摘要
【目的】筛选出适宜当地生态环境生长的优质高产水稻品种,为该地区大田生产良种良法栽培提供科学依据。【方法】采用随机区组排列,无重复,设6个处理,即每个品种为一个处理,以"深95优华占"为对照(CK),通过田间对比试验,对六个水稻品种的生育期、经济性状及丰产性进行比较分析。【结果】"早丰优华占"品种生育期最短,为125d,"c两优华占"全生育期最长,为138d;"C两优9号"、"五优新占"及"欣荣优华占"株高均超过100cm,株高最高为"欣荣优华占",为101.4cm;每兜有效穗数差距不明显,而每穗实粒数最多的为"欣荣优华占",达到平均每穗175.9粒,最低为每穗158.9粒的"早丰优华占";平均每穗秕谷数最低的为"五优新占"和"深95优华占",分别为5粒和7.2粒。【结论】"欣荣优华占"和"五优新占"产量最高,其中"欣荣优华占"表现良好,具有分蘖能力强,茎秆粗壮,剑叶长挺,全生育期适中,结实率高等特点,明显优于对照组"深95优华占",可作为柳州市融安县示范推广品种。"C两优9号"、"早丰优华占"、"c两优华占"产量均比对照组"深95优华占"低,其中"早丰优华占"、"C两优华占"具有轻微的穗颈瘟和纹枯病,不可进行推广。
【Objective】Selecting good quality and high yield variety of paddy rice which suitable for the growth of the local ecological environment, provide a scientific basis for field cultivation.【Method】Conducted field contrast test,applying the arrange of randomized block without repetition, six processing, namely each variety is a process. Compares with the variety of Shen 95 Youhua, compares and analysis rice growth period,economic character and yielding ability.【Results】For rice growth period, the variety of Zaofeng youhua is the shortest, while C liangyou hua is the longest;the variety of Xinrongyouhuazhan, with the advantage of plant height and grain numbers per ear;【Conclusion】The two varieties of Xinrongyouhuazhan and Wuyouxinzhan with the advantage of high yield, which can be the promotion in Rong＇an County; while the varieties of Zaofenghuayouzhan and CLiangyouzhan with the disadvantage of Panicle neck blast and sheath blight, which is non suitable for promotion.
