The utility model discloses a kind of based on ultrasonic wave cooperates coarse coconut bran matrix's soilless cultivation breeding acceleration device, comprising: matrix processing unit, ultrasonic atomization system and intelligent control unit.In matrix processing unit, coarse coconut bran is formed after layer structure by steam puffing, pyroligneous acid modification, probiotic solidification, bottom layer is coconut shell charcoal particle, middle layer is modified coarse coconut bran matrix, surface layer is carbonized rice hull.Ultrasonic atomization system is composed of three-dimensional spiral flow guide pipe around matrix, high-frequency piezoelectric ceramic atomization piece group and nano bubble generating device.Intelligent control unit can dynamically adjust ultrasonic frequency and working mode, simulate day-night rhythm to adjust ultrasonic and illumination.By optimizing matrix structure and ultrasonic atomization technology, nutrient solution is evenly covered root system with micron grade fog particle, while nano bubble promotes dissolved oxygen concentration, solve the problem that traditional fog culture droplet particle size is big, root system is insufficient in oxygen supply.

The application discloses a saline-alkali soil composite improver and a preparation method thereof, relates to the technical field of soil improvement, and raw materials include 18-22 parts of ion intercalation modified expanded vermiculite, 10-14 parts of humic acid, 0.2-0.4 parts of polyacrylamide, 6-9 parts of urea, 5-7 parts of diammonium phosphate, 4-6 parts of potassium sulfate, and 10-18 parts of iron modified biochar-attapulgite composite carrier immobilized microbial inoculant. The saline-alkali soil composite improver has excellent saline-alkali soil improvement effect.
