在柑桔的北缘地区发展柑桔生产,普遍存在着低温冻害的威胁,这在美国、西班牙、日本等世界各地都有这种情况。我省地处柑桔的北缘地区,发展柑桔生产存在着周期性严重冻害的问题。多年的实践证明,在两次大冻间隔期间,采用各项有效的技术措施,如加强冻前预防和冻后护理,千方百计夺高产,仍然可以发展柑桔生产。现以武汉郊区发展柑桔生产为例,来说明北缘地区发展柑桔生产的一些情况。 一、武汉郊区发展柑桔生产概况
The development of citrus production in the northern margins of citrus is threatened by low-temperature frost damage, as is the case in the United States, Spain, Japan and elsewhere. The province is located in the northern edge of citrus, the development of citrus production there is a serious problem of periodic frost damage. Years of practice have proved that it is still possible to develop citrus production by adopting effective technical measures during the two major freeze intervals, such as strengthening the prevention of pre-frost and post-frost care and making every effort to achieve high yields. Take the development of citrus production in the suburbs of Wuhan as an example to illustrate some situations in the development of citrus in the northern margin. First, the outskirts of Wuhan citrus production profiles
