Embodiment 1

[0027] (1) Preparation of lactic acid bacteria fermentation broth

[0028] Prepare solid agar plate medium: 1 part of tryptone, 0.5 part of yeast extract, 0.5 part of sodium chloride, 1 part of agar, 800 parts of water, add each component to a boiling water bath, mix and heat to melt, add NaOH to adjust pH to 7, filtered, bottled and sealed, then placed in a high-pressure steam sterilizer, 0.8kg / cm 2 , 115°C, sterilized by moist heat for 15 minutes, poured into a plate aseptically, and cooled to room temperature to obtain a solid medium.

[0029] Preparation of liquid medium: Take 10 parts of starch, 10 parts of beef extract, 10 parts of peptone, 4 parts of NaCl, and 1000 parts of water; add them to a boiling water bath, mix and heat to melt, add NaOH to adjust the pH to 7, filter, bottle and seal Put it in a high-pressure steam sterilizer, 0.8kg / cm 2 , 115°C, sterilized by moist heat for 15 minutes, and cooled to room temperature to obtain a liquid medium.

[0030] The pre...

Embodiment 2

[0034] Get the lactic acid bacteria fermented liquid concentrate 55Kg of embodiment 1, then get calcium chloride 1.5Kg, magnesium sulfate 1.5Kg, ferrous sulfate 1.5Kg, cesium zinc borate 0.6Kg, bismuth molybdate 1Kg, basic copper tartrate 0.21Kg, Manganese sulfate 0.11Kg, humic acid 1.5Kg composition, fully mixed, adjust the pH value of the liquid fertilizer to 6-7. When used, it is diluted 1000-2000 times with agricultural water, adjusted to pH 7 with 1% HCl, and can be directly applied to foliage fertilizer for spraying.

Embodiment 3

Abstract

The invention belongs to the field of agriculture, relates to a liquid fertilizer and particularly relates to a mixed liquid fertilizer containing a lactic acid bacteria fermentation liquid, multiple trace elements, humic acid and the like. Specifically, the liquid fertilizer containing the lactic acid bacteria fermentation liquid is prepared from the lactic acid bacteria fermentation liquid, calcium chloride, magnesium sulfate, ferrous sulfate, zinc borate cesium, bismuth molybdate, alkaline cupric tartrate, manganese sulfate and the humic acid. The liquid fertilizer can be sprayed as a leaf fertilizer, and has the advantages of being stable in fertilizer efficiency, abundant and complete in trace elements, abundant in material source, low in price, environment-friendly and convenient to transport, so that the usable area is large.

Description

technical field [0001] The invention belongs to the field of agriculture and relates to a liquid fertilizer, in particular to a mixed liquid fertilizer composed of lactic acid bacteria fermentation broth, various trace elements, humic acid and the like. Background technique [0002] Lactic acid bacteria fermentation liquid is the discarded liquid part in the process of liquid fermentation of lactic acid bacteria, which is rich in polypeptides, certain antibiotics, active enzymes, etc., and can prevent and control various diseases and insect pests. The bacteria sludge obtained by filtering the liquid is dried to obtain the bacteria powder, and the filtrate is used as sewage for subsequent treatment, which wastes resources and financial resources. In addition, the lactic acid bacteria fermentation liquid contains various water-soluble nutrients and rich organic matter. These organic matter not only have fertilizer effect, but also are conducive to the activity of soil microorg...
