Abstract
The invention relates to a method for building drought mountain sabina przewalskii, which comprises the following steps of: ploughing soil by advancing a growing season during afforestation, ploughing the soil by a horizontal ditch, a horizontal step or a counter-slope bench terrace at a gentle slope and carrying out shrub afforestation when the soil is thawed in the spring of the next year; arranging planting points in a shape like the Chinese character pin; afforesting when the soil is thawed by 30-40cm in the early spring, soaking a seedling root by slurry prepared from diammonium phosphate and a water-retaining agent before afforestation and selecting first-class and second-class seedlings which grow in 3 to 4 years and have the seedling height of more than 20cm, healthy and strong development and good root system to afforest; in order to advance the crown closure of a sabina przewalskii forest, carrying out hybridizing configuration on shrub species according to the counter-slope bench terrace or the horizontal ditch and configuring caragana and barberry of the shrub species at the sunny slope; and configuring of caragana microphylla, hippophae rhamnoides and dasiphora davurica the tree species at the semi-sunny slope. By changing the traditional afforestation method adopting the cheap, simple and easy method, the afforestation survival rate of the drought mountain sabina przewalskii is improved, the sustainable construction of the modern forestry is accelerated, forest resources are effectively expanded and the ecological environment is improved.
Description
Technical field
The present invention relates to drought mountain afforestation complex art, particularly a kind of expansion forest resources are improved the ecological environment, and the integrated technology system of developing ecology forestry is specifically
Background technology
It is imperative to improve the ecological environment by afforestation at drought mountain, but the complex art of present drought mountain afforestation seems and relatively lags behind, bury seedling afforestation method, pitting all belong to traditional method of forestation by technical measures such as wall planting methods distortion as soil moved in to improve the original afforestation method, the ridging that can find at present, use above-mentioned technology and plant Qilian Chinese juniper survival rate only about 50% at drought mountain, greatly having restricted the improvement process and the afforestation effect of ecotope, also is restriction forestry sustainable development, the outstanding problem many, that afforestation effect is little, ecological recovery is difficult of spending.It also is the practical problem that is not resolved for a long time.At the construction of the drought mountain Qilian Chinese juniper of spending, except that the technological invention applicant, do not appear in the newspapers as yet at present in the gradient 20～30.
Summary of the invention
The object of the invention is to improve drought mountain Qilian Chinese juniper survival rate with spending less and simple and easy to do method, accelerates the sustainable construction of Modern Forestry, effectively enlarges the forest resources, improves the ecological environment.
The objective of the invention is to be achieved through the following technical solutions:
A kind of method for building drought mountain sabina przewalskii is characterized in that comprising following method and step:
A, entire technique
Whole ground season and method: carry whole ground of the previous season of growth during afforestation, adopt the whole ground of horizontal ditch, horizontal rank or reversed terrace on the gentle slope, the reversed terrace specification is 0.8 * 2 * 0.4m, and soil thawed and carried out shrub afforestation spring in next year; Plant plant hole and press reversed terrace or horizontal ditch layout, the afforestation seeding row spacing is according to gradient size, and the horizontal ranges between the two row ditch hearts are selected 2～3m for use up and down;
The arrangement of B, runoff gathering and plantation point
Taking runoff catchment method, the catchment area in each tree planting cave during whole ground is 3～6m
2, plantation point " product " font is arranged;
C, afforestation time and method
Afforest when soil thaws 30～40cm in early spring, shoot root band Tu Tuo, the size that sticks together soil does not expose with most shoot roots and is as the criterion, shoot root dips in the mud that is mixed with diammonium phosphate, water-loss reducer before the afforestation, its slurry is thick is advisable with energy " messenger wire ", select for use 3～4 years living more than the height of seedling 20cm, grow healthy and strong, the I and II seedling afforestation that root system is intact;
D, planting density and configuration shrub
Be the closing of Qilian Chinese juniper woods ahead of time, mix the configuration of handing over shrub species and press reversed terrace or horizontal ditch layout that the afforestation seeding row spacing is selected the seeding row spacing horizontal range 2 * 1m between the two row ditch hearts up and down for use, spacing in the rows 50cm according to gradient size; Tailo configuration shrub species caragana and barberry; Half light slope adapted caragana microphylla, sea-buckthorn and Yin Lu Japanese apricot kind;
The described small dimension reversed terrace that adopts: long 50～70cm, wide 30～40cm, dark 40cm, horizontal ditch 0.5 * 2.5 * 0.4m wholely.
The described mud that is used to dip in root is formulated in 10: 0.5: 1 ratio successively by soil, diammonium phosphate and water-loss reducer.
The method of drought mountain of the present invention Qilian Chinese juniper afforestation technology at first is that afforest next year with elder generation year whole ground.Plant plant hole and press reversed terrace or horizontal ditch layout; Next is in the way of taking runoff to catchment, and plantation point " product " font is arranged; The 3rd, shoot root dips in the mud that is mixed with materials such as diammonium phosphate, water-loss reducers and dips in root before the afforestation; The 4th, afforestation cave covering with plastic film.Use this technology, now built large-area Qilian Chinese juniper woods, obtained remarkable economic efficiency and ecological benefits at Qilian mountains drought mountain.With spending less and simple and easy to do method, improved drought mountain Qilian Chinese juniper survival rate, accelerated the sustainable construction of Modern Forestry, effectively enlarged the forest resources, improved ecotope.
