Composite microbial functional liquid fertilizer for dendrobe

Abstract

The invention discloses a composite microbial functional liquid fertilizer for dendrobe. The composite microbial functional liquid fertilizer is prepared from the following components in parts by weight: 4.0-4.1 parts of macroelements, 0.035-0.04 part of microelement, 0.05-0.08 part of iron salt chelate, 0.12-0.18 part of organic matters, 10-30 parts of microbial fermentation liquid and 950-990 parts of water. The composite microbial functional liquid fertilizer for the dendrobe contains microbial flora beneficial to plant growth, also contains balanced macroelements, microelements, pure natural biological factor, chelate and vegetable jelly, is capable of providing small and easy-to-absorb growth nutrients and forming a gelatinous membrane on the leaf surface, has water-holding and anti-burning effects and also has the function of inhibiting harmful microbes; use of a chemical antibacterial agent is avoided; the growth speed and the product quality of dendrobium officinale are greatly improved; and meanwhile, the composite microbial functional liquid fertilizer has the function of improving the activity of beneficial microelements of the soil.

Description

technical field [0001] The invention belongs to the technical field of compound microbial fertilizer, and in particular relates to a compound microbial functional liquid fertilizer for dendrobium. Background technique [0002] Dendrobium candidum is a precious food for health care of traditional Chinese medicine. It grows slowly in the natural environment and is expensive. Wild dendrobium has been excavated and is on the verge of extinction. As people realize the value of Dendrobium candidum, people are trying to cultivate it artificially. Because Dendrobium officinale is difficult to survive in soil, it is suitable for planting on air-permeable substrates or tied to trees, and the root system loses the conditions for absorbing and utilizing natural mineral ions in the soil. Therefore, foliar fertilization has become the main fertilization for Dendrobium and non-soil cultivated plants Way. At present, there is no special fertilizer for Dendrobium for sale in the market.

Problems solved by technology

[0003] In summary, for the artificial cultivation characteristics of Dendrobium plants, there are the following problems: (1) The root system of Dendrobium plants cultivated with artificial ventilation is not like other plants that can absorb water and fertilizer normally in the soil, and the growth rate is very slow, which affects market supply and demand Balance; (2) the inorganic and organic fertilizers currently available on the market for dendrobium are not special-purpose fertilizers. Some foliar fertilizers have large molecular weights, or have a short adhesion time on the plant surface, which is not conducive to absorption and long-term fertilizer supply, which is not good for growth; ( 3) At present, commercially available fertilizers do not have the function of biological pest control and anti-bacteria, and chemical reagents are required, which is easy to produce harmful residues
