连作晚稻抛秧已在我县大面积推广,我县绝大部分连晚抛秧品种为常规粳糯稻,但也有少量农户用杂交稻作抛秧品种。由于杂交稻秧龄较长,而且在秧田中分蘖较多,一般用561孔秧盘育秧较难,常因根系太长、太旺而串根,造成撕破秧盘,不易抛栽。因此许多农户不得不采用常规半旱秧田育秧,手拔手插,既增加劳动强度,又推迟季节。为此,1998年我们采用大孔径塑盘育苗,在上桥中心坊试种1.5公顷,在城关镇轻型栽培示范坊试种0.27公顷,取得了成功。抛秧品种为协优371,两点均于6月22日播种,上桥点于7月23～26日抛秧,城关镇点于7月20日抛栽,秧盘孔数
Continuous cropping rice throwing has been widely promoted in our county. Most of our county throw late rice varieties are conventional japonica glutinous rice, but a small number of farmers also use hybrid rice as seedling throwing varieties. Due to the longer seedling age of hybrid rice and more tillers in the seedling field, it is more difficult to seed the seedlings with the 561-hole seedling tray, often because the roots are too long and too prosperous and the roots are rooted. Therefore, many farmers have to use conventional semi-dry seedling nursery, hand and hand plug, both to increase labor intensity, but also postpone the season. To this end, in 1998 we used a large aperture plastic plate nursery, in the Bridge Center Square trial planting 1.5 hectares, in Chengguan Town Light Cultivation Model Square test 0.27 hectares, and achieved success. Throwing varieties for the Xieyou 371, two were sown on June 22, Shangqiao point in July 23 to 26 throwing transplanting, Chengguan town on July 20 cast planted seedling tray hole number
