摘　　要：本文分析了宣粳糯7号的选育过程及其特征特性,并从机插秧和直播两种栽培模式总结其作为麦茬稻的高产栽培技术。选育方面宣粳糯7号是以宣粳糯1号为母本,粳糯86120-5为父本经过系统选育而成的早熟晚粳糯稻品种,具有耐迟播、抗逆性强和适应性广等品种特性,适宜机插秧和直播作麦茬稻种植。作麦茬稻高产栽培技术原则是在有足够的有效穗数基础上,促壮秆、成大穗和增粒重,配合病虫草害防治。具体措施包括适时适量播种、科学肥水管理、综合防治病虫草害和适时收获等,机插秧还要求匀栽密植、插足基本苗。目的在于为该品种的推广种植提供参考。This article introduced the breeding process and characteristic characteristics of Xuanjingnuo No.7,and summarized the high-yield cultivation techniques as a wheat stubble rice from two cultivation models:machine transplanting and live broadcasting.Xuanjingnuo No.7 was an early maturing and late maturing glutinous rice variety developed through systematic breeding using Xuanjingnuo No.1 as the female parent and Jingnuo 86120-5 as the male parent.It had characteristics such as tolerance to late sowing,strong stress resistance,and wide adaptability,and was suitable for machine transplanting and direct seeding as wheat stubble rice cultivation.The principle of high-yield cultivation was to promote strong stems,large panicles,and increased grain weight on the basis of sufficient effective panicles,in conjunction with disease,insect,and weed control.Specific measures include timely and appropriate sowing,scientific fertilizer and water management,comprehensive prevention and control of diseases,pests and weeds,and timely harvesting.Machine transplanting also requires uniform planting and dense planting,and sufficient planting of basic seedlings.The purpose was to provide reference for the promotion and planting of this variety.
