Chinese patent (application number 201310603775.3) discloses a method of multi-bacteria co-fermentation of seaweed to prepare functional seaweed fertilizer. In this patent, Bacillus licheniformis, yeast, lactic acid bacteria and actinomycetes are added to the seaweed powder system for fermentation, and then dried at low temperature Pulverize and prepare functional seaweed fertilizer. This method mixes the metabolites of various bacteria together. The product may have certain effects, but there may be substances that inhibit each other and antagonize each other in the various metabolites. If they are not separated, they are mixed. together, may reduce its efficacy
From the above-mentioned problems, it can be seen that there is still no breakthrough in seaweed fertilizers with obvious functions, especially drought resistance.

Abstract

The invention discloses a seaweed liquid fertilizer with a drought resisting function and a preparation method and application of the seaweed liquid fertilizer. The seaweed liquid fertilizer comprisesthe following components: a seaweed drought resisting functional carrier, external drought resisting substances, humic acid, chemical fertilizers and a surfactant, wherein the seaweed drought resisting functional carrier is prepared by implementing activity maintenance treatment on an extract prepared from fresh seaweeds through enzymolysis and mycogenic composition in sequence, implementing molecular membrane grading separation and by implementing drought resisting activity detection screening on crop seedlings. The preparation method comprises the following steps: uniformly mixing the seaweed drought resisting functional carrier and the external drought resisting substance, compounding with the humic acid and the chemical fertilizers in sequence, and finally adding the surfactant and the like, thereby obtaining the seaweed liquid fertilizer. The seaweed liquid fertilizer disclosed by the invention is convenient to transport, can be applied to roots of crops and leaves as well, can be used with drip irrigation systems in large-size planting areas, and is very applicable to water-fertilizer integral systems. Large field drought testing results show that by adopting the seaweed liquid fertilizer, the yield of Chinese flowering cabbage can be remarkably increased by 14.7-19.8% when being compared with that of Chinese flowering cabbage with a conventional fertilizer.

Description

technical field [0001] The invention relates to the technical field of fertilizer production, in particular to a seaweed liquid fertilizer with drought resistance function and its preparation method and application. Background technique [0002] Drought is one of the most serious limiting factors in agricultural production. Drought or seasonal drought can result in reduced crop yields and reduced quality of agricultural products. Under drought stress, the content of plant auxin and gibberellin decreased significantly, and the content of ABA increased, which accelerated tissue aging and shedding; at the same time, drought stress also induced the accumulation of active oxygen free radicals, resulting in the oxidation of cell membrane proteins, resulting in membrane lipid hyperactivity. oxidation. In response to drought stress, crops have formed a whole set of drought resistance mechanisms, such as active accumulation of certain amino acids (such as proline), amino acid deriva...
