摘要:

利用受环境因子胁迫不利于生产粮食的农田种植能源作物,不仅能保证农业的可持续发展,还可为生产生物质能源提供原料,缓解能源危机。由于能源作物中的糖分是生产生物质燃料乙醇的基础,所以本文综述了水分、盐碱、温度、NPK(氮、磷、钾)养分、种植密度、植物激素和重金属等因子对能源作物糖分积累的影响,发现干旱、盐碱、适宜低温等非生物胁迫及适量的施用NPK肥、稀土元素或ABA(脱落酸)有利于促进作物糖分的积累,表明合适的非生物胁迫及适量的补施肥料或叶面微肥可极大促进乙醇产量,这将为更好地利用受环境胁迫不适宜生产粮食的农田种植能源作物提供理论依据和技术支撑。

Abstract:

Using agricultural field, which is not suitable for food crop production under the stress of unfavorable environmental factors, to cultivate energy crops can not only ensure sustainable agricultural development, but also provide feedstock for biofuels production, and then alleviate energy crisis. Because sugar is the base for producing biofuel ethanol, this study reviewed the effects of water, salinity, temperature, NPK (nitrogen, phosphorus, potassium) nutrients, planting density, plant hormones and heavy metals, etc. on the accumulation of sugar in energy crops. It is found that drought, salinity-alkalinity or slight low temperature, and proper application of NPK fertilizer, rare earth elements or ABA (abscisic acid) are beneficial to promote sugar accumulation in crops, indicating that appropriate abiotic stresses and supplementation of fertilizer or foliar application of micro-fertilizer could substantially facilitate ethanol production. The study could provide theoretical basis and technical support for better use of farmland, which is not suitable for food production as a result of environmental stress, to cultivate energy crops.

Key words: energy crops, biomass energy, crops with high sugar content, sucrose, stress, ethanol, environmental factors
