荔枝是南亚热带名优水果,大有发展前途,然而在栽培上“花而不实”问题仍很突出,为解决这一难题,我们于98—99年在海澄镇和平村陈进喜荔枝园进行了荔枝推迟花期的试验,取得良好效果。试验树选择兰竹品种21年生适龄树186株,二年累计总产19716公斤,平均年株产达53公斤,比对照平均年株产提高了36.5公斤,使这片历年不结果的荔枝园开始正常结果,主要采取以下调控措施: 一、调节培育晚秋梢为结果母枝。针对这片荔枝园结果少、梢期絮乱、树势强弱不一的特点,对抽生晚夏梢和早秋梢的植株及时施肥喷药,嫩梢期喷敌敌畏50克+杀灭菊酯15毫升+0.5％尿素治虫保
Lychee is a great tropical fruit of South Asia and has great prospects for development. However, the problem of “flowers are not real” in cultivation is still outstanding. To solve this problem, we conducted the study at Licheng Park, Chenjinxi, Heping Town, 98-99 Lychee delayed flowering test, and achieved good results. A total of 186 21-year-old tree species were selected from the experimental tree, with a total output of 19,716 kg in two years and an average annual yield of 53 kg, an increase of 36.5 kg compared with the average annual yield of the control plant. Normal results, the main control measures taken to take the following measures: First, regulate the cultivation of late autumn shoots as the result of the mother. For this piece of lychee Park results less, the chaos flocs, the tree strength of different strengths and weaknesses of the late summer pumping and early autumn shoots of plants timely fertilization spraying, shoot shoot period dichlorvos 50 grams + fenvalerate 15 ml + 0.5% urea pest control
