 Experimental results obtained both in laboratory and in the field plots showed that the dusting of lime on leaves of infected plants was effective to a certain extent in controlling the disease. But the method is not considered to be practicable, because the disease becomes serious only in rainy seasons, and the lime applied on the plants is easily washed away by rains.

Experimental results obtained both in laboratory and in the field plots showed that the dusting of lime on leaves of infected plants was effective to a certain extent in controlling the disease. But the method is not considered to be practicable, because the disease becomes serious only in rainy seasons, and the lime applied on the plants is easily washed away by rains. Since the disease is confirmed to be chiefly carried by seeds, a field control experiment was conducted to combat the disease by using disinfested seeds. Seeds were collected from disease affected fields, and were treated with 0.5% solution ef granosan or ceresan for 3 hours or with 0.2% solution of granosan for 15 hours. A total of 13055 kilos of treated seeds were sown and grown in 768 mows of rice fields, while a total of 2689 kilos of non-treated seeds grown in 239 mows of rice fields were used as control. The results showed that the treated seeds gave rise to very much fewer diseased seedlings in the seed beds, and that the severity of the disease was very much lighter in the treated fields than in the control. It is thus concluded that the seed treatments stated above were not effective enough to completely disinfest the seeds. Another field control experiments by using disease-free seeds were also conducted. Seeds collected from disease-free fields were used, and the weeds especially the Leersia hexandra Swartz. around the fields were eradicated. The same experiment was carried out 4 times consecutively in a field of more than 100 mows in Canton in the years of 1956 and 1957, and again in a field of 3600 mows in Chung-Hwa district in the Spring of 1958. The results all turned out fine, and the disease was successfully controlled in all cases. But since the Leersia weed has not yet been confirmed to be a natural host of the disease, its eradication may not be necessary in the field control of the present disease. This remains to be a problem that needs further investigation. 1955年室內和大田噴撒石灰粉的防治試驗結果說明,在雨后天晴的情况下噴撒石灰粉有一定的防治效果。 1958年春曾进行了1007亩(其中对照239亩)种子消毒的防治試驗。用0.5％的西力生或賽力散燜种3小时,或用0.2％西力生浸种12小时,种子发芽率不受影响,苗期发病率显著降低,大田发病日期稍为延迟,发病严重度大为減輕。 1956—1957年早晚季連續四次(每次試驗面积100亩以上)进行换用无病田种子及剷除李氏禾杂草的大田防治試驗,防治結果都很好。1958年春季在从化县街口公社国星大队成功地完成了大面积(3600亩)的防治示范試驗,全部不发病。但是,李氏禾是否本病的野生寄主,剷除李氏禾在防治上是否必要,尚有不同看法,有待进一步研究。 Under the combine action of the Pacific Plate underthrusting the Euroasian Plate and the northward push of the Indian Plate from the south, the principal axis of the compressional stress of the Hopei Province of North China and its surrounding regions is northeast-southwest in direction. In connection with such a field of stress, the main tectonic movement of the Hopei Province as a whole, particularly its Neo-tectonics was considered to be bounded by the rift belt in front of the Tai-hangshan Eange.

Under the combine action of the Pacific Plate underthrusting the Euroasian Plate and the northward push of the Indian Plate from the south, the principal axis of the compressional stress of the Hopei Province of North China and its surrounding regions is northeast-southwest in direction. In connection with such a field of stress, the main tectonic movement of the Hopei Province as a whole, particularly its Neo-tectonics was considered to be bounded by the rift belt in front of the Tai-hangshan Eange. On both sides of this bclt there appeared continuous vertical differential motions. At the same time, there existed a component of right lateral horizontal movement. In accordance with these facts, the time and space distribution of the seismic activity of the Hopei Province since the 16th century, could be supposed that the rift belt in front of the Taihangshan Eange formed the "Central Ridge", along which earthquake epicenters migrated in the northsouth direction. In studying the seismic activity immediately before the 1679 Shanho-Bingkuo Earthquake-of Magnitude 8 and the 1830 Szehsien Earthquake of magnitude 7.5, it has been inferred that an earthquake of magnitude greater than 7 probably will occur around 1980 in the northern part of the Hopei Province. 在太平洋板块向西对欧亚板块俯冲以及印度板块向北推挤的共同作用下,河北省及其邻近地区的主压应力轴是北东东—南西西向。在这样的应力场作用下,河北省的主要构造运动特别是新构造运动形态是以太行山前断裂带为界,其两侧有大面积的继承性的升降差异运动,在升降运动中同时还有右旋的水平分量。与此相应,十六世纪以来,河北省的地震活动在时空分布上有以太行山前断裂带为“中脊”呈南北向迁移的特征。在进一步探讨了1679年三河、平谷8级地震与1830年磁县7.5级地震的前震活动特征之后,提出1980年前后河北省北部有发生7级以上地震的可能。 Letd K=K_o((-1)~(1/2)) where K_o is a field of characteristic P>3 (K(?)K_o).
