Embodiment 1

[0068] Present embodiment lettuce hydroponic nutrient solution formula is as shown in the following table:

[0069] Table 1 Leafy vegetable hydroponic nutrient solution formula

[0070]

[0071] Remarks: Because the biological agent contains active bacteria, it needs to be prepared immediately after use, and it is directly added to the diluted nutrient solution according to the standard concentration for use.

[0072] The preparation method is as follows: if the original liquid barrel is 1000L, prepare two 1000L barrels in advance, and mark A and B for distinction. Add 46.8Kg of fully dissolved calcium nitrate to stock solution bucket A, then add 141.4Kg of fully dissolved potassium nitrate, then add 4.8Kg of fully dissolved Fe-EDTA (chelated iron), and set the volume to 1000L. Add 9.5Kg of fully dissolved ammonium dihydrogen phosphate to stock solution barrel B, then add 196.8Kg of fully dissolved magnesium sulfate, then add 600g of fully dissolved boric acid, 400g of man...

Abstract

The invention relates to the technical field of plant culture, in particular to a leafy vegetable water culture nutrient solution and a preparation method and application thereof. The water culture nutrient solution is prepared from 220 to 250mg / L of calcium nitrate, 680 to 720mg / L of potassium nitrate, 180 to 200mg / L of ammonium dihydrogen phosphate, 240 to 260mg / L of magnesium sulfate, 2.0 to 3.0mg / L of boric acid, 1.8 to 2.2mg / L of manganese sulfate, 0.20 to 0.24mg / L of zinc sulfate, 0.03 to 0.07mg / L of copper sulfate, and 0.01 to 0.03mg / L of sodium molybdate. A formula of the water culture nutrient solution is mainly suitable for planting leafy vegetables under a water culture condition, the mouthfeel of leafy vegetables can be improved effectively, and the yield and quality of the leafy vegetables can be increased and improved.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a leaf vegetable hydroponic nutrient solution and a preparation method and application thereof. Background technique [0002] Vegetables are one of the essential foods in people's daily diet and are a kind of green food. Vegetables can provide nutrients such as various vitamins and minerals necessary for the human body. According to the statistics of the International Food and Agriculture Organization in 1990, 90% of VC and 60% of VA needed by the human body come from vegetables. In addition, there are a variety of phytochemicals in vegetables, which are recognized as effective components for health. Currently, nutrients in fruits and vegetables can effectively prevent chronic and degenerative diseases, and are being discovered by people. [0003] According to different edible organs, vegetables are divided into root vegetables, stem vegetables, leaf vegetables, cauli...
