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，今年同样如此，持续干旱、高温、 大风日数偏多。此时恰逢小麦孕穗期至抽穗期，需要大量水分。麦田如果缺水干旱，会减少亩穗数，对穗粒数 也有较大影响。 河南是小麦种植大省，每年小麦播种面积达8500万亩。水肥一体化滴灌设备和技术正在快速推广应用。小麦 播种时，滴灌带随着播种机械一同铺设至田间，连接主管、接上水井后，浇地十分方便。亩次灌溉用水量由原 来的200立方米降为40立方米，减少了地下水抽取。另外，滴灌配合施肥罐，还能实现水肥一体化，降低了施 肥难度，也便于作物吸收。滴灌大大减少了劳动数量和劳动强度，管理起来比较轻松。因为滴灌可以做到少量 多次，根据农作物需求进行灌溉，保证了农作物一直处于比较良好的墒情中。 版权声明 证券时报各平台所有原创内容，未经书面授权，任何单位及个人不得转载。我社保留追 究相关 行 为主体 法律责任的权利。 转载与合作可联系证券时报小助理，微信ID：SecuritiesTimes END 滴灌本 ...

Core Insights - The agricultural sector is expected to achieve another bumper harvest this year, driven by advancements in agricultural technology, including irrigation and breeding techniques [1][2] - Traditional agriculture heavily relies on weather conditions, but recent years have seen increased instances of drought, which impacts crop yields [1] Group 1: Irrigation Technology - The adoption of water and fertilizer integrated drip irrigation technology is rapidly increasing, particularly in major wheat-producing regions like Henan, where the wheat planting area reaches 85 million acres [1] - Drip irrigation significantly reduces water usage from 200 cubic meters to 40 cubic meters per acre, minimizing groundwater extraction and improving efficiency [1] - This technology allows for precise irrigation based on crop needs, ensuring optimal soil moisture levels [1] Group 2: Drought-Resistant Crops - In areas with challenging conditions, such as hilly regions lacking irrigation, drought-resistant wheat varieties have been developed, with root systems extending over 3 meters [2] - In the Taklamakan Desert's saline-alkali land, winter wheat yields have reached 700 kilograms per acre through the use of drought-resistant and salt-tolerant varieties, along with integrated water and fertilizer management [2] Group 3: Agricultural Practices and Investment - The rise of large-scale farming operations has led to increased investment in labor-saving mechanized farming and the adoption of new technologies [2] - The support from a robust agricultural technology service group and enhanced manufacturing capabilities in China has created a favorable environment for agricultural development [2]
