以“红提”葡萄为试材,对采用延后栽培技术栽培的甘肃耕地、非耕地设施葡萄进行公路、铁路联运物流保鲜试验。结果表明:利用自然冷凉环境,葡萄运输途中平均温度维持在3.9~8.8℃,相对湿度维持在78.9%~85.5%。运抵北京后,葡萄在0℃贮藏60d后品质新鲜,可以满足元旦、春节的市场需求。
Taking “red-grained” grapes as test material, the grapes in Gansu cultivated land and non-cultivated land cultivated with delayed cultivation techniques were tested for the fresh-keeping of road and rail transport logistics. The results showed that the average temperature of grapes was 3.9 ~ 8.8 ℃ and the relative humidity was maintained at 78.9% ~ 85.5% during natural transportation. After arriving in Beijing, grapes stored at 0 ℃ for 60 days after the quality of fresh, New Year’s Day to meet the market demand for the Spring Festival.
