中文摘要	测定深耕区和免耕区玉米的保水力、电导率以及根的长度与数量,通过对比试验研究了不同栽培方式对玉米抗旱性的影响。结果表明,玉米含水量免耕区下降了350.91%,深耕区下降了467.8%;玉米的拐点温度免耕区为65℃,深耕区为55℃,所以免耕区玉米抗旱性好。免耕的地块根扎得深,而且发根数多。免耕不仅能够提早玉米的收获期而且还能够提高玉米的抗旱性,这对于干旱地区和山区玉米的栽培技术有着一定的启发。
英文摘要	In comparing test,the water-holding capacity,conductivity and the length and amount of root in maize in deep tillage area and zero tillage area were determined to study the effect of different cultivation modes on drought resistance of maize.It was found that the water content in maize in zero tillage area decreased by 350.91% and that in deep tillage area decreased by 467.8%.The inflection point temperature in maize in zero tillage area was 65℃ and that in deep tillage area was 55℃.Therefore,the maize in zero tillage area had good drought resistance,with more roots that were taken in deep layer.Zero tillage could not only harvest ahead but also increase drought resistance of maize.
