【Abstract】 Four years’ study results showed that the conventional method of planting spring corn in northeast areas of China can not resist spring drought, store rainwater, return straw to the field, therefore it needs more field operations and higher cost. A new tilling method that is called as striped deep loosening of wide narrow row alternative planting can conserve the soil water in spring, protect most seedlings, loosen soil deeply to store soil water and use the rainwater of summer in next spring time. The new method is convenient to return straw to the field. It improves soil texture and reduces field operations and costs on the premise of increasing output. It is also a new tilling method which can accelerate the agricultural sustainable development.更多还原
