摘　　要：根据湖南省高粱发展的现状,提出了高粱适宜种植范围;阐明了高粱高产高效栽培的5个技术环节:(1)做好种子准备、选地整土和施足基肥等播前准备;(2)根据区域气候条件、种植制度和品种特性搞好播种;(3)及时做好查苗补缺、间苗定苗、中耕除草和肥水运筹等田间管理;(4)根据预测预报搞好病虫害综合防治;(5)适时收获。同时,阐述了再生高粱的丰产管理技术措施:养蔸、砍秆和灌溉等技术;提出了肥料必须在砍秆后15 d内全部施完;明确了虫害防治的3个关键时期。基于此,形成了两季高粱高产高效综合配套栽培技术。According to the status of sorghum development in Hunan province, the suitable planting area of sorghum was put forward, and five technique links of cultivating sorghum for high yield and high efficiency were clarified in the paper：（1） doing preparation work before the sowing carefully, such as preparing seeds, selecting the land and basal dressing;（2） sowing according to regional climate conditions, cropping systems and variety characteristics;（3） carrying out field management timely, including checking and filling the vacancy, thinning and establishing seedlings, tillage and weeding, watering and fertilizer-dressing, etc.;（4） improving the comprehensive control of diseases and pests according to the forecast;（5） harvesting at the right time. Meanwhile, technical measures of high yield management of regenerated sorghum, including nourishing, cutting, irrigation techniques were described. It was put forward that fertilization must be finished in 15 d after cutting stems. The paper also explicated three critical times of the pest control. On this basis, systematic culture techniques for two season sorghum of high yield and high efficiency were developed.
