辽河平原棕壤区绿肥引入对玉米产量和土壤水分的影响研究
Effects of Green Manure Introduction on Maize Yield and Soil Water Content in the Brown Soil Region of the Liaohe Plain
摘要
Abstract
To address the prominent problems in the brown soil region of the Liaohe Plain,such as monoton-ous cropping patterns,low comprehensive soil fertility,and difficulties in improving maize productivity,this study investigated the effects of introducing green manure on maize production and soil water content,and screened suitable maize/green manure intercropping systems for the region.The aim was to provide a theoreti-cal basis and technical support for green,high-yielding,and efficient maize cultivation in the area.A field ex-periment was conducted with six green manure species intercropped with maize:Astragalus adsurgens,Vicia villosa,Vicia sativa,Melilotus officinalis,Milk vetch,and Alfalfa.Two maize monoculture patterns,i.e.,double row planting with one space and equal row spacing,were set as controls.Soil water content,crop dry matter accumulation,and yield were measured.The results showed no significant differences in maize yield a-mong all treatments,indicating that introducing green manure into the field could sustain normal growth and development of maize.Soil water content generally exhibited a trend of decreasing first,then increasing,and decreasing again with increasing soil profile depth across all treatments.Green manure crops could maintain soil water content to a certain extent.Considering the growth and development performance of different green manure species,Melilotus officinalis,Vicia villosa,and Alfalfa showed relatively obvious advantages and good adaptability under intercropping conditions.These three species can be recommended as suitable green manure candidates for intercropping with maize in the brown soil region of the Liaohe Plain.关键词
