在杨梅硬核期开始薄膜棚架避雨栽培,比较避雨栽培与露地栽培温湿度,杨梅生长与果实品质的差异。结果表明,薄膜棚架避雨栽培的平均温度比露地处理高0.17℃,平均相对湿度比露地处理高0.87%;杨梅的叶长、叶宽比露地处理显著低9.08%和9.6%,叶厚比露地处理显著低5.94%。果实烂果率和落果率分别比露地处理显著低51.59%和55.13%,果实转色期和成熟期比露地处理提早2~5d;单果质量比露地处理显著高5.76%;果实横径、纵径分别比露地处理高4.7%和1.65%;色差L、色差b分别比露地处理高5.4%和37.75%;总糖、可溶性固形物和维生素C分别显著比露地处理高2.28%、2.11%和3.05%;硬度和可滴定酸分别比露地处理低2.30%和3.36%。薄膜棚架避雨可明显提高杨梅栽培的经济效益。 During the hardwood period of Myrica rubra, film shelter shelter was cultivated, and the differences of temperature and humidity between shelter and open field cultivation, growth and fruit quality of bayberry were compared. The results showed that the average temperature of rain shelter was 0.17 ℃ higher than that of open-field and the average relative humidity was 0.87% higher than that of open-field treatment. The leaf length and leaf width of bayberry were significantly lower 9.08% and 9.6% Dew treatment was significantly lower by 5.94%. The rotten fruit rate and fruit drop rate were 51.59% and 55.13% lower than the open field treatment respectively. The fruit color and maturation stage were 2 ~ 5 days earlier than the open field treatment. The fruit weight was 5.76% higher than the open field treatment. Respectively, were higher than open-field treatment 4.7% and 1.65% respectively; color difference L and color difference b were 5.4% and 37.75% higher than open-field treatment respectively; total sugar, soluble solids and vitamin C were 2.28%, 2.11% and 3.05% ; Hardness and titratable acid were 2.30% and 3.36% lower than the open-field treatment respectively. Film shelter shelter can significantly improve the economic benefits of bayberry cultivation.
