Study on Rice Cultivation Technique

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.
