摘要
为了探寻小扁豆合理安全施肥方案,在旱地基施不同量有机肥(O1:750 kg/hm^(2);O2:1500 kg/hm^(2);O3:2250 kg/hm^(2);O4:3000 kg/hm^(2);O5:3750 kg/hm^(2))、化肥和有机肥混合(C+O:161.7 kg/hm^(2)+1500 kg/hm^(2))、单施化肥(C:161.7 kg/hm^(2)),以不施肥(CK)为对照。通过测定出苗率、生长发育指标并在采收期测定产量指标,最后对各处理进行综合因子评判。发现在纯有机肥O3栽培条件下小扁豆出苗率最高为87.85%,农艺性状明显优化,产量最高1356.30 kg/hm^(2),较CK和C分别显著增产32.68%和33.04%。处理CK株幅、一级分枝数均最大,但结荚率较低,经济产量低。处理C小扁豆茎粗、一级分枝数、生物量和产量均较低。纯施有机肥对小扁豆具有显著增效作用,有机肥施用量以2250 kg/hm^(2)为宜,建议在小扁豆标准化栽培中推荐应用,以改变经济作物依赖化肥的生产现状,促进粮食绿色有机栽培。
In order to explore a reasonable and safe fertilization scheme for Lens culinaris,different amounts of basal organic fertilizer(O1:750 kg/hm^(2);O2:1500 kg/hm^(2);O3:2250 kg/hm^(2);O4:3000 kg/hm^(2);O5:3750 kg/hm^(2)),chemical fertilizer and organic fertilizer mixture(C+O:161.7 kg/hm^(2)+1500 kg/hm^(2)),chemical fertilizer alone(C:161.7 kg/hm^(2)),and no fertilization(CK)as control.By measuring the emergence rate,growth and development indicators,the yield indicators were measured during the harvest period.Finally,the comprehensive factor evaluation of each treatment was carried out.The results showed that seedling emergence rate of Lens culinaris under pure organic fertilizer O3 was the highest(87.85%),agronomic traits were significantly optimized,and the yield was the highest(1356.30 kg/hm^(2)),which was 32.68%and 33.04%higher than CK and C.The plant size and the number of primary branches in CK treatment were the largest,but the pod setting rate and economic yield were lower.The stem diameter,number of primary branches,biomass and yield of Lens culinaris in treatment C were lower.Pure organic fertilizer had a significant synergistic effect on Lens culinaris,and the appropriate application rate of organic fertilizer was 2250 kg/hm^(2).It was recommended that the organic fertilizer should be applied in the standardized cultivation of Lens culinaris,so as to change the production status of economic crops that rely on chemical fertilizers and promote the green organic cultivation of grain.
