为了筛选出适合湖南地区栽培的再生稻品种,研究再生稻高产栽培技术.记录7个水稻品种的播种期、收获期及生育期,计算出再生稻每株分蘖数及每丛平均株数,比较其生育期、再生能力、产量及米质口感,筛选出最适合作为再生稻的品种,以该品种为研究材料,研究施肥时间、收割方式以及留桩高度对再生稻分蘖、高度和产量的影响,探索病虫害的防治方案,在湖南省内进行示范试验.结果表明:‘Y两优9918’作为再生稻品种,生育期短、再生能力强、产量高、米质口感优良;最佳施肥时间为第一季收获前7天左右;机收时,留桩高度以25～27 cm为宜;病虫害采用“一拌三喷”综合防治策略,再生稻产量可达到3000～4500 kg/hm2.构...

The objective is to screen suitable varieties of ratoon rice and study the high yield cultivationtechniques in Hunan.The sowing time,harvest time,growth period and the tiller number per plant,the averageplant number per clump of 7 rice varieties were recorded and calculated.The growth period,ratooning ability,yield,quality and taste were compared to select the suitable varieties as ratoon rice.Then taking the best oneas the study material,the influences of the fertilizing time,the way of harvest and stubble height on tillering,height and yield ...
