浙江省杨梅气候生态区划的研究

Climatic ecological regionalization of bayberry in Zhejiang Procince.

杨梅是浙江省的重要水果之一,1989年产杨梅6万吨。由于季风气候的不稳定性,气象灾害频繁,夏季的干旱,冬季的低温和杨梅果实生长期的少雨都严重影响杨梅的产量。本文根据近几年对杨梅研究的最新成果,讨论了适宜杨梅生长的气象生态条件,影响杨梅品质的主要气象因子以及杨梅地理分布现状。最后根据影响杨梅品质和产量的主要因子划出三个一级区,八个亚区,并讨论了各区的气候特点和发展杨梅生产时应注意的问题。

The bayberry is of great importance in the fruit production of Zhejiang Province. In 1989. the annual yield of bayberry fruit was about 60 000 t. The meteorological disasters nre frequent, because of unstable monsoon climate in the Province. The disasters, such as drought in the summer, low temperature in the winter and insufficient rain during the fruit growing season , affect seriously the yield of bayberry. According to some research results on the bayberry in recent years, the agroclimate for baybrry growing and the effect of climatic ecological factors on the fruit quality, and present state of the geographical distribution of bayberry are discussed in this paper. As a result, three climatic eclolgical regions are identified, some of which are divided into subre-gions based on precipitation, low temperature and drought damage. The points to be noted as to the climatic characteristic of the regions and in bayberry production are discussed.
