Compound plant ash dendrobium seedling culture medium material and preparation method and application thereof

Abstract

The invention relates to a compound plant ash dendrobium seedling culture medium material and a preparation method and application thereof. The preparation method comprises the steps of: mixing plant ash with plant hormone such as brassinolide, naphthylacetic acid and chlormequat chloride, adding calcium nitrate, adding ammonium nitrate and evenly agitating to prepare powder compound plant ash; and adding water into the powder compound plant ash, keeping the humidity to be 12-20 percent, evenly mixing and pressing the compound plant ash into columnar materials to obtain the formed compound plant ash. The powder compound plant ash and the formed compound plant ash are used for dendrobium seedling culture. The compound plant ash is a high-efficacy fertilizer, the effect of slow release can be achieved at the same time, the fertility can be maintained more effectively, the compound plant ash is also a high-quality slow-release fertilizer, not only can ventilation be guaranteed, but also an excellent environment is provided for the growth of dendrobium seedlings through an upper layer and a lower layer, the growth of the dendrobium seedlings is promoted, the yield is improved, and the compound plant ash is particularly suitable for plants such as dendrobium which grow slowly and have harsh requirements on planting environments.

Description

[0001] technical field [0002] The invention relates to a composite plant ash dendrobium seedling raising matrix material prepared by using compound plant ash as well as its preparation method and application. Background technique [0003] Plant (herbaceous and woody plants) residues after burning, called plant ash. Plant ash fertilizer Because plant ash is the ashes of plants after burning, plant ash contains almost all the mineral elements contained in plants. Among them, potassium is the most abundant element, generally containing 6-12% potassium, of which more than 90% is water-soluble and exists in the form of carbonate; followed by phosphorus, generally containing 1.5-3%; it also contains calcium, magnesium, silicon, Sulfur and iron, manganese, copper, zinc, boron, molybdenum and other micronutrients. Plant ash contains about 5%--15% potassium, of which 80%-90% is water-soluble potassium, which is easily absorbed and utilized by crop roots, and is also rich in nitr...
