Further, the concrete operations of the aeration are that air is passed through into biogas slurry, and duration of ventilation is 0.5-6 hours.
Further, described plus water amount is 1-10 times of biogas slurry amount.
Application of the biogas slurry of the present invention as the nutrient solution of soilless hydroponic culture plant.
Compared with prior art, the invention has the following advantages:
Design science of the present invention, it is easy to operate, using soilless hydroponic culture plant nutrition liquid made from the method for the present invention, both sufficiently
Biogas slurry is utilized, and is able to satisfy the growth demand of different plants.
The present invention uses after being aerated biogas slurry, keeps the reproducibility ingredient in biogas slurry fully oxidized, efficiently avoids biogas slurry
Oxygen is fought for plant when use, influences plant root system development, leads to crop leaf jaundice, wilting problem.
After fresh biogas slurry discharge, a large amount of harmful virus and bacterium can be bred in an atmosphere, if will contain virus and bacterium
Biogas slurry directly irrigated, it will bring security risk to crops.The present invention uses after biogas slurry sterilizes, and eliminates nocuousness
Threat of the bacterium to plant, has fully ensured that the healthy growth of plant.
The present invention can be provided comprehensive, sufficient using biogas slurry as soilless hydroponic culture plant nutrition liquid for soilless hydroponic culture plant
Nutrition meets the growth demand in its each stage, and easy to operate, production cost is low, is suitable for promoting the use of.
The present invention does not remove the suspended matter in biogas slurry, makes it when as mill water culture nutrient solution, and energy slow release nutrient is protected
Demonstrate,prove demand of plant growth.
