Effects of Organic Fertilizer Application Rate on Agronomic Traits and Yield of Rapeseed Under Rice-oilseed Rape Rotation Model in Erhai Lake Basin
摘要
Abstract
This study aimed to investigate the impact of different organic fertilizer applications on the economic traits and yield of crops under the rice-oilseed rape rotation model,exploring the optimal rate of organic fertilizer application and providing scientific basis for application in oilseed rape cultivation.Field trials were conducted from 2019 to 2022 at the Heng'an Agricultural and Forestry Professional Cooperative in Yinqiao Town,Dali City.Rice cultivation was treated with 7500 kg/hm2 of solid organic fertilizer and 600 kg/hm2 of liquid organic fertilizer.Four treatments of organic fertilizer applications for oilseed rape cultivation were set up,including no fertilizer(A),7500 kg/hm2 of solid organic fertilizer+1890 kg/hm2 of liquid organic fertilizer(B),15000 kg/hm2 of solid organic fertilizer+1890 kg/hm2 of liquid organic fertilizer(C),22500 kg/hm2 of solid organic fertilizer+1890 kg/hm2 of liquid organic fertilizer(D).The results showed that:(1)the average values of the main economic traits of oilseed rape increased with the quantity of organic fertilizer application.(2)Over two years,the average yields of oilseed rape in treatments A to D was 922.40,2352.35,2830.5 and 3237.40 kg/hm2,respectively,demonstrating that oilseed rape yield also increased with the application of organic fertilizer.This study concluded that increasing application of organic fertilizer enhanced oilseed rape yield and economic traits.Considering the factors such as yield and cost,the optimal application rate of organic fertilizer was proposed as followed:15000 kg/hm2 of solid organic fertilizer and 1890 kg/hm2 of liquid organic fertilizer.This study provides a scientific guidance and theoretical basis for organic fertilizer application in cultivation of oilseed rape.关键词
