通过在设施大棚番茄开展常规单质化肥与水溶肥追施的对比试验,探讨不同追肥对番茄产量及经济效益的影响。结果表明,2个水溶肥追施的处理番茄产量均高于追施单质化肥的对照处理的产量,其中处理2追施四川国光水溶肥的处理产量最高,经济效益最好,产量比追施单质化肥的对照处理亩增产1 079.63 kg,纯收益比对照处理亩增收2 641.06元。追施水溶肥与追施单质化肥相比,确实能起到增产增收的效果,这将为永安市实施智能化水肥一体化技术条件下水肥耦合机制中选取适合的水溶肥提供技术参考。
The effects of different top dressing on the yield and economic efficiency of tomato were studied by comparing the conventional top-dressing fertilizer and top-dressing with water-soluble fertilizer in the greenhouse of the facility. The results showed that the yield of two tomato topdressing treatments was higher than that of the top dressing chemical fertilizers. The treatment yield of topdressing Sichuan Guoguang water soluble fertilizer was the highest, the economic benefit was the best, Fertilizer control treatment acres increase 1 079.63 kg, net income than the control treatment Mu increase 2 641.06 yuan. Compared with topdressing chemical fertilizers, topdressing water-soluble fertilizer can really play an effect of increasing yield and income, which will provide technical reference for selecting appropriate water-soluble fertilizer in the mechanism of water-fertilizer coupling under the condition of intelligent water-fertilizer integration in Yong’an.
