从上海农业生物基因中心引进旱稻新品种中旱 3号进行试种 ,试验其生态适应性及产量潜力 ,探索其节水高效栽培技术 ,结果表明 :中旱 3号耐旱耐寒性强 ,中抗稻瘟病 ,适应性广 ,产量潜力较高 ,米质较好。旱种旱管、水插旱管栽培 ,一般单产达 4 5 0 0~ 5 0 0 0 kg/hm2 ,比巴西旱稻增产 10 %~ 2 0 %。穗大粒多 ,一般每 667m2有效穗 16万 ,水插旱管基本苗 8万 ,旱播旱管播种量 3 .0~ 3 .5 kg容易获得高产。
A new upland rice variety, Zhonghan 3, was introduced from Shanghai Agricultural Biogenetic Center to test its ecological adaptability and yield potential and to explore its water-saving and high-efficient cultivation techniques. The results showed that Zhonghan No.3 was strong tolerant to cold and cold, moderately resistant Blast, wide adaptability, high yield potential, better quality of rice. Dry-type dry pipe, water pipe planting drought, the general yield of 4500 ~ 50000kg / hm2, than in paddy rice yield 10% ~ 20%. Spike large grain, generally effective panicle per 667m2 160,000, water cuttings basic seedlings 80000, dry sowing dry pipe sowing 3 .0 ~ 3 .5 kg easy access to high yield.
