Abstract

The invention provides a biological seaweed fertilizer. The biological seaweed fertilizer is obtained by culturing a seaweed water extracting solution and a bacterial solution, wherein the bacterial liquid comprises halomonas, shewanella, Marinobacter, pseudomonas and nitrate reducing bacteria. Compared with the prior art, the microbial preparation is added into the seaweed water extracting solution for culture, plants can be promoted to absorb nutrient substances in the seaweed water extracting solution, then the quality of fruits and vegetables is improved, the content of soluble solids andVC is increased, fruit coloring is promoted, and the salt tolerance of the plants is improved; the preservation time of the biological seaweed fertilizer can be prolonged, and tropical agricultural areas are convenient to use.

Description

technical field [0001] The invention belongs to the field of agricultural biotechnology and fertilizer technology, and in particular relates to a biological seaweed fertilizer and a bacterial liquid for biological fertilizer and a preparation method thereof. Background technique [0002] The unreasonable use of a large number of chemical fertilizers has caused many environmental problems such as soil damage and water pollution, which poses a great threat to the sustainable development of agriculture. Therefore, the development and utilization of environment-friendly bio-fertilizers has become an issue of concern to the world's major agricultural countries, especially China, a developing country with a large population. Among them, biofertilizers such as products containing live microorganisms or natural compounds derived from organisms such as microorganisms or algae, which can improve soil chemical and biological properties, restore soil fertility, and increase crop yields ...
