Embodiment 1
[0021] (1) Preparation of reed vinegar:
[0022] Utilize pyrolysis process, put the reed raw material with water content 15% (by weight) in the reaction kettle of 500 ℃ and heat under the condition of air isolation for 6 hours, the gas that is pyrolyzed is condensed with circulating water to obtain reed crude vinegar liquid, The tar will float on the surface of the liquid after the reed crude vinegar is left to stand for a few days, and the tar will be removed by using a container. After the tar-removed reed crude vinegar was left to stand for 5 months, a clear liquid from turquoise, yellowish brown to dark green was obtained, which was the reed vinegar for later use.
[0023] Reed vinegar is a mixture of various complex components, the main component is water (about 90%), followed by organic acids (about 2%), phenols (about 2%), ketones (about 2%), Aldehydes (about 2%), alcohols (about 0.2%) and other natural organic substances.
[0024] (2) Compounding of liquid fertilizer...
Embodiment 2
[0033] The raw material formula is 1 L of reed vinegar, 60 g of urea, 80 g of potassium dihydrogen phosphate, 30 g of magnesium sulfate, 15 g of ferric sulfate and 6 g of EDTA, and the rest is the same as in Example 1.
Embodiment 3
[0035] If the liquid fertilizer is mainly used as a foliar spray, it is also necessary to add surfactant Tween80 according to the formula.
[0036] Add surfactant Tween80 (Tween-80) in the liquid fertilizer obtained in embodiment 1, addition is 2ml / l, stir gently and make it fully dissolve and get final product (surfactant also can be selected other types, addition amount Add as required) to get another liquid fertilizer.
[0037] The obtained liquid fertilizer added with surfactant is cooled and stored statically, and the prepared liquid fertilizer is placed in an environment protected from light and at normal temperature.
[0038] Prove through experiment, the use effect of the present invention is as follows:
[0039] 1, the impact of gained seedling raising liquid fertilizer on tomato and celery seedling raising process in the embodiment of the present invention 1:
[0040] During tomato and celery seedling cultivation, when 2-3 true leaves appear, dilute the prepared li...
