我省南部处于热带季风气候下,干湿季分明。干燥的冬季一般都在℃以上,同时有一段时间低温,对荔枝花芽的形成最为有利。春天转暖日照长,有利于荔枝的开花和授粉。四至六月雨季到来,有利于荔枝果实发育。五至十月采果后,正值雨季,也有利于来年的果稍形成。全省还有许多适合荔枝生长的微酸性的红壤和冲积土,所以荔枝在这些热带地区普遍生长良好。但由于种种原因,在荔枝生产中也出现大小年,即一年结果;一年不结果或结果很少的现象。归纳起来,主要有以下几种情况: 1.一些年开花多,另一些年则开花少。
The southern province is in a tropical monsoon climate, wet and dry seasons. Dry winter are generally above ℃, while a period of low temperature, the formation of litchi flower buds the most favorable. The warmth of spring sunshine, is conducive to the flowering and pollination litchi. The arrival of the four to six rainy season is conducive to the development of litchi fruit. From May to October after the fruit harvest, coincided with the rainy season, but also conducive to the fruit of the coming year slightly formed. There are also many slightly acidic red soils and alluvial soils suitable for the growth of lychee in the province, so litchi generally grows well in these tropical regions. However, due to various reasons, the size of litchi also appears in the production of litchi, that is, the results of a year; a year of no results or few results. To sum up, there are mainly the following situations: 1. Some flowers bloom more in some years while others bloom less in others.
