不同种养模式对水稻生长和产量的影响
Effects of different farming models on growth and yield of rice
摘要
Abstract
Huamoxiang 5 rice,Wuqin 10 duck,and crayfish were used to set up four farming modes including rice-duck-crayfish large field block model(BRXD),rice-duck-crayfish unit release model(CRXD),rice-duck-crayfish"nomadic duck"model(NRXD)and rice-crayfish coculture(RX),with the traditional rice monoculture(CK)as the control.The effects of different farming models on the growth and yield formation of rice were studied to achieve the goal of high yield,high quality and high efficiency under the ecological farming mode in paddy field.The results showed that the population growth rate at different stages of rice growth and the biomass of tiller at the stage of full heading under farming models of BRXD,CRXD,and NRXD significantly increased compared with CK,with biomass of tiller increased by 20.29%,12.83%,and 11.34%,respectively.The biomass of stem and tiller under farming model of BRXD increased significantly at different stages.In terms of yield and its components,the number of pani-cles under farming models of BRXD,CRXD,and NRXD decreased,but the seed setting rate increased by an average of 7.97%.The grain number per panicle under farming models of BRXD and CRXD increased.The yield of rice under farming models of BRXD and NRXD had no decrease.It is indicated that the ecolog-ical farming of rice-duck-crayfish,especially farming models of BRXD and CRXD,can still achieve high yield while reducing inputs of fertilizer and pesticides compared with the traditional monoculture of rice.The ecological farming of rice-duck-crayfish can promote the growth and yield formation of rice.关键词
