南岛无核荔枝控梢促花和保花保果技术的研究

Study on Keeping a Full Growth of Flowers and Fruits of Nandao Seedless Litchi(Litchi chinensis Sonn.)by Controlling Its Treetops and Hastening Its Blossom

采用不同处理组合对比分析法,根据荔枝生长物侯期,对海南省稀优品种——南岛无核荔枝进行控梢促花和保花保果研究.试验表明:A组处理效果最佳,成穗率达到85.6％,比对照增加59.8％;雌雄花比达到0.28,比对照(CK)增加了100％;座果率达到27.2％,比对照增加19.6％;单株平均产量达到20.5 kg,比对照增加150％;单果质量达38.5 g,比对照增加3.9 g.其效果极为显著.

Through comparison and analysis between different treatment groups, based on the phonological period of litchi growth, a study on keeping a full growth of its flowers and fruits by controlling its treetops and hastening its blossom was conducted to the unusual high-quality variety-Nandao seedless litchi in Hainan Province. The experiment showed that the treatment done to Group A yielded the best results, with a percentage of ear-bearing tiller reaching 85.6% , which registered a 59. 8% increase over that of control group;with a ratio of male flowers to female flowers reaching 0.28, which registered 100% increase than that of control group; with a fruit-bearing percentage rising to 27.2% , which registered 19.6% increase over that of control group; with an average yield from a single plant reaching 20.5 kg, which registered a 150% increase over that of control group;with a single fruit weight reaching 38.5 g,which registered 3.9 g increase over that of control group.
