中国援乍得水稻品比试验报告

Report on comparative test of rice varieties aided by China to Chad

乍得属于非洲中部,境内有两大河流,沿河水稻种植生态区较多,温光条件较好,但土地贫瘠,中国援助种植多年的中农1号已开始退化。为了在一个援乍周期内(3年)找出适宜当地种植的高产优质品种,援乍专家组安排进行了2年4个地点5个品种的区域试验。结果表明,黄占2号的产量、抗倒性明显优于对照中农1号,在乍得较恶劣自然天气状况下,可以取代中农1号成为主推品种。试验结果得到大田种植验证,较为理想。

Chad belongs to central Africa.There are two major rivers in Chad and has many rice planting ecological areas along the river.The temperature and light conditions are good,but the land is poor.Zhongnong No.1,which has been planted for many years by China,has begun to degenerate.In order to find high-yield and high-quality varieties suited to local cultivation within a three-year assistance cycle,a comparative test of 4 varieties at 4 areas in two year were arranged.The results showed that the Huangzhan No.2 were significantly superior to Zhongnong No.1 at yields and lodging resistance under the abominable nature conditions in Chad and could be the mainly extension variety.The experiment also achieved ideal results and verified by field planting.
