Taxus Mairei Development Use Essential Camp Afforestation Engineering Research

Taxus mairei is the cretaceous period survivors tree seed, in1999is included the national level protection plant.South the Chinese yew collection timber wood, the medicine, the ornamental value in a body, is by no means the thing by thin and expensive expensive, but has the very high development value.South in recent years developed the Chinese yew production base and so on each kind of company to establish in abundance, south the development the Chinese yew industry tendency was violent, but each place has not formed the system to the south Chinese yew habit of growth research and the camp afforestation technology the technical guidance model for painting.This discusses bases on the Lishui city lotus all area each south Chinese yew production base, has carried on the summary to the for many years south Chinese yew cultural technique experience, but has obtained south the Chinese yew "the childhood happy cloudy3years later in the illumination sufficient place growth better; But life-long happy wet fears the ponding; But happy fat the root system cannot and the fertilizer direct contact" biology characteristic.Revolves its biology characteristic, designs and carries out each kind of cultivation and the management measure, cultivates the base in the seedling cultivation and each kind of management goal planted forest to carry on the experiment, through the reality compared to, analyzes each kind of difference reason, chooses the best technical plan, will take the next south Chinese yew base production and the management theory instruction.The endeavour south introduced completely the Chinese yew production process and the system cultivation technology, provides the technical model now for the producer.This research preferred plan, south the manual cultivation the Chinese yew can achieve that,1year lives seedling most greatly highly25cm, most earth diameter0.44cm;2years live seedling most greatly highly98cm, most earth diameter1.90cm;3years live seedling most greatly highly195cm, most earth diameter3.80cm;4years live seedling most greatly highly270cm, most earth diameter6.10cm;5years live seedling most greatly highly333cm, most earth diameter7.83cm.South the Chinese yew planted forest, after cultivates for20years to be possible to achieve the craft is mature, Chinese acre material quantity3-5m3, the yield per mu lumber income theoretically may amount to6-150,000Yuan; South the Chinese yew for medicinal purposes forest, the yield per mu value may amount to25695-31405Yuan; A Chinese acre south Chinese yew seedling, passes through6years cultivation, can have155300Yuan income.
