摘要
根据不同类型区农作物生产条件,分析了旱地农作物生产潜势及生态适应性,对8个有代表性县的农作物最大生产潜力进行了估算,并对阻碍农作物最大生产潜力发挥的限制因素进行了讨论。在此基础上,提出了不同类型区农作物增产的主要途径和措施。
According to the agricultural conditions in different regions,the productive potentials and e-cological adaptability of crops in arid farmland were analysed. The largest productive potentials ofcrops in eight typical counties have been estimated. The limitative factors for productive forceshave been determined. Finally, the authors put forward the major ways and measurements for in-creasing-yield in different regions.
