乳浆大戟(Euphorbia esula)是一种侵扰草场或荒地的多年生有毒杂草,它分布于美国北部大平原。本文的研究目的是在最适的生长条件下,测定它产生的潜在能量。在施肥和灌溉后,分三次收割,测量计算油、碳氢化物和干物质的所有数据,并把乳浆大戟作为一种燃料进行测量、分析它潜在的热能。并测定12个品系(Strains)的碳氢化物含量,以研究其遗传变异特性。由于增加施肥量,干物质的产量比未经施肥的多一倍,但其中油和碳氢化物含量的百分比没受影响。在干物质中,油和碳氢化物平均值,分别为6.8％和0.6％。在七月中旬的收获期得到的植物生长量(Biomass)、蛋白质和碳氢化物的含量最多。在后期生长中,油的含量不断提高。全部蛋白质产量平均为12％。整株植物的全部生物量的热量值是每克4407卡,而油的热量值为每克10,019卡。乳浆大戟干草每年产生的能量比小麦杆产生的能量多四倍。建议乳浆大戟植株的全部生物量作为当地的燃料作物,直接用于家庭取暖。 Euphorbia esula is a perennial toxic weed that intrudes on pastures or wastelands and is found in the northern Great Plains of the United States. The purpose of this study is to determine the potential energy it produces under optimal growth conditions. After fertilization and irrigation, all three harvests of oil, hydrocarbons and dry matter were measured and measured. Euphorbia miltiorrhizae was measured as a fuel and the potential heat energy was analyzed. The hydrocarbon content of 12 strains (Strains) was determined to study their genetic variation. As a result of increasing the amount of fertilizer applied, the dry matter yield was twice as high as that without fertilizer, but the percentage of oil and hydrocarbon content was not affected. In dry matter, the average values ​​of oil and hydrocarbon are 6.8% and 0.6%, respectively. The plant biomass (Biomass) obtained during the harvest period in mid-July contained the highest amounts of protein and carbohydrate. In later growth, oil content continues to increase. The average protein yield is 12% on average. Whole plant biomass has a caloric value of 4407 calories per gram, while oil has a caloric value of 10,019 calories per gram. Whey Euphorbia hay produces more than four times more energy per year than wheat straw. It is recommended that the total biomass of the Euphorbia miltiorrhiza plant be used as a local fuel crop for direct household heating.
