不同水肥调控对夏玉米生化指标及产量的影响
Effects of Different Water and Fertilizer Regulation on Biochemical Indexes and Yield of Summer Maize
摘要
Abstract
To effectively solve the problems of irrational use of water and fertilizer and low efficiency of water and fertilizer utilization,there were W1(2 250 m3·hm-2)and W2(4 500 m3·hm-2)were designed for NF(conventional fertilizer),SF(slow controlled release fertilizer),MF(compound fertilizer)and F0(no fertilizer),and the effects of maize on biochemical indexes,yield composition factors and yield under different treatment combinations were studied.The results showed that scientific irrigation and fertilization conld sig-nificantly improve the NR,SOD,POD and CAT activities of summer maize,and the application of compound fertilizers to increase SOD activity in maize was superior to conventional fertilizer application and application of slow and controlled release fertilizers.Fer-tilization conld significantly increase the accumulation of dry matter in maize,and the highest yield of 11 240.40 kg·hm-2 was achieved by applying slow and controlled release fertilizer at the W2SF treatment,which was 160.94%higher than W1F0 treatment.Under the same fertilization,the summer corn yields of W2F0,W2NF,W2SF,and W2MF treatments increased by 20.31%,25.62%,29.46%,and 28.46%,respectively,compared with W1F0,W1NF,W1SF,and W1MF.In conclusion,the water-fertilizer pattern of moderately increasing irrigation combined with the application of slow and controlled release fertilizers can significantly improve the quality and yield of summer maize.关键词
