杂交稻“两优616”种植密度试验

Planting density test of hybrid rice “Liangyou 616”

为了探索杂交水稻品种"两优616"的合理种植密度,进行每667 m2插0.8万丛、1.0万丛、1.2万丛、1.4万丛、1.6万丛等5种不同插植密度试验,结果表明:每667 m2插1.2万丛处理产量最高,与每667 m2插0.8万丛处理的产量差异达极显著水平。

A test of hybrid rice ＂Liangyou 616＂ with 5 planting densities, i.e. 8000 hills, 10000 hills, 12000 hills, 14000 hills and 16000 hills per 667 m2 was carried out, in order to probe its appropriate planting density. The results showed that the highest yield of ＂Liangyou 616＂ was obtained when planting density was 12000 hills per 667 m2, to compare with that of 8000 hills per 667 m2, the difference reached very significant level.
