早稻地膜育秧膜内温度的变化,受气温、日射量的直接影响。研究地膜膜内温度的变化规律及其气温、日射量的关系,以便采用相应的栽培管理措施,是生产上急待解决的一个重要课题。本研究通过膜内不同土层及地表温度的观察,增温效应与气温、日射量关系的分析,及其对秧苗冻害、成苗率、秧苗素质的影响,明确了地膜育秧膜内温度特点、适宜播期和相应的栽培管理措施。
Early rice film seedling film temperature changes, by the temperature, the amount of direct impact. It is an urgent task to study the variation law of the temperature inside the film and the relationship between the temperature and the amount of solar radiation in order to adopt the corresponding cultivation management measures. In this study, through the observation of different soil layers and surface temperature in the film, the relationship between warming effect and temperature and the amount of solar radiation, and the effects on frost damage, seedling formation rate and seedling quality of seedlings, Suitable sowing date and the corresponding cultivation management measures.
