兖州市从1998年开始实施“万亩山药高产高效开发”富民工程。两年来,我们重点搞了山药与其他作物间作套种模式的试验研究,经过对多种模式的探讨、研究,筛选出山药与番茄、花椰菜(菜花)、白菜(油菜)、菠菜间作套种,一年五种五收,亩收入超万元的种植模式。该种植模式既充分显示了高、矮秧间作套种通风透光好,病害少,产量高的优势,又可化解单一种植的市场风险,综合效益高。现将该种植模式介绍如下: 一、菠菜 10月底至11月初,播种日本全能菠菜品种,翌年3月中旬全部收获。亩产量3000kg左右,可收入900元左右。二、山药 4月初播种山药,选用“牛腿米山药”高产优质品种。种植行距2 m,株距14 cm,亩 Yanzhou City since 1998 to implement “mu of yam high yield and efficient development ” enriching people project. In the past two years, we focused on experimental research on intercropping patterns between yam and other crops. After a series of studies and studies on various models, we selected yam and tomato, cauliflower (cauliflower), cabbage (rape) and spinach intercropping for one year Five kinds of income, acres of super-million yuan of planting mode of income. The planting pattern not only fully shows the advantages of high and low seedling intercropping with good ventilation and light, less disease and high yield, but also can ease the market risk of single planting with high comprehensive benefits. Now the planting patterns are described as follows: First, spinach end of October to early November, sowing Japan's all-around spinach varieties, all in the middle of March the following year harvest. About 3,000 kg of mu output, income of 900 yuan. Second, yam sow planting yam early April, use “cow leg rice ” high yield and high quality varieties. Planting spacing 2 m, spacing 14 cm, mu
