2011年早春我国香蕉寒害调查及寒害后恢复对策
Investigation on chilling affected banana plantations during early spring season and restoration strategies
摘要
Abstract
[ Objective ]The experiment was conducted to elucidate the effects of low temperature on banana yield during early spring season of the year 2011 in order to develop proper measures for recovering banana plantations after being injured, and to sustain banana production under cold temperature conditions. [Method]Investigations were carried out to observe the effects of chilling temperatures on banana plantations in main banana production regions viz., Guangxi, Guangdong, Hainan, Yunnan, and Fujian from March 9th to March 16th, 2011. Large, middle and small sized banana suckers and fruited plants were dissected and diagnosed under field conditions. [Result]The results showed that the fruited banana plants were more sensitive to low temperature compared to suckers. Large sized suckers responded more imperceptibly in cold weather compared to the smaller ones. The chilling damages to banana plants were more severe at high altitude compared to low altitude at same latitude. Banana plantations in central areas of Guangxi were severly affected with low temperature and showed over 50% reduction in yield. Only small and medium-sized suckers were found to be less affected under such conditions and could be planted at production. Banana plantations in the areas of Guangdong and Hainan were affected least, while those in rest of the areas performed averagely. [Suggestion]All kinds of cold-tolerant measures should be adopted to avoid the chilling induced damages to banana plantations. Some of them include covering of plants with thin plastic film in winters, increasing humidity using mist-sprayers, and wrapping fruit with cotton film. The management of banana gardens should be strengthened in order to promote the early germination and growth of suckers. The cold-tolerant variety should be screened.关键词
