[0023] The fruit tree growth-promoting fertilizer provided by the invention comprises bamboo willow bark water extract. In parts by weight, the water extract of bamboo willow bark is preferably 12-14 parts, more preferably 13 parts. The preparation method of described bamboo willow bark water extract preferably comprises the following steps:
[0024] 1) mixing bamboo willow bark powder with water, the obtained feed liquid is continuously extracted by ultrasonic countercurrent, solid-liquid separation, and bamboo willow bark water extract and bamboo willow bark residue are obtained;
[0025] 2) Concentrating and drying the water extract of bamboo willow bark to obtain the water extract of bamboo willow bark.
[0026] In the present invention, the preparation method of bamboo willow bark powder is preferably obtained by natural drying, crushing, sieving and microwave drying of bamboo willow bark. The crushed particle size is preferably 30-50 mesh, more preferably 40 mesh. The...
Embodiment 1
[0043] Step 1, bamboo willow bark is dried, pulverized, and a 40-mesh sieve is used to make bamboo willow bark powder.
[0044] Step 2. Take 1T of bamboo willow bark powder, use deionized water as solvent, and use ultrasonic countercurrent continuous extraction equipment to extract at 65°C. After extraction, go through decanter centrifugation at 2500rpm, and then go through butterfly centrifugation at 2500rpm. 7000rpm, after centrifugation to obtain the extraction filtrate.
[0045] Step 3, concentrating the filtrate to a specific gravity of 1.05 to obtain an extract.
[0046] Step 4, the extract enters the spray dryer, the air inlet temperature is 180° C., and the outlet air temperature is 60° C. to obtain dry powder of willow bark extract monomer preparation.
[0047] Step 5. After mixing the filter residue and pine sawdust according to the mass ratio of 2:1, add tap water and a starter to make the mixture have a water content of 60%. Add 200gEM probiotics to each 1000kg of...
