摘要:

【目的】采用控释氮肥掺混磷钾等养分在冬小麦上一次性施用,揭示减肥、增效、节本增收方面的效应,为冬小麦轻简化生产提供技术支撑。【方法】于2011—2012、2012—2013、2013—2014年,选择在黄淮海东部不同冬小麦生态区进行控释氮肥随小麦播种一次性施用试验。与普通氮肥分次施用(农民习惯施肥(FP)和优化施肥(OPT))对比,通过设置控释氮肥a等量氮素投入(CRFa)、控释氮肥a和控释氮肥b分别减量20%氮素投入(80%CRFa与80%CRFb)处理,经过3年31个试验对产量、养分效率、节本增收等进行研究。【结果】控释氮肥在冬小麦上一次性施用总体表现稳产或小幅增产趋势,相比普通氮肥分次施用(OPT)3年平均增产2.6%,增产点位数占全部试验点数量的83.9%。减少20%氮素投入的控释氮肥处理稳产增产点比例显著降低,两种控释氮肥中生物可降解型控释氮肥a的产量效应优于有机树脂包膜控释氮肥b;4种施肥模式随土壤质地由轻到重平均施氮增产分别为10.7%、17.4%增长到19.7%,控释氮肥应用在砂质或壤质土壤的相对增产效应(较OPT)优于黏质土壤;在中低产量水平下控释氮肥一次性施用相对产量效应(较OPT)优于高产水平地块。CRFa、80%CRFa和80%CRFb处理相比农民习惯施肥(FP)分别节约氮素投入14.7、59.3、59.3 kg N·hm-2,CRFa、80%CRFa和80%CRFb处理相比OPT氮肥偏生产力(PFPN)分别提高0.4、7.32、6.93 kg·kg-1,氮肥表观利用率分别提高1.5、8.6、6.2个百分点。CRFa和80%CRFa处理相比OPT节本增收分别达到543.8、150.3元/hm2。【结论】冬小麦上控释氮肥配合其他养分底肥一次性施用、后期不再追肥的方式相比习惯施肥及普通肥料优化施用在产量稳定性、提高氮效率、节约劳动力及节本增收等方面优势明显。本试验条件下CRFa和80%CRFa处理效果较好。推荐减少20%氮用量CRFa施肥模式在黄淮东部冬小麦生产应用。

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 (PFPN) 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.
