通过田间小区试验,研究了不同施肥对蚕豆成熟期干生物量、籽粒产量、养分吸收量以及肥料利用率的影响。结果表明:在相同的施氮、磷水平下(N180.0kg/hm~2、P2O5120.0kg/hm~2),有机无机配施以及单施有机肥的肥效均高于无机肥配施以及单施无机肥。羊粪+氮磷配施(MNP),籽粒产量、全株吸氮量、籽粒吸氮量、全株氮肥吸收利用率、全株钾肥吸收利用率、氮肥农学利用效率、钾肥农学利用效率均最高,分别达到6557.6kg/hm~2、227.36kg/hm~2、162.73kg/hm~2、45.49%、173.74%、5.47(kg/kg)、20.78(kg/kg),其中籽粒产量,比对照(CK)、秸秆+氮磷配施(SNP)、氮磷钾配施(NPK)、羊粪+氮配施(MN)、羊粪(M)分别增产17.67%、6.86%、4.57%、1.75%、4.99%。羊粪+氮配施(MN),籽粒吸钾量、籽粒氮肥吸收利用率、籽粒磷肥吸收利用率、籽粒钾肥吸收利用率、磷肥农学利用效率均最高,分别达到81.33kg/hm~2、34.80%、12.38%、81.95%、12.11(kg/kg)。羊粪(M),全株干生物量、全株吸磷量、籽粒吸磷量、全株吸钾量、全株磷肥吸收利用率均最高,分别达到15043.73kg/hm~2、33.85kg/hm~2、27.00kg/hm~2、194.23kg/hm~2、20.55%。
Field experiments were conducted to study the effects of different fertilization treatments on the dry biomass, grain yield, nutrient uptake and fertilizer use efficiency of Vicia faba during maturity. The results showed that under the same nitrogen and phosphorus levels (N180.0kg / hm2 and P2O5120.0kg / hm2), organic and inorganic fertilizers and organic fertilizers were higher than inorganic fertilizers and single Application of inorganic fertilizer. The combination of sheep manure and MNP, grain yield, total nitrogen uptake by plants, N uptake by grains, nitrogen uptake and utilization of whole plant, potassium uptake and utilization of whole plant, agronomic efficiency of nitrogen fertilizer and agronomic efficiency of potassium fertilizer , Respectively, reaching 6557.6kg / hm ~ 2,227.36kg / hm ~ 2,162.73kg / hm ~ 2,45.49%, 173.74%, 5.47kg / kg and 20.78kg / kg, CK, SNP, NPK, MN, and sheep manure increased by 17.67%, 6.86%, 4.57%, 1.75 %, 4.99%. The combination of sheep manure plus nitrogen application (MN), the amount of potassium absorbed by grain, nitrogen uptake and utilization rate of grain, phosphorus uptake and utilization of grain, potassium uptake efficiency of grain, and agronomic efficiency of phosphate fertilizer were the highest, reaching 81.33kg / hm ~ 2,34.80 %, 12.38%, 81.95%, 12.11 (kg / kg). Sheep manure (M), dry weight of whole plant, phosphorus uptake by whole plant, phosphorus uptake by grain, potassium uptake by whole plant, and absorption and utilization rate of whole plant phosphate fertilizer reached 15043.73kg / hm ~ 2,33.85kg / hm ~ 2, 27.00 kg / hm ~ 2, 194.23 kg / hm ~ 2, 20.55%.
