Abstract

Abstract:

【Objective】This study aimed to evaluate one-off application effect of controlled release nitrogen mixed with phosphorus potassium and other nutrients on the winter wheat to realize fertilizer reduction, efficiency and cost increase etc., which provided reference of scientific techniques to the simplified production.【Method】In 2011-2012, 2012-2013, 2013-2014, thirty-one experiments of one-off application controlled release nitrogen fertilizer with wheat were carried out in different ecological areas of Huang-Huai-Hai east region to analyze the yield and nutrient efficiency, cost increase etc., and the treatments included CRFa (the equal N input with OPT treatment), 80%CRFa and 80%CRFb (the amount of nitrogen input in controlled release nitrogen fertilizer was 20% reduction compared with the multiple application of common nitrogen fertilizer (OPT treatment)). 【Result】The one-time application of controlled-release nitrogen fertilizer on winter wheat showed stable or small yield increasing trend. Compared with common nitrogen fertilizer, the average yield increased by 2.6% in the three years, and the number of experiment point for increasing production was 83.9% in the whole experiment. The proportion of experiment point for increasing production in two kinds of controlled-release nitrogen fertilizer decreased significantly, and the yield effect in biodegradable controlled-release fertilizer a was better than that of organic resin coated controlled-release fertilizer b; The yield effect of 4 fertilization patterns in sandy, loamy and clay soil texture were averagely 10.7%, 17.4% to 19.7%, respectively,, and the relative yield increasing effect of CRFa treatment (compared with OPT) in sandy or loamy soil texture soil was better than that in clay soil; The relative yield effect of controlled-release nitrogen fertilizer (compared with OPT) was better in the low yield level than that of high level block. There were14.7, 59.3 and 59.3 kg N·hm^-2 saving under CRFa, 80%CRFa and 80%CRFb treatment, respectively, compared with FP treatment, and the nitrogen partial factor productivity (PFP_N) increased by 0.4, 7.32, 6.93 kg·kg^-1 under CRFa, 80%CRFa and 80%CRFb, respectively, compared with OPT, and the apparent nitrogen utilization efficiency were improved by 1.5, 8.62 and 6.21 percentage points respectively. The income of CRFa and 80%CRFa treatments increased 543.8 and 150.3 yuan·hm^-2, respectively, compared with OPT.【Conclusion】One-off application of fertilizer on winter wheat by using the controlled release fertilizer with other nutrients showed obvious advantages from the ways of yield stability, improving the nitrogen use efficiency, saving labor and cost, and increasing income compared with the FP and OPT treatments. The results of CRFa and 80%CRFa were better under the experimental conditions. We recommended that the fertilization mode of controlled released nitrogen with reducing 20% nitrogen be applied to the winter wheat production in Huang-Huai-Hai east region.
