[目的]研究粉垄整地与传统整地种植作物生长及产量的差异性。[方法]采用专用型机械将土壤垂直旋磨粉碎并自然悬浮成垄的粉垄整地与拖拉机整地、畜力整地和人力整地3种方式比较,以玉米、花生为供试作物品种,各个处理全期均不施肥。测定玉米、花生前期的根系长度和数量,后期功能叶片的光合特性及产量。[结果]与拖拉机整地、畜力整地和人力整地相比,粉垄整地种植的玉米、花生前期的根系长度增加18%以上,数量增加15%以上,后期功能叶片的净光合速率提高10%以上,产量增加8%以上。[结论]粉垄整地方式种植的作物比传统整地的根系发达,光合效率提高,产量增加。
[Objective] The research aimed to study the difference of cropland growth and yield between polder ridge land preparation and traditional land preparation. [Method] Compared with the three methods of soil preparation, such as vertical furrowing of soil by soil crushing and natural suspension of ridge and furrow for ridge land preparation, tractor site preparation and animal land preparation and manpower land preparation, the maize and peanut were used as tested crop varieties. No fertilization. The length and number of roots and the photosynthetic characteristics and yield of functional leaves at the early stage of maize and peanut were determined. [Result] Compared with tractor site preparation, animal husbandry and land preparation, the length of root system increased by more than 18% and the number of maize increased by more than 15% and the net photosynthetic rate of functional leaves increased by 10% Output increased by 8% or more. [Conclusion] The crops planted by the ridge land consolidation system developed better than the traditional land preparation, photosynthetic efficiency and yield increased.
