Abstract

The invention provides a tomato fertilizer. The tomato fertilizer comprises, by weight, 47-49 parts of a nitrogen fertilizer, 70-80 parts of a phosphorus fertilizer, 30-40 parts of a potassium fertilizer and 450-500 parts of medium and trace elements. The invention also discloses a using method of the fertilizer. Results of two years of experiments show that the tomato yield can be increased by upto 50%, the nitrate content of tomato fruits can be reduced by up to 17%, the soluble sugar content of the tomato can be increased by 16%, the vitamin C content can be increased by 31%, the quality of tomato is improved, and the safety of foods is ensured.

Description

technical field [0001] The invention relates to the field of agricultural production, in particular to a tomato fertilizer and its use and application. Background technique [0002] As the main vegetable, tomato has high nutritional value and is consumed in a huge amount. Eating tomato can meet the human body's demand for some vitamins and minerals. At the same time, tomato is a high-yielding crop that requires a lot of water and fertilizer. Therefore, in the tomato planting process, growers not only need to consider improving the yield and quality of tomato, but also implement the policy of saving water and fertilizer in crop production. Therefore, in the planting process, not only the water and fertilizer needs of tomatoes must be met, but also a suitable water and fertilizer supply method, as well as a suitable water and fertilizer formula are required. [0003] Many researchers put the task of improving crop yield and quality first on the selection of fertilizers, and ...
