摘要

根据标准 ČSN 46 1100-5,对 2023 年收获的 243 个发芽大麦样品的质量参数进行了评估。2023 年收获的大麦质量的总体特点是:谷物中的氮含量较低,数值范围相对较宽,从 7.8 % 到 13.7 %;2.5 毫米筛以上的筛分率较低,平均为 87.2 %。无法用于麦芽加工的谷物掺杂物含量较低,这一点很有利。遗憾的是,部分大麦受到了降水的影响,降水的形式是收割前的雷暴,但主要是八月前十年的降雨,中断了收割。这场降雨导致大麦受到微生物侵染,并有可能因发芽谷粒的存在而导致发芽率降低或丧失,54% 的样本中发现了隐性发芽。

Quality of malting barley grain in the Czech Republic, crop 2023
The quality parameters of 243 malting barley samples were evaluated according to the standard ČSN 46 1100-5 from the 2023 harvest. The quality of the 2023 harvest can generally be characterised by a lower nitrogen content in the grain with a relatively wide range of values from 7.8 % to 13.7 % and lower values of sieving fractions above the 2.5 mm sieve, which averaged 87.2 %. The lower content of grain admixtures unusable for malting is favourable. Unfortunately, some of the barley was affected by precipitation, which came in the form of thunderstorms prior to harvest, but mainly by the rainfall that fell in the first decade of August and interrupted the harvest. This rainfall led to microbiological infestation of the barley and to the risk of reduced or lost germination due to the presence of sprouted grains, as confirmed by 54 % of the samples in which hidden sprouting was identified.
