“旱优113”在海南的种植表现

Planting Performance of“Hanyou No.113”in Hainan Province

【目的】培育节水抗旱稻新品种,增强水稻在干旱条件下的高产和稳产性,促进水稻生产可持续发展。【方法】以“旱优113”为试验品种,“特优009”为对照品种,在海南省10个地区进行试验种植,调查“旱优113”早造和晚造的全生育期、经济性状、产量表现。【结果】“旱优113”早造、晚造的全生育期分别比对照短1 d、1.6 d;早造、晚造平均穗长分别为27.0 cm、27.0 cm,平均有效穗数分别为250.5万/hm^(2)、246万/hm^(2);早造、晚造平均产量分别为8.23 t/hm^(2)、8.11 t/hm^(2),分别比对照高4.8%、6.3%,米质优,抗逆性好。【结论】“旱优113”适宜在海南省推广种植。

【Objective】To develop new varieties of water-saving and drought-resistant rice to enhance the high and stable yield of rice under drought conditions and promote the sustainable development of rice production.【Methods】With“Hanyou No.113”as the test variety and“Teyou No.009”as the control variety,the experiments were carried out in 10 areas of Hainan Province.To investigate the whole growth period,economic characters and yield performance of early and late production of“Hanyou No.113”.【Results】The whole growth period of early and late production of“Hanyou No.113”was 1 d and 1.6 d shorter than that of control.The average ear length of early and late crops was 27.0 cm and 27.0 cm,respectively.The average yield of early cropping and late cropping were 8.23 t/hm^(2) and 8.11 t/hm^(2),respectively,which were 4.8%and 6.3%higher than that of the control,respectively,with desirable quality and stress resistance.【Conclusion】“Hanyou No.113”is suitable for popularization and planting in Hainan Province.
