| 摘 要： | 收获指数和秸秆系数对作物生产研究和秸秆资源评估具有重要意义。本研究主要根据2006—2010年文献的田间实测数据,研究了非禾谷类大田作物在中国大陆主产省份的收获指数和秸秆系数。结果表明:大豆收获指数和秸秆系数全国平均值分别为0.42和1.50,6个省份的收获指数为0.35～0.47,秸秆系数1.13～1.86。马铃薯收获指数和秸秆系数的全国平均值分别为0.59和0.71,甘薯分别为0.69和0.45,木薯分别为0.64和0.50。其中,11个省份的马铃薯、甘薯和木薯等薯类作物收获指数为0.55～0.77、秸秆系数0.30～1.17。棉花皮棉收获指数和秸秆系数全国平均值分别为0.15和2.91,5个省份棉花的皮棉收获指数为0.12～0.18,秸秆系数2.41～4.09。花生的收获指数和秸秆系数全国平均数分别为0.50和1.14,6个省份花生收获指数为0.41～0.54,秸秆系数0.85～1.43。油菜的收获指数和秸秆系数全国平均数分别为0.26和2.87,6个省份油菜收获指数为0.24～0.28,秸秆系数2.57～3.17。向日葵收获指数和秸秆系数全国平均数分别为0.32和2.63,4个省份向日葵收获指数为0....

| Abstract: | Harvest index(HI) and residue factor(RF) are of essentially significance for crop production research and crop residue quantity assessment.HI and RF of non-cereal crops in their main production provinces of China are reviewed according to field data collected from original papers published mainly during 2006-2010.HI of soybean varied between 0.35 and 0.47 whereas RF between 1.13 and1.86 across six provinces,and the average was 0.42 and 1.50,respectively.Tubers including potato,sweet potato,and cassava had H... |
