夏休小麦(F)-冬小麦（Triticum aestivum L.）的多样化(2)草料代休制能提高黄土高原区牧草产量和降水利用效率。然而，其对蛋白质生产力的影响尚不清楚，也不清楚蛋白质生产力的提高是否会增加土壤水分的提取和经济投入。通过为期3年（2011-2013）的田间试验，研究了草料油菜轮作对夏休系统生产力、经济效益和可持续性的影响。（右）和野豌豆（Vicia唾液L.）(V)。结果表明，饲草轮作对后续冬小麦土壤水分贮量没有影响。与FWFW轮作相比，草料作物轮作使粗蛋白质产量的降水利用效率（PUECP）和粗蛋白质产量的系统水分利用效率（WUECP）分别提高了20%和28%。RWRW轮作系统的粗蛋白质产量（CPyield）最高，FWRW次之，RWVW轮作系统的CPyield分别比FWFW系统高51%、21%和36% （P < 0.05）。相比之下，FWFW轮作系统的净收入最高（us $2,005 ha(-1)），分别比FWVW、RWVW、FWRW和RWRW系统高27%、20%、34%和29% （P < 0.05）。因此，考虑到盈利能力和可持续性，建议当地农民采用FWFW和RWRW交替轮作系统。
Diversifying the summer fallow (F)-winter wheat (Triticum aestivum L.) (W) cropping system by replacing summer fallow with forage crops could increase forage yield and precipitation use efficiency in the Loess Plateau region of China. However, its influence on protein productivity is unclear and it is unknown whether improvement in protein productivity will increase soil water extraction and economic input. A three-year (2011-2013) field experiment was conducted to investigate the rotational effect on system productivity, economic benefit, and sustainability when summer fallow was replaced with forage rape (Brassica napes L.) (R) and common vetch (Vicia saliva L.) (V). Results showed that the rotation system with forage crops did not alter soil water storage of subsequent winter wheat. Compared with the FWFW rotation system, the rotation system with forage crops improved precipitation use efficiency of crude protein yield (PUECP) and system water use efficiency of crude protein yield (WUECP) by 20 and 28% respectively. The greatest crude protein productivity (CPyield) was achieved with the RWRW rotation system, followed by the FWRW and RWVW systems, and CPyield with these systems was 51, 21, and 36% greater than that with the FWFW system, respectively (P < 0.05). In contrast, net income in the FWFW rotation system had the greatest value (U.S. $2,005 ha(-1)), 27, 20, 34, and 29% greater than that in the FWVW, RWVW, FWRW, and RWRW systems, respectively (P < 0.05). Consequently, the alternate rotation system of FWFW and RWRW is recommended for local farmers when considering both profitability and sustainability.
