摘要

本研究系统调查了鄂香2号在3个典型示范点的示范表现,并小结了其单产600 kg/667 m2的高产栽培技术:无人机飞播用种量6~7 kg/667 m2或机械移栽基本苗6~7万/667 m2,可保其有较高的成穗数;纯氮用量15~16 kg/667 m2,N、P、K比为2∶1∶1.5,采用底肥为主的分次施肥策略,可保其全周期平衡的营养需求;草害防控重点放在“一封二杀”上,对主要病虫重点放在预防和发生初期防治上,保证病虫草害的有效控制。在此前提下,合理规划栽培期避开高温灌浆,确保适温下长时间灌浆和全生育期健康栽培,配合后期良好的天气,是该品种取得更高产和更优质的一条重要途径。

Abstract

This study systematically investigated the demonstration performance of Exiang 2 in three typical demonstration sites, and summarized its high-yield cultivation techniques with a yield of 600 kg/667 m2. The seeding rates for UAV oerial seeding at 6-7 kg/667 m2 for direct seeding or basic seedlings at 60,000~70,000/667 m2 for mechanical transplanting to ensure a large number of ears. The recommended total amount of nitrogen application was 15-16 kg/667 m2, with N∶P∶K of 2∶1∶1.5. Fertilization strategies mainly rely on basal supplemented by topdressing to ensure balanced nutritional requirements throughout the life cycle. The priority of weed control should be put on “one-time closure, two-time insecticides”, the control methods for pests and diseases focuses on prevention during initial stages. Under this premise, optimal growth period is required to avoid high temperature stress during grain-filling stage, and to maintain longer grain-filling under optimal temperature and healthy growth during the whole growth period, combined with good weather in the later period, which might be an important option to achieve higher yields and quality for this variety.
