Aquaculture nutrient solution of leaf vegetables and use method for aquaculture nutrient solution

Abstract

The invention discloses an aquaculture nutrient solution of leaf vegetables and a use method for the aquaculture nutrient solution and belongs to the technical field of aquaculture nutrient solutions.The nutrient solution per 1,000kg disclosed by the invention is prepared from the ingredients: 800g to 900g of calcium nitrate, 400g to 500g of potassium nitrate, 30g to 50g of ammonium nitrate, 300gto 400g of magnesium sulfate, 300g to 400g of potassium sulfate, 400g to 500g of potassium dihydrogen phosphate, 20g to 40g of iron chelate, 3g to 3.5g of boric acid, 0.22g to 0.24g of zinc sulfate,1.5g to 2g of manganese sulfate, 0.06g to 0.08g of copper sulfate and 0.02g to 0.03g of ammonium molybdate. The nutrient solution disclosed by the invention is simple to prepare and convenient in useand can be used for supplying balanced nutrients to all kinds of leaf vegetables; and after the nutrient solution disclosed by the invention is applied to aquaculture, the nutrient solution can be rapidly absorbed by the vegetables, the growth of the leaf vegetables is promoted, and the yield and quality of the leaf vegetables are improved.

Description

technical field [0001] The invention belongs to the technical field of hydroponic nutrient solution, and in particular relates to a hydroponic nutrient solution for leafy vegetables and a using method thereof. Background technique [0002] Leafy vegetables are vegetables in which the fat and tender leaves and petioles of plants are used as edible parts. According to the cultivation characteristics, it can be divided into three types: ordinary leafy vegetables, headed leafy vegetables and spicy leafy vegetables. Celery, leeks, onions, etc. [0003] Currently, there are many varieties of leafy vegetables, and many special-purpose nutrient solutions appear on the market. However, if all kinds of vegetables are cultivated with special-purpose nutrient solutions, the cultivation operation will be complicated and the production cost will be high. When a variety of leafy vegetables are cultivated in one area of ​​the planting base, if a nutrient solution pool is shared, the dedic...

Problems solved by technology

However, it is often caused by excessive accumulation of calcium, magnesium, etc., especially sodium, resulting in poor plant growth.

That is, the change of EC value cannot reflect the change of the concentration of a single element in the nutrient solution and the proportion of each component, resulting in excess or lack of nutrition.
