Embodiment 1

[0052] Example 1 Preparation of discharge activated water

[0053] 1. Discharge activation water preparation: utilization Figure 1-3 The plasma activated water preparation apparatus shown is prepared by discharging activation water, an AC voltage 10 kV, frequency 9 kHz, and an electrode I14, and the electrode I1 is connected to the ground, and the air flow rate is 1 SLM, which is inflowed by the air hole IV16, an additional air hole III12. It can be used to add helium, argon, nitrogen, and other auxiliary gases. 100 ml of deionized aqueous solution is added to the medium tube I5, and the discharge voltage is 5 min, and the 1 time deionized water discharge activation treatment is performed to obtain 100 mL discharge activated aqueous solution. Adopt Figure 1 The devices shown are prepared by discharging activated water (AC: peak - peak 5, 6, 7, 8, 9, 10 kV, frequency 1, 2, 3, 4, 5, 6, 7, 8, 9, 10kHz; pulse: peak 3, 4, 5, 6, 7, 8, 9, 10kV, frequency 1, 3, 4, 5, 6, 7, 8, 9, 10 kHz), ...

Abstract

The invention relates to the application of discharge-activated water to prepare improved nutrient solution, and belongs to the technical field of biological environment. Applied in the soilless cultivation of herbaceous plants and seed plants, the method of use is as follows: soak the seeds to accelerate germination; soak the buds in 50mL of improved nutrient solution, change the nutrient solution every day, and cultivate it at a constant temperature of 35°C after 5 days for 5‑ After 25 days, the seedlings can be cultivated; the improved nutrient solution is prepared from the following raw materials in parts by mass: 135-140 parts of potassium dihydrogen phosphate, 490-500 parts of magnesium sulfate, 2.5 parts of iron salt solution, and trace element solution 4-5 parts, 1000 parts of plasma activated water; the present invention uses the ratio of plasma activated water to improve the Hoagland nutrient solution, and its activated water state and composition can change the plasma gas composition and gas discharge conditions according to the required elements, thereby Quantitative and qualitative adjustments can be applied to the growth needs of different types of various plants.

Description

Technical field [0001] The present invention relates to the field of biotechnology environment, in particular to apply a water activated discharge the nutrient solution modified formulation. Background technique [0002] Soilless cultivation in recent decades developed a new technology to crop cultivation. Crop not grown in soil, but is grown in an aqueous solution of mineral (nutrient solution), the cultivation of crops with a nutrient solution. Cultivation and management, crop can grow normally in a sterile environment, and high yields. Soilless cultivation commonly Hoagland nutrient solution modified Hoagland nutrient solution or nutrient solution, wherein the modified Hoagland nutrient solution culture better, improving the prior art Hoagland nutrient solution as formula: nitrate tetrahydrate calcium 945mg / L, potassium nitrate 506mg / L, ammonium nitrate 80mg / L, potassium dihydrogen phosphate, 136mg / L, magnesium sulfate 493mg / L, iron salt solution 2.5mg / L, trace ele...
