中文摘要:根据杂交稻的种植技术要求,降低播种量,培育壮秧,实现少本稀植,是发挥杂交稻机插秧增产潜力的关键。该文以超级杂交稻两优培九为材料,比较精量条播和撒播育秧的机插秧秧苗素质及机插效果。结果表明:与撒播相比,条播种子分布比较均匀,秧苗成毯效果好,且秧苗素质好。条播育秧能降低机插的漏秧率和伤秧率,并提高插秧的整齐度,每丛1~2株的比例提高。研究表明在稀播种量条件下,通过条播和调整秧爪取秧规格可有效降低漏秧率,提高机插效果。

Abstract:According to the agronomic requirements for transplanting technology for the super hybrid rice, reducing seeding rate and cultivating strong seedlings and realizing fewer seedling and bigger space planting are the key to increase yield potential in mechanized transplanting of hybrid rice. In this paper, rice seedling quality and effectiveness of mechanized transplanting of precision seed drilling and sowing were studied with super hybrid rice Liangyoupeijiu. The results showed that precision seed drilling had more uniform seed distribution, better seedling mat-formed effect and seedling quality in comparison with seed broadcasting. Precision seed drilling could reduce the rate of no-seedling in hill and the rate of injured-seedling, and improve the uniformity of seedling. The percent of one and two seedling in hill after mechanized transplanting was increased. Research shows that precision seed drilling can effectively reduce the rate of no seedling in hill and improve seedling quality and mechanized transplanting quality.
