蔬菜节水灌溉和水溶肥料试验初报

Experiment on Water Saving Irrigation and Water Soluble Fertilizer for Vegetables

摘要: 为进一步集成创新水肥一体化节水农业技术模式,开展新技术、新产品、新材料试验示范,在小店区选择有代表性的地块,开展蔬菜节水灌溉和水溶肥料试验示范,结果显示,蔬菜喷灌与常规灌溉相比,节水80 m3/0.067 hm2,节水率53%。水溶肥在蔬菜上增产效果明显,较对照相比,每0.067 hm2增产417～667 kg,增产率达11.4%～18.2%。其中氨基酸水溶肥(氨基酸100 g/L)增产率18.2%,高氮型水溶肥(30-10-10+TE)增产率17.0%,平衡型水溶肥(20-20-20+TE)增产率13.6%,腐植酸水溶肥(腐植酸40 g/L)增产率11.4%。

Abstract: In this paper, a representative plot was selected in Xiaodian District to carry out water-saving irrigation and water-soluble fertilizer experiment demonstration of vegetables. The results showed that compared with conventional irrigation, vegetable sprinkler irrigation saved 80 m3/0.067 hm2 of water and 53% of water. Compared with the control, the yield of water-soluble fertilizer increased by417～667 kg per 0.067 hm2, and the yield increased by 11.4%～18.2%. Among them, amino acid water-soluble fertilizer（amino acid 100 g/L） increased production by 18.2%, high nitrogen water-soluble fertilizer（30-10-10 + TE） increased production by 17.0%, balanced water-soluble fertilizer（20-20-20 + TE） increased production by 13.6%, humic acid water-soluble fertilizer（humic acid 40 g/L）increased production by 11.4%.
