摘要
设置稻鸡共生(RC)、稻鸭共生(RD)和水稻单作(CK)3个处理,研究稻禽共生对水稻群体生长特性和产量形成的影响,并明确最优的稻田养禽模式,为稻田养禽的推广应用提供理论依据。结果表明,稻禽共生总体上降低了水稻株高、地上部干质量、叶面积指数和光合势,提高结实率,但对产量的影响呈现2 a相反的结果。与CK相比,2021年RC和RD处理水稻产量分别增加了9.26%和4.75%,其中RC处理达到显著水平;2022年分别降低了10.20%和15.04%,其中RC处理差异不显著。与RD处理相比,RC处理水稻叶面积指数提高,群体生长速率、光合势表现更优,产量更高。综上,稻鸡共生模式具有较高的推广价值。
Three treatments,namely rice⁃chicken symbiosis(RC),rice⁃duck symbiosis(RD),and rice monoculture(CK),were set up to study the effects of rice⁃poultry symbiosis on the growth characteristics and yield formation of rice populations,and identify the optimal rice field poultry farming mode,so as to provide a theoretical basis for the promotion and application of rice field poultry farming.The results showed that the symbiosis of rice and poultry generally reduced rice plant height,aboveground dry weight,leaf area index and photosynthetic potential,and increased seed setting rate,but the impact on yield showed opposite results between two years.Compared with CK,the rice yield under RC and RD treatments increased by 9.26%and 4.75%respectively in 2021 with significant difference in RC treatment,decreased by 10.20%and 15.04%respectively in 2022 with no significant difference in RC treatment.Compared with RD treatment,RC treatment improved the leaf area index,population growth rate,photosynthetic potential and yield of rice.In summary,the rice⁃chicken symbiosis model has high promotion value.
