摘要
磷是牧草重要的营养元素之一,土壤的磷肥力往往成为牧草正常生长发育的限制因子。本文综述了磷肥对牧草生长的影响,比较了磷肥与其他营养元素对牧草的综合影响,阐述了牧草对低磷胁迫的适应性,介绍了接种真菌和培育磷高效牧草品种可提高牧草对低磷环境的适应力,指出利用分子生物学技术开展磷高效牧草育种和种质资源的筛选是解决我国牧草有效利用磷素问题的关键。
Phosphorus is one of the most important nutrients for forage so that soil phosphate fertility is the limiting factor for the growth of forage. This paper summarized the impacts of phosphorus on forage,compared the effects of combined applications of fertilizers on forage,explained the adaptability of forage to low-phosphorus stress,introduced inoculation of fungus on forage and cultivation of phosphorus efficient forage varieties which can improve the adaptability to low-phosphorus. The usage of molecular biology techniques to screen phosphorus efficient forage breeding and germplasm resources is the key to solve the problem of the utilization of effective phosphorus for forage.
