名贵食用香料植物香荚兰在生产上存在严重落果问题,落果率达35～50％,产量不稳定。对此,福建省亚热带植物研究所对保果稳产技术进行了三年多的试验研究,研制出8902香荚兰保果素,在香荚兰初花授粉后30天左右全面喷雾,可使落果率降低到5％左右,保果效果达88％,产量比不施药者提高48％,並对香荚兰的翌年产量、果荚鲜重和干物质含量、商品荚质量均无不良影响。福建省科委委托厦门市科委邀请有关方面专家,于1991年11月12日对本项技术进行现场验收评审,通过了技术鉴定。与会专家一致认为,该项技术研究数据可靠,8902保果素使用技术简便易行,具有较好的潜在经济效益,对今后我国香荚兰种植业的发展有积极意义,建议有关部门推广应用。
Exotic spice plant vanilla in the production there is a serious problem of falling fruit, fruit loss rate of 35 to 50%, the output is not stable. In this regard, the Fujian Institute of Subtropical Botany on the stability of the technology for more than three years of experimental research to develop the 8902 Vanilla Paulownia, vanilla early flower pollination about 30 days after the full spray, can drop fruit The rate was reduced to about 5%, the fruit effect was 88%, and the yield was increased by 48% than that of the non-applicants. No adverse effects were observed on the yield, the fresh weight and dry weight of pods, and the quality of pods. Fujian Science and Technology Commission commissioned by Xiamen Science and Technology Commission invited experts, on November 12, 1991 on-site inspection of this technology review, passed the technical appraisal. Experts agreed that the technical research data is reliable, 8902 conservation technology is simple and easy to use, has good potential economic benefits, the future development of our country vanilla cultivation has a positive meaning, it is recommended that the relevant departments to promote the application.
