龙眼是一种多花果树,花穗着生在前一年的新梢顶端。当树体营养状况良好,气候适宜时,每个新梢都能抽生花穗、开花结果。经研究龙眼母枝多来源于上年之夏梢和秋梢,其中,采果后抽发的秋梢占一定的比例。据1985～1987年观察:采后秋梢径粗达到0.6厘米以上者占49.7％(其中0.6～0.8厘米占25％,0.8厘米以上占24.7％)均能形成花穗,其成穗率在50％左右.龙眼果实的适时、正确采收,不仅减轻了树体负担,使营养集中于恢复树势、萌发新枝梢,而且采果后的9～11月份,平均气温在25℃左右,非常
Longan is a multi-flower tree, flower spike born in the previous year’s top tip. When the tree nutrition in good condition, the climate is appropriate, each shoot can sprout spikes, flowering results. The study of longan mothers and more from the previous year’s summer tip and autumn shoots, of which, after harvesting the autumn shoots accounted for a certain percentage. According to the observation from 1985 to 1987, the percentage of spikelets of spikelets after harvesting was 49.7% (0.6% to 0.8% for 25% and 0.8% for 24.7%), %. Longan fruit timely, correct harvest, not only lightened the burden on the tree, so that nutrition focused on the restoration of tree vigor, germination of new shoots, but after picking the fruit from 9 to November, the average temperature at about 25 ℃, very
