不同节水施肥处理对国审富麦2008产量及品质的影响

Study on the Effects of Water-saving and Fertilizer on Yield and Quality of Fumai 2008

以国审富麦2008为试材,研究了不同灌水和施肥处理对该小麦品种产量和主要品质性状的影响。结果表明,灌水5次的产量显著高于灌水2次,但与灌水3次差异不显著,湿面筋、沉降值含量以灌水2次最高,比较灌水5次(CK),灌水2次增收681.45元/hm2;底施和追施比例3∶7为宜,全生育期施氮量300和225 kg/hm2的籽粒产量显著高于150 kg/hm2处理;全生育期施磷量135、160 kg/hm2的籽粒产量差异不显著,显著高于100 kg/hm2处理;随钾肥用量增加,该品种产量呈先上升后下降趋势;增施磷、钾肥有改良品质性状趋势,但效果不显著。在该试验条件下,综合考虑产量、品质和经济效益,以灌水2次,施氮量225 kg/hm2,底施和追施比例为3∶7,磷肥135kg/hm2,钾肥75 kg/hm2的处理为宜。

With Fumai 2008 as test materials,the effects of different treatments of water-saving and fertilizer on yield and main quality characters of Fumai 2008 were studied.The results showed that the yield of the treatment of irrigation 5 times was significantly higher than that of irrigation 2 times,and had no obvious difference with treatment of irrigation 3 times,there had the highest contents of Wet gluten and Sedimentation value with irrigation 2 times,the purely income of treatment of irrigation 2 times increased 681.45 yuan/hm^2 than that of CK;the grain yield was the highest in the treatment of proportion of base fertilizer to top dressing was 7∶3,the yield of treatments of applied Nitrogen 300,225 kg/hm^2 was significantly higher than that of 150 kg/hm^2;there had no obvious difference of yield in the treatments of 135,160 kg/hm^2,but significantly higher than that of 100 kg/hm^2;the yield showed increasing trend by increased use of Potassium application;It can improved the quality characters of Fumai 2008 by increasing Phosphorus and Potassium,but had no obvious effect.In the test condition,irrigation 2 times,Nitrogen application 3∶7,225 kg/hm^2 Nitrogen,135 kg/hm^2 Phosphorus and 75 kg/hm^2 Potassium application was the best for grain yield.
