启东棉花新品种产量与气象条件关系的研究

Relationship between New Varieties of Cotton Production and Weather Conditions in Qidong City

在同一农业气候环境、栽培技术条件下,对棉花9个新品种作了试验,结果产量居于前三名的分别为科棉3号、中棉所47和南抗9号,增产潜力较大;同时经棉花生长关键期的气候因子对气候产量的模拟、线性定量化鉴定,可以在本地推广种植。

Basing on the same agro-climatic environment, cultivation techniques, the production of nine new va- rieties of cotton were tested. The results show that the yield residing in the top three were Kemian3, CCRI 47 and Nankang 9, with large yield potential.The analog of climatic factors on the climate production during the critical period of cotton growth proves that the new varieties of cotton can be promoted cultivation locally.
