摘要 对一季稻汕优 63、中籼 13 0 2 2 ,进行机械条播、人工撒播和人工育秧移栽的对比试验 ,结果表明 :机械条播比人工直播增产13 .9%,机械条播比人工移栽增产 2 0 .3 %,人工撒播比人工移栽增产 5 .5 %。因此 ,一季稻直播省工、节本、增产。 The experiment in machine drilling, artificial sowing and seedling transplanted by hands of single season rice Shanyou 63 and Zhongxian 1302~2 was conducted. The results indicated that rice yield from machine drilling without transplanting was 7593 kg per hm 2 which increased over 20.3% more than the yield of 6309kg per hm 2 by artificial transplanting. The net profit from the former was 5365 yuan per hm 2 and the later was 1099 yuan per hm 2 so the profit of 4259 yuan per hm 2 was increased. The yield from artificial sowing without transplanting was 6664kg per hm 2,which increased over 5.5% more than the yield of 6313kg per hm 2 from artificial transplanting. Thus, the technique of directly sowing rice seeds was labor saving, low cost, yield increasement and high efficiency.
