Utilization of Wild Organic Fertilizer Resources Eupatorium adenophorum

Eupatorium adenophorum is a perennial herb belonging to the genus Kejue, native to Mexico and introduced to Yunnan via Myanmar prior to liberation. At present, it is distributed in most parts of Yunnan Province and is used as a wild organic fertilizer resource. First, the main features (a) containing nutrients Eupatorium adenophorum contains nitrogen, phosphorus, potassium, calcium, magnesium, iron, sulfur, silicon, copper, zinc, manganese, boron, molybdenum and other crops need nutrients, is a Very good wild organic fertilizer. It was determined that E. adenophorum contained 0.372% of total nitrogen, 0.062% of total phosphorus, 0.580% of total potassium, 0.478% of calcium, 0.059% of magnesium, 0.017% of iron, 0.069% of sulfur, 0.279% of silicon, 2.459 mg/kg of copper, and zinc. 10.139 rog/kg, manganese 29.527 mg/kg, boron 5.259 mg/kg, molybdenum 0.204 mg/kg. (B) Strong reproductive capacity, high stem and leaf yield Eupatorium can produce a large number of seeds, sexual reproduction through the spread of wind, humans, animals, and vehicles, and asexual reproduction through the generation of roots and stems. Rapid expansion in a short period of time, forming a contiguous piece. After Eupatorium adenophorum enters vigorous growth, its branching amount and growth amount are relatively large, and a large number of young stems and leaves can be produced for production and utilization. According to the survey, 10855.5 kg of fresh leaves and stems can be produced per hm2. (3) Wide distribution range, easy to use Eupatorium adenophorum is distributed in most counties of Yunnan Province, and it grows from 165m to 2915m above sea level. It can adapt to hot and humid climates, but it can also grow in cool regions. Behind the houses, there are Eupatorium adenophorum on the barren hills around cultivated land, which provides convenience for collection and utilization. Second, the use of ways (A) cut green for green manure Eupatorium in the vegetative growth period, the collection of young stems, leaves, chopped into 10-15cm with a sickle, sprinkled in the field, after plowing into the soil as a base fertilizer Application. (2) Cutting green for composting materials During the vegetative growth period of Eupatorium adenophorum, young shoots and leaves are collected and chopped with a guillotine to form 10-15 cm, and a small amount of worm manure is added for fermentation. One month later, it was taken out as base fertilizer. (3) Cutting green for anaerobic growth period of Eupatorium adenophorum in raw material of biogas fertilizer, collecting young stems and leaves, chopping into 20-30cm with a guillotine knife, and putting it into a biogas digester, adding human and animal waste and urine Fermentation. When the tank manure is removed, it is used as base fertilizer. (D) cut green for ground cover collection of young Eupatorium adenophorum stems, leaves, with a guillotine and cut into pieces of 20-30cm covered in the surface of planted crops, both water and fertilizer can be. (five) cut green used as a gasket to collect young stems, leaves, chopped with a guillotine or directly into the circle, the accumulation of both manure for production use. However, care should be taken to cause asthma and hooves in horses and cattle. (6) Feeding livestock feed to abdomen and returning livestock can eat the Eupatorium adenophorum feed that has been detoxified, and produce manure to be used as fertilizer. At present, Yunnan Institute of Microbiology has developed a process for detoxification of E. adenophorum as feed. (7) The use of grass-burning ash as fertilizer In the winter and spring seasons, combined with the clean slopes and barren slopes around the arable land, the dried Eupatorium odoratum is dried and mixed with the humus soil to produce “fire and earth ash”.

Our medicinal synthetic polyisoprene gasket for injection does not contain any substances that can easily produce pyrogen. We now use a unique technique to add cytotoxicity to the routine test of butyl rubber stoppers such as pyrogen, hemolysis, acute systemic toxicity test and so on. Systemic injection test and intradermal stimulation test have been used abroad for many years.Our good puncture resistance ensures the minimum rate of chip drop during the puncture process and our good self-sealing performance can guarantee no leakage during using process in hospital.Also,good retention of puncture device ensures that there is no needle slider and needle drop in the process of hospital use.
