摘要
为筛选适宜荆门地区机插的优质高产高抗水稻品种,以丰两优4号为对照,选择了11个品质优良的中迟熟型两系或三系杂交稻品种进行机插品比试验。结果表明:相比对照丰两优4号,在屈家岭机插秧栽培方式下,E两优2071、隆两优1212秧苗较为粗壮,晶两优534、巨风优650秧苗较为瘦弱;各品种长势与丰两优4号相当,在8月中下旬抽穗,9月中下旬成熟,全生育期在120~130 d,结实率均在80%以上,比较耐高温,抗倒伏;隆两优1212、Y两优602、晶两优1212、隆两优华占、岗优725抗病性强于丰两优4号,其他品种相当或弱于丰两优4号;E两优2071、巨两优476、隆两优华占分蘖能力较强;晶两优1212、隆两优华占、巨风优650、晶两优534成穗率相对较高;最终实际产量高于丰两优4号的有E两优2071、隆两优1212、隆两优华占和隆两优534这4个品种,增产2.2%~6.6%。总体而言,隆两优534、隆两优华占综合性状较好,产量达到10 t/hm^(2)以上,适用于荆门地区中稻机械插秧生产。
In order to screen high-quality,high-yield and high-resistant rice varieties suitable for mechanical transplanting in Jingmen area,11 high-quality,medium-late cropping hybrid rice varieties(two-line and three-line)were selected for machine-transplanted seedling comparison tests with Fengliangyou No.4 as the control.The results showed that compared with the control Fengliangyou No.4,the seedlings of E Liangyou 2071 and Longliangyou 1212 were strong,and the seedlings of Jingliangyou 534 and Jufengyou 650 were thin under the mechanical transplanting cultivation mode in Qujialing.The growth of each variety was similar to that of Fengliangyou No.4,heading in mid-late August and maturing in mid-late September with a whole growth period of 120-130 d and a seed setting rate of above 80%.They were all resistant to high temperature and lodging;Longliangyou 1212,Y Liangyou 602,Jingliangyou 1212,Longliangyouhuazhan and Gangyou 725 had stronger disease resistances than Fengliangyou No.4,while other varieties were approximate to or weaker than Fengliangyou No.4 in disease resistances.E Liangyou 2071,Juliangyou 476 and Longliangyouhuazhan had a strong tillering ability;the ear formation rates of Jingliangyou 1212,Longliangyouhuazhan,Jufengyou 650 and Jingliangyou 534 were relatively high;the final actual yields of E Liangyou 2071,Longliangyou 1212,Longliangyouhuazhan and Longliangyou 534 were 2.2%-6.6%higher than that of Fengliangyou No.4.In general,Longliangyou 534 and Longliangyouhuazhan have good comprehensive characters,yielding over 10 t/hm^(2),which are middle rice suitable for mechanical transplanting in Jingmen area.
