Abstract:

Abstract: A field experiment studied and analyzed the effects of different fertilizer treatments on tomatoyield and nitrate nitrogen contents in vegetable lands.The results showed that regions yield of leaf fertilizer and orgnic-inorgnic compound fertilizerdone with the treatments of traditional increased by 5.3%,the amounts of residual nitrate in soil and leaching losses decreased by15.3% and 35% respectively.leaf fertilizer and orgnic-inorgnic compound fertilizer compared with other fertilizer treatments,while ensuring the production,improving the fertilizer using efficiency and reducing the nitrate nitrogen pollution.
