随着农业大型机械和新技术的推广应用,粮食产量逐年增加。玉米种植是通辽市科尔沁区主要农业产业,但近年来玉米增产幅度一直不高。基于此,从科尔沁区玉米品种、耕地、自然灾害、病虫害、田间管理、收获等角度出发,分析了玉米生产制约因... 随着农业大型机械和新技术的推广应用,粮食产量逐年增加。玉米种植是通辽市科尔沁区主要农业产业,但近年来玉米增产幅度一直不高。基于此,从科尔沁区玉米品种、耕地、自然灾害、病虫害、田间管理、收获等角度出发,分析了玉米生产制约因素,从整地、选种、播种、中耕除草、化控、浇水施肥、绿色植保、机械收获、果穗储存、灾害评估和灾后应对措施等方面提出了具体增产措施。 展开更多

Based on an analysis of the status of biomass energy sources worldwide including China, this paper concludes that the development of the biomass energy industry in China is limited by factors asfollows:food security; lack of understanding of domestic sources; the deficiency of the policy environment; and environmental protection. There are also other challenges such as: low overall level of industry development; not having yet established a complete biomass energy industry system; high production costs; weak market competition; lack of investment in research and technology; low level of market admittance threshold; and disorder of industry development. Therefore, proposed policies aimed at promoting the healthy and rapid development of the biomass energy industry are as follows: improving the policy and regulatory system to enable the biomass energy industry to develop; greater evaluation of biomass energy material resources; accelerating the development of biomass energy conversion and use technologies; establishing the demonstration bases of biomass energy industry. 展开更多
