Abstract

Abstract:

【Objective】In order to provide a theoretical basis for the selection of simplified production techniques, to realize the fertilizer reduction and increasing efficiency, saving cost and increasing income in Huang-Huai-Hai region, the effects of one-off fertilization on the yield, nitrogen use efficiency and economic effects of summer maize were studied.【Method】The field experiments of one-off application of controlled release nitrogen fertilizer on maize was carried out in 8 test points selecting from Hebei, Henan and Shandong province from 2015 to 2016, the economic effects of one-off fertilization on summer maize in Huang-Huai-Hai region were studied to verify the feasibility of the nitrogen reduction of one-off fertilization. the one-off fertilization treatments of CRFA (the amount of nitrogen input in controlled release nitrogen fertilizer was equivalent to OPT treatment), CRFA80%N, CRFB80%N and CRFC80%N (with the amount of nitrogen input in controlled release nitrogen fertilizer was 20% reduction) were set to compare with the multiple application of common nitrogen fertilizer (FP treatment and OPT treatment).【Result】(1) Compared with FP treatment, the one-off fertilization had no significant effect on plant height, ear characters, and the average value of 2 years’ yield of summer maize in Huang-Huai-Hai region, even though the N agronomic efficiency (NAE) and N recovery efficiency (NER) had been increased; However, partial factor productivity from applied N (PFPN) of one-off reduced fertilization were significantly improved more than 33.85%. In addition, there were 8.15, 50.65, 50.65 and 50.65 kg N·hm^-2 saving of the CRFA, CRFA80%N, CRFB80%N and CRFC80%N treatment in one maize season, respectively. one-off fertilization increased net income more than 927.40 yuan·hm^-2. (2) In addition to the CRFA treatment, the NO₃^--N contents of the remaining treatments of one-off fertilization were significantly lower than FP, and 0-90 cm soil NO₃^--N content of the treatments of one-off reduced fertilization (CRFA80 % N, CRFB80% N, CRFC80% N) were significantly lower than OPT (P<0.05). 【Conclusion】 one-off fertilization realized the simplified fertilization of summer maize in Huang-Huai-Hai region, increased the nitrogen use efficiency, which could realize the fertilizer reduction and ensuring stable yield at the same time. It was recommended that the fertilization mode of controlled released nitrogen with reducing 20% should be applied to the summer maize production in Huang-Huai-Hai region.

Key words: Huang-Huai-Hai region, summer maize, one-off fertilization, fertilizer reduction, efficiency increasing
