同垄种植对玉米||花生土壤有效磷分布特征和作物磷吸收利用的影响
Effects of Co-Ridge Planting on the Distribution Characteristics of Soil Available Phosphorus and the Absorption and Utilization of Phosphorus by Crops in Maize||Peanut
摘要
Abstract
[Objective]Co-ridge planting can further enhance the yield advantage of maize(Zea mays L.)and peanut(Arachis hypogaea L.)intercropping(maize||peanut).This study aimed to explore the distribution characteristics of available phosphorus in maize||peanut soil and the characteristics of phosphorus absorption and utilization in crops under the co-ridge planting,which could provide theoretical and technical basis for sustainable high-yield cultivation of maize||peanut.[Method]The experiment was conducted in the farm of Henan University of Science and Technology from 2023 to 2024,using a field randomized block experiment.Under the conditions of no phosphorus(P0)and 180 kg P2O5·hm-2(P180),the effects of co-ridge planting of maize and peanut intercropping(RIC)on the distribution characteristics of soil available phosphorus in 0-60 cm soil layer as well as the absorption and utilization of phosphorus by crops in maize||peanut were studied with flat planting of maize and peanut intercropping(FIC)as the control.[Result]In the horizontal direction,the distribution of soil available phosphorus in 0-60 cm soil layer under FIC treatment exhibited"(﹏)"(gentle)characteristics,while under RIC treatment,it showed"︹"(ridge)characteristics,under P180 the"low-high-low""︹"(ridge)characteristics was more prominent.Compared with FIC,RIC was beneficial to increase the soil available phosphorus content in the 0-40 cm soil layer within the planting unit,which significantly increased by 18.38％-21.29％under P180.Compared with FIC,RIC alleviated the interspecific phosphorus nutrition competition,increased the phosphorus content of intercropping maize and peanut,significantly increased the phosphorus accumulation,and promoted the phosphorus distribution to maize grain and peanut seed.Compared with FIC,RIC significantly increased the phosphorus absorption and yield of intercropping maize,intercropping peanut,and intercropping system,within the increase range of phosphorus absorption being 18.83％-32.62％,24.08％-41.78％and 21.06％-37.14％,respectively(P<0.05).Compared with P0,P180 could further increase soil available phosphorus content and phosphorus content in maize and peanut,promote phosphorus absorption in intercropping system,and significantly increase maize and peanut yield and intercropping advantage.[Conclusion]The co-ridge planting could further improve the yield advantage of maize||peanut compared with flat planting.The key lied in the fact that it improved the available phosphorus distribution in 0-60 cm soil and increased the available phosphorus content in the 0-40 cm soil layer of the planting unit,alleviated the interspecific phosphorus nutrition competition,and promoted the absorption of phosphorus in maize and peanut and its distribution to seed.Phosphorus application had a significant positive regulation effect.关键词
