多年生产实践证明,在我省自然气候条件下,双季稻采用迟熟和中熟双季晚粳品种,有利于获得稳产高产。但是中熟,特别是迟熟双晚粳稠品种生育期长,其插秧期受头茬早稻收割期的限制,抽穗期又受开花授粉临界温度的限制,以致秧田生长期长;加之秧苗生长处于高温多湿,虫多病多的不利条件下,因而如何育足育好双晚适龄壮秧,就成为提高双晚产量,实现双季稻双季高产的关键。 近几年来,我省不少地方由于双晚秧苗育的好,其他栽培措施跟得上,双季晚稻年年丰 Years of production practice has proved that in our province under natural climatic conditions, double cropping rice and late maturing double maturity varieties, is conducive to stable and high yield. However, medium maturity, especially late maturing double late japonica varieties of a long period of growth, its heading season by the first crop of rice stubble Harvesting restrictions, heading and flowering pollination critical temperature limit, resulting in seedling growth period; coupled with seedling growth in Under the unfavorable conditions of high temperature and humidity, and more bugs, it becomes the key to increase double-night yield and achieve double-crop high yield in double cropping. In recent years, many places in our province due to double late seedling nurturing good, other cultivation measures keep up, double season late rice abundance
