张养利是渭南市农业科学研究院高级农艺师，也是"渭麦9号"等旱地小麦品种的培育者。白吉庆告 诉记者，联合社的成员社和成员农户、养殖场，为处理发酵后的粪污流转了大量土地种植小麦。作为该 联合社"科学家精神实践小院"的"首席专家"，张养利带领团队与联合社合作开展新品种引进和试验示 范、新技术推广应用，着力解决当地小麦品质不优、品种抗逆性不强、播种质量不高的问题。今年"渭 麦19号"表现优秀，在旱情严峻的情况下亩产达364公斤，表现出较强的抗旱稳产性。 针对畜禽粪污处理，张养利还邀请了陕西科技大学教授李祥前来指导。"当地搞养殖的人很多，粪 污处理是个大问题。以前我们利用粪污发酵产生沼气时，采用堆积发酵法，要么需要大量人力，要么需 要购买昂贵的翻抛机，发酵时往往臭气熏天。"白吉庆告诉记者，"李祥指导我们利用菌剂快速发酵，从 以前的夏季发酵需要2至3个月缩短为现在的10来天，不但省人工，还没有臭味，降低了成本。目前，该 技术在县上的4家养殖场试验示范，正处于扩大试验阶段。" 9月12日，在西安市鄠邑区的一片玉米田里，户县金辉种植专业合作社理事长张辉看着眼前集中连 片的玉米地，脸上喜气洋洋。"8月中旬，我们开展了最后一次' ...

Core Viewpoint - The article highlights the efforts of Weinan, a key grain production area in Shaanxi, to maintain stable summer grain production despite severe high-temperature weather, through the integration of various agricultural practices and technologies [1][4]. Group 1: Technological Support - The introduction of the drought-resistant wheat variety "Weimai 19" by Weinan Agricultural Science Research Institute, which has shown promising yield results [2]. - The promotion of the "seed industry revitalization" initiative, focusing on drought-resistant wheat varieties to ensure stable production [2][3]. - The implementation of a comprehensive technical service program involving over 1,100 agricultural technicians to enhance planting quality and promote high-yield techniques [3]. Group 2: Production Stability - Weinan's summer grain production remains stable due to effective measures such as irrigation, with a total wheat area of 4.407 million acres and 3.17 million acres of irrigated land [4]. - The transformation of saline-alkali land into productive fields, achieving wheat yields exceeding 700 kg per acre in previously barren areas [4]. Group 3: Mechanization and Efficiency - The use of advanced agricultural machinery and technology, including over 90,000 units of various farming equipment, leading to a mechanization rate of 99.5% for wheat harvesting [6]. - The peak daily wheat harvesting reached 527,000 acres during the "Three Summer" period, showcasing the efficiency of mechanized farming [6]. Group 4: Systematic Innovations - The integration of grain planting area and production into rural revitalization performance assessments, with a comprehensive action plan for enhancing grain yield by 2025 [7]. - The establishment of numerous agricultural social service organizations and cooperatives, facilitating full-service management of grain production [8].
