摘要
【目的】为了筛选出适合灵山县那隆镇种植的高产、优质、高抗的水稻良种,对望两优511、YC508、深两优841、YC1504、谷优367、深优9595、良丰838、建优2号8个早稻品种进行了品种比较试验。【方法】采用大区简比设计,每区面积330m^2。【结果】深两优841位居试验第一,产量678kg/667m^2;第二,YC508和YC1504并列,产量648kg/667m^2;第三,望两优511,产量600kg/667m^2;第四,良丰优838,产量546kg/667m^2;第五,深优9595,产量540kg/667m^2;第六,谷优367,产量528kg/667m^2;第七,建优2号,产量510kg/667m^2。【结论】望两优511、YC508、深两优841和YC1504等四个组合,产量高,生育期适中,株叶形态好,抗性强,适宜本地推广种植;谷优367和良丰优838两个组合叶片偏大较疲软,抗倒性一般,不适宜高产栽培;深优9595组合,中前期表现抗寒性较差,生长不很理想,是否适宜灵山县那隆镇推广,还要进行多造试种示范;建优2号生育期只有102d,适宜搞冬种和早春迟播地方选用,不宜大面积推广。
To filter out the rice variety of high yield, quality, and lodging-resistant capability for Nalong Town planting, conduct the variety compared trail of early season rice, including eight varieties：Wangliangyou511, YC508, Shenliangyou 841, YC1504, Guyou 367, Shenyou 9595, Liangfeng 838 and No.2Jianyou,which applying simple region design, the area of each region is 330 m2. The results show that four combinations such as Wangliangyou 511, YC508, Shenliangyou 841, YC1504, with the follow advantage：high yield,proper reproductive period, nice leaf shape, strong resistance,which is suitable for local cultivation. The combinations of Guyou 367 and Liangfengyou 838 with the disadvantage： large and weaker leaves, moderate lodging resistance, which is not suitable for local cultivation. The combinations of Shenyou 9595, with the performance of poorer cold resistance in early-middle period, unsatisfactory growth, whether appropriate for promoting in Nalong Town, still need more times trail.The variety of No.2 Jianyou, the reproductive period is only 102 days, which is suitable for local selection in the place of sowing in winter and late spring, but not good for promoting in large scale.
