Example Embodiment
[0017] Example 1 (refer to the raw materials and weight parts corresponding to Example 1 in the table):
[0018] Take 50 parts by weight (the same below) of biogas slurry concentrate, mix 20 parts of urea, 15 parts of KH 2 PO 4 , 1 part CaCl 2 , 2 parts MgSO 4 ·7H 2 Put O into the biogas slurry to dissolve and mix thoroughly, then add 1 part of FeCl 3 ·6H 2 O, 0.8 parts of ZnSO 4 ·7H 2 O, 0.5 parts of H 3 BO 3 , 0.4 parts (NH 4 ) 6 Mo 7 O 24 ·4H 2 O, 0.2 parts CuSO 4 ·5H 2 O, 0.1 part of MnCl 2 ·4H 2 O, 3 parts of citric acid (monohydrate) and 1 part of ascorbic acid were separately mixed into the solution, and 1 part of surfactant polysorbate 80, namely Tween 80, was added, and mixed thoroughly to make a liquid fertilizer stock solution, and then use the stock solution weight Dilute with 500-1000 times industrial water, use 1% H 2 SO 4 Or adjust the pH to 6 with 1% HCl to become the nutrient solution for soilless culture. Consider Cl - Excessive presence of ions in the soil is un...
Example Embodiment
[0019] Example 2 (refer to the corresponding raw materials and weight parts of Example 2 in the table):
[0020] Take 80 parts of biogas slurry concentrate, then mix 30 parts of urea, 25 parts of KH 2 PO 4 , 3 parts CaCl 2 , 40 parts MgSO 4 ·7H 2 O were put into the biogas slurry to fully dissolve and mix, and then 1.5 parts of FeCl 3 ·6H 2 O, 1 part of ZnSO 4 ·7H 2 O, 1 part H 3 BO 3 , 0.7 parts (NH 4 ) 6 Mo 7 O 24 ·4H 2 O, 0.3 parts CuSO 4 ·5H 2 O, 0.2 parts MnCl 2 ·4H 2 O, 5 parts of citric acid (monohydrate) and 5 parts of ascorbic acid are respectively mixed into the solution, and finally 5 parts of surfactant polysorbate 80 parts (Tween 80) are added, mixed thoroughly, and then made into liquid fertilizer stock solution, and then used The weight of the stock solution is diluted with industrial water of 1000-2000 times, and the pH is adjusted to 7 with 1% HCl to become a foliar fertilizer that can be directly applied for spraying.
Example Embodiment
[0021] Example 3 (refer to Example 3 in the table for the corresponding raw materials and their parts by weight value):
[0022] Take 65 parts of biogas slurry concentrate, then mix 25 parts of urea, 20 parts of KH 2 PO 4 , 2 parts CaCl 2 , 3 parts MgSO 4 ·7H 2 O were put into the biogas slurry to fully dissolve and mix, and then 1.2 parts of FeCl 3 ·6H 2 O, 0.9 parts of ZnSO 4 ·7H 2 O, 0.7 parts of H 3 BO 3 , 0.55 parts (NH 4 ) 6 Mo 7 O 24 ·4H 2 O, 2.5 parts CuSO 4 ·5H 2 O, 1.5 parts MnCl 2 ·4H 2 O, 4 parts of citric acid (monohydrate) and 3 parts of ascorbic acid are respectively dissolved in the solution, and 3 parts of surfactant polysorbate 80, namely Tween 80, are added, and mixed thoroughly to prepare a liquid fertilizer with a pH of 7-8.5 Stock solution, short-term storage for future use. Temporarily dilute and adjust the pH to 6.5 when needed. Although most of the commonly used chemical fertilizers and organic fertilizers are alkaline fertilizers, most of the elements in ...
