New Polish Oilseed Hemp Cultivar Henola – Cultivation, Properties and Utilization for Bioethanol Production

ABSTRACT

In recent years, the cultivation of hemp for seed has been gaining significant importance. Intensive breeding work resulted in the registration of a new oilseed hemp variety with high seed yield called Henola. Hemp of this variety is characterized by a vegetation period shorter by about a month, almost twice shorter technical length of plants and significantly larger inflorescences than fibrous hemp of the standard variety (Białobrzeskie).

This work analyzes the efficiency of the second-generation bioethanol production process derived from the processing of waste biomass remaining after deseeding the panicles of the Henola variety. The research material consisted of biomass samples obtained from three variants of the fertilization experiment carried out at the IWNiRZ Experimental Farm in Stary Sielec in temperate climate conditions. In order to find out about the properties of the raw material, the chemical composition of hemp straw was tested and the bioethanol yield per 1 ha of crops was determined.

Henola oilseed hemp straw yield was the lowest (10.6 Mg∙ha⁻¹) in the case of the control and the highest (11.3 Mg∙ha⁻¹) with the use of complex phosphorus, potassium and nitrogen fertilization. The average content of cellulose in the analyzed samples was 35.5%, holocellulose 68%, and hemicellulose 32%. The amount of lignin, in turn, was independent of the type of fertilization. The lowest bioethanol content, in the amount 7.11 g∙L⁻¹, was found in case of hemp fertilized with nitrogen, phosphorus and potassium, and the highest content amounting to 9.93 g∙L⁻¹ – for hemp fertilized with phosphorus and potassium, for which the ethanol yield, converted into straw yield was 2.7 m³∙ha⁻¹.

The conducted research covers both the identification of pro-environmental solutions in the economy for the management of waste biomass and the implementation of the RED II Directive on the promotion of energy from renewable sources.

摘要

近年来，大麻种子的种植越来越受到重视. 密集的育种工作导致了一个新的油籽大麻品种的登记与高产种子称为Henola. 这种大麻的特点是植被期缩短了约一个月，几乎两倍短的植物技术长度和明显更大的花序比纤维大麻的标准品种（比娅）1ha 奥布热斯基）.

本研究分析了第二代生物乙醇生产工艺的效率，该工艺来源于处理去除苯酚品种圆锥花序后剩余的废弃生物质. 研究材料包括从斯达里希莱克IWNiRZ实验农场在温带气候条件下进行的施肥试验的三种变体中获得的生物量样品. 为了了解原料的性质，对大麻秸秆的化学成分进行了测试，并测定了每公顷作物的生物乙醇产量.

油麻秸秆产量最低（10.6mg）∙ha-1），对照组最高（11.3mg）∙ha-1）配合施用磷、钾、氮复合肥. 分析样品中纤维素的平均含量为35.5%，全纤维素为68%，半纤维素为32%。木质素的含量与施肥方式无关. 最低生物乙醇含量，为7.11 g∙施氮、磷、钾的大麻中L-1含量最高，达9.93g∙L-1——对于施用磷和钾的大麻，乙醇产量转化为秸秆产量为2.7 m3∙ha-1型.

所进行的研究既包括确定废物生物量管理经济中的有利环境解决方案，也包括实施关于促进可再生能源能源的RED II指令.
