摘要
今年(2024年)冬小麦秋播形势总体有利,一是底墒普遍比较充足,有利于适墒播种.二是种子质量好,数量充足,能满足秋播用种需求.不利因素主要是自然灾害频发、重发,气象条件不确定性大.秋播关键技术以"四适"(适墒、适期、适量、适深)为主线,冬前管理围绕"四关键"(关键时期、关键地区、关键环节、关键技术),突出抓好"三环节"(整好地、播好种、出好苗),落实落细"双镇压"(播前镇压、播后镇压),努力实现"一提高"(提高冬前一类苗比例),奠定2025年小麦丰产基础.
Abstract
The overall situation for autumn sowing of wheat this year(2024)is favorable.Firstly,the soil moisture is generally sufficient,which is conducive to sowing with suitable soil moisture;Secondly,the seeds have good quality and sufficient quantity,which can meet the needs of autumn sowing.The main unfavorable factors are frequent natural disasters and high uncertainty in meteorological conditions.The key technologies for autumn sowing and pre-winter management are centered around the"four suitability"of suitable soil moisture,suitable period,reasonable amount,appropriate depth,focusing on the"four key"aspects(key period,key area,key link,and key technology).Emphasis is placed on the"three links"(good land,good sowing,and good seedlings),implementing the"double suppression"(pre-sowing compacting and post-sowing compacting),striving to achieve"one improvement"(increase the proportion of the first-class seedlings before winter),and laying the foundation for high wheat yields in the coming year(2025).
