根际土壤的pH环境对植物养分的有效性起着十分重要的作用。近年来的研究表明,某些豆科作物的敏感品种在土壤磷供应不足时,根际有趋向酸化的现象。禾谷类作物有无此现象,它们与土壤中难溶性磷利用率的系关如何?都是值得研究的问题。
The pH environment of rhizosphere soil plays an important role in the availability of plant nutrients. In recent years, studies have shown that some of the sensitive varieties of leguminous crops in the supply of soil phosphorus is insufficient, the rhizosphere tends to acidification phenomenon. Whether cereal crops have this phenomenon and how they are related to the availability of insoluble phosphorus in soils are all worth studying.
