Abstract

The invention relates to a regulation and control method for water-fertilizer integral water-saving and fertilizer-saving efficient culture of winter wheat, which belongs to the technical field of water-fertilizer irrigation. The method is characterized by being carried out through controlling water-fertilizer integration, and comprises the steps of applying base fertilizer before soil preparation, then sowing with enough soil moisture, pressing after sowing, and irrigating once during an elongation stage after reviving of the winter wheat, a booting stage and a filling stage respectively, and carrying out topdressing during irrigation through dissolving fertilizer into water for irrigation, wherein the irrigation time in the elongation stage, the booting stage and the filling stage is the time when the relative water content of soil with the depth of 0 to 60 cm is less than or equal to 55 percent. The regulation and control method provided by the invention is simple and easy to operate; by the establishment of the regulation and control method, the grasp and application on a corn water-saving and fertilizer-saving production technology by farmers in a droughty and water-lack area can be greatly facilitated, in addition, the farmers can take corresponding methods in time when drought occurs and in a fertilizer-needing key period, so that loss caused by wheat drought is reduced, water and fertilizer utilization efficiency is improved, and efficiency and yield increase is realized.

Description

technical field [0001] The invention belongs to the technical field of water and fertilizer irrigation, and relates to the water-saving planting technology of winter wheat moisture content measurement, irrigation, top dressing, and water-saving planting, and specifically relates to a water-fertilizer integrated water-saving and fertilizer-saving high-efficiency cultivation control method for winter wheat. The control method of the present invention is simple and easy to operate. After the control method of the present invention The establishment will greatly facilitate farmers in arid and water-scarce areas to master and apply wheat water-saving and fertilizer-saving production technologies, and it will also facilitate farmers to take timely countermeasures when droughts occur and critical periods of fertilizer demand to reduce losses caused by wheat droughts. Improve water and fertilizer use efficiency and achieve efficiency and yield increase. Background technique [0002]...
