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.

Through the research on ageing-resistant film perennial mulch crop and alternative fallow high stub-ble about wide ahemative narrow row, the result proves that this measure shows better trend in output, economic profit and ecological effect, compared with the traditional one.The former is prominent in the yield-increasing advantage and the output increases by 15.56%, compared with the traditional measure by means of the uniform ridge.Moreover, it reduces the cost of the agricultural production, and increases the economic profit remarkably, the amount of wind erosion decreases562% and 303% in seedling date, the amount of soil nutrient wasting decline significantly.This measure is a kind of conservation tillage technical mode which is valuable for extension and prospect.
