Problems solved by technology

[0003] In the research on seaweed fertilizer in recent years, the seaweed fertilizer is mainly prepared in the form of seaweed extract, and the method of obtaining it is mostly the extraction of chemical reagents, and the loss of active substances is relatively large.
However, there are very few studies on the use of microbial fermentation to obtain seaweed organic fertilizers, and there is no related research on the coating of seaweed organic fertilizers

Embodiment 1

[0031] The first is the preparation of the extract of physiologically active substances from seaweed, specifically: wash the collected kelp to remove impurities, divide it into multiple parts, each part is 1000kg, press and crush it into small pieces of about 3cm, add 5000kg to each of the I pool and II pool For fresh water, first soak the kelp in pool I for 60 minutes (the time is too short, not enough to soak out the active substances, and the time is too long, which increases the water absorption of the kelp, thereby increasing the recovery rate of the active substances, and the leaching rate of 60 minutes can reach 85% , the highest can reach 94%), the soaking water in pool I is filtered out and concentrated, the kelp is controlled and transferred to pool II, submerged again for 60 minutes, the kelp is taken out for the next step of fermentation, new water is added to pool I, and enough water is added to pool II In fresh water, the next batch of kelp is soaked in pool II fo...

Embodiment 2

[0035] The first is the preparation of the extract of physiologically active substances from seaweed, specifically: wash the collected Enteromorpha to remove impurities, weigh multiple portions, each portion is 1000kg, press and crush it into small pieces of about 3cm, each of the I pool and II pool Add 5000kg of fresh water, first soak Enteromorpha in Pond I for 80min, (according to the physical characteristics of seaweed, the soaking time can be extended to 80min appropriately), filter out and concentrate the soaking solution, add 5000kg of fresh water to Pond I, and transfer the kelp to Pond I Immerse pool II again for 80 minutes, add enough fresh water to pool II, exchange the functions of pool I and pool II, repeat this process, concentrate the leachate for later use; hydrolyze the soaked enteromorpha at 60°C under the condition of pH 3.0 (adjusted with hydrochloric acid) After 6 hours, the hydrolyzate was centrifuged at 4000 rpm / min for 5 minutes, the supernatant was comb...

Abstract

The invention provides a chitosan coated alga bioorganic fertilizer and a preparation method thereof. The chitosan coated alga bioorganic fertilizer is obtained by adopting a process combining high efficiency physical fragmentation with a chemical processing technology to extract physiological active substances and nutrients of algae, adding zymocytes with the synergism to alga residues, preparing an alga organic fertilizer in an aerobic fermentation mode, adding proper amounts of nitrogen phosphorous potassium, trance elements and functional bacteria, mixing alga extracts with the alga organic fertilizer, freeze-drying, and spraying the obtained alga bioorganic fertilizer with chitosans and a sodium alginate solution. The organic fertilizer which contains various biological growth promoters can improve utilization rates of the nutrients by crops and increase endurances and validities of effective components, and also can increase ventilation and coalescence capabilities of soil, obviously promote the formation of granule structures of the soil, slowly release the nutrients, satisfy demands of plants of different growth stages, and generate obvious positive effects on the crop maturation, output and quality improvements, disease and insect pest resisting and the like.

Description

technical field [0001] The invention relates to a fertilizer and a preparation method thereof, in particular to a chitosan-coated seaweed biological organic fertilizer and a preparation method thereof. Background technique [0002] Seaweed is a low-level cryptogamous plant that grows in the ocean. Due to its special growth environment, its nutritional composition is very different from that of land plants. Seaweed contains rich mineral elements and vitamins that cannot be compared with general land plants. Seaweed fertilizer has been used as an important liquid surface spraying agent in recent years. It has been applied to many crops, including many grasses, grains, flowers and vegetable varieties, and has achieved good effects such as disease resistance, yield increase and efficiency increase. The positive effect of seaweed fertilizer on crop yield and quality as well as health comes from the synergy of 4 main substances in seaweed: carrageenan, plant hormones, amino acids ...
