再生薏苡产量与效益试验初报

Preliminary Study on Yield and Economic Benefits of Regeneration Coix lacryma-jobi L

为探索薏苡节本增效种植模式,采用同田大区对比试验方法,分析再生薏苡与当年播种薏苡的产量差异及成本投入。结果表明,再生薏苡生育时期比当年播种薏苡提早,提前35d成熟;有效苗显著增多,株高降低,结实率提高,千粒重增大,单产297.26kg/667m2,增产22.15%;但成苗率、苗总粒数、苗实粒数比当年播种薏苡略低。再生薏苡在土地翻耕、施基肥、播种环节节省人工36.21%,节约种子、基肥投入,节本增效显著,具有较好的推广应用价值。

In order to explore the cost-effective synergistic planting model,a big region comparison test on a same field was conducted to analyzed the yield and economic benefits between regeneration Coix lacryma-jobi L. and sowing Coix lacryma-jobi L. The results showed that the growth period of regeneration Coix lacryma-jobi L. was 35 days earlier and plant height was lower than sowing Coix lacryma-jobi L.,it＇s yield was 297. 26 kg/667 m2 which increased by 22. 15% due to the more effective seedlings,higher setting rate,more 1000-grains weight,but the percentage of seedlings,grains number were less. The regeneration Coix lacryma-jobi L.cultivation model have significantly increase efficiency that can save 36. 21% labor force during the program of land plowing,fertilization and sowing,and also save the seed and basal fertilizer amount. It is indicated that regeneration Coix lacryma-jobi L. have good promotion and application value.
