Problems solved by technology

The most important thing in the process of soilless cultivation is the choice of nutrient solution. Although the nutrient solution sold on the market is relatively comprehensive in nutrition, the growth cycle of the melons and fruits generally cultivated is long, and the nutrients are relatively easy to lose.

Abstract

The invention provides a soilless culture nutrient solution for tomatoes; the soilless culture nutrient solution consists of the following components: potassium nitrate, calcium superphosphate, ammonium nitrate, magnesium sulfate, ferrous sulfate, copper sulfate, boric acid, manganese sulfate, molybdenum sulfate, zinc sulfate, pimacol, nitrogen-fixing bacteria, potassium bacteria, photosynthetic bacteria and water. The invention also discloses a preparation method of the nutrient solution. The soilless culture nutrient solution for tomatoes disclosed by the invention is simple in formula and comprehensive in nutrition, and the nutrient solution can be used for guaranteeing the nutritional requirements of the tomatoes in entire seedling culture and growth processes and enhancing the stress resistance of the tomatoes.

Description

Technical field: [0001] The invention relates to the field of plant soilless cultivation, in particular to a tomato soilless cultivation nutrient solution. Background technique: [0002] Soilless cultivation refers to a cultivation method that does not use natural soil, but uses a substrate or only uses a substrate when raising seedlings, and uses a nutrient solution to irrigate crops without using a substrate after planting. The main advantage of soilless cultivation is that it can avoid soil-borne diseases and insect pests and continuous cropping obstacles, which is one of the main problems in greenhouse production. [0003] At present, it is difficult to find a piece of land without pollution in the suburbs of big cities. The soilless cultivation substrate is artificially prepared, with good physical properties, water saving, fertilizer saving, and can increase crop yield. It can be used in all areas that are not suitable for general agricultural cultivation crop product...
