在海南三亚,以超级杂交水稻组合两优培九和两优0293为材料,设置了窄垄、中垄、宽垄3个不同垄栽处理,以平作为对照研究了不同栽培模式对水稻产量、苗穗、根系、剑叶的影响。结果表明,总体上产量及各项性状指标与对照相比无明显优势,与起垄宽度无明显关系,而且在不同组合中表现不同。认为在海南三亚不宜推广水稻垄栽模式。
In Sanya, Hainan Province, three different ridge cultivation with narrow ridge, middle ridge and wide ridge were set up with super hybrid rice combination Liangyoupeijiu and Liangyou 0293 as materials. The effects of different cultivation modes on the yield, spikelet, Roots, the impact of the flag leaf. The results showed that the overall yield and the traits of each trait had no obvious advantage compared with the control, no significant relationship with ridge width, and different performance in different combinations. It is not appropriate to popularize rice ridge planting mode in Sanya, Hainan Province.
