【摘要】 不同植物存在营养基因型差异, 因而具有不同营养特点, 表现在不同植物对养分需求的种类、数量和养分代谢方式等存在差异。植物营养特性差异的研究,目前主要集中在根际动态过程的研究上, 包括根系分泌物和根际微生物两方面。植物营养遗传性, 在育种工作、土宜研究、环境保护等方面的应用具有广阔前景。更多还原

【Abstract】 Different plants have different characteristics on nutrient demands because of different genotypes of nutrient, which are illustrated with differences in sorts and quantity of nutrient demanded by different plants and the way of nutrient metabolism. The research on the difference of the plant nutrient characteristics at present time is mainly focused on the process of rhizosphere dynamics, including the rhizosphere microorganism and rhizosphere excreta.Research on inherited characters of phytotrophy has bright prospects in many fields such as breeding,soil adaptability , environment protection and etc.更多还原
