Problems solved by technology

Therefore, the cultivation of leafy vegetables is large, takes up a lot of farmland, and consumes more manpower and material resources. It is an inevitable trend to develop soilless cultivation techniques for leafy vegetables.
However, the current soilless cultivation technology can only prepare its special nutrient solution for each leafy vegetable, and the yield is low. Facing a wide variety of leafy vegetables, large-scale and systematic soilless cultivation has been challenged. limit

Embodiment

[0010] When cultivating regional multi-variety leafy vegetables, specific implementation can be carried out according to the following steps:

[0011] Add 700 grams of potassium nitrate and 800 grams of calcium nitrate to one ton of unpolluted water, and stir evenly for 15 minutes; then add 150 grams of ammonium dihydrogen phosphate, 500 grams of magnesium sulfate, 2.0 grams of manganese sulfate, 0.5 grams of zinc sulfate, Add copper sulfate, 0.03 grams of ammonium molybdate and 3 grams of borax, stir while adding, and continue stirring for 10 minutes after adding, measure the EC value and pH value of the solution; mix EDTA solution and ferrous sulfate solution in a certain proportion to form a chelated iron solution , Store away from light for 48 hours; slowly add the chelated iron solution into the solution, adjust and control the EC value of the solution to be between 1.5 and 2.5 mS / cm, and the pH value to be around 6.5.

[0012] The prepared nutrient solution is sent to a ...

Abstract

The invention provides a universal nutrient solution for soilless culture leafy vegetables and belongs to the technical field of soilless culture. A formula is as follows: 1 ton of water contains 600-700g of potassium nitrate, 400-500g of magnesium sulfate, 150-200g of ammonium dihydrogen phosphate, 800-900g of calcium nitrate, 20-60g of chelated iron, 2-3g of borax, 1.5-2.0g of manganese sulfate, 0.3-0.5g of zinc sulfate, 0.1-0.2g of copper sulfate and 0.01-0.05g of ammonium molybdate. Aiming at the special leafy vegetable nutrient solution for the current soilless culture, the nutrient solution provided by the invention has the characteristics of wide application, good culture effect and high yield, and the problem of mixed soilless culture of multiple varieties of leafy vegetables is solved. The nutrient solution provided by the invention is suitable for soilless culture of multiple varieties of leafy vegetables; and by using the nutrient solution, the yield is improved by more than 10%, and the effective management of a regional multiple-variety leafy vegetable mixing culture system in an agricultural sightseeing garden is achieved.

Description

technical field [0001] The invention belongs to the technical field of soilless cultivation of plants, and in particular relates to a general nutrient solution for soilless cultivation of leafy vegetables. Background technique [0002] Leafy vegetables have many varieties and rich nutrition. They are green food in the true sense and are deeply loved by consumers. Therefore, the amount of cultivation of leafy vegetables is large, occupying a lot of farmland, and consuming more manpower and material resources. It is an inevitable trend to develop soilless cultivation techniques for leafy vegetables. However, the current soilless cultivation technology can only prepare its special nutrient solution for each leafy vegetable, and the yield is low. Facing a wide variety of leafy vegetables, large-scale and systematic soilless cultivation has been challenged. limit. Contents of the invention [0003] The invention overcomes the disadvantages of the special-purpose nutrient solu...
