摘　　要：为提高低洼地的耕地质量和玉米产量,基于“梨树模式”保护性耕作,提出一种在耕地地表开沟的排水方案。通过在四比空种植模式的“空”行地表挖设排水沟,能够容纳相邻4行垄的秸秆和自然降水,从而实现提高地温和改善作业条件的目标。In order to improve the quality of cultivated land and the yield of maize in low-lying land,a drainage scheme of draining on the surface of cultivated land was proposed based on"pear tree model"conservation tillage.By digging a drainage ditch in the"empty"row surface of the four-ratio-empty planting mode,it can accommodate the straw and natural precipitation of the adjacent four rows of ridges,so as to achieve the goal of raising the ground temperature and improving the working conditions.
