我区从1974年开始种植“门源”小油菜,头三年基本上采取了油菜玉米沟沟套和隔沟套种。实践证明,这种种植形式对玉米的铲趟和追肥作业影响很大,同时油菜的株数少,上下两茬夺高产均很困难。今年全区42,771亩油菜,有26,000多亩改为清种,实行油油复种(下茬复种油用向日葵或早熟大豆)。几年的栽培实践,使我们感到油菜清种有很多好处:第一,便于机械化作业;第二,便于旱灌;第三,能实现一茬变两茬,两茬双高产。
My district from 1974 planted “door source” small rape, the first three years basically took rape corn ditch ditch and ditch interplanting. Practice has proved that this form of cultivation of corn shovel trip and top dressing operations have a great impact, at the same time the number of rapeseed, both upper and lower stubble to catch high yield are very difficult. This year 42,771 mu of rapeseed area, more than 26,000 acres to change species, the implementation of oil seed multiplication (the next crop of double crop oil with sunflower or precocious soybeans). Several years of cultivation practices make us feel that there are many benefits to rapeseed cultivation: first, to facilitate mechanized operations; second, to facilitate drought irrigation; third, to achieve double cropping of stubble and double crop yielding.
