冬小麦全生育期地膜覆盖穴播栽培技术,是甘肃省农科院李守谦研究员创立的节水抗旱高产栽培新技术(简称地膜小麦).农业部把这项新技术列为1997年全国推广的十大重点技术之一.我区于1997年秋种开始引进该技术及穴播机械.在宁海镇峡河村和文化农场安排了试验示范,取得了显著的抗旱增产效果.全区推广面积达2万余亩.平均亩产543.5kg,比对照442.7kg,增产100.8kg, 增22.8%.现对增产机理及栽培技术简述如下:
Winter wheat growing period of film-covered acreage cultivation techniques, is Gansu Academy of Agricultural Sciences researcher Li Shouqian water-saving drought-resistant high-yielding cultivation of new technologies (referred to as plastic film wheat.) Ministry of Agriculture listed the new technology as the 1997 national top ten priorities One of the technologies.Our district started to introduce this technology and hole-punching machine in the fall of 1997.To experiment and demonstration were arranged in Ningxia Zhenxiahecun and Cultural Farm and achieved significant drought-resistant and yield-increasing effect.The area of promotion reached more than 20,000 mu.The average Mu yield 543.5kg, 442.7kg more than the control, increase 100.8kg, increase 22.8% .About yield mechanism and cultivation techniques are as follows:
