genotypes suitable for acid soils were recommended.
