摘要
桃树对氮素反应敏感,提高其对氮肥的吸收利用效率是提高果实品质和实现减肥增效的基本保证。在综述氮素的存在形态和吸收形式以及不同时期桃需肥特点的基础上,对桃园施肥方式、特种肥料的开发利用等进行了总结,并探讨了提高桃园氮素利用效率的相关机制,展望了今后我国桃树高效施肥技术。
Peach is sensitive to nitrogen,improving its absorption and utilization efficiency of nitrogen fertilizer is the basic guarantee to improve the fruit quality of peach,as well as to reduce fertilizer and increase efficiency.On the basis of discussing the forms of nitrogen existing and absorption and the characteristics of fertilizer requirement of peach in different periods,this review summarized the fertilization methods and the development and utilization of special fertilizer in peach orchard,and explored the related mechanism of improving nitrogen utilization.At last,the prospect of high-efficiency fertilization technology for peach trees are forecasted,in order to promote the sustainable and efficient development of peach industry under the background of global resource depletion and environmental protection.
