根据双季优质稻规模种植的生育期、产量结构、气象条件、气象灾害、灾后影响进行观测和田间试验调查,分析和研究了双季稻生育期间的气候状况、产量与气象条件的关系、农业气象灾害对双季稻的影响,以及规模种植高产稳产的农业气象条件,生育期天数、产量与积温之间的关系。确定了充分利用气候资源合理搭配不同熟期品种、安排适宜的生产期及耕作栽培方法的高产稳产措施,最后提出了双季优质稻规模种植高产稳产的农业气象技术建议和气象防灾减灾措施。
According to the growth period, yield structure, meteorological conditions, meteorological disasters and post-disaster impacts of double cropping high-quality rice, the survey and field experiments were conducted to investigate and analyze the relationship between climatic conditions, yield and meteorological conditions during the growth period of double cropping rice. The impact of meteorological disasters on double cropping rice, the agro-meteorological conditions of high and stable yielding on a large scale, the number of days of growing period, the relationship between yield and accumulated temperature. The measures to make full use of climatic resources to match different maturity varieties, arrange appropriate production period and cultivation and cultivation methods were put forward. Finally, the suggestion of agricultural meteorological technology with high and stable yield in double-season high-quality rice and meteorological disaster prevention and mitigation measures were put forward.
