Effects of dense planting drip irrigation technology on maize root system
Maize varieties Zhengdan 958,Anke 985,and Huangjinliang MY73 were used as materials,the effects of different planting density(67 500,82 500,90 000,97 500,and 105 000 plants/hm2)on maize root growth under drip irri-gation and conventional fertilization conditions were studied.The results showed that with the increase of corn planting density,the dry weight of corn roots,aerial roots,and subterranean roots all showed a decreasing trend.The effects of dif-ferent fertilization methods on the growth of maize underground roots vary,and drip irrigation fertilization technology could promote maize root growth.The root system characteristics of variety Huangjinliang MY73 were relatively good.Planting density of 67 500 plants/hm2 under drip irrigation and fertilization conditions could help promote the growth and development of maize roots.
