摘要: 大穗型迟熟组合Ⅱ优6078,在川东温光资源良好地区,通过大棚旱育秧早播、早栽、稀植,结果在头季取得较生产上主推组合增产10%以上产量的同时,中稻熟期较其在本地常规(或适期范围内)播种的水育秧提早成熟3-4天,为再生稻的生产创造了有利条件。一般产量2700kg/hm2,高的可达3000kg/hm2以上,弥补了按水育秧种植难以取得再生稻的不足,为川东温、光资源良好地区从事大穗品种中稻-再生稻生产,深入挖掘其生产潜力提供了依据。

Abstract: According to the test, in the thermo-photo-sufficient areas of the eastern part of Sichuan Province, by means of raising seedings drily so as to sow early and transplant seedings early and undersly, the big-eared by brid rice Ⅱ-you6078 could be advanced with its ripe period 3-4 days shorter than the rice that was sowed in suitable period and the seedings of which was raised in water in the same areas and the yield of ratooning rice could be gained, of which the usual is 2700kg per hectre and the high could be 3000kg or more per hectare as well as the yeild of middle-season rice was increased 10 or more percent more than the main-applying hybrid rice varieries. This test could provide proots of applying big-eared hybrid rice varieties to plant as middle-season rice and rataooning rice and reseaching its potential yeild deeply in this areas.
