茶叶是百色地区一项商品生产,近年来发展迅速,经济效益高。茶树与其他植物一样,生长发育与气象条件十分密切。干热风是影响本地茶叶产量的主要问题。本文根据张荣伦同志于一九八四—一九八六年四—六月在百色茶场进行物候观测的资料,以及该场科研室一九八○—一九八六年云南大叶茶逐月青茶叶产量和该场的气象资料进行讨论分析。茶树的干热风为害茶树是喜温暖湿润的亚热带植物,一九八四年四月三日十六至二十时,百色茶场气温为33.1～35℃,空气相对湿度为15—17％,西北风五级左右,第二天茶树嫩芽出现枯死现象。经调查看到,不同坡位、坡向受害程度不同。东坡、北坡低洼地或有杂草覆盖的茶园 Tea is a commodity production in Baise area. In recent years, it has developed rapidly and has high economic benefits. Tea tree and other plants, growth and meteorological conditions are very close. Dry hot air is the main issue affecting local tea production. This article is based on the data from Comrade Zhang Ronglun’s phenological observations at the Baise Tea Plantation in 1984-86 and the monthly research results of the 1980-2006 Yunnan Daye Tea Tea yield and the meteorological data of the field for discussion and analysis. Tea tree dry hot wind damage Tea is a warm and humid subtropical plants, April 3, 1984 at 16:00 to 20:00, Baise tea plant temperature of 33.1 ~ 35 ℃, air relative humidity of 15-17%, the northwest wind Five or so, the next day withered tea shoots appear dead phenomenon. After investigation, we can see that different slope positions have different degrees of damage. Dongpo, northern slopes or weeds covered tea plantations
