我县常年稻茬麦面积50万亩以上。历史上,由于耕作栽培方式不当,难以发挥肥水优势,变成“高肥水低产田”。进入80年代,逐步摸索了一套以“三改一化”为中心的丰产栽培技术,使稻茬麦单产不断提高,由低产拖腿田,变为高产龙头田。今年5月,通过由省农林厅等专家组成的“丰收计划”联合验收小组验收,平均单产已达333公斤,较全县平均单产增21.5%。具体措施介绍如下。一、改常规耕翻播种为少、免耕播种过去往往是烂耕烂种,播期推
My county perennial rice crop area of 500000 acres or more. Historically, due to improper cultivation and cultivation methods, it is difficult to play the advantages of fertilizer and water, into “high fertility low yield field ”. Into the 80’s, and gradually explored a set of “three changes and one ” as the center of high yield cultivation techniques, so that rice crop continuous improvement of wheat, from low-yield drag legs, into high-yield leading fields. In May this year, through the “harvest plan” by the Provincial Department of Agriculture and Forestry and other experts composed of acceptance inspection team, the average yield has reached 333 kg, compared with the county average yield increased 21.5%. Specific measures are described below. First, the conventional farming tillage sowing less, no-tillage seeding often rotten farming rotten, sowing push
