Description

technical field [0001] The invention relates to a compound fertilizer for dendrobium candidum, belonging to the technical field of fertilizer preparation. Background technique [0002] Dendrobium candidum, also known as black knot grass, is a perennial epiphytic herb of the genus Dendrobium orchidaceae. The stem of Dendrobium candidum is named for its iron-green skin. It is a precious wild medicinal plant that grows at an altitude of 1600 meters. On the semi-shady rocks in the mountains, it likes a warm and humid climate and a semi-yin and semi-yang environment. It is not cold-resistant, and generally can withstand a low temperature of -5°C. Dendrobium can be divided into dozens of species such as yellow grass, golden hairpin, and horsewhip. Dendrobium is the best product of Dendrobium. Dendrobium candidum has unique medicinal value. Its stems are used as medicine. "Chinese Pharmacopoeia" records that Dendrobium has the effects of nourishing stomach, nourishing yin and clear...

Problems solved by technology

[0003] Dendrobium officinale is rich in nutrients, has high medicinal value and economic value, and has high plantability. Dendrobium officinale is very sensitive to nutrients. At present, when people fertilize Dendrobium officinale, they generally use chemical fertilizers, urea, Feed and other raw materials are used to topdress Dendrobium candidum. Although there is a certain effect, the nutrients contained in chemical fertilizers and urea are far from meeting the nutritional needs of Dendrobium candidum. Due to lack of nutrients, it is easy to cause the leaves of Dendrobium candidum to be yellow, small and grow. Slow, small rhizomes, poor disease resistance, susceptible to leaf spot, more prone to various diseases and insect pests, so how to improve these problems, better meet the nutritional needs of Dendrobium candidum, better make Dendrobium candidum absorb nutrients, To achieve the purpose of promoting the growth of Dendrobium candidum, increasing the output of Dendrobium candidum, and improving the quality of Dendrobium candidum, it is the focus of current research
