当前，河南小麦春季田管进入关键窗口。受去年秋季持续降水影响，该省小麦晚播面积大、冬前长势 弱。农业部门建议，春季管理当早抓细管，早着手、早管理，细分苗情，因苗施策精细管理。 此前，河南省农业农村厅印发《奋战140天强春管促壮苗抗灾夺夏粮丰收行动方案》，要求早管、细 管、重管，对三类弱苗麦田，要及早落实追施返青肥、浇灌返青水措施，促苗早发快长。对一、二类麦 田，促控结合，加强起身拔节期肥水运筹，保苗稳健生长。 中新网郑州2月18日电(记者 韩章云)18日是雨水节气，河南多地晴朗持续，升温加码，暖意融融。根据 气象部门研判，当前气象条件对河南小麦返青起身总体有利。 河南是中国小麦主产区。当下，该省8500多万亩小麦已全面进入返青起身期。据河南省气象科学研究所 监测数据，前期河南气温偏高，日照充足，墒情适宜，气象条件对小麦返青起身总体有利。 数据显示，目前河南全省大部地区土壤墒情适宜，全省0—20厘米适宜测站比例为56%，土壤偏湿测站 比例为26%，干旱测站比例为18%；30—50厘米土壤适宜测站比例为54%，偏湿测站比例为38%，干旱 测站比例为8%。 据农业农村部通报和河南省植物保护检疫站专家会商研判，今年河南 ...

Core Viewpoint - The current wheat production in Henan province is characterized by a significant area of late sowing and a high proportion of third-class seedlings, with overall growth conditions better than expected due to favorable weather following sowing [2][3]. Group 1: Current Characteristics of Wheat Production - The late sowing area is large, with a high proportion of third-class seedlings and complex seedling types [2] - The sowing was delayed by 10-15 days on average due to persistent rainy weather last autumn, with some areas delayed by up to 20-30 days [2] - Despite the late sowing, favorable weather conditions since sowing have improved seedling growth, leading to a "small but strong" seedling status [2] Group 2: Perspectives on Wheat Production Situation - Caution is advised; while historical data shows late sowing can lead to increased yields, the outcome depends on two critical variables: scientific management of wheat fields and favorable weather conditions [3] Group 3: Favorable and Unfavorable Factors for Wheat Production - Favorable factors include sufficient soil moisture, high seed quality due to good moisture conditions, and favorable temperatures for root development and safe overwintering [4] - Unfavorable factors include risks of extreme weather events such as strong cold snaps and droughts, challenges from early spring conditions, and increased pest and disease pressures due to higher winter temperatures [4] Group 4: Key Measures for Spring Management - Spring management is crucial for determining yield potential; key measures include temperature maintenance, moisture conservation, and promoting early growth [5] - Timely soil management practices such as rolling and hoeing after soil thawing can enhance temperature and moisture retention [5] - Fertilization and irrigation should be carefully timed to avoid negative impacts on soil temperature and seedling recovery [5] - Monitoring and controlling pests and diseases is essential, with attention to weather conditions to prevent chemical damage [5] - Precautions against late spring cold snaps are necessary, particularly in April, with timely irrigation and soil management recommended [5]
