稻鸭共育模式下养鸭密度的调控效应
Effects of duck stocking density regulation in a rice-duck co-culture system
摘要
Abstract
[Objective]This study was conducted to explore the regulatory effects of duck-raising density on rice growth and economic benefits under the rice-duck co-culture mode,identify the suitable density balancing high yield and ecological benefits,and provide references for the standardized promotion of this technology.[Method]Three duck stocking density treatments were established(T1:150 birds/hm 2,T2:300 birds/hm2,T3:450 birds/hm2),with conventional rice cultivation without ducks serving as the control(CK).Field trials measured agronomic traits of rice,fresh weight of weeds,and economic indicators,with statistical analysis conducted to determine significant differences.[Result]All rice-duck treatments outperformed the CK control.The number of effective panicles per rice plant increased by 22.6%compared to that of the CK,while weed fresh weight decreased by 94.6%.Net income per hectare reached 35 940 yuan,representing an increase of 23 220 yuan over that of the CK.[Conclusion]Duck stocking density significantly regulates the rice growth and economic benefits,with 450 ducks per hectare maximizing the overall efficiency.In practical implementation,appropriate stocking densities can be flexibly selected based on the production objectives.关键词
