中文摘要: 针对东北雨养区中心支轴式喷灌机的发展,和对与之配套的耕作与农艺管理措施的迫切需求,以玉米为研究对象,分别在2014年及2015年在东北西部内蒙古通辽地区开展了中心支轴式喷灌机喷灌条件下鱼鳞坑、深松及深松 +鱼鳞坑耕作等配套耕作措施对土壤物理性质及玉米生长影响的田间试验研究。结果表明:与传统免耕相比,不同耕作措施均能有效降低040cm深度的土壤容重,提高土壤孔隙度和土壤饱和导水率,从而改善了土壤结构;虽然深松、深松+鱼鳞坑两个处理之间玉米的产量没有显著差异,但是采用深松、深松+鱼鳞坑耕作措施可以增加玉米的茎粗和株高,并提高穗部干物质积累速率、穗干重比例和百粒重,有利于玉米的增产。
英文摘要: Under the background of global climate change,the drought disaster in rain-fed district becomes more serious,which restricts the local maize′s production.The rich land resource fails to give full exertion, so water saving irrigation technology is well developed in the Northeast China these years.For the sprinkler′s development and its demand for matching tillage and agronomic management in the rain-fed district of Northeast China,with maize as the research object,a field experiment with four tillage(no tillage,subsoiling-tillage, scale-like pit tillage,subsoiling plus scale-like pit tillage)was conducted to investigate the tillage effects on soil characteristic and maize growth in 2014 and 2015.The main results show as follows:three different tillage patterns can improve the soil structure by reducing the bulk density and improving the soil porosity and infiltration rate of the surface soil(040 cm);Though the difference of yield between the subsoiling tillage and the subsoiling plus scale-like pit tillage are not significant,the subsoiling tillage and subsoiling plus scale-like pit tillage can improve the height,stem diameter,100 seed weight,corn ear dry weight and the dry matter accumulation rate in the stage of maize growth,which is beneficial to increase the yield;Compared with the conventional no tillage,the two tillage treatment can increase the yield of maize significantly.
