果树体内贮存氮的研究进展

Review on the Study of Nitrogen Storage and Remobilization of Fruit Trees

果树在春季生长中能利用前一年贮存的氮,而且果树体内的贮存氮对果树的生长发育非常重要.近几年,测定果树体内贮存氮的方法已经从定性研究发展到了定量研究,从贮存氮的贮存器官、运输形式研究到了其动态变化和循环利用的年限,为果树体内氮素的研究指明了方向.这些研究为提高氮肥的利用率提供了有利的依据,并且在可持续发展和环境保护方面也起到了很大的作用.

The storage nitrogen is an important factor that influences the growth and development of fruit trees. The paper reviews the research progress and some problems that need to be solved in the nitrogen storage of fruit trees including the development of mensuration, storage organic, translocation forms and recycling time of storage nitrogen in fruit tree individuals. Finally, this paper points out some main research aspects for the storage and remobilization of fruit trees in the future.
