- 摘要:
- 为指导黔西北山区麦田的科学施肥，在毕节市海子街镇红堰村通过 “3414”肥料效应试验，研究了小麦产量与施肥量的关系。结果表明：1）氮磷钾肥配施能够大幅度提高小麦产量，达到6 193 kg? hm-2，比不施肥时提高55.49%；2)增施氮肥能够显著提高小麦产量，增施磷和钾肥虽然能够提高小麦产量，但是增产效果不显著；3）小麦的最大产量施肥量为纯氮107.38 kg?hm-2、P2O5 98.70 kg?hm-2、K2O 85.11 kg?hm-2。
- Abstract:
- In order to guide scientific fertilization in wheat field in the northwest of Guizhou Mountain,the relationship of fertilization rate and wheat yield were studied,based on “3414” fertilizer experiment at Hongyan village in Haizijie town of Bijie city.The results showed that wheat yield was improved after application of N,P and K fertilizers,and it reached 6 193 kg?hm-2 and increased 55.49% compared with unfertilized treatment；wheat yield improved significantly with increasing N fertilizer rates.Though the increasing of P and K fertilizer application rate could increase wheat yield,but the increasing was not significant;the maximum fertilizer amounts of wheat yield were N 107.38 kg?hm-2,P2O598.70 kg?hm-2 and K2O 85.11 kg?hm-2.
