Abstract

The invention relates to the field of tomato nutrient solutions, and particularly discloses an adult tomato hydroponic nutrient solution and a preparation method thereof.The adult tomato hydroponic nutrient solution is prepared from, by weight, 1900-2100 parts of a solution A and 1950-2150 parts of a solution B; the liquid A is prepared from the following raw materials in parts by weight: 245 to 270 parts of Ca (NO3) 2.4 H2O, 4.5 to 6.5 parts of Fe-EDTA (Ethylene Diamine Tetraacetic Acid), 35 to 50 parts of CaCl2 and 1690 to 1700 parts of water; the liquid B is prepared from the following raw materials in parts by weight: 60 to 70 parts of KNO3, 40 to 55 parts of KH2PO4, 170 to 180 parts of MgSO4. 7H2O, 60 to 70 parts of K2SO4, 0.2 to 0.35 part of ZnSO4. 7H2O, 0.4 to 0.6 part of MnSO4, 0.05 to 0.15 part of CuSO4. 5H2O, 0.45 to 0.65 part of H3BO3, 0.03 to 0.05 part of (NH4) 2Mo2O7 and 1630 to 1660 parts of water; the adult tomato hydroponic nutrient solution prepared by the invention has the effects of increasing the tomato yield and improving the tomato quality.

Description

technical field [0001] The application relates to the field of tomato nutrient solution, more specifically, it relates to an adult tomato hydroponic nutrient solution and a preparation method thereof. Background technique [0002] Horticultural crop hydroponic technology is a modern agricultural technology based on facility environment and scientific management. It has the advantages of easy and precise adjustment of nutrients, increase of production and quality, and is currently developing rapidly in our country. The main feature of hydroponic technology is to grow most of the roots of plants directly in the liquid layer of the nutrient solution, and provide the nutrients and water needed for crop growth through the hydroponic nutrient solution. Therefore, the preparation of the hydroponic nutrient solution is a hydroponic technology. It affects the growth, development, quality and yield of crops. [0003] At present, the use of hydroponics technology in tomato greenhouse ...
