中文摘要：

在池栽模拟大田轮作条件下,通过向土壤中一次性施入大量树脂控释肥残膜,探讨长期施用控释肥后残留在土壤中的树脂膜壳对土壤理化性状及冬小麦、夏玉米生长的影响。结果表明：短时期内,控释肥树脂残膜量在90～360g/m2时,残膜对粉壤土和砂壤土的容重、总孔隙度以及pH和EC等理化性状不会造成影响;残膜对小麦叶绿素含量和根系活力均未表现出现显著性影响;控释肥树脂残膜用量在90～360g/m2范围内时,冬小麦和夏玉米籽粒的粗蛋白、粗灰分、还原型Vc等主要品质指标以及产量均无显著性变化,其籽粒中全氮、全磷、全钾以及中微量元素含量也无显著性变化,但砂壤土中的夏玉米籽粒淀粉含量显著增加,残膜施入量为90,180,360g/m2时,淀粉含量分别相对增加23.83%,41.73%,23.17%。

英文摘要：

A pool-simulation field rotation experiment was conducted to assess the impacts of CRF resin residual coating on properties of soil and growth of winter wheat and summer corn after long-term using of CRF in soil.The results showed that the soil bulk density,total porosity,pH and EC of silt and sandy soil could not be reflected significantly when the residual coating was ranged from 90 g/m2 to 360 g/m2 in the soil.And the influences of applied CRF resin residual coating on the content of chlorophyll and root activity of winter wheat were not evident.In addition,the crude protein,crude ash,Vc content,yield and the content of the major mineral elements,such as N,P,K in the grain of winter wheat and summer corn were not affected by the application of CRF resin residual coating within the range of 90~360 g/m2.However,when the applied dosage was 90,180,360 g/m2,the starch content of summer corn in loamy sand soil was increased by 23.83%,41.73% and 23.17% compared to the no residual coating treatment,respectively.
