我省在连作晚稻抽穗开花期间,往往由于低温影响,增加■谷,影响产量。为探求连作晚稻抽穗开花结实与气象条件的关系,研究其规律,寻找安全抽穗期的农业气象指标,使得生产实践上能根据本地气象条件,早作准备,采取必要措施,避免或减少低温等不利因子对开花结实的危害,现根据有关晚稻试验和调查结果,对照气象资料,作初步综合分析如下。 During the period of heading and flowering of late rice in continuous cropping in our province, grain yield is often increased due to the influence of low temperature. In order to explore the relationship between the flowering and fruiting and the meteorological conditions of successive cropping of late rice, to study the law and to find the agrometeorological indicator of safe heading date, the production practice can make preparations according to the local weather conditions and take the necessary measures to avoid or reduce the disadvantages such as low temperature Factors on the flowering and fruiting harm, now based on the late rice test and survey results, the control meteorological data for a preliminary comprehensive analysis is as follows.
