通辽地区农业生产潜力分析

Analysis on the agricultural natural potential productivity in Tongliao city

对通辽市农业区主要粮食作物及苜蓿的生产潜力及增产潜力进行了分析。结果表明通辽地区的光合、光温潜力较大,降水生产潜力较低,热量条件是限制通辽地区粮食增产的主要非可控因素;土壤生产潜力较低,其主要限制因素是土壤有机质含量低。通辽市不同地区、不同作物间增产潜力存在明显差异。

On the basis of analyzing the potential productivity and latent capacity in increasing yield of the main cereal crops and alfalfa in Tongliao city, it has shown that the photosynthetic, photosynthesis-temperature potential productivity is great, the potential productivity of agro-climatic resource in Tongliao is small, the temperature is the main factor that we couldn't control; the low organic matter content is the main limiting factor to low land potential productivity. It exists obvious difference in latent capacity in increasing yield in different areas and different crops.
