摘  要:
在砂质潮土上进行了一次性基施不同用量K2O(不施钾肥、93.75kg/hm2、187.50kg/hm2、281.25kg/hm2、375.00kg/hm2、562.50kg/hm2)试验,研究其对土壤养分含量及冬小麦产量和品质的影响。结果表明,施钾量在0.00~375.00kg/hm2的范围内,随着施钾量的增加,小麦产量和品质均呈提高的趋势,超过375.00kg/hm2时,小麦产量和籽粒品质呈下降趋势。随着施钾量的增加,土壤中的速效钾含量不断升高,其他养分含量无明显的变化。要保持土壤中速效钾平衡,达到小麦优质高产,以施钾(K2O)281.25~375.00kg/hm2为宜。

摘  要:
In order to study the effects of amount of potassium usage on sandy soil nutrient content and yield and quality of wheat,different amount of potassium(0kg/ha,93.75kg/ha,187.50kg/ha,281.25kg/ha,375.00kg/ha,562.50kg/ha)were treated in winter wheat areas.The results showed that,within the range of potassium volume between 0.00 kg/ha to 375.00kg/ha,the increasing of the amount of potassium will lead to the increasing of wheat yield and quality.When potassium amount surpassed more than 375.00kg/ha,however,wheat yield and grain quality will decline.With the increasing of the amount of potassium usage,soil available potassium increased,the other nutrients showed no significant changes.Therefore,for ensuring the balance between soil potassium and achieving high-yield,the usage of potassium(K 2O)should be limited between the 281.25kg/ha to 375.00kg/ha.
