晋北地区玉米/蔬菜不同套作模式效益分析

[目的]研究旨在分析晋北地区推广的三种“玉米/蔬菜”套作模式在市场行情因素影响下的种植效益,为当地农户在套作模式选择上提供理论基础。[方法]通过三年试验及市场行情跟踪,以产量和效益为依据,对三种套作模式所承担的市场风险做出总结。[结果]“玉米/甘蓝”是试验中毛收益波动最大的模式,市场风险极大；“玉米/高菜”是毛收益最稳定的模式；在劳动力充足的前提下,“玉米/芸豆”是毛收益较高的模式。[结论]在实际生产中,农户可根据自身抵抗市场风险的能力及对市场行情的预判断,选择适宜的套作模式进行种植,以达到增收的目标。

Maize/Vegetable Relay Intercropping Modes in Northern Shanxi: Efficiency Analysis

[Objective] The study was designed to analyze the three kinds of maize/vegetable relay intercropping mode that were marketed in North Shanxi Province, and to provide the theory base for local farmers when they make choice on the three relay intercropping mode. [Method] The market risks assume was summarized according to the production and efficiency of three relay intercropping mode by three years" test and market trend. [Result]The gross yield of maize/ Brassica oleracea L. shows the greatest volatility in this study, so the market risk is great. The gross yield of maize/Brassica juncea var. is most stable. On the premise of sufficient labor force, corn/ Phaseolus vulgaris is the mode with high gross profit. [Conclusion] In the actual production, farmers can choose the appropriate relay intercropping mode in order to achieve the goal of increasing revenue according to their ability to resist market risk and the prejudgment of market conditions.
