岱字棉15号,是本省推广的丰产质优的改良棉品种,它唯一的缺点是成熟期较晚。因此,如何给以适当的条件提早它的成熟期,对目前两热生产来说,是具有现实意义的。 1955年,我们在武昌县国营农场进行了棉花春化试验,就是根据上述的目的来进行的。工作开始时,首先进行棉籽精细的粒选,发芽率达95％,百粒重10.7克,用烘乾法求得种子含水量为12％。 试验分作两个处理:第一处理每百斤种子加水63斤,分3次加入,水温32℃,每次加水约隔6小时。在第一及第三次加水时并加入1％福尔马林消毒。加水後用消毒麻袋压紧。自堆温上升互25.5℃时算起,保持堆揾258—30℃,春化8天。春化结束时,
Dai word cotton 15, is the province to promote high yield and quality of improved cotton varieties, its only drawback is the late maturity. Therefore, how to give early maturity to the proper conditions is of practical significance for the current two hot production. In 1955, we conducted a cotton vernalization test at the Wuchang County State Farm, based on the above objectives. At the beginning of the work, the fine granulation of cottonseed was carried out firstly, the germination rate was 95%, the weight of 10 seeds was 10.7g, and the moisture content of seeds was 12% by drying method. Test points for two treatment: The first treatment of water per kg of seed add 63 pounds, divided into 3 times to join, water temperature 32 ℃, about 6 hours each water. In the first and third add water and add 1% formalin disinfection. Add water disinfection sack compression. Since the heap temperature rise 25.5 ℃ each other from time to time, keep the heap 258-30 ℃, vernalization 8 days. At the end of vernalization,
