摘要
为了对川南丘陵区的节水抗旱杂交稻适栽类型进行了研究,通过邻田对比调查节水抗旱杂交稻与四川主栽普通杂交稻在冲沟田及坡塝田的产量差异。结果表明,节水抗旱杂交稻旱‘优113号’、‘旱优715号’在冲沟田种植比四川主栽普通杂交稻减产2.65%～7.23%,在坡塝田种植增产17.57%。在严重干旱条件下的减灾效果十分明显。因此,节水抗旱杂交稻更适合在丘陵稻区坡塝田种植,在坡塝田有效穗增加是增产的主要原因。
The yield difference between water-saving drought-resistant hybrid rice and Sichuan major hybrid rice were compared in the gully field and the slope field by comparison with adjacent field investigation to study the suitable type of water-saving drought-resistant hybrid rice in the southem Sichuan hilly area..The results showed that,in the southern Sichuan hills,compared with major hybrid rice varieties in Sichuan,the yield of＇Hanyou 113＇ and ＇Hanyou715＇ of water-saving and drought-resistance hybrid rice decreased by 2.65 %-7.23 % in gully condition and increased 17.57 % in the slope field.Under the condition of the severe drought disaster,mitigation effect was very obvious.The conclusions was drawn that water-saving drought-resistant hybrid rice was suitable to the hill slope field cultivation and increase of effective panicle number was the main reason of yield increase in slope field.
