1977年我省组织了十二个气象站、哨、点参加的杂交稻气象问题研究试验网,进行了杂交水稻的农业气象协作试验,以期弄清杂交水稻各主要生育时期和气象条件的关系,为杂交水稻的高产栽培提供气象依据。 试验采用分期播种法,统一于4月17日至6月22日分九期播栽(汕优2号自5月5日始播)。每期设两个重复。小区面积为15平方米,间隔顺序排列。栽插密度5×7(寸),单本栽插。栽培管理水平力求统一。整个生育期中对杂交稻的生育状况和气象条件进行平行观测。观测方法和内容各点统一。以抽穗扬花期为重点。供试品种为南优2、3、6、号和汕优2号。
In 1977, the province organized 12 meteorological stations, whistles and spots to participate in the hybrid rice meteorological research network, carried out the hybrid rice agrometeorological cooperation experiments in order to understand the main hybrid rice growth period and the meteorological conditions, Provide meteorological basis for high yielding cultivation of hybrid rice. The test was carried out by staged sowing method, unified in April 17 to June 22, nine sowing (Shanyou 2 since May 5 broadcast). Set up two repetitions for each period. Residential area of 15 square meters, arranged in order. Transplanting density 5 × 7 (inch), single planting. Cultivation and management standards and strive to unity. The whole growth period of hybrid rice fertility and weather conditions were observed in parallel. Observation methods and content of the unity of all points. To flowering and flowering as the focus. Test varieties for the Southern You 2, 3, 6 and No. 2 Shanyou.
