Adaptability evaluation and key growth phases of UAE date palm(Phoenix dactylifera L.)in the dry-hot valley of Yunnan Province
摘要
Abstract
To evaluate the adaptability of UAE date palm(Phoenix dactylifera L.)in the dry-hot valley of Yunnan,a seven-year systematic observation was conducted on introduced date palms in Yuanjiang County,Yuxi City,Yunnan Province.The results showed excellent adaptability:the planting survival rate reached 100%,with plants overwintering safely and exhibiting strong drought tolerance.The growth and development patterns displayed distinct locally adapted features,vegetative growth showed bimodal peaks annually from February to March and June to September.Flowering occurred in the 4th year after planting,with synchronized male and female blooming from late January to late February.Fruiting began in the 5th year,reaching an average yield of 78.2 kg per plant in the 7th year.The fruit quality was high,with an edible rate of about 70%and a drying rate of about 51%.A unique phenological rhythm of"flowering at the end of the dry season,fruit expansion during the rainy season,and maturation at the beginning of the next dry season"has formed in the Yuanjiang dry-hot valley.Coupled with a"rain-fed+supplemental irrigation during critical periods"model,it can support the industrial cultivation of date palms.This study provides a scientific basis for developing characteristic fruit industries in dry-hot valley regions.关键词
