摘  要:
为了探明干旱地区玉米抗旱播种的有效方法,进行了不同耕作方式对旱地土壤环境和玉米产量的影响试验。结果表明,免耕探墒播种条件下,2~7cm土层土壤容重较旋耕增加了4.31%,没有达到显著水平;旋耕较免耕探墒提高了地温,但免耕探墒条件下0~20cm土壤水分含量最高;少耕处理的产量最低,为6555.38kg/hm2,免耕探墒播种的产量为6591.82kg/hm2,较旋耕降低553.36kg/hm2,减产效果没有达到显著水平。免耕探墒播种是旱地农业生产中有效的抗旱播种方法。

摘  要:
To investigate effective method of maize drought seeding in dryland,we did experiment of different tillage methods on soil surroundings and yield of maize.The result indicates:though the soil bulk density(2~7 cm)under no-tillage and detective soil moisture increased 4.31% than in rotary tillage,but it showed no significant difference,rotary tillage improved the temperature than no-tillage and detective soil moisture,but the highest soil moisture content 0 ~20 cm under no-tillage and detective soil moisture.The lowest yield of maize under minimal tillage was 6 555.38 kg/hm2 and the yield under no-tillage and detective soil moisture was 6 591.82 kg/hm2,553.36 kg/hm2 lower than in rotary tillage.The yield under no-tillage and detective soil moisture had no significant difference from that under rotary tillage.Seeding under no-tillage and detective soil moisture was an effective method of drought seeding in dryland agriculture.
