不同品种樱桃番茄在粤东北山区设施栽培对比试验OA

To address the facility environmental characteristics of low light and high humidity during winter in the mountainous areas of north-eastern Guangdong,as well as the monoculture issue of dominant cherry tomato varieties,this study aimed to screen high-quality new cherry to-mato varieties suitable for local facility cultivation.Using typical facility greenhouses in the mountainous areas of northeastern Guangdong as the experimental base,three cherry tomato varieties:Yuekeda 101,Yuekeda 202,and Yuekeda 206(bred by the Institute of Facility Agriculture,Guangdong Academy of Agricultural Sciences),were tested under substrate cultivation.Systematic comparisons were conducted on phenological stages,plant growth traits,disease resistance,yield,and fruit quality.The results showed that all three varieties exhibited favorable comprehen-sive traits:Yuekeda 101 demonstrated significantly earlier phenology,with 5-8 days shorter duration from transplanting to first harvest com-pared to other varieties.At 42 days post-transplanting,its plant height(169.13 cm),stem diameter(0.93 cm),and leaf area(1 228.96 cm2)significantly outperformed others.Yuekeda 206 achieved the highest yield(69 601.95 kg/hm2)and the longest harvesting period(113 days).Yuekeda 202 produced the largest single fruit weight(19.76 g)but showed weaker crack resistance.All three varieties had soluble solids con-tent(SSC)exceeding 8.30%,with Yuekeda 206 having the highest sugar content(8.70%).Yuekeda 206 is recommended as the primary vari-ety for facility cultivation in northeastern Guangdong due to its high yield,extended harvest window,and superior commercial fruit quality.Yuekeda 101 is ideal for early-maturing cultivation,while Yuekeda 202 suits short-term intensive production but requires enhanced cracking prevention strategies.This study provides technical support for breaking foreign variety monopolies and establishing a localized cultivation sys-tem.
