| 【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 10 kg/667m2 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 1 802.30 kg/667m2，比对照增产 239 kg，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 10 kg/667m2 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 10 kg/667m2 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、
1022.30 kg/667m2, 比对照分别增产 140.73、136.23 kg，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/667m2, and the average yield was 1 802.30 kg/667m2, 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/667m2, or only the Genduowang 86 microbial
agents were applied twice by fertigation drip irrigation facilities based on the amount of 10 kg/667m2, the average yields were
1 026.80 kg/667m2 and 1 022.30 kg/667m2, 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. |
