秸秆还田配施氮肥对绿豆生长和产量的影响
Effects of straw returning combined with nitrogen fertilization on growth and yield of mung bean
摘要
Abstract
[Objective]To clarify the effects of straw returning combined with nitrogen fertilization on growth and yield of mung bean,and to provide a reference for the rational utilization of straw resources and scientific nitrogen application in mung bean cultivation.[Methods]The experiment was conducted at the experimental farm of the Inner Mongolia Academy of Agricultural&Animal Husbandry Sciences using the mung bean variety Kelv No.1 as the test material.A split-plot design with two factors was adopted,with maize straw returning(ST)and no straw returning(NST)as the main plots,and four nitrogen application levels-0(N0),45(N45),90(N90),and 135(N135)kg/hm2-as subplots,resulting in a total of eight treatment combinations.The effects of different treatments on emergence rate,growth indicators,root system architecture,dry matter weight of aboveground organs,and yield of mung bean were analyzed.[Results]Under different treatments,the mung bean emergence rate,plant height,stem height,stem diameter,total root length,total root surface area,total root volume,leaf dry matter weight,stem dry matter weight,pod dry matter weight,grain dry matter weight,and yield were consistently as follows:ST+N90>ST+N135>ST+N45>NST+N90>NST+N135>NST+N45>ST+N0>NST+N0.Specifically,compared with the ST+N0 treatment,the ST+N90 treatment increased by 4.36％,8.06％,4.23％,14.29％,42.05％,29.75％,23.45％,21.10％,17.95％,38.48％,27.03％and 17.80％,respectively;compared with the NST+N0 treatment,the NST+N90 treatment increased by 3.31％,5.88％,3.68％,9.75％,29.77％,20.83％,14.84％,15.58％,13.91％,27.93％,19.20％and 17.12％,respectively.Mung bean yield showed extremely significant positive correlations with emergence rate,plant height,stem height,stem diameter,total root length,total root surface area,total root volume,leaf dry matter weight,stem dry matter weight,pod dry matter weight,and grain dry matter weight(P<0.01).[Conclusion]The maize straw returning combined with 90 kg/hm2 nitrogen fertilizer(ST+N90 treatment)can increase mung bean emergence rate,promote root growth,enhance dry matter weight of various organs,and improve yield.This treatment is a suitable nitrogen-reduction and efficiency-enhancement cultivation practice for mung bean production in central Inner Mongolia.关键词
