摘要
2012年入春以来广西光照特少,持续低温阴天时间长,花穗抽生迟,花质量差,抽穗期遇高温,冲梢严重,开花期又遇高温天气,花期缩短(仅2-3d),对荔枝贵妃红受粉坐果影响很大。针对2012年异常气候,选取了生产上常用的抗逆境和促花保果三种叶面水溶肥,开展应对荔枝逆境的试验,对比不同处理对产量和果品的改善作用,以期筛选出效果较理想的水溶肥应用于生产。试验表明:通过在花前期、谢花后、第二次喷药、第二次生理落果前、果实转色期喷施美加富AS 500倍液,能有效提高果实糖分含量和提升果实色泽度,在产量和品质上都较对照明显突出,且能有效延长货架期。
Since spring 2012, there was less sunlight and longer low-temperature and cloudy period, which leads to later spike sprouting, poor flowering quality and serious inflorescence growth ceased. And the high-temperature in flowering period also impacts lichee fruit-setting greatly. To the question of abnormal weather in 2012, three leaf water-solution fertilizers in production are chosen as materials for an experiment to compare the impact on yield and fruit quality of lichee by different treatments so as to select ideal fertilizers in production. The results show that by the fertilizer application of Meijiafu AS in different periods can increase effectively fruit sugar content and improve fruit color, meanwhile, the yield and quality are obviously better than control group and the shelf-life can be longer.
