Organic seaweed fertilizer and application thereof used as efficient saline soil conditioner

Abstract

The invention discloses a seaweed fertilizer and an application thereof used as the efficient saline soil conditioner, wherein the seaweed fertilizer is an organic seaweed fertilizer obtained by fermenting and decomposing seaweed industrial wastes through a microaerophilic fermentation technology, or a composite organic seaweed fertilizer obtained by complexing the obtained organic seaweed fertilizer with one or more of wheat bran, straw, traditional Chinese medicine residues, fruit residues, activated sludge and vinasse. The application of the organic seaweed fertilizer is that the organic seaweed fertilizer is used as the base fertilizer or additional fertilizer to be directly applied in saline soil or applied in saline soil along with additives and the dosage is 1-2 tons per mu. Used as the saline soil conditioner, the seaweed fertilizer disclosed by the invention can not pollute the environment, can be used to directly increase the organic matter in soil or increase the organic matter through plants and can activate various beneficial microorganisms in soil, thus plant cell division can be promoted, the photosynthetic efficiency can be increased and the salt resistance and alkali resistance of crops can be enhanced. By using the the seaweed fertilizer, the crumb structure of soil can be promoted and improved, the pore space in soil can be improved, the biological activity of soil can be increased, the buffer property to acid and alkali, nutrient conservation and water conservation of soil can be increased and the production cost is low.

Description

technical field [0001] The invention relates to an organic seaweed fertilizer and its application as a high-efficiency saline-alkaline soil improver. Background technique [0002] Seaweed is a low-level photosynthetic nutrient plant that grows in the ocean and is the original producer of marine organic matter. Because it grows in the special environmental medium of seawater, it not only contains the nutrients that land plants have, but also contains trace elements such as iodine, potassium, magnesium, manganese, titanium and seaweed polysaccharides, which are not found in many land plants. Mannitol, etc. The application of seaweed or seaweed extracts in foreign countries has done comparative experiments on a series of crops, and it has had obvious effects on crops in terms of increasing yield, improving quality, and resisting diseases and insect pests. [0003] At present, scholars at home and abroad mainly conduct research on the utilization of fresh seaweed, and there ar...

AI Technical Summary

Problems solved by technology

The waste residue after extracting sodium alginate, iodine, mannitol and alginate from seaweed contains a large amount of substances that are difficult to decompose and utilize. At present, most seaweed waste residues are treated as industrial waste because they cannot be used in time

This will not only pollute the environment, but also cause a waste of resources
