荔枝、龙眼是需要较高技术配套的作物,一年的管理有培养结果母枝、控梢促花、壮花保花、壮果保果四个重要环节。壮果保果是一个结果周期之中最后的一个环节,这个环节抓得好则会锦上添花,如果这个环节管理不好则前功尽弃。因此,要抓准物候期,不违农时,做好荔枝、龙眼的壮果保果工作。一、抓好辅助授粉,提高座果率荔枝早熟品种(三月红除外)将在3月上中旬开花,中、迟熟品种开花时间在3月中下旬至4月上旬。龙眼早的在3月中旬开始陆续开花,迟的则四月上中旬开花。在开花期,要努力创造良好的环境促进授粉受精,特别是2000年冬季较长时间持续高温,花芽分化不完全,早抽花穗这部分花雌花少,更要做好授粉工作,提高座果率。晴天可请蜜蜂群到果场放养,或者用鱼头、鱼肠或腐臭动物尸体招引苍蝇上树,增加授粉机会。大雨天,雨后及时摇干花盘水 Litchi, longan is the need for higher technical support for the crop, year-long management of the results of the training mother, the control of flowers, flowers and flowers, fruit Paul fruit four important links. Fruitful fruits and vegetables are the last link in a result cycle. If you grasp this link well, you will get better. If this link is not properly managed, you will have to give up. Therefore, we should grasps the phenophase, does not violate the agriculture, do the litchi, the longan fruit strong fruit preservation work. First, do a good job of secondary pollination and improve the fruit rate Early varieties of lychee (March red except) flowering in mid March, middle and late varieties of flowering time in late March to early April. Longan early in the middle of March began to flowering, late in mid-April flowering. In flowering, we must strive to create a good environment to promote pollination and fertilization, especially in 2000 winter prolonged high temperatures, flower bud differentiation is not complete, as early as pumping flower spikes in this part of female flower less, pollination should be done more to improve the fruit rate. In sunny days, honey bee swarms can be stocked in fruit farms, or flies can be attracted to dead bodies of fish heads, intestines or corrupt animals to increase the chance of pollination. Rainy day, timely after the rain shake the tray water
