有的同志认为四优30和威优30是感温型,我们曾经认为它们是弱感光型,这仅仅是根握它们的生育期的分析所得的观点。为了更正确、有效地推广四优30和威优30,我们用短日照处理的办法进行感光研究。研究方法将四优30及威优30于4月11日用塑料盘播种。5月4日秧苗6-7叶单本插于盆钵内,每盆两株,每组合各插16盆32株,作短日照处理。5月16日每株都有2-3个分蘖,开始短日照处理,每天日照8小时,早上8时30分到下午4时30分,其他时间都放在暗室内,共处理20天,6月7日停止处理。6月15日日将经过处理的稻株移入大田。5月4日每个组合取30株插在网室水田内,不进行遮光处理。网室及大田的栽培措施与一般大
Some comrades think that Siyou 30 and Weiyou 30 are temperature-sensitive types. We used to think that they were weaker models, and this is just the point of view of analyzing their growth period. In order to more accurately and effectively promote Siyou 30 and Weiyou 30, we conducted photographic studies using short-day treatment. The research method will Siyou 30 and Weiyou 30 on April 11 with plastic dishes. May 4 seedlings 6-7 leaf single inserted in the pot bowl, two per pot, each inserted 32 pots of 16 plants for short-day treatment. May 16 each plant has 2-3 tillers, began short-day treatment, 8 hours a day sunshine, 8:30 am to 4:30 pm, the other time on the dark room, a total of 20 days, 6 January 7 to stop processing. The treated rice plants were transferred to Daejeon on June 15. On May 4, 30 plants in each combination were inserted in the paddy field of Nethouse without shading treatment. Network room and Daejeon cultivation measures and general large
