2010年,根据江西省农技推广总站“籼改粳”生产发展规划的安排,修水县开始实施“北粳南移”工作,通过多个粳稻品种对比试验,发现甬优12表现较好。为更好地掌握该品种的特征特性,探究高产高效栽培技术措施,2011~2013年,修水县在多个乡镇开展示范栽培。结果表明:甬优12高产性、稳产性及适应性较好,示范田块平均亩产量超700 kg,较籼稻天优华占(对照)每亩增产160 kg以上,增幅突破30%。总结了甬优12配套高产栽培技术,供读者参考。 In 2010, according to the arrangement of Jiangxi Province Agricultural Technology Extension Station “indica to japonica ” production and development planning, Xiushui County began to carry out the work of “North Japonica Southward Shift”, and through comparative experiments on several japonica varieties, it was found that Yongyou 12 Better performance. In order to better understand the characteristics and characteristics of this variety and to explore high-yielding and efficient cultivation techniques and measures, from 2011 to 2013, Xiu-Shui County conducted demonstration cultivation in several townships. The results showed that the yield, the yield and the adaptability of Yongyou 12 were better. The average yield per hectare of the model plots exceeded 700 kg, which was 160 kg more than that of the indica rice Tianyouhua (control), an increase of more than 30%. Summed up Yongyou 12 supporting high-yielding cultivation techniques, for readers reference.
