Italy needs to develop renewable energy sources and agriculture offers many opportunities: biomass, vegetable residues for livestock breeding, food industry waste, organic waste, solid biofuels, biogas, and biofuels, will be the new renewable energy sources. Researches for promoting sustainable development, including chemistry field are increasing interest in the exploitation of vegetal biomass, in particular waste as a raw material for production of bio-products and biofuels. Not always, however, the use of waste materials such as biomass is the most appropriate, or in any case, the one with less energy expenditure. As ever more evident, in fact, the construction sector is approaching the possibility of using these materials for other purposes, combining the demands of saving natural resources, the need for energy efficiency in buildings and production processes.展开更多

文摘为研究精异丙甲草胺在大麻田杂草化学防控中的使用效果,进行了960 g/L精异丙甲草胺EC适宜剂量筛选田间试验,并进行了试验示范。结果表明,960 g/L精异丙甲草胺EC 900 m L/hm2处理的药后50 d后株防效和鲜质量防效分别为81.68%、81.33%,麻籽增产率为45%,为最优施用剂量;在技术示范中,960 g/L精异丙甲草胺EC施用量为900 m L/hm2的处理大麻产量有所增加,但与对照药剂相比差异不显著。用该药剂的适宜剂量来防除大麻田杂草具有可行性。
