摘要:

本研究旨在探讨玉米与花生间作对作物农艺性状、生理活性及土壤特性的影响。通过盆栽根系分隔试验,评估了间作对玉米和花生的株高、叶绿素含量、抗逆性指标(SOD和POD活性)以及土壤速效养分和酶活性的影响。结果表明,玉米花生间作影响作物的形态及生理指标。增加花生株高71.4%、相对叶绿素含量11.3%,但对其根长、根重和叶片重量无显著影响;增加玉米株高43.9%、叶片鲜重122%及根长45.6%;但对其叶片叶绿素相对含量无显著影响。玉米花生间作提高植物抗逆性,分别增加花生叶片SOD和POD活性66.7%和129%、降低根系MDA含量19.8%;分别增加玉米叶片和根系SOD活性39.9%和17.0%,降低其根系MDA含量61%。玉米花生间作改变土壤速效养分含量,降低花生土壤碱解氮79.5%,但提高土壤速效磷含量11.5%、对其土壤速效钾含量无影响;对玉米田土壤碱解氮和速效钾含量无影响,但降低土壤速效磷含量9.4%。玉米花生间作影响土壤生物学特性,增加土壤酶活性,尤其对碱性磷酸酶活性的提高幅度较大,花生和玉米田土壤碱性磷酸酶活性分别增加122%和330%;增加玉米和花生土壤微生物数量,玉米花生间作可改善土壤微环境,提高作物苗期叶片和根系生理活性。

Abstract:

In order to study the influence of maize-peanut intercropping on crop and soil characteristics, this paper sets up the root separation test of corn and peanut potted plants to study the influence of maize and peanut intercropping on crop agronomic traits, physiological activities, soil microorganisms, soil enzyme activity and soil rapid nutrients. The results showed that maize-peanut intercropping affected the morphological and physiological indexes of crops. Plant height and relative chlorophyll content of peanut were increased by 71.4% and 11.3%, but root length, root weight and leaf weight were not significantly affected. Plant height, leaf fresh weight and root length of maize were increased by 43.9%, 122% and 45.6%, respectively. But there was no significant effect on the relative content of chlorophyll. Maize-peanut intercropping improved plant stress resistance, increased SOD and POD activities of peanut leaves by 66.7% and 129%, and decreased MDA content of peanut roots by 19.8%, respectively. The activities of SOD in leaves and roots of maize were increased by 39.9% and 17.0%, respectively, while MDA content in roots decreased by 61%. Maize-peanut intercropping changed soil available nutrient content, decreased peanut soil available N by 79.5%, but increased soil available P by 11.5%, and had no effect on soil available K content. It had no effect on maize soil available N and K, but decreased soil available P by 9.4%. Maize-peanut intercropping affected soil biological characteristics and increased soil enzyme activities, especially the alkaline phosphates activity. The soil alkaline phosphates activity in peanut and maize fields increased by 122% and 330%, respectively. The Maize-peanut intercropping could improve soil microenvironment and physiological activities of leaves and roots in seedling stage.
