Ⅱ优航1号是福建省主推的超级稻新组合,2006年本市组织进行了0.2万hm2的核心示范种植,其中有33.5hm2面积的示范区,两季稻亩产超过1t。通过示范片6个点抽样调查,结果表明,Ⅱ优航1号头季稻夺取高产的主要途径是在充分发挥其穗大粒多,结实率高的优势基础上,力争足够的穗数;再生稻,争取有效穗数是其获得高产的关键,因此,应重施芽肥,培育壮芽,高留桩,提高植株上部腋芽。
Ⅱ Youhang No.1 is the new super rice combination mainly promoted by Fujian Province. In 2006, the city organized a core demonstration planting of 0.2 million hm2, of which 33.5hm2 has a demonstration area of more than 1t. Through the sample survey of 6 spots, the results showed that the main way to seize high yield of the first crop of Ⅱyouhang 1 was to make full use of the advantages of large spikelets and high seed setting rate, and to strive for sufficient number of spikes; , To obtain effective panicles is the key to its high yield, therefore, should be re-sprout fat, nurturing strong buds, high pile, to improve plant upper axillary buds.
