近几年随着水稻价格的不断上涨,水稻种植面积也不断提高,取得了显著的社会效益和经济效益,但目前水稻生产仍然存在着品种过于单一,单一品种种植面积大,抵抗自然灾害能力差等多种不利因素。因此,要保证水稻的稳定发展,我们选择了较适合当地种植的21个品种(品系)进行对比试验,筛选出适合本地区种植的水稻品种(品系),改变当前水稻品种单一的局面。试验采用小区对比法,21个品种(品系)在水稻“三化”栽培模式下的生育特性和产量性状,主要筛选出适合本地区的优良水稻品种。结果表明:三江一号、龙粳25、龙粳26、龙粳29、龙粳31、龙交04-908这几个品种(品系)在生育期、抗性、丰产性等几个方面表现较好。
In recent years, with the continuous increase of rice prices, the area under rice cultivation has also been continuously improved, and remarkable social and economic benefits have been achieved. At present, rice production still has single varieties, single cultivated areas and poor resistance to natural disasters And many other negative factors. Therefore, in order to ensure the stable development of rice, we selected 21 cultivars (lines) that are more suitable for local cultivation and conducted comparative experiments to screen out rice varieties (lines) that are suitable for planting in this area and change the single situation of current rice varieties. In the experiment, the characteristics of fertility and yield of 21 cultivars (lines) under the “three cultivation” mode of paddy field were compared by plot comparison method, and the best rice varieties suitable for this area were screened out. The results showed that Sanjian 1, Longjing 25, Longjing 26, Longjing 29, Longjing 31 and Longjiao 04-908 had better reproductive performance, resistance and high yield it is good.
