中文摘要	试验研究了科尔沁沙地坨沼区坨子地和甸子地在不同耕作方式(传统、防护林保护)、不同耕作年限下的土壤理化性质动态变化。结果表明:保护性耕作对土壤容重、土壤机械组成影响较大,与CK2相比,坨子地保护性耕作T4、T5的耕层土壤容重分别降低了0.16,0.21g/cm3;2~0.02mm的颗粒含量分别降低了27.99%,40.59%;与CK1相比,甸子地保护性耕作D3、D4的耕层土壤容重分别降低了0.21,0.29g/cm3;2~0.02mm的颗粒含量分别降低了42.85%,55.59%。且保护性耕作土壤容重和2~0.02mm的颗粒含量均低于传统耕作。保护性耕作能增加土壤养分含量,与CK2相比,坨子地保护性耕作T4、T5的耕层有机质含量分别增加了12.69,18.65g/kg;碱解氮含量分别增加了7.7,15.7mg/kg;速效磷含量分别增加了15.27,27.06mg/kg;速效钾含量分别增加了40.19,46.58mg/kg;与CK1相比,甸子地保护性耕作D3、D4的耕层有机质含量分别增加了19.77,22.83g/kg;碱解氮含量增加了28.35,25.55mg/kg;速效磷含量分别增加了27.36,38.22mg/kg;速效钾含量分别增加了19.3,81.5mg/kg。差异均达极显著水平。保护性耕作的有机质、碱解氮、速效磷、速效钾含量均高于传统耕作。
英文摘要	The dynamic changes of soil physical and chemical properties were studied under different tillage methods(tradition,conservation of protection forest)and different tillage years on dune land and meadow of Khorchin.The results showed as follows: Conservation tillage had significant effects on soil bulk destiny and mechanical composition.Comparing with CK2,at the plough layer of T4,T5 under conservation tillage on sandy land,soil bulk density was respectively decreased by 0.16,0.21 g/cm3;2~0.02 mm of soil particles was decreased by 27.99% and 40.59%;comparing with CK1,at the plough layer of conservation tillage D3,D4 on meadow,soil bulk density was respectively decreased by 0.21,0.29 g/cm3;2~0.02 mm of soil particles was respectively decreased by 42.85% and 55.59%.These indicators were lower than traditional tillage.Conservation tillage could improve soil nutrition content.Comparing with CK2,at the plough layer of conservation tillage T4,T5 on dune land,the content of organic matter was increased by 12.69,18.65 g/kg;alkali solution nitrogen was increased by 7.7,15.7 mg/kg;available phosphorus was increased by 15.27,27.06 mg/kg;available potassium was increased by 40.19,46.58 mg/kg,respectively.Comparing with CK1,at the plough layer of conservation tillage D3,D4 on meadow land,the content of organic matter was increased by 19.77,22.83 g/kg;alkali solution nitrogen was increased by 28.35,25.55 mg/kg;available phosphorus was increased by 27.36,38.22 mg/kg;available potassium was increased by 19.3,81.5 mg/kg,respectively.The differences had reached extremely significant levels.The content of organic matter,alkali solution nitrogen,available phosphorus and available potassium in conservation tillage was higher than those of traditional tillage.
