[0017] (1) Preparation of kelp slurry: select high-quality fresh kelp or soaked dried kelp, and then clean the soil and dust on the surface. First, it is coarsely powdered by a fresh kelp crusher, and then ground by a homogeneous mixer to form a viscous kelp slurry. , and then added to the microbial fermentation broth as a fermentation substrate for microorganisms.

[0018] (2) Preparation and inoculation of compound microbial culture medium: brown sugar 10-20 g / L, waste molasses 5-10 g / L, protein powder 1-2 g / L, urea 3-5 g / L, sodium chloride 5 g / L, kelp slurry 15-40g / L, inoculum size 5-20%, water 1 L.

[0019] (3) Cultivation and fermentation: In the liquid fermentation process, the liquid fermentation temperature is between 30-35°C, and the fermentation time is 3-5 days. Affected by the temperature and fermentation time, the kelp cell breakage rate is 80% Above, the microorganisms are around 1.2 billion / ml, and the pH is between 3.8-4.0.

Abstract

The invention discloses a production method for preparing seaweed fertilizers with seaweed contents and beneficial microorganisms by microorganism fermentation. According to the method, a certain amount of seaweed serous fluid is added into compound strain liquid culture media, wall breaking of seaweed cells is facilitated by enzyme and acid generated by microorganism metabolism, so that contents of the seaweed cells are released. The production method includes the steps: firstly, crushing fresh seaweeds or soaked seaweeds into coarse powder by the aid of a fresh seaweed crusher; secondly, performing homogeneity on the coarse powder by the aid of a homogeneous mixer; taking homogenized seaweed serous fluid as culture media to add into culture media of compound microorganisms; performing fermentation for 3-5 days at suitable temperature after the microorganisms are inoculate; producing the liquid seaweed fertilizers with the seaweed contents and the beneficial microorganisms. The produced fermentation liquid seaweed fertilizers contain the seaweed contents for adjusting plant growth and also contain a lot of microorganisms for adjusting soil, the transplanted survival rate of various crops can be facilitated, seedling recovering period is shortened, plants can rapidly germinate new root systems, main roots and lateral roots are dense, root hair areas are increased, the various crops can bear more fruits, the fruits and tubers are expanded, yield is increased, and the seaweed fertilizers have wide market prospects and popularization values.

Description

technical field [0001] The invention relates to a production method for preparing liquid seaweed fertilizer by fermenting beneficial microorganisms, and provides a production method for seaweed fertilizer for planting crops containing beneficial microorganisms and seaweed active substances. Background technique [0002] Seaweed fertilizers are usually made from large fast-growing brown algae that grow in the ocean. Through chemical, physical or biological methods, the active ingredients in seaweed are extracted to make fertilizers with active substances and provide nutrients for plant growth. Seaweed fertilizer has developed rapidly due to its comprehensive nutrition, unique efficacy, natural pollution-free characteristics and high cost performance. It is known as the fourth generation of fertilizer after organic fertilizer, chemical fertilizer and biological fertilizer. [0003] The production method of seaweed fertilizer: generally can be divided into chemical hydrolysis m...
