摘　　要：为了明确适宜水稻品种伍两优华占的栽培方式,对其在人工移栽和人工直播2种不同种植方式下的农艺性状以及产量进行了比较研究。结果表明:人工直播方式每穗总粒数和实粒数虽然低于人工移栽方式,但分蘖率更强,结实率和有效穗数也明显高于人工移栽方式;无论是理论产量还是实收产量,均高于人工移栽方式。从综合效益来看,与人工移栽方式相比,人工直播方式节省了人工和育苗成本,劳动强度降低,生育进程显著提前,能更大程度地提高伍两优华占的种植效益。In order to clarify the suitable cultivation method of rice variety Wuliangyou Huazhan,the agronomic characters and yield of Wuliangyou Huazhan were compared and studied under two different planting methods of artificial transplanting and artificial direct seeding.The results showed that although the total number of grains per panicle and the number of filled grains per panicle by artificial direct seeding method were lower than those by artificial transplanting method,the tillering rate by artificial direct seeding method was stronger,and the seed setting rate and effective panicle number were also significantly higher than those by artificial transplanting method.Both the theoretical yield and effective yield by artificial direct seeding method were higher than those by artificial transplanting method.From the perspective of comprehensive benefits,compared with the artificial transplanting method,the artificial direct seeding method saved the cost of labor and seedling cultivation,reduced the labor intensity,and significantly advanced the growth process,which could improve the planting benefits of Wuliangyou Huazhan to a greater extent.
