龙眼高产稳产是我们多年来所追求的目标。几年来,我们对于龙眼高产稳产问题的研究,主要从如下几个方面进行的: (一)气候问题冬春的气候条件对龙眼丰歉产生很大影响,这是外因对内因所产生的影响的结果。龙眼在花芽分化花穗形成过程中的1～3月间,气温高低直接关系到当年的增减产,这为多年来所证实。龙眼是一种比较典型的亚热带果树,其对冬春气温比其他果树更为敏感。花芽分化期间需要一段较长的低温,而开花期间又要较高气温和晴朗的天气。否则对其不利。80年原
Longan high yield is our goal for many years. In recent years, our research on the problem of high and stable yield of longan has mainly been carried out in the following aspects: (1) Climatic problems The climatic conditions in winter and spring have a great influence on the apologizing and apologizing of the longan. This is the result of external factors result. Longan flower bud differentiation in the formation of flowers in January to March, the temperature level is directly related to the increase or decrease that year, which confirmed for many years. Longan is a typical subtropical fruit tree, its winter and spring temperatures are more sensitive than other fruit trees. It takes a long period of low temperature during flower bud differentiation and higher temperature and clear weather during flowering. Otherwise unfavorable to it. 80 years ago
