不同水溶肥在早春大棚甜瓜生产上的肥效试验

摘要：为探寻最适于甜瓜种植的水溶肥,以5种类型水溶肥,即复合微生物水溶肥、大量元素水溶肥料、中微量元素水溶肥、含腐植酸水溶性肥料、含氨基酸水溶性肥料为供试肥料,以甜瓜博洋9号为供试作物,对比分析了不同水溶肥对甜瓜产量和品质及土壤理化性质的影响。结果表明：施用复合微生物水溶肥后甜瓜产量最高,为115.23 t/hm2,果实含糖量、叶绿素含量（SPAD值）和土壤有机质含量、碱解氮含量也较高,分别为14.47%、59.99和10.03 g/kg、128.21 mg/kg。所以,复合微生物水溶肥更有利于甜瓜的生长和土壤改良。

Effects of Different Water-soluble Fertilizers on Melon Production in Greenhouse in Early Spring

Abstract: In order to find out the most suitable water-soluble fertilizer for melon planting, five types of water-soluble fertilizers, namely compound microbial water-soluble fertilizer, large-element water-soluble fertilizer, medium and trace element water-soluble fertilizer, humic acid water-soluble fertilizer and amino acid water-soluble fertilizer, were used as test fertilizers, and melon cultivar ''Boyang No.9'' was used as test crop. The effects of different water-soluble fertilizers on yield and quality of melon, and physical and chemical properties of soil were compared and analyzed, the results showed that the yield of melon applying compound microbial water-soluble fertilizer was the highest, which was 115.23 t/hm2, and the sugar content, chlorophyll content (SPAD value), organic matter content and alkali-hydrolyzable nitrogen content of soil were also higher, which were 14.47%, 59.99 and 10.03 g/kg, 128.21 mg/kg, respectively. Therefore, compound microbial water-soluble fertilizer was more beneficial to growth of melon and soil improvement.
