Abstract
The invention discloses a method for promoting natural regeneration and direct seeding forestation of a non-dormant white oak forest and belongs to the technical fields of vegetation recovery and forestation. According to the key point of the technical scheme of the invention, the method for promoting natural regeneration and direct seeding forestation of the non-dormant white oak forest particularly comprises the steps of adopting seed net covering protection on non-dormant white oak acorns in a seed rain peak period; and adopting seed net covering protection on direct seeding forestation of non-dormant white oak tree seeds after the seeds are sowed. The method is wide in application range; in particular for a region which bears high animal predation pressure and tree seeds with low survival rate caused by a tree planting forestation method, a direct seeding forestation seed net covering technology can be adopted, and a good effect is achieved.
Description
Technical field
The invention belongs to revegetation and afforestation technology field, and in particular to one kind promotes non-sleep leucobalanus group forest day
Right renewal and the method for direct seeding forestation.
Background technology
Forest has the title of the lung of the earth as the main body of terrestrial ecosystems, in the history of human survival and development
Play irreplaceable effect.However, current extensive forest degeneration, fragmentation.Therefore, how to recover and protect or just
The focus of international concern is become in the forest ecosystem degenerated.The natural regeneration of forest is the one of woody plant community, xylium's development
Individual important step；Direct seeding forestation technology is due to more economical compared with planting by stock technology, easy to operate, time saving and energy saving and become human intervention
The lower important measures accelerated Forest restoration and update, but how to improve the speed and seed sowing efficiency of forest natural regeneration
Always subject matter present in Silviculture.
Many biological and abiotic factors can affect the speed and seed sowing efficiency of forest natural regeneration, wherein mouse
The destructive predation of class and other animals to seed is extremely serious to forest natural regeneration and the impact of seed sowing, or even can lead
Cause sowing failure.Conventional research has made many beneficial with regard to how to protect the seed dropped during Seed Rain and live seed aspect
Trial, but these research emphasizes to use highly toxic pesticide（Such as zinc phosphide, six or six powder, Antorane）Poisoning muroid etc. animal or
Using repellant（Such as thiram, capsicim）Etc. reducing the predation of muroid, but these infectious agents using can serious harm
Wild animal and the safety of the mankind, or even cause ecocatastrophe.Therefore, explore some safely and effectively approach ensureing forest day
So update and direct seeding forestation is successfully very necessary.

Further preferably, at least 3, described support iron wire post.
Further preferably, described non-sleep leucobalanus group acorn nut adopts the tool of seed enclosure protection in Seed Rain peak period
Body process is：Seed Rain peak period, the intact seed of the regional choice beyond elite stand tree crown coverage, to seed 2- is covered with
3cm thick fine earth, assembling seed covers net, seed is covered to seed to cover and nets interior, and seed is covered into net and fixed, by seed after January
Cover net to remove.
Further preferably, the direct seeding forestation of described non-sleep leucobalanus group acorn nut after planting covers net in seed using seed
The detailed process of protection is：The line space for controlling each protection point is 1-1.5m*2m, in each protection bunch plating 3-5 grain seed,
And the thick fine earths of 2-3cm are covered with, assembling seed covers net, seed is covered to seed and is covered in net, and seed is covered into net and be fixed on guarantor
Shield point, covers net and removes after one month by seed.
The present invention has the advantages that compared with prior art：
1st, present invention design does not affect all ecological factors needed for seed growth while protecting seed to avoid being taken predation；
2nd, the technology of the present invention is simple, easy to operate, with low cost, can effectively improve Seed viability, is to promote seed to sprout, day
Right renewal and the new way of scondary forest revegetation；
3rd, the present invention is applied widely, is especially subject to the area of larger animal predation pressure and is survived using planting by stock method
The low seeds of rate, can cover network technology using direct seeding forestation seed, and can obtain preferable effect.

Embodiment 1
Non-sleep leucobalanus group acorn nut adopts seed enclosure protection in Seed Rain peak period
Seed Rain peak period, the intact seed of the regional choice beyond elite stand tree crown coverage, is covered with 2-3cm's to seed
Fine earth, assembling seed covers net, seed is covered to seed and is covered in net, and seed is covered into net fixation, and seed is covered into net after January
Remove.2cm earthing（Simulation animal Scatter hoarding）With earthing+down seed release station acuteserrata and cork oak seed are deposited to cover net process
Dynamic is stayed as shown in Fig. 24 days after seed release, seed release station is not covered all acorn nuts of net all by rodent predation or expanded
Dissipate.Although earthing process can slightly slow down animal to Acron predation, notable sparing action is not played.Cox regression analyses show, little
Type rodent to being scattered and earthing processes the selection of lower two kinds of seeds and significant difference is not presented naturally（Acuteserrata：Wald=
0.000,df=1,P=1.000；Cork oak：Wald=0.000,df=1,P=0.995）.By contrast, earthing+cover net is processed to two
Plant seed and play protective effect（Acuteserrata：Wald=6.093,df=2,P=0.048；Cork oak：Wald=7.145,df=2,P=0.028）.Cut-off last time is investigated, and is covered net and is processed acorn nut to have part to occur rotten to the corn, but is not caught by rodent or birds
Food, the acorn nut more than 55% is sprouted.
Embodiment 2
The direct seeding forestation of non-sleep leucobalanus group seeds after planting adopts seed enclosure protection in seed
The line space for controlling each protection point is 1-1.5m*2m, and in each protection bunch plating 3-5 grain seed, and it is thick to be covered with 2-3cm
Fine earth, assembling seed covers net, seed is covered to seed and is covered in net, and seed is covered into net is fixed on protection point, after one month
Seed is covered into net to remove.2014 and 2015 continuous 2 years fields sowing tests find, cover net and process 100 sampling point acorn nuts except part
（Respectively 11% and 19%）Generation is rotten to the corn outer, and not by rodent or birds predation, germination rate is significantly higher than control（PIt is little
In 0.001）.
General principle, principal character and the advantage of the present invention is embodiment above describes, the technical staff of the industry should
Understand, the present invention is not restricted to the described embodiments, the original for simply illustrating the present invention described in above-described embodiment and specification
Reason, under the scope without departing from the principle of the invention, the present invention also has various changes and modifications, and these changes and improvements each fall within
In the scope of protection of the invention.
