叶面肥对设施番茄产量、品质及经济效益的影响

Effects of foliar fertilizer on yield,quality and economic benefit of greenhouse tomato

探究不同种类叶面肥对番茄植株生长势、产量、品质、商品率以及经济效益等方面的影响,为设施番茄叶面追肥提供参考依据。以番茄品种西润2007为试材,在番茄生长发育期叶面喷施5种不同叶面肥。结果表明,叶面肥均能显著促进番茄植株的生长发育,美盖美可以显著提高番茄产量,磷酸二氢钾不仅能提高番茄结果盛期和结果后期的商品率,同时也可以改善果实品质。综合分析产投比发现,喷施美盖美后的番茄经济效益最高。建议生产中选择叶面肥时,可以将美盖美和磷酸二氢钾混合喷施。其中,美盖美每次667 m^(2)用量20.00 g,磷酸二氢钾每次667 m^(2)用量20.00 mL,喷施次数开花期1次,坐果期喷施2次,每穗果采收后喷施2次。

This study was carried out to explore the effects of different types of foliar fertilizers on tomato plant growth vigor,yield,quality,commodity rate and economic benefits,and to provide a reference basis for tomato foliar top dressing.In this experiment,the tomato cultivar Xirun 2007 was used as the test material,and five different foliar fertilizers were sprayed during the growth and development period of the tomato.The results showed that all foliar fertilizers could significantly promote the growth and development of tomato plants.One kind of foliar fertilizer,Meigaimei,could significantly increase tomato yield,and Potassium dihydrogen phosphate could not only increase the commodity rate of tomatoe at the fruiting period and the later period,but also improve fruit quality.In addition,after comprehensive analysis of the ratio of production to investment,we found that the economic benefits of tomatoes were the highest after spraying with Meigaimei.Therefore,we suggest that when choosing to spray foliar fertilizers in production,it is a good choice to mix spraying of Meigaimei and Potassium dihydrogen phosphate.Along which,the spraying times include 20.00 g per 667 m^(2) of Meigaimei and 20.00 mL per 667 m^(2) of Potassium dihydrogen phosphate,the number of spraying is 1 time at the flowering stage,2 times at the fruit setting stage,and 2 times after each ear of fruit is harvested.
