Hydroponic nutrient solution for wheat seedlings and preparation method thereof

Abstract

The invention discloses a hydroponic nutrient solution for wheat seedlings and a preparation method thereof, and relates to the technical field of soilless culture. The hydroponic nutrient solution for the wheat seedlings per ton is prepared from 470-480 g of calcium nitrate terahydrate, 30-40 g of mono-potassium phosphate, 130-140 g of potassium sulfate, 160-170 g of magnesium sulfate heptahydrate, 5-10 g of ferric chloride hexahydrate, 0.1-0.5 g of manganese chloride tetrahydrate, 1-2 g of boric acid, 0.1-0.5 g of copper sulfate pentahydrate, 0.5-1.0 g of zinc sulfate heptahydrate, 0.1-0.5 g of ammonium molybdate and water as a solvent. The hydroponic nutrient solution for the wheat seedlings is balanced in nutrition, the proportion of each element of the nutrient solution is kept balanced within a certain range during a relatively long time, macro-elements and micro-elements are adopted in a balanced mode, at the same time, the application amount of the nutrients is reduced, and the problems are solved that for a long time, nutrient solutions for the wheat seedlings for experimental use are not targeted, and over-nutrition occurs frequently.

Description

technical field [0001] The invention relates to the technical field of soilless cultivation, in particular to a wheat seedling hydroponic nutrient solution and a preparation method thereof. Background technique [0002] Wheat is one of the main food crops in my country, and it is a crop variety related to food security. The whole life of wheat goes through seed germination, seedling emergence, tillering, jointing, booting, heading, flowering, filling, and maturity. During the whole growth process of wheat, a series of morphological and physiological changes will occur, and various organs will appear and form in sequence, finally forming crop yield. At present, the research directions of wheat mainly include: physiological ecology, biotechnology and variety improvement, cultivation technology (stress resistance, high yield, high efficiency), quality improvement, etc. These directions involve various stages of wheat growth, but indoor experiments mostly focus on the seedling...
