Nutrient solution for soilless cultivation of flowers and preparation method thereof

Abstract

The invention discloses a nutrient solution for soilless cultivation of flowers and a preparation method thereof. The nutrient solution comprises the following components by weight: 8-10 parts of potassium nitrate, 5-8 parts of potassium dihydrogen phosphate, 2-6 parts of calcium nitrate terahydrate, 3-5 parts of magnesium sulfate heptahydrate, 2-6 parts of zinc sulfate, 3-8 parts of manganese chloride, 2-3 parts of boric acid, 1-3 parts of calcium superphosphate, 0.5-1 part of beta-cyclodetrin, 3-5 parts of diatomite, 0.5-2 parts of amino acid, 0.3-0.5 part of chitosan, 1-3 parts of activated carbon, 0.1-0.5 part of B group vitamin, 0-5 parts of an acidity regulator, and 300-1000 parts of water. The nutrient solution provided by the invention is suitable for soilless cultivation of flowers, by adding diatomite, beta-cyclodetrin and activated carbon, the period of validity of the nutrient solution can be up to 1 month or more, thus avoiding frequent adding of nutrient solution into cultivation water, and after use of the nutrient solution, plant height and flower color of flowers are both optimized significantly.

Description

technical field [0001] The invention relates to a nutrient solution, in particular to a nutrient solution for soilless cultivation of flowers and a preparation method thereof, belonging to the technical field of plant nutrients. Background technique [0002] Soilless cultivation is the technology of cultivating plants completely with nutrient solution without soil, which is a major innovation in human planting methods. Soilless cultivation not only grows fast, has high yield and good quality, but also liberates human planting activities from the shackles of the soil, opening up broad prospects for the realization of industrialization and automation of agricultural and horticultural production. In soilless cultivation technology, nutrient solution is the key, and different crops require different nutrient solution formulations. [0003] For flowers grown without soil, the key lies in nutrient solution, fertilizer and water and sufficient sunlight. It is fundamental and nece...
