Abstract

The invention relates to a seedling-raising fertilizer for tomato, belonging to the technical field of industrial seedling-raising fertilizers. The seedling-raising fertilizer for the tomato is characterized by comprising the following components by weight: 30 to 40% of calcium magnesium nitrate, 35 to 45% of potassium nitrate, 15 to 25% of potassium dihydrogen phosphate, 0.5 to 1% of EDTA-Fe, 0.1 to 0.3% of EDTA-Zn, 0.06 to 0.1% of EDTA-Cu, 0.2 to 0.5% of EDTA-Mn, 0.1 to 0.2% of boric acid, 0.01 to 0.02% of ammonium molybdate and 0.7 to 1.2% of EDTA2Na. In a formula of the fertilizer in the invention, chelated trace elements are used to replace sulfate trace elements, and a complexing agent is added to prevent calcium phosphate from precipitation, so the prepared seedling-raising fertilizer is capable of meeting the nutritional needs of tomato seedling raising and can be completely dissolved; meanwhile, the seedling-raising fertilizer has the advantages of simple components, easily-available raw materials, low cost, convenient operation, economy, practicality, applicability to industrial vegetable seedling raising, etc.

Description

technical field [0001] The invention belongs to the technical field of industrial seedling-raising fertilizers, in particular to a tomato seedling-raising fertilizer. Background technique [0002] Vegetable industrialized seedlings emerge neatly and save land, which is the development direction of modern agriculture. Industrial seedlings generally use soilless substrates, and the nutrients used for seedling growth and development are supplied through fertilizers, so fertilizers are required to have the characteristics of complete nutrition and high purity. [0003] At present, in order to avoid precipitation of some nutrient elements when mixed, seedling fertilizers are generally divided into two types, one containing calcium and the other without calcium. When fertilizing, the two types of fertilizers are required to be used alternately to ensure the normal growth of seedlings. Owing to will constantly alternate kind, bring certain trouble to seedling raising operation. M...
