| 摘 要： | 利用西峰农业气象试验站玉米观测地段土壤水分资料（1990~2007年）和玉米产量资料，以及与之毗邻的西峰基准站气象资料，分析了观测地段土壤水分变化规律及土壤水分变化对玉米产量的影响。结果显示：土壤贮水量的变化呈二次曲线，贮水量最低值出现在8月中旬；耗水量的变化呈直线；贮水量与玉米产量相关最显著的时段在拔节到抽雄阶段，拔节～抽雄0～50cm土壤贮水量每增加10mm，产量增加180-210kg/hm2. |

| Abstract: | using the data of soil moisture of maize observation land sector in Xifeng agro-meteorological experimental station (1990 ~ 2007) and maize yield, As well as with it adjoining to meteorological data by Xifeng datum station, analyzed observed the land sector soil moisture change rule and its influence to the maize yield. The results shown that soil moisture storage change assumes the conic section, it minimum value appears in mid-August. The moisture consumption change assumes the straight line. The moisture storage are related the most remarkable time interval to joint pull out the male stage with the maize yield, joints to pull out the male 0~50cm soil moisture storage increase 10mm every time, the yield increases 180-210 kg/hm2. |
