摘要
湖南省湘阴县2018-2022年实施“三分地养活一个人”粮食高产绿色科技创新工程,承担双季优质超级稻周年生产模式示范项目,取得了较好的示范效果,与全县双季稻平均水平比,平均单产增加38.4%~48.1%,增效9 768.9~11 977元/hm^(2),纯氮减少19.8%~35.3%、纯磷减少42.7%~54.4%、纯钾减少11.9%~22.3%、农药减少35.3%~60.1%。总结分析了增产增收和节本增效情况,详细介绍了绿色优质高产栽培技术,并在品种优化、生产管理、抗灾稳产等方面提出了问题和建议。
From 2018 to 2022,the“Sanyi Project”grain high-yield green technology innovation project was carried out in Xiangyin County,Hunan Province.It undertook the annual production model demonstration of double-cropping high-quality super rice,and achieved good demonstration results.Compared with the average level,the average yield per unit area increased from 38.4%to 48.1%,the efficiency increase was from 9768.9 to 11977 yuan/hm^(2),the use of pure nitrogen per 100 kilograms of rice decreased from 19.8%to 35.3%,and the use of pure phosphorus decreased from 42.7%to 54.4%,the use of pure potassium reduced from 11.9%to 22.3%,the use of pesticides reduced from 35.35%to 60.1%.We summarized and analyzed the situation of increasing production and income,saving costs and increasing efficiency,introducedin detail the green,high-quality and high-yielding cultivation techniques,and put forward questions and suggestions in terms of variety optimization,production management,disaster resistance and stable production.
