施肥对黄土母质生土稻田产量及品质的影响

Effects of fertilization in paddy soil of loess maternal on yield and quality

[目的]寻求黄土母质生土复垫后的戈壁滩稻田产量、品质提升的培肥方式。[方法]于2017—2018年连续2年,选用龙稻15号水稻品种,设置不施肥料、单施化肥、单施有机肥和有机无机配施4种处理方式,在黄土复垫后的生土稻田区进行定点试验,研究不同肥料配施对水稻产量、品质指标的影响。[结果]生土施肥后,产量逐年不断提高,增产效果为有机无机配施>单化肥>但有机肥;品质分析表明,有机肥参与的培肥方式显著降低了大米的垩白度、提高了稻米的整精米率,降低了直链淀粉含量,而单施无机肥则降低了稻米的品质参数。[结论]有机无机配合施用是快速改良黄土母质生土获得高产优质的优化培肥方式。

[Objective]The effects of four fertilization treatments in paddy soil of loess maternal on yield and quality were studied in 2017-2018.[Results]The result showed that the yield of paddy after fertilizer increased year by year, The range of increased yield were organic and inorganic fertilizer>Single chemical fertilizer>single organic fertilizer;The quality of rice was significantly reduced by treatments with organic;in the two- year experiment, Single chemical fertilizer increased yield but reduced quality.[Conclusion]so, the combination of organic and inorganic fertilizer were best mode in fertilization in paddy soil of Loess Maternal.
