In order to optimize irrigation method for alfalfa growth in saline-alkali soil in the Yellow River Delta region, a field plot experiment was conducted. In the experiment, three irrigation methods such as natural rainfall, drip irrigation and flood irrigation are applied. The effects of these irrigation methods on plant height, population, yield and water-salt dynamics in the saline-alkali soil are observed. The experimental results show that the plant height and yield of alfalfa are all increased in flood and drip irrigations in comparison with natural rainfall. There is not significant difference in the plant height and yield of alfalfa from flood irrigation to drip irrigation with 60% water saving, suggesting drip irrigation is one water saving irrigation method which is worthy of recommendation to alfalfa cultivation. In flood irrigation, the water content in 0-60 cm thick soil layer is mainly affected, in drip irrigation, however, the water content in 0-20 cm layer is changed significantly. The salt content in 0-60 cm soil layer is affected greatly in flood irrigation in comparison with 0-20 cm soil layer in drip irrigation. The PH and EC values in 0-60 cm soil layer vary in flood irrigation, however, these values seem to show a uniform variation across the whole layer in drip irrigation. © 2017, Editorial Department of Journal of Drainage and Irrigation Machinery Engineering.

In order to study and analyze the comprehensive benefits of pollution control engineering of livestock and poultry breeding, the comprehensive evaluation index system was protocoled according to the investigation and analysis of present situation in China. At the same time, 8 typical engineerings were used as examples. The analytical hierarchy process(AHP) and grey relational grade(GRG) analysis were used as evaluation methodology. The assessment results showed that larger scale and comprehensive engineering can achieve higher comprehensive benefits than others. Only biogas engineering used to control livestock pollution couldn't achieve ideal comprehensive benefits, because the economics of biogas engineering is very poor under the current conditions in China.
