Process-Technological Evaluation of Harvesting Hemp in Winter

摘要

该项目的目的是为德国在冬天麻收获可能性的评价，认为其平均 气候条件。一个收获的前提条件是，大麻吸管达到水分含量低， 适合存储。为了这个目的，麻茎是波茨坦麻场定期采样（德国）2010一月至2011三月来确定他们的干物质（DM)的含量。二月 的麻茎端达到90%的干物质含量。获取有关天气有关大麻桔秆水 分吸附等温线的麻茎的信息是在一个气候室測定，并对桔秆物料 水分的变化是改变湿度下测量。在此基础上，可用的收获时间几 年估计算法。结果表明，显着的收获时间可能在二月和三月了。%The objective of the project was the evaluation of potential possibilities of hemp harvest in the winter for Germany, considered its average climate conditions. Prerequisite for a harvest is that hemp straw achieves low moisture content suitable for storage. For this purpose, hemp stalks were sampled regularly from a hemp field in Potsdam (Germany) between January 2010 and March 2011 to determine their dry matter (DM) content. By the end of February, the hemp stalks achieved a dry matter content of 90%. To obtain information about the weather-related hemp straw moisture sorption isotherms of hemp stalks were determined in a climate chamber, and the change of material moisture of the stalks was measured under changing humidity levels. Based on the findings, an algorithm for estimating available harvesting times for several years was developed. Results show that significant harvesting times may be achieved in the months of February and March.
