橄榄在热带、亚热带有广泛分布,福建栽培历史悠久,品种丰富.福州地区的闽清、闽侯是福建省橄榄主产区,近十余年来,福州地区的橄揽生产得到快速发展,逐渐形成以长营、自来圆、惠圆、檀香等品种为主的种植区域.

诺瓦即克里迈丁桔和奥兰多桔柚的杂交后代桔橙2号,兼有桔、橙的优良性状.福州市农业局2000年从中国柑桔研究所引进接穗高接于以枳壳为基砧的福桔、雪柑、温州蜜柑投产树上,选择有代表性的闽侯(平原)、闽清(山地)、福清(低海拔山地)、连江(平原)、罗源(沿海山地)、晋安(中海拔山地) 等不同区域和海拔的7个试种点.高接后第二年初产,第三年投产,综合性状表现良好.现将引种情况及栽培技术报道如下.

The tests of predatory Amblyseius cucumeris to control Panonychus citri and Phyllocoptruta oleivora were studied in laboratory and fields in Fujian Province. Results showed that the control efficacy of A. cucumeris to the mites on citrus trees was 85%-95% with its release amount 900 000 larva/hm 2 in different ecological areas after 30 days, and the control time could last six months. It could be decreased the chemical pesticides dose of 40%-60%, and the commercial value of the fruit in biocontrol citri orchard was better than that of the control. The output value increased RMB 15 000 yuan/hm 2 . The optimum period of controlling two mites in different age of trees, ecological conditions, the rate of release amount of A. cucumeris and controlling release syetem were also studied in this paper.

草莓是一种上市早,营养好、效益高的高档水果,福建省自80年代开始种植草莓.近十年来,草莓生产发展很快,栽培面积不断扩大,但栽培方式单一化,以露地栽培为主,致使春季由于低温阴雨气候引起开花结果期果实腐烂的灰霉病发生严重,造成减产.近几年笔者和当地农户采用黑膜地面覆盖加小棚栽培,能有效地解决上述存在的问题,效果好,比露地增产1～1.5倍.具体做法如下:
