The main components of seaweed fertilizer

Use Seaweed Fertilizer is a giant ocean algae production and processing or adding a certain amount of NPK and trace elements out of a fertilizer processing. There are a variety of forms, but mainly on the market today: liquid with powder-based, there is a fraction of particle state. Sea kelp contains many substances, algae and seaweed plant growth regulators (hereinafter referred to as SWC) has been studied in the main active substance in the following categories:1 cells, kinetinCells, also known as cytokinin kinetin. It is a physiological activity of a class of purine derivatives. Back in 1969, Jennings on the kelp and other brown algae and red algae in the sand dishes endogenous cellular content and kinetin as plant growth regulator substances was studied. Since then, research in this area reported on the increase. Mooney and Van Steden in 1987 using high pressure liquid chromatography (HPLC) method of analysis of the algae containing mainly t-zeatin, dihydro-zeatin, isopentenyl adenosine purine nucleoside and t-Zeatin Kinetin and other cells. Farooqi Japanese scientists in 1991 once again confirmed using NMR techniques in addition to containing the algae cells also contain Kinetin outside zeatin, zeatin riboside, 6 – (Aminomethyl) purines, etc., and confirmed the activity of these cells kinetin. Marine algae is also considered in the adsorbent, GC-MS technology to prove the growth of Fucus sea water containing 6 – (3 methyl-2 – butene amino) purine. SWC in the cell algae and kinetin can respond to most crops produced, the product of several SWC Kinetin activity in cell tests confirmed this view. Brain KR1973 first time in the SWC products (SM3) in vitro transplantation using carrots, in the SWC and without cells containing only kinetin medium for biological testing, experiments show that a high level of cellular activity of kinetin, kinetin and even cell at very low concentrations can also produce strong physiological response. Currently, through the identification and analysis of biological instruments have proved the SWC products contain kinetin cells. The early work of William estimate SWC product Maxicrop kinetin in the activity of the cells is 25 ~ 200 mg / L, Algifert is 10 ~ 500 mg / L, SM3 is 15 ~ 150 mg / L. Blunden and Wildgoose using radish leaf bioassay method in SM3 cells confirmed the activity of kinetin equivalent to 125 mg / L. Other scientists have also confirmed that the South African kelp products Kelpak 66 with properties similar to zeatin (Zeatin, N isopentenyl adenine) of the material. Stable isotope dilution mass spectrometry (Mass spectrometric stable isotope dilution method) were determined Seasol, this commercial product containing SWC t-zeatin, t-zeatin riboside, isopentenyl adenosine and other concentration cells Kinetin glycosides.2 auxinPrevious studies have shown that auxin to stimulate root development and crop the role of cold. Cutting plants, it can greatly improve survival after treatment. The most common plant auxin is indole acetic acid (Indole-3-acetic acid, IAA). Many algae itself contains auxin and auxin type (Auxin and Auxin-like compounds). Van Overbeek early in 1940 announced the indole acetic acid exists widely in a variety of seaweed. Subsequently, Abe H. and Jacobs, respectively in 1972 and 1985 using GC-MS technique Caulerpa, Sargassum, seaweed and other algae in the indole acetic acid (IAA) and the other two categories auxin, phenylacetic acid ( Phenyi-3-acetic acid) and hydroxy acid (Hydroxyphenyl acetic acid) of the structure and content were confirmed. NMR technique to detect algae contain jagged 3 (hydroxy acetyl) indole. As the SWC products can produce a wide range of crop physiological responses, so people speculated that it might be more than one plant growth regulator substances present in the SWC products. This led to carefully test the product in the SWC auxin. Using HPLC and GC-MS technique to analyze the activity of fragments of SWC products, found that some of the SWC products in addition to containing IAA, but also contains indole carboxylic acid (ICA), N, N-dimethyl-B-indolyl ethylamine, indole acetaldehyde (IAId), isoindole and 1,3 – indole (N-hydroxy ethyl benzene o-imide) and so on. Use of GLC and GC-MS was measured by the product of two SWC IAA content were 50 mg / g (dry weight) and 6.63 μg / g (dry weight). Previous studies have shown that auxin to stimulate root development and crop the role of cold.
