摘要
当前各级政府紧抓粮食安全,不断出台鼓励政策,以促进提高产量.再生稻作为一种提高产量的生产措施,正在得到政府和种植主体的重视.文章通过对 7 个杂交中稻做再生稻的再生能力及产量进行比较,筛选出适宜安徽沿江江南地区的再生稻品种,促进提高当地水稻产量.结果表明,新两优 611 和六两优香 11 再生能力强、产量高,综合表现最好;鑫两优香 128、友两优 2152、荃优 1606 高节位再生能力强,再生季产量表现高于对照;旱优 116、旱优 73 头季稻产量较高,再生能力一般、再生季产量较低.对比品种再生能力及产量表现,选择再生稻品种时,头季稻每 hm2 穗数高的品种,两季产量高.
Abstract
At present,governments at all levels are closely monitoring food security and continuously introducing incentive policies to promote increased production.Regenerated rice,as a production measure to increase yield,is receiving attention from the government and planting entities.This article compares the regeneration ability and yield of seven hybrid medium rice varieties as regenerative rice,selects suitable varieties of regenerative rice for the Jiangnan region along the Yangtze River in Anhui,and promotes the improvement of local rice yield.The results showed that Xinliangyou 611 and Liuliangyou Xiang11 had strong regeneration ability,high yield,and the best overall performance;Xinliangyouxiang 128,Youliangyou 2152 and Quanyou 1606 have strong high node regeneration ability,and their yield performance during the regeneration season is higher than that of the control;The first season rice of Hanyou 116 and Hanyou 73 has higher yield,average regeneration ability,and lower yield in the regeneration season.Comparing the regeneration ability and yield performance of different rice varieties,when selecting regenerated rice varieties,the varieties with higher panicles per hectare in the first season will have higher yields in the two seasons.
