中文摘要	为了探索免耕/深松隔年轮耕对土壤理化性状及冬小麦产量的影响,2007年至2010年在宁南旱区采用免耕/深松/免耕、深松/免耕/深松与连年翻耕3种耕作模式,对土壤容重、团聚体、养分及小麦产量等进行了研究。结果表明:与传统耕作相比,免耕/深松/免耕和深松/免耕/深松模式显著(p<0.05)降低土壤容重,改善了土壤的孔隙状况;两种轮耕模式可显著(p<0.05)增加0~40 cm各土层2~0.25 mm水稳性团聚体的含量。3种耕作方式比较,深松/免耕/深松模式最能有效增加0~40 cm土壤有机质和0~20 cm土层全氮含量;免耕/深松/免耕和深松/免耕/深松处理较传统耕作显著增加0~40 cm土层碱解氮和有效磷含量、20~40 cm土壤速效钾含量,改善了土壤的养分状况。试验期间,免耕/深松/免耕、深松/免耕/深松模式3年平均小麦籽粒产量较传统耕作显著增加,分别增产9.59%和10.69%(p<0.05),以深松/免耕/深松处理增产效果最佳。
英文摘要	To explore effects of tillage on soil physical and chemical properties and yield of winter wheat in semi-arid South Ningxia,a 3-year field experiment was carried out from 2007 to 2010.The experiment was designed to have three tillage patterns,i.e.non-tillage(NT)/subsoiling(ST)/non-tillage(NT),ST/NT/ST and conventional tillage(CT) as control and soil bulk densities,aggregates,soil nutrients and yields of winter wheat of the three treatments were determined separately.Results show that compared with CT,treatments NT/ST/NT and ST/NT/ST significantly(p<0.05) decreased soil bulk density,improved soil total porosity and significantly(p<0.05) increased the amount of 2~0.25 mm water-aggregates.Treatment ST/NT/ST was the most effective in increasing soil organic matter(in 0~40 cm soil layer) and total N(0~20 cm) among the three;compared with CT,treatments NT/ST/NT and ST/NT/ST significantly(p<0.05) increased alkalyzable-N(0~40 cm),available P(0~40 cm) and available K(20~40 cm),and improved soil nutrient status.Treatments NT/ST/NT and ST/NT/ST also significantly increased wheat yield.Their three-year mean grain yield was(p<0.05) 9.59% and 10.69% higher than that of the control.Obviously,treatment ST/NT/ST is better than treatment NT/ST/NT in yield raising.
