Roots induced by the rooting powder are long and thick and strong, and roots are tidy. By adding corncob, wood chip and the like, soil is provided with organic matter. By adding natural plant raw materials, proton for acidolysis of soil minerals is also provided to participate in weathering and formation of soil minerals to change surface chemical property. Thus, availability for plants is enhanced. By adding calcium ammonium nitrate, available nutrients in soil are further enriched, thus playing a positive role in cultivating fertile soil and promoting plant development.

Composite type plant rooting powder
The invention discloses composite type plant rooting powder. The composite type plant rooting powder is prepared from the following raw materials in parts by weight: 3-5 parts of sodium borate, 43-46 parts of distillers' grains, 40-42 parts of straw fibers, 5-8 parts of talcum powder, 4-6 parts of potassium sulfate, 15-19 parts of maple syrup, 24-28 parts of potassium humate, 2-4 parts of ferrous sulfate, 26-30 parts of green hawthorn fruits, 35-39 parts of fresh smoked plum, 72-75 parts of chaenomeles speciosa, and a proper amount of water. The composite type plant rooting powder is reasonable in component proportion, and high in rooting rate and seedling rate; added chelating ions such as sodium borate and ferrous sulfate can participate in plant in-vivo chlorophyll synthesis, oxidation-reduction reaction in cells, an electron transfer process, and plant respiration, and can promote a plant growth center to transfer to a root system, so that the growth and development of the root system are stimulated, the nutrition absorption capacity of plants is increased, and the plant quality is improved.
