生产实践和试验结果证明,我区晚稻产量不稳定,与气象条件有着密切的关系。本文以晚稻中熟品种团结一号在柳州沙塘1975—84年共十年的分期播种试验(一般于5月31日起每10天播一期,插植规格6×4寸,每穴5—8苗,按中、上生产水平进行水肥管理),以及1980、82—84年四年调查的生长量测定资料,着重统计分析晚稻茎蘖、叶面积、干物质和产量因子变化与气象条件的关系,供栽培管理和气候资源利用参考。
Production practices and test results show that the output of late rice in our region is unstable and has a close relationship with meteorological conditions. In this paper, the mid-maturing varieties of late rice unity No. 1 in Shacheng, Liuzhou in 1975-84 a total of ten years of seeding trials (usually on May 31 broadcast every 10 days, planting specifications 6 × 4 inch, 5 per hole -8 seedlings, according to medium and on the level of production of water and fertilizer management), as well as 1980, 82-84 years of investigation of the growth measured data, focusing on statistical analysis of late rice tiller, leaf area, dry matter and yield factors and meteorological conditions For the cultivation and management and utilization of climate resources reference.
