Embodiment

[0035] Example Preparation of slow-release compound seaweed fertilizer containing garlic extract

[0036] S1. Preparation of Garlic Extract

[0037] (1) Weighing fresh mature garlic bulbs, crushing and crushing to obtain garlic pulp;

[0038] (2) Add 1 mass times of absolute ethanol to the garlic pulp, extract at 20°C for 6 hours, filter to obtain the filtrate and filter residue, leaching the filter residue with 1 mass times of absolute ethanol at 20°C for 8 hours, filter again to obtain the filtrate, and combine Obtain about 1100 mL filtrate;

[0039] (3) Distill the filtrate under reduced pressure to remove the organic solvent and then filter again, the filtrate is the garlic extract.

[0040] S2. Preparation of Seaweed Extract

[0041] (1) Wash the leftovers of fresh kelp to remove impurities, dry them at 70°C until the water content is lower than 10% wt, and crush them to pass 300 mesh to obtain seaweed powder;

[0042] (2) Weigh 0.5 kg of seaweed powder and add 5-10 t...

Abstract

The invention belongs to the technical field of soil fertilizers, and provides a slow-release composite seaweed fertilizer containing a garlic extract. The composite seaweed fertilizer comprises, by weight, 10-15 parts of the garlic extract, 13-15 parts of a seaweed extract, 10-15 parts of 1250-1500-mesh diatomite, 6-8 parts of polyferric silicate sulfate, 2-4 parts of medical stone powder, 10-12 parts of humic acid, 5-8 parts of carboxymethyl chitosan, 5-6 parts of hydroxypropyl methyl cellulose, 4-5 parts of konjac glucomannan and 3-5 parts of wintergreen oil. According to the prepared compound seaweed fertilizer, double coating is formed on nutrients by using the diatomite and the slow-release coating agent, the nutrients are not easy to lose, the fertilizer efficiency is more lasting, the nutrients required by growth of crops at all stages can be met, the ecological environment of soil is not damaged, and the composite seaweed fertilizer is a novel green and efficient compound fertilizer, can remarkably improve the yield and quality of crops in practical application, and increases the economic benefitd.

Description

technical field [0001] The invention belongs to the technical field of soil fertilizer and relates to a slow-release compound seaweed fertilizer containing garlic extract. Background technique [0002] Garlic extract as a new biopesticide and seaweed fertilizer as a new biofertilizer have the characteristics of broad antibacterial spectrum, low dosage, high value, safety and environmental protection in plant protection and nutrition. They are the best choice for the development of precision agriculture, irrigation agriculture and pollution-free agriculture. The preferred product, very suitable for the current needs of sustainable agricultural development. [0003] Garlic extract, as a plant-derived agent, has biological activities such as antibacterial and bactericidal, promoting plant growth, and enhancing plant stress resistance and adaptability. Seaweed fertilizer refers to the natural multi-effect plant fertilizer with seaweed extract as the active ingredient. It is ric...
