蔬菜节水灌溉和水溶肥料试验初报

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 m^3/0.067 hm^2,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 hm^2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%。

Experiment on Water Saving Irrigation and Water Soluble Fertilizer for Vegetables

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 m^3/0.067 hm^2 of water and 53%of water.Compared with the control,the yield of water-soluble fertilizer increased by 417~667 kg per 0.067 hm^2,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%.
