对东北地区春玉米耐老化膜常年覆盖种植及宽窄行留高茬交替休闲种植方式的研究结果表明,与传统种植方式相比,耐老化膜常年覆盖种植和宽窄行留高茬交替休闲种植在产量、经济效益和生态效应上均表现出较好的态势。耐老化膜常年覆盖种植的增产优势明显,与均匀垄传统种植相比,产量增加15.56%,并且降低了农业生产成本,经济效益显著增加,播种出苗阶段及苗期风蚀量降低562%和303%,田间养分损耗量明显下降。耐老化膜常年覆盖种植方式在东北地区是具有推广前景的保护性耕作技术模式。
The results showed that the perennial planting of spring corn anti-aging film in northeast China and the alternate leisure planting mode of wide and narrow row standing high stubble showed that compared with the traditional planting mode, , Both economic and ecological effects have shown a good trend. Compared with the conventional planting with uniform ridge, the yield increased by 15.56%, the agricultural production cost was reduced, the economic benefit increased significantly, the amount of wind erosion decreased by 562% and 303% respectively in the seedling stage and seedling stage, , The amount of nutrient loss in the field decreased significantly. Anti-aging film perennial planting methods in Northeast China is a promotion of conservation tillage technology model.
