Abstract:

It explored the ratio of organic fertilizer replacing nitrogen fertilizer in the piedmont plain of Hebei Province,in order to provide a basis for reducing the amount and increasing the efficiency of nitrogen in wheat in this area.Field experiments were carried out in Boyuan farm in Yongnian,Hebei Province for two consecutive years,and five organic and inorganic fertilizer combination treatments were set up.The results showed that organic fertilizer instead of 20% and 40% chemical fertilizer could significantly improve the number of grains per spike and yield.Compared with the high nitrogen and saving nitrogen treatment of single chemical fertilizer application,the yield increased by more than 4.0%,and the number of grains per spike increased by 3.6—5.6.Most of the grain quality indexes for organic fertilizer instead of 20% and 40% chemical fertilizer treatment,and saving nitrogen treatment were better,and the stabilization time increased by 2.2—2.7 min,the tensile area increased by 10.5—17.5 cm2,and the maximum tensile resistance increased by 28.0—75.5 EU.Various nitrogen efficiency indicators of treatment for organic fertilizer instead of 20% were higher.The nitrogen fertilizer efficiency,nitrogen utilization efficiency,and nitrogen harvest index increased 109.3%,9.3% and 11.3% respectively compared with high nitrogen treatment,and 6.9%,8.5% and 8.3% respectively compared with the saving nitrogen treatment.When organic fertilizer replaced chemical fertilizer in different proportions,nitrate nitrogen in 0—20 cm soil appeared "surface accumulation",and the content of nitrate nitrogen increased,which was more than 38.5% higher than that of the saving nitrogen treatment.The nitrate nitrogen in 20—40 cm soil was significantly higher for the saving nitrogen treatment and the high nitrogen application treatment.Organic fertilizer instead of 20% nitrogen fertilizer treatment had the best yield and grain quality,significantly improve the nitrate nitrogen content in 0—40 cm soil,improve the nitrogen absorption and utilization of wheat,and finally obtain higher environmental benefits.
