摘要
研究了6种不同施肥处理对青海春油菜生长性状、产量、生物学产量及经济收益的影响。结果表明,氮磷配施(NP)和氮磷配施有机肥(NPM)的油菜籽产量显著高于其他施肥处理(CK、N、P、M处理)。NPM处理的油菜株高、单株角果数、千粒重、生物学产量、产值、成本在6个处理中均为最高,但纯收益为13 483.12元/hm2,仅为第3位。施肥可大幅提高油菜株高、单株角果数及千粒重,以NP和NPM处理表现最为明显。
To study the effect of different level of factorial fertilizer on rapeseed yield and profit,the field plot experiment was carried out in the soil fertilizer institute experiment station,Xining city,Qinghai province.The results indicated that the yield of NP treatment with N 120kg/ha and P2O575kg/ha and NPM treatment with N 120kg/ha,P2O5 75kg/ha and manure 3750kg/ha was higher than other applying fertilizer treatment.The NPM treatment and other applying fertilizer treatment had significant difference in the biomass yield（P0.05）.The net profit of NP and NPM were 6280.85yuan/ha and 4933.19yuan/ha,respectively.Applying fertilizer increased plant height,siliquae per plant and weight of 1000-seed-weight,and the NP and NPM treatments had advantage over other application fertilizer treatments on yield mentioned above.
