怀宁县的群众习慣采用兰花草与荞麦、油菜、蘿卜等作物混种的方法,其中尤以与养麦混种的最多,約佔中稻茬兰花草的80%以上。为什么呢?从高河公社谢山大队的调查資料可以看出兰花草与荞麦混种最合理,在“处暑”后十天播种的,亩产鮮草三千四百斤,荞麦亩产也在七十斤左右。采用这种方式,兰花草能够适时播种,荞麦收获又早,不影响兰花草生长,鮮草产量高;又能增产粮食,应大力提倡。与油荣混种,由于兰花草播种要迟些(“秋分”后一天),两者又同时生长,互有一定影响,鮮草产量每亩为二千 Huaining County, the masses habit of using orchids and buckwheat, rapeseed, radish and other crops mixed method, especially with the most mixed wheat, accounting for more than 80% of medium-stubble orchids. Why? From the investigation of the high river commune Xie Mountain Brigade can be seen the most reasonable mixed species of orchids and buckwheat, sowing ten days after the “summer heat”, yielding 3,400 kilograms of fresh grass, buckwheat yield is also seven Ten pounds or so. In this way, orchids can sow in time, buckwheat harvest early, does not affect the growth of orchids, fresh grass yield; but also increase grain production, should be vigorously promoted. Mixed with the oil-wing, as orchids sowing later (“autumn equinox” the day after), both at the same time growth, mutual influence each other, fresh grass yield per thousand acres
