杂柑阳光1号裂果率研究及其在湖南怀化的引种表现
Study on the Cracking Rate of Yangguang 1 Mandarin and its Introduction Performance in Huaihua,Hunan
摘要
Abstract
This study analyzed the relationships among meteorological factor fluctuations,soil moisture fluctuations at dif-ferent depths(10-40 cm),and the fruit cracking rate after a no-rain period of ≥5 days on the basis of meteorological data from Huaihua in 2022 and 2023,as well as fruit observation data from Yangguang 1.The results revealed highly significant correlations between precipitation(r=0.991**),soil moisture fluctuations at a depth of 10 cm(r=0.974**),and the fruit cracking rate.There were significant differences in the number of cracked fruits among the different fruit load numbers(F=6.2*),but no significant differences in the cracking rate.The cracking rates caused by rainfall events in different periods also significantly differed(F=5.172*).In the anti-cracking experiment,there was no significant difference in the cracking rate between the exposed surface and the cotton felt blanket treatment.In 2023,this variety exhibited excellent fruit quality in Huaihua but had poorer cold resistance than did the main local varieties.关键词
