砖红壤施用微生物菌肥对南瓜的增产效果试验

Effect of Microbial Fertilizer on the Yield Increase of Pumpkin in Latosol

【目的】研究雷州半岛砖红壤施用微生物菌肥对南瓜的增产效果。【方法】以西洋小南瓜为试验作物,采用水肥一体化设施滴灌增施根多旺86菌剂、人工施保根120微生物菌肥作基肥及水肥一体化设施滴灌增施根多旺86菌剂的方法,其他基肥和追肥按西洋小南瓜生产常规管理,以明确雷州半岛砖红壤中增施根多旺86菌剂和保根120微生物菌肥对种植西洋小南瓜农艺性状、经济性状等的影响。【结果】在雷州半岛砖红壤的粘砖土上种植西洋小南瓜,按10kg/667m^2的量通过水肥一体化设备滴灌增施根多旺86菌剂2次,平均单产达1802.30kg/667m^2,比对照增产239kg,增产率15.29%;在雷州半岛砖红壤的砂砖土上种植西洋小南瓜,基肥增施保根120微生物菌肥,再按10kg/667m^2的量通过水肥一体化设备滴灌增施根多旺86菌剂2次,或仅10kg/667m^2的量通过水肥一体化设备滴灌增追施根多旺86菌剂2次,平均单产分别达1026.80、1022.30kg/667m^2,比对照分别增产140.73、136.23kg,增产率为15.88%和15.37%;单株瓜数和瓜重增加导致单位面积产量的增加。【结论】雷州半岛砖红壤施用微生物菌肥对西洋小南瓜的增产效果明显,值得推广应用。

【Objective】The effect of microbial fertilizer on the yield increase of pumpkin in latosol of Leizhou Peninsula was studied.【Methods】The western small pumpkins were used as test crops.With artificial application of Baogen 120 microbial fertilizer as base fertilizer,the fertigation facilities were used to increase the application of Genduowang 86 microbial agents by drip irrigation,and other base fertilizers and top dressings were routinely managed according to the production of western small pumpkins.The effects of the application of Genduowang 86 microbial agents and Baogen 120 microbial fertilizer on the agronomic traits and economic traits of western small pumpkins planted in latosol of Leizhou Peninsula were determined.【Results】When planting western small pumpkins on the sticky brick soil in Leizhou Peninsula,the Genduowang 86 microbial agents were applied twice by fertigation drip irrigation facilities according to the amount of 10 kg/667m^2,and the average yield was 1 802.30 kg/667m^2,which was 239 kg higher than that of the control,with a yield increase rate of 15.29%.When planting western small pumpkins on the sand brick soil in Leizhou Peninsula,the base fertilizer was applied with Baogen 120 microbial fertilizer and then the Genduowang 86 microbial agents were applied twice by fertigation drip irrigation facilities according to the amount of 10 kg/667m^2,or only the Genduowang 86 microbial agents were applied twice by fertigation drip irrigation facilities based on the amount of 10 kg/667m^2,the average yields were 1 026.80 kg/667m^2 and 1 022.30 kg/667m^2,with increased yields of 140.73 kg and 136.23 kg compared with those of the control,and yield increase rates of 15.88%and 15.37%,respectively.The number of pumpkins per plant and the increase in pumpkin weight lead to the yield increase per unit area.【Conclusion】The application of microbial fertilizer in latosol of Leizhou Peninsula has obvious effect on the yield increase of western small pumpkin.The technology is worth being promoted in the production of western small pumpkin in Leizhou Peninsula.
