Abstract:

Taking Jintian No. 2 as material, this paper studies the storage of sweet sorghum grown under natural environment. The results demonstrated that the stalk weight, juice rate and general sugar amount descended gradually, while the sugar content of stalk juice increased gradually when the storage duration was prolonged. Climatic factor has significant influence on sweet sorghum naturally stored in the fields. In northern China, if the temperature quickly dropped to blight frost at late autumn and early winter, sweet sorghum stalk could be stored in the fields with natural frozen condition until early February next year when the average temperature rises above 0℃. During this period, the processing enterprises could harvest in the fields according to the demands of processing procedure, thus to reduce the storage space and production cost.

Key words: sweet sorghum, grown under natural environment, storage
