Abstract

The present invention provides a kind of special fertilizer product of dendrobium candidum, is made up of each raw material composition with following parts by weight：Take 5~25 parts of bark, sequentially add 5~15 parts of gel particle, 0~20 part of wood chip, fresh 0~20 part of tongue, the special fertilizer product of dendrobium candidum is obtained after being stirred；The gel particle is that starch is gelatinized through high temperature, adds acrylic acid, catalyst and crosslinking agent, and reaction solution is obtained after room temperature reaction, add bacillus subtilis fermentation liquor and activated carbon granule, after stirring in low-temperature air-drying to water content below 20%, rub to 1~5 mesh, obtain gel particle.This law effectively increases the content of organic nitrogen, phosphorus, potassium in dendrobium candidum special fertilizer using microbial fermentation mode, and and can completely avoid the discharge of waste water and waste residue.Cellulose and lignin in paulownia shell are made full use of, the high potassium material of paulownia shell is made full use of, is converted into activated carbon, be easy to adsorb substantial amounts of organic matter, slowly release organic nitrogen, phosphorus, potassium are reached under the influence of gel, turn avoid the loss of nutrient in fertilizer.It is water absorbent gel particle directly to utilize Starch Conversion in plant root tuber, and organic matter and activated carbon are fixed in gel, reduces the production cost of fertilizer, has reached the purpose of fertilizer water conservation itself again.

Description

A kind of special fertilizer product of dendrobium candidum

Technical field

The present invention relates to a kind of dedicated fertilizer preparation method of cultivation of dendrobium officinale, belong to organic fertilizer manufacturing technology field.

Background technology

Dendrobium candidum, it is classical in the Tang Dynasty medical science《Taoist Scriptures》In, dendrobium candidum is listed in " first of Chinese nine big celestial grass ", from Tang Since Song, royal tribute has been listed in always.Dendrobium candidum is born in height above sea level up on the dark and damp rock in 1600 meters of mountain region half, and happiness is warm The environment of moist climate and half cloudy half light, can not resist cold.Because growth cycle is slow, it is extremely difficult to survive, dendrobium officinale is endangered. Last century the eighties, dendrobium candidum treasure Endangered Medicinal Herb by what country was classified as focused protection.《Chinese Pharmacopoeia》：Beneficial stomach life Tianjin, nourishing Yin and clearing heat.The tender stem of a small number of kinds such as dendrobium candidum, is twisted into helical form or spring-like, dries, and commodity are referred to as earrings stone Dry measure used in former times, also known as maple bucket.

Stem is upright, cylinder, long 9-35 centimetres, thick 2-4 millimeters, not branch, tool more piece, 1-3-1.7 centimetres of internode length, often In middle part 3-5 pieces of leaf of above alternate；Ye Erlie, papery, long round shape lanceolar is long 3-4 centimetres, wide 9-11 millimeters, and tip is blunt simultaneously And how many hook turn, base portion is downward to embrace the sheath of stem, and edge and middle rib are often with lavender；Leaf sheath often with purple plague purpura, when old its upper limb with Stem pine from and open, and with section leave 1 ashen gap of ring-type.Raceme is often sent from the old stem top for having fallen leaf, Have 2-3 flower；The long 5-10 millimeters of common peduncle, base portion have 2-3 pieces short sheath；Rachis inflection sigmoid, it is long 2-4 centimetres；Petal piece Dry film matter, shallow white is avette, long 5-7 millimeters, and tip is slightly blunt；Bennet and ovary are long 2-2.5 centimetres；Sepal and petal yellow green, Nearly similar, long round shape lanceolar, 1.8 centimetres are about, wide 4-5 millimeters, the sharp point of tip, has 5 arteries and veins.Side sepal base portion is broader, It is wide about 1 centimetre；Calyx capsule cone, 5 millimeters are about, end is circular；Lip white, base portion have the corpus callosum of 1 green or yellow, Ovum shape lanceolar, middle part reflexed more slightly shorter than sepal, the anxious point of tip, do not split or unobvious 3 are split, the tool aubergine of both sides below middle part How much wavy striped, edge be；Lip disk gathers the hair of thin papillary, and has 1 aubergine patch more than middle part；Stamen post is yellowish green Color, 3 millimeters are about, tip both sides respectively have 1 purple point；Stamen post foot yellow green band aubergine striped, thinly covered hair；Anther cap white is long Ovate triangle, 2.3 millimeters are about, the nearly sharp point in top and 2 are split, the month at florescence 3-6.

Wild dendrobium candidum is typically grown between height above sea level 100-3000 rice height, is often grown nonparasitically upon another plant in tree above or on rock, Like warm.Moistening and half shade environment, can not resist cold.18~30 DEG C of thermophilic is grown, growth period is with 16~21 DEG C of more particularly suitable, rest periods 16~18 DEG C, evening temperature is 10~13 DEG C, and the temperature difference is maintained at 10~15 DEG C most preferably.Day temperature grows more than 30 DEG C to the stem of noble dendrobium Influence less, winter temperature is not less than 10 DEG C.Seedling is easily endured cold below 10 DEG C, requires harsh to the environmental condition of growth. The natural propagation ability of wild iron sheet is low, the speed of growth is slow, has forbidden plucking at present.Although the property function hat of dendrobium candidum First of coping stone dry measure used in former times, but the dendrobium candidum to circulate in the market, all it is artificial cultivar substantially.
