杂交水稻具有明显的增产优势,在水稻生产中占有重要地位。特别是杂交晚稻,产量高、米质佳、经济效益好,深受广大农民欢迎。但是,由于栽培措施不当,目前杂交晚稻(以下简晚杂)单产悬殊很大,影响了其增产潜力的发挥。为此,我们于1988～1989年在江西省不同地区进行了调查,以明确不同熟期杂交组合、不同种植地区以及不同生产水平下进一步提高单产的主攻方向,为杂交水稻高产栽培技术措施的拟订提供依据。
Hybrid rice has a significant yield advantage, occupies an important position in rice production. Especially hybrid late rice, high yield, good quality rice, good economic returns, welcomed by the majority of farmers. However, due to improper cultivation measures, the yield of hybrid late rice (hereinafter briefly referred to as “Miscellaneous Crops”) is greatly disproportionate, affecting its potential for increasing production. To this end, we conducted surveys in different regions of Jiangxi Province from 1988 to 1989 to clarify the main directions for further improving yield per hectare under different maturity hybrid combinations, different planting areas and different production levels, so as to formulate the technical measures for high yielding cultivation of hybrid rice Provide evidence.
