为了探究水稻垄作栽培和稻-鱼-鸡共生模式的结合对水稻茎秆倒伏、穗部性状及产量的影响,本文通过设计常规水稻垄作栽培(CK)、水稻垄作养鱼(RF)、水稻垄作养鸡(RC)和水稻垄作养鸡养鱼(RFC)的田间对比试验,研究垄作稻-鱼-鸡共生模式下水稻茎秆倒伏、穗部性状和实际产量的变化。结果表明: 2年中4个处理的水稻株高、株鲜重、重心高度和节间长的均值整体无显著性差异。与CK处理相比, RFC和RC处理水稻茎秆节间外径、节间壁厚、穗长和穗鲜重虽呈增加趋势,但均值整体也无显著性差异;水稻产量也保持稳定。 RF处理水稻茎秆节间外径、壁厚、穗长和穗鲜重均呈降低趋势,且2019年穗鲜重达显著降低(P

Based on previous studies of ridge cultivation, rice-fish co-culture, and rice-chicken co-culture, we proposed an integrated technology of ridge cultivation of rice combined with fish and chicken co-culture (RFC), and observed its' obvious yield and economic benefits. The objective of this study was to determine the effects of RFC on stem lodging resistance, panicle traits, and grain yield in rice. Field experiments were conducted in 2018 and 2019 to compare the stem lodging resistance characteristics, panicle traits, and rice yield when grown ...
