1990年,辽中县为了搞好辽河滩地开发水浇麦,引进了具有国内先进水平的半固定轻移喷灌设备,在六间房乡长岗子村350亩河滩地上,进行了春小麦喷灌试验。3月10春翻春耙整地;3月16—18日采用链轨拖拉机牵引的24行小麦播种机实行机播;品种为铁春1号,亩播种量22.5公斤;随种亩施磷酸二铵20公斤、硫酸铵10公斤、尿素5公斤。小麦生育期灌3次水:第一次于4月25—28日灌分蘖水,同时追施硫铵12.5公斤;第二次灌水在5月10—14日,追施硫酸钾10公斤;第三次灌水在6月7—10日。采用2,4-D丁酯药剂灭草一次,用乐果和除虫菊粉防治蚜虫各一次,基本上控制了危害,7月7日开始收获。
In 1990, Liaozhong County introduced a semi-fixed light-weight sprinkling irrigation equipment with advanced domestic level to develop water-irrigated wheat in the Liaohe beach. The spring wheat sprinkler irrigation experiment was carried out on the 350-mu riverbank land in Changgangzi Village, Liufang Township. March 10 spring spring rake site preparation; March 16-18 using the tractor traction 24 rows of wheat sowing machine planting; varieties for the iron spring 1, acres sowing capacity of 22.5 kg; 20 kg, ammonium sulfate 10 kg, urea 5 kg. Wheat growth period of irrigation 3 times the water: the first time in April 25-28 irrigation tillering water at the same time the topdressing ammonium sulfate 12.5 kilograms; the second irrigation on May 10-14 topdressing 10 kilograms of potassium sulfate; Three irrigation in June 7-10. Using 2,4-D butyl pesticide herbicides once, with dimethoate and pyrethrum prevention and treatment of aphids once, basically control the hazards, July 7 began to harvest.
