| 摘 要： | 水是稻田养鱼的一个限制因子,研究稻鱼系统蓄水深度具有重要意义。开展了稻鱼共生系统不同蓄水深度对水稻和田鱼影响的田间试验。结果表明,在水源不足的热带和亚热带山区,只要能够保证水稻生育期稻田水深达到10 cm就能开展稻田养鱼,田鱼生长早期不受影响;水源充足的地区,稻田水深25 cm时,水稻产量不会受到明显影响。

| Abstract: | The field water depth is a critical factor to affect rice and fish yield in rice-fish ecosystem.The results from studying the effect of different irrigation water depth on growth of rice and fish in rice-fish ecosystem showed that fish could be bred in the rice field with 10 cm water depth during the whole rice growth period in the tropical and subtropical mountain areas and fish growth was not affected at the early stage,the rice yield planted in the rice field with 25 cm water depth was not affected signi... |
