在杂交水稻制种中,母本插植和管理的工作量很大,为解决这个问题,我们做了直播试验。早稻实施面积7亩,其中直播6.7亩,总产1502公斤,平均亩产224.2公斤,对照插植面积0.3亩,总产46.9公斤,亩产166.4公斤,母本直播的制种亩产比插植的增加67.8公斤,增长30.2%。晚造试验面积4.1亩,其中直播面积2亩,总产181.5公斤,亩产90.8公斤,比插植的2.1亩(总产141.5公斤,亩产62.4公斤)亩增产23.4公斤,增长25.7%。母本采用直播的亩用种2公斤,从间出的秧苗数量看,亩用种1.5公
In the hybrid rice seed production, the female parent planting and management of the workload, in order to solve this problem, we did a live broadcast test. Early rice implementation area of 7 acres, of which 6.7 acres of live broadcast, a total of 1502 kilograms, an average yield of 224.2 kilograms, control planting area of 0.3 acres, a total output of 46.9 kilograms, 166.4 kilograms per mu, An increase of 67.8 kg, an increase of 30.2%. Late test area of 4.1 acres, of which 2 acres of live broadcast area, a total output of 181.5 kilograms, 90.8 kilograms per mu than planted 2.1 acres (total 141.5 kilograms, 62.4 kilograms per mu) mu yield 23.4 kilograms, an increase of 25.7%. The mother of live acres with 2 kg, from the number of seedlings out of view, mu with 1.5 species

在距离地面大约3.6万千米的地球同步轨道上，一座太阳能发电站永不停歇地收集着太阳能，并源源不断地把电力传回地球供我们使用。这似乎只存在于科学幻想之中。不过，最近日本科学家的系列研究成果让人们看到了将其变成现实的可能性。 前不久，日本的研究人员两次成功实验了微波无线输电，一次是将1.8千瓦的电力（足够用来启动电水壶）以微波无线方式，精准传输到55米外的接收装置，一次是将10千瓦电力转换成微波后输送
