山东省多数地区秋季花生收获后,地块闲置,地表裸露,直到翌年春季再种植花生。常年连做,导致养分失衡,有机质降低,重茬病害频发,减产甚至绝产现象时有发生;同时,秋冬季直到翌年春季地表长时间缺少覆盖物,一旦遇大风,尘土飞扬,既污染环境,又不利于水土保持。为改变这种用地局面,提倡在秋季花生收获后,及时播种以毛叶苕子为主的绿肥作物,春季进行耕翻压青或作为饲料利 After harvesting peanuts in most areas of Shandong Province, the plot was left unused and the ground bare until peanuts were replanted the following spring. Perennial even, resulting in nutrient imbalance, reduce organic matter, frequent cropping diseases, crop production and even abortion have occurred from time to time; the same time, autumn and winter until the spring of next year the lack of surface cover a long time, in case of gale, dusty, pollute the environment, Not conducive to soil and water conservation.
