Embodiment 1

[0049] Embodiment 1: A kind of new application of seaweed as a plant growth regulator, the whole algae, algae powder or auxin extract of a kind of plant in Gracilaria or Sargassum in large seaweeds are used as a plant growth regulator, and are cultivated in seedlings , fruit tree cultivation and laboratory plant cultivation.

[0050] Among the above application methods:

[0051] 1. Use the above-mentioned whole algae as a plant growth regulator to directly bury the roots of plants or wrap the roots of plants.

[0052] 2. Mix the above-mentioned algae powder with soil or spread it on the roots of plants as a plant growth regulator. Among them, the production process of seaweed powder:

[0053] Fresh seaweed→washing in fresh water→drying→crushing→seaweed powder.

[0054] The suitable season for collecting wild macroalgae is early summer to autumn. Fresh seaweed must be cleaned; when cleaning, soak it in fresh water three times, half an hour each time; drain the water and the...

Embodiment 2

[0069] Embodiment 2: A kind of new application of seaweed as plant growth regulator, the whole algae, algae powder or plant growth kinetin extract of two kinds of plants of Gracilaria and Sargassum in large seaweed are used as plant growth regulator, and are cultivated in nursery stock, Application in fruit tree cultivation and laboratory plant cultivation.

[0070] Among the above application methods:

[0071] 1. Use the above-mentioned whole algae as a plant growth regulator to directly bury the roots of plants or wrap the roots of plants.

[0072] 2. Mix the above-mentioned algae powder with soil or spread it on the roots of plants as a plant growth regulator. Wherein, the production process of the seaweed powder is the same as the first embodiment, but the seaweeds of different varieties are classified and pulverized and then evenly mixed to adjust the nutritional content of the seaweed powder.

[0073] 3. Use the above-mentioned auxin extract as a plant growth regulator...

Abstract

Disclosed is the novel use of sea weed as plant growth regulator characterized in that, using full algae or algae powder of one or more of Gracilaria verrucosa genus and gulfweed genus plants in large-scale sea weeds or plant growth hormone extract as plant growth regulator, which can be used in nursery stock cultivation, fruit tree cultivation and laboratory plant incubation. The Gracilaria verrucosa genus and gulfweed genus seaweed contains a great amount of cell activator, auximone, auxin, oxyneurine, heteroauxin and other natural active constituents.

Description

technical field [0001] The invention relates to a use of large seaweed, in particular to a new use of the large seaweed as a plant growth regulator in the process of plant growth. Background technique [0002] There are no fewer than 3,000 species of large marine algae. Because seaweed contains a variety of amino acids, vitamins, minerals and a large number of organic compounds such as mannitol, alginate and protein, and is extremely rich in resources, has high nutritional value, strong adaptability, easy breeding, and low processing cost. Therefore, it is often used in food and feed. The medicinal and edible history of seaweed dates back to 3000 BC. The famous Chinese medical scientist Shen Nong once described the benefits of seaweed in his book. Greek and Roman literature also mentions the nutritional and medicinal properties of certain algae. In fact, the development and utilization of seaweed resources has been a subject of concern for a long time. Every year, govern...
