不同类型基肥在西瓜上的应用效果初报

Study on the comparative experiment of different kinds of basal fertilizer applied to watermelon

为筛选出适宜大棚小西瓜种植的基肥种类,分别选择有机鱼肥、商品有机肥、生物有机肥、农家肥+生物菌剂、农家肥5种基肥类型,结果表明:采用每667 m2施用生物有机肥400 kg作基肥,种植的西瓜单果质量(2.13 kg)、坐果率(98.1%)、每667 m2产量(3 854 kg)均居第一位,中心可溶性固形物含量(11.84%)居第三位,施用效果最好,且适宜普通农户和园区种植;采用每667 m2施用有机鱼肥200 kg作基肥,其中心可溶性固形物含量最高(13.18%),同时可显著提高土壤中有机质、全氮、有效磷和速效钾含量,特别适宜合作社和园区用于土壤改良和高品质西瓜生产。

To screen the optimal basal fertilizer on the small fruit watermelon, the author carried out the comparative experiment with organic fish fertilizer, commercial organic fertilizer, bio-organic fertilizer, farmyard manure, farmyard manure and biological agents. The comprehensive properties of the small fruit watermelon by using bio-organic fertilizer （400 kg/667 m2） are best, which has highest fruit weight （2.13 kg）, fruiting rate（98.1%） and yield （3 854 kg/667 m2）. It is the suitable fertilizer for farmers and parks. Soluble solid content（11.84%） is the third. The treatment with organic fish fertilizer（200 kg/667 m2） gets the highest sugar content（13.18%）. It can significantly increase the contents of soil organic matter, total nitrogen, available phosphorus and available potassium. It is very suitable to improve soil and produce high quality watermelon by agricultural cooperatives and parks.
