摘要：

以中浙优8号、野香优3号、桂育9号、桂禾丰、Y两优1号、昌两优8号等品种为试验材料，采用宽窄行和等行距两种栽植方式，以控释肥作基肥一次性施肥，对适合稻鱼系统的水稻品种进行筛选。结果表明，Y两优1号和中浙优8号的产量高，可分别作为双季稻稻鱼系统早季中偏晚和晚熟品种种植，桂育9号生育期、株高、产量、叶面积指数各方面表现适中，可作为稻鱼系统中熟品种种植。栽植方式对各水稻品种的分蘖、株高、产量影响差异不显著；宽窄行栽植能提供更大的活动空间，适合稻鱼系统栽培模式。

Abstract:

In order to screen the rice varieties suitable for rice-fish system, a test was conducted using Zhongzheyou 8, Yexiangyou 3, Guiyu9, Guihefeng, Y liangyou 1 and Changliangyou 8 as materials, under two planting patterns. The results showed that, Y liangyou 1 and Zhongzheyou 8 had the highest yield, which could be plant as mid-late maturing variety and late maturing variety during early-cropping season, respectively. Guiyu 9 showed moderate growth period, plant height, yield and leaf area index, it could be plant as middle maturing variety for rice-fish system. There was no significant difference of different planting patterns among these rice varieties related to tillers, plant height and yield. The wide and narrow row planting could provide more activity space than equal row planting, it was suitable for rice-fish system.

Key words: rice-fish system, variety screening, wide and narrow row planting
