Path Analysis on the Large-scale Yield Increase of Soybeans in Qiqihar City
摘要
Abstract
The large-scale increase in soybean yield per unit area is a major issue for relieving China's food import pressure,improving the self-sufficiency rate of edible oil and protein feed,and ensuring national food security.In order to clarify the influencing factors of soybean yield per unit area in northeast China,explore typical practices for yield improvement,summarize models for further promotion,from August 25th to 29th,in Qiqihar City,Heilongjiang Province,a main soybean producing area,we investigated 27 person-time including local grain farmers,technicians,cooperative leaders,and relevant experts from the Academy of Agricultural Sciences through on-site observation and discussion interviews.Based on the field survey of Qiqihar City,Heilongjiang Province,the main producing area of soybeans,this paper analyzes the main factors affecting the improvement of soybean yield per unit area in northeast China.The results show that technologies such as integrated water and fertilizer management,large ridge dense planting,and biological agents inoculation have significant effects on breaking through the key bottleneck of large-scale soybean yield improvement and increasing yield per unit area.At the same time,it is found that the further improvement of large-scale soybean yield per unit area is faced with challenges such as the risk of extreme climate change,the yield per unit area entering a plateau period,the low efficiency of farmers growing soybeans,and farmers'conservative mindset of maintaining production rather than pursuing development.The study points out that it is necessary to tackle key scientific and technological problems to strengthen farmland facilities to cope with the periodic fluctuations in yield per unit area caused by natural disasters,rely on major technological innovations to promote black soil protection and break through the soybean yield plateau period,strengthen meteorological monitoring and early warning to achieve the leap from relying on the weather to working with knowledge of the weather,targeted innovations in the production system to promote large-scale management and improve the income of farmers growing soybeans,and promote the large-scale improvement of soybean yield per unit area through multiple measures of policy guidance and scientific and technological innovation.关键词
