不同营养液配方对工业大麻幼苗生长的影响

工业大麻作为一种重要的经济作物在世界上被广泛种植,在纺织、油用、建材、保健和医药方面具有较高的利用价值。水培工厂化生产是工业大麻产业发展的一个趋势,但关于适合工业大麻生长的专用水培营养液配方及浓度尚未报道。为获得适合工业大麻生长的专用水培营养液配方,利用标准霍格兰营养液(1H)和根据工业大麻需肥规律自主设计的不同浓度梯度营养液配方(1Z、1/2Z、1/4Z和1/8Z),研究了不同营养液配方对工业大麻幼苗生长形态及生物量的影响。结果表明:利用1Z和1H营养液培养工业大麻,其幼苗的生长发育无显著性差异;与1H相比,1/4Z显著提高了工业大麻幼苗功能叶的叶面积(约为1350 mm~2)和单株生物量(1.99 g),分别为1H培养条件下的5.8倍和2.2倍;1/8Z促进了工业大麻幼苗株高、根长和生根数的增长。综合考虑,1/4Z和1/8Z为该试验中工业大麻幼苗水培较适宜的营养液配方,研究结果为工业大麻水培专用营养液配方的研制提供参考,为实现工业大麻水培工厂化生产提供理论依据。

Weed control in sunn hemp and its ability to suppress weed growth

Sunn hemp is a tropical, herbaceous annual legume that has potential as a cover crop during the summer in temperate climates. Due to the recent increased interest in sunn hemp breeding and seed production for temperate climates, there is a need for weed control in sunn hemp production. No herbicide product currently on the market specifically identifies sunn hemp as a tolerant crop. The aims of this research were 1) to evaluate herbicides with the intent of identifying a herbicide program that can assure near weed free sunn hemp intended for seed harvest and 2) to demonstrate and quantify sunn hemp-weed suppression. Pre-emergence applied treatments consisted of pendimethalin alone, imazethapyr alone, and pendimethalin plus imazethapyr. Pendimethalin alone provided consistent effective weed control and maximum sunn hemp biomass, but when yellow nutsedge was present, imazethapyr was required for effective control and greater sunn hemp biomass. The combination of pendimethalin and imazethapyr was detrimental to sunn hemp biomass yield. Results also established that sunn hemp is tolerant of 2,4-DB applied post-emergence, but was not necessary for weed control in these studies because of the lack of broadleaf weed pressure. In a separate study with variable sunn hemp densities, weed biomass reductions of ≥50% were obtained with sunn hemp densities of only 20 to 50 plants m⁻². This degree of weed suppression obtained from relatively modest sunn hemp densities is likely indicative of the ability of sunn hemp to grow faster and taller than other plants.     

Italy-grown hemp: yield,composition and cannabinoid content

Following the program of the Italian Administration for the reintroduction of hemp cultivation in Italy, many problems arose concerning the agricultural aspects, the processing of the raw material (usually hemp roundbales) and the presence of cannabinoids in the hemp crop. This study was set in order to answer some of these questions. In 1998, eight hemp varieties (three dioecious Italian genotypes and five monoecious French genotypes) were grown in Ferrara province, Italy by the AASM. The hemp was harvested at two different periods. The stems were analysed and dry-mechanically treated at the Centro Tecnico Industriale of IPZS in Roma and the cannabinoid content analysis was performed at the ISCI, Bologna. No significant difference was found for the biomass production neither between the eight varieties nor between the two different harvesting periods. The dry-mechanical treatment is very effective in removing the relatively low-value fractions of the crop (like the top sections of the stems). The eight hemp varieties perform differently at the dry mechanical separation treatment and give different percentages of bast, core and dust. Cannabinoids do not accumulate in the dust fraction thus showing that the dry-mechanical treatment does not increase the concentration of harmful substances in by-products.     

The environmental impacts of the production of hemp and flax textile yarn

This study aimed to quantify major environmental impacts associated with the production of hemp yarn using Life Cycle Analysis (LCA). A reference scenario of traditional hemp warm water retting was compared to: (1) bio-retting, i.e. hemp green scutching followed by water retting, (2) babyhemp, based on stand retting of pre-mature hemp, (3) dew retting of flax. Overall, neither of the alternative scenarios was unambiguously better than the reference. The impacts of the hemp reference scenario and the flax scenario were similar, except for pesticide use (higher for flax) and water use during processing (higher for hemp). Bio-retting had higher impacts than the reference scenario for climate change and energy use, due to higher energy input in fibre processing. Babyhemp had higher impacts than the reference scenario for eutrophication, land occupation and pesticide use. A reduction of the environmental impacts of hemp yarn should give priority to reduction of energy use in the fibre processing and yarn production stages and to reduction of eutrophication in the crop production phase.
