| Abstract: | This paper discusses the status of agricultural resources and the existing problems,current situation of grain production and productive potentiality.Furthermore,some basic ideas on the improvement of grain production potential are concluded,including positively develops the zoning rotation practice system and improve multiple crop index;pay attention to the improvement of internal productivity of grain crops populationy,increase science and technology innovation,strengthen the supporting effect of agriculture science and technology to grain production;reduce the no-target output in agricultural runoffs of the sloping farmland;pay attention to the construction of quality of arable land,improve the security of cultivated land of grain production ability. |
