Abstract: Effects of cultivation pattern on yield and water use efficiency and production cost of rice Lvhanyihao was studied by use of random complete block in open field.The result showed that yield of rice cultivated in plastic film mulching increased by 6.5% and significantly higher than that in water(as acheck) under the soame conditions of seeding and transplanting time.The growth period of direct sowing shortened 15～25 days and the yield decrease 9.2% compared with control. Lvhanyihao had higher water use efficiency and needed less irrigated water in drying cultivation pattern. Of all the treatments, production efficiency and water use rate in film mulching drying cultivation were both highest and were 8.3 and 3.2 times of the control, respectively. The highest net income was obtained in drying boardcast sowing followed by less water drilling, unarmed transplanting, plastic film mulching and straw mulching. It is suggested that Lvhanyihao could be produced by broadcast sowing and irrigating little water in regions of lack of water and labor.
