摘要:

随着畜牧业的发展,对苜蓿的种植生产提出了更高的要求。磷肥的有效利用是影响苜蓿生产力的关键因素之一。笔者系统概述了苜蓿缺磷的主要症状,不同地区施磷量和方法对苜蓿生产力的影响,施磷提升苜蓿生产力的途径,苜蓿的磷素吸收机制以及磷素与其他养分及水分互作对苜蓿生产的影响。建议今后针对不同地区的土壤理化性质,特别是有效磷含量,测土施肥,综合不同地区的结果建立气候-土壤-施肥模型,并进一步开展磷素促进苜蓿生长的生理和分子机制的研究,以期为苜蓿研究和产业发展提供有益信息。

Abstract:

With the development of animal husbandry, higher requirements are raised for the cultivation and production of alfalfa. The effective utilization of phosphate fertilizer is one of the key factors affecting alfalfa productivity. This paper outlined the main symptoms of alfalfa suffering phosphorus deficiency, the effects of phosphorus application levels and methods in different areas on alfalfa productivity, the ways to increase alfalfa productivity by phosphorus application, the mechanism of phosphorus absorption and the interaction effects among phosphorus and other nutrients, as well as water, on alfalfa production. It is suggested to measure soil for fertilization according to local soil physical and chemical properties, especially the available phosphorus content, to establish the climate-soil-fertilization model based on the results, and to study the physiological and molecular mechanisms of phosphorus promoting alfalfa growth. This paper could provide certain information for the development of alfalfa industry.

Key words: phosphate fertilizer, alfalfa, productivity, photosynthesis, root system growth, symptom of phosphorus deficiency, combined application of N,P,K
