粳稻品种垦育28号的选育与应用

Breeding and Application of Japonica Rice Variety Kenyu No.28

为了培育优质、高产水稻新品种,河北省农林科学院滨海农业研究所以冀粳14号为母本、垦育12号为父本杂交,再经回交,对其杂交后代定向选育,2000年获得优异稳定品系,2004年通过河北省农作物品种审定委员会审定,定名为垦育28号。该品种适于旱育秧、工厂化育秧及节水栽培技术,秧田播种量为1 200～1 800 kg/hm2。施肥应注意前重后轻,施肥量为纯氮225.0～262.5 kg/hm2。注意N、P、K合理配合以及病虫害的防治,盐碱地施锌肥20.0 kg/hm2,以防缩苗。

The new japonica rice variety Kenyu No.28 was bred by crossing between Kenyu No.12 and Jijing No.14 by the Research Institute of Coastal Agriculture,Hebei Academy of Agriculture and Forestry Sciences,which was approved by Hebei Crop Variety Approval Committee in 2004.The dry nursery seedling,factory seedling and water saving cultivation techniques were suitable for this variety.The sowing rate was 1 200-1 800 kg/hm2 in autumn.The application rate of pure N was 225.0-262.5 kg/hm2.20.0 kg/hm2 zinc fertilizer was used in the saline-alkali soil for preventing stunt disease.
