| 主要针对我国东北冷凉风沙区在玉米播种时,难以实现原垄免耕播种的问题,提出了大垄双行玉米错茬免耕垄作播种的作业思路,大垄双行技术是指将传统的一垄一行改为一垄双行,垄台宽度约为传统垄台的3倍,目前设计为700 mm;建立了相应的试验田。试验表明:该项技术能够在田间大量玉米根茬直立覆盖情况下,在大垄上实现两行玉米错茬播种,保持垄形,作业质量满足农艺要求。与传统播种方式相比,具有提高地温、降低作业成本、提高产量等优点,可以提高地温约1℃,降低机械作业成本350元/hm2,提高产量14.42%,是保护性耕作技术在东北冷凉风沙区推广应用的一种较理想的模式。 |

| To solve the problem of hard to seed corn in the former ridge without tilling in the northeast of China where the temperature is low and it always blows with lots of sands,the mode of avoiding rootstalks by planting two rows in one big ridge is brought up in this paper."One big ridge,two rows" is a technology that builds on the older "one ridge,one row" method of planting.The width of ridge top is 700mm,which is 3 times as the width of the conventional ridge.The field tests showed that this technology of no-till planter can successfully avoid corn rootstalks and steadily plant corn in the field with many stand-up corn rootstalks.The seeding quality meets the agronomic requirements.Compared with the conventional planting mode,this technology can raise soil temperature by about 1℃,reduce cost of planting by 350 yuan per hectare and increase yield by 14.2%.It is a perfect planting mode for conservation tillage in the northeast of China. |
