自七十年代中期起,随着耕作制度的调整结合栽培技术的不断改革,在我市北部丘陵地区形成一种新的栽培制度。即“油(菜)—瓜(打瓜或西瓜)—稻”或“油—瓜—豆(黄豆)”。其特点是:两旱一水,间种配套,一年三熟,粮油(或经济作物)轮作,用养结合,增产增收。整套耕作栽培技术或复种轮作形式是:油菜—籽瓜—水稻或油菜—籽瓜—黄豆(套种)。这种形式把作物布局、耕作制度、轮作方式、栽培技术有机地结合在一起,实践证明,是一项促粮油生产和经济作物发展的有效途径,目前已成为我地区主要种植结构。
Since the mid-1970s, with the adjustment of farming system combined with the continuous reform of cultivation techniques, a new cultivation system has been formed in the hilly areas in the northern part of our city. Namely “oil (vegetables) - melon (melon or watermelon) - rice” or “oil - melon - beans (soybeans).” Its features are: two dry and one water, between the supporting facilities, three crops a year, grain and oil (or cash crops) rotation, with raising, increase income. The whole set of tillage or multiple crop rotation is: Rape - Watermelon - Rice or Rape - Watermelon - Soybean (interplanting). This form organically combines crop layout, cropping system, crop rotation and planting techniques. Practice has proved that it is an effective way to promote grain and oil production and cash crop development and has now become the main planting structure in our region.
