Economic Benefit Analysis Of Aconitum Carmichaelii Debeaux Planting Technology In Jiangyou

It is of great significance to clarify the main influencing factors of Aconitum carmichaelii Debeaux planting benefit,and the economic benefit of the key technology of Aconitum carmichaelii Debeaux planting for promoting the development of genuine Aconitum carmichaelii Debeaux industry and making relevant policies in China.By means of literature review,field investigation,questionnaire survey,and the field experiment conduction,this study used the methods of statistical analysis,comparative analysis,and econometric analysis,to make a in-depth analysis for the existing problems of Aconitum carmichaelii Debeaux planting and the economic benefits of the key techniques.The results show that:1.The development of genuine Aconitum carmichaelii Debeaux industry is facing severe challenges in Jiangyou.Aconitum carmichaelii Debeaux industry has a good genuine,brand,industrial base and scientific and technological advantages.However,it's also has numerous obvious deficiencies,such as the lack of standard technologies,high production cost,and unstable market.Currently,the development of the Aconitum carmichaelii Debeaux industry is facing good political and market opportunities.However,quality safety,market expansion and brand maintenance are still the long-term challenges for the future development of Aconitum carmichaelii Debeaux industry in Jiangyou.2.The cost of Aconitum carmichaelii Debeaux planting was high and the profit was not stable in Jiangyou.The total cost of Aconitum carmichaelii Debeaux planting was very high and the variation range between the studied years was large,the average total cost per 667 m~2 of Aconitum carmichaelii Debeaux planting from 2016 to 2018 was 9 305.12 yuan.The cost of labor input,root seed,fertilizer and pesticide was the main factor affecting the total cost.The net income of the Aconitum carmichaelii Debeaux planting was unstable and the difference between the studied years and between the farmers was great.The average net income per 667m~2 of Aconitum carmichaelii Debeaux planting from 2016 to 2018 was 5 829.24 yuan.The yield,price and family labor force had a significant positive influence on the net income,while the total cost had a significant negative influence on the net income.3.Optimizing the key planting techniques had great potential to improve the yield and profit of Aconitum carmichaelii Debeaux.From the perspective of soil improvement,the yield of aconite could be significantly increased by 3197.90 kg/hm~2(32.06%),when applying quicklime.And the net profit has been increased by 89 900 yuan/hm~2.From the perspective of sowing time optimization,the yield of aconite was the highest by the sowing it 15 days later,which was 2671.58 kg/hm~2 and 986.15 kg/hm~2 higher than that of normal sowing and sowing15 days earlier respectively.From the perspective of optimizing fertilizer management,the yield of aconite and the economic benefit index first increased and then decreased with the increase of the amount of nitrogen and phosphorus fertilizer,and increased with the increase of potassium fertilizer rate.The yield increase contributed by increasing phosphate fertilizer was limited and high application of phosphate fertilizer would cause a significant reduction in aconite yield.The impact of root pruning times on aconite yield was significant,One-time root pruning had higher profit,output-input ratio,cost-return ratio and labor productivity than no root pruning or double root pruning.It is suggested that the research and application of high-yield and high quality Aconitum carmichaelii Debeaux varieties should be strengthened.Strategies on optimizing the cultivating technologies,establishing the standardized breeding base,improving the mechanization,constructing the trade system,and enhancing the benefit from“Jiangyou”brand also should be explored to promote the development of the Aconitum carmichaelii Debeaux industry.
