滴灌本来是以色列率先使用的农业节水技术，新疆较早开始引入，一开始是用在经济作物上，现在大田 作物也在使用，这得益于我国强大的制造能力，让滴灌成本大幅下降，普通农田使用起来也有了性价 比。 滴灌需要地下水源配合，还有些区域为丘陵地带，干旱且没有灌溉条件，就需要种植耐旱农作物，当地 培育出耐旱小麦品种，其根系可达3米以上，远超普通小麦。 在新疆塔克拉玛干沙漠边缘的沙化盐碱地，今年农户种植的冬小麦亩产达到700公斤。这种地块有机质 含量低，风蚀沙化严重，保水保肥能力差。技术人员选择抗旱、耐盐碱的小麦新品种，然后通过播种期 缩行增密、全程水肥一体化管理，实现了小麦高产。 近年来种田大户日渐增多，种田大户更愿意采用节省劳动力的机械化耕作，增加投资采用新技术，听取 农业技术人员的建议，采取积极措施消弭天灾影响。粮食稳产增产离不开我国庞大的农业技术服务群体 的帮助，以及我国生产制造能力的提升，这些均为农业发展提供了比较优质的环境。 夏收已接近尾声，今年有望再迎一个丰收年。丰产的背后，离不开农业技术的进步，包括灌溉技术、育 种技术、农业专业技术服务能力的提升。 传统农业收成很大程度上靠天吃饭。近些年，国内一些地方干旱天气不断 ...

今年"三夏"，在希望的田野上，一幅丰收画卷徐徐展开。随着安徽、河南小麦机收相继结束，山东麦收进度过七成，陕西麦收进度过八成，全国冬小麦收获 已进入收尾阶段。 今年"三夏"有什么新特点？ 记者将小麦主产区的农机投入数量、机收轨迹、气象数据以及农田灌溉数据打包，形成了"三夏"AI智能体。 当问及"今年小麦主产区气候多变，如何保障产量？"时，智能体提炼出三个关键词："干旱""节水""精准"。 抗旱稳产 "良种"先行 5月以来，河南全省平均降水量为49.7毫米，较常年同期偏少42%；陕西3—5月平均降水量70.7毫米，较常年同期偏少42.4%。如此严重的干旱，对小麦产量 的影响有多大？ 记者在陕西省渭南市大荔县的一家农场看到，尽管今年当地降水量锐减八成，尤其是在小麦生长关键的拔节抽穗期几乎没有有效降水，但小麦的产量并未下 降。 河南省新乡县七里营镇种粮大户 马有永：这块地是偏沙质地，产量每年都在800斤左右。今年我们种了个新品种，预计能收到每亩1100斤左右。 马有永提到的新品种，今年首次进行大田繁育。在无有效降雨的严峻条件下，其抗旱性能表现突出。为培育更多抗逆品种，新乡市正攻关种业核心技术，已 成功选育农作物优良新 ...

Group 1 - The current wheat harvest season is in full swing, with significant activity in regions such as southeastern Hebei, northeastern Henan, most of Shandong, northern Jiangsu, and central Shaanxi [1][18] - In Henan province, specifically in Hebi City, 1.35 million acres of wheat are being harvested, with 620,000 acres showing increased yield due to demonstration fields [1][18] - The wheat in the high-yield demonstration fields has a density of approximately 520,000 ears per acre, which is 100,000 more than typical fields, and is expected to yield over 900 kilograms per acre in 2025 [6][9] Group 2 - The high-yield demonstration fields utilize a new wheat variety set to be released in 2024, characterized by short stalks and large ears, which are more resistant to drought and lodging [9][14] - The breeding process for these new varieties takes about 10 years, ensuring that only the best materials are selected for market release, contributing to stable grain production [14] - Advanced agricultural machinery, including automated navigation combine harvesters, is being employed to enhance harvesting efficiency and demonstrate the benefits of new technologies [16][19] Group 3 - As of June 8, 2023, the wheat harvesting progress in Hebi City reached 83%, with completion expected around June 10, and recommendations for timely summer corn planting [18] - The Ministry of Agriculture and Rural Affairs projects that over 17 million agricultural machines will be deployed during the summer harvest, incorporating advanced technologies like Beidou navigation and smart sensors [19] - In Shandong's unmanned farm demonstration base, autonomous machines are performing both wheat harvesting and corn planting, showcasing advancements in agricultural automation [22][24]
