Description
Technical field:
The present invention relates to afforestation fields, are specifically related to a kind of naked, black pine impregnated based on negative pressure technique and liquid
Sapling method of forestation.
Background technique:
Ecological environment is the primary condition of human survival and development, is the basis of economy and society development.Protection and improvement
Ecological environment realizes sustainable development, is the basic principle that must be adhered in China's modernization construction.But currently, I
The ecological environment of state is still more fragile, and the deserted mountain area as caused by soil erosion is not also contained effectively.Therefore,
It afforests deserted mountain extremely urgent so as to improve ecological environment.Compared with common afforestation, afforestation can face more
Difficulty, mainly due to the problems such as deserted mountain lies waste for a long time, water bar part is poor, and soil fertility is insufficient, hardened serious.Therefore, how
Adaptation to local conditions selects suitable afforestation technology, obtains good afforestation effect, is the important key improved the ecological environment.
At present there is main problems faced in afforestation: larger, more severe for the environment mountainous region of afforestation difficulty, revegetation
Difficulty is larger；Cost of forestation is larger, and kind shoot survival percent is lower during afforestation, and Fertilizer application is more, and Mountain Conditions difference etc. increases
The cost of afforestation is added；It finances more difficult, for afforestation mainly based on ecological benefits, but due to afforestation
It is at high cost, the period is long, economic benefit is poor, causes capital investment enthusiasm not high；Science and technology relatively lags behind, the mould of afforestation
Formula is simpler, constrains the raising of the efficiency and quality of afforestation significantly.
Black pine, and be white gomphiasis, bark band grey black.Light, drought-resistant barren, intolerant to waterlogging, resistant to diseases and insects is strong,
Growth is slow, and the service life is long.It is green barren hill, road avenue afforestation first choice tree species that black pine is green for a long time throughout the year.Plantation for black pine
Specifically include that site preparation, transplanting, management and maintenance, the prevention and control of plant diseases, pest control.Although black pine impoverishment tolerant ability is stronger, due to
Deserted mountain rugged environment considerably increases so that the survival rate of black pine sapling is not high, and pest and disease damage is more serious in growth course
The cost of afforestation.
Patent (CN201511035396.4, the applying date: 2015.12.30) discloses a kind of water-saving irrigation raising bare-root seeding
The method for planting of the surrival rate of afforestation, specifically includes the following steps: Step 1: Tree Species Selection: selection tree species: black pine, arbor-vitae, elm
Tree, locust tree, smoke tree, Chinese wax are any；Step 2: digging planting hole: determining plant according to reproducing area type and nursery stock specification
Cave shape and specification, plains region are generally truncated cone-shaped, and non-varieties in saline-alkali areas specification is appropriate big, upper diameter 60cm-
80cm, below diameter be 40cm-60cm, depth 60cm-80cm；Plain varieties in saline-alkali areas specification: upper diameter 50cm-60cm, under
Face diameter 40cm-50cm, depth 50cm-60cm；The present invention guarantees that limited moisture concentrates on around seedling root, and
Be not easy to evaporate it is lost, help to solve Survival rate of nursery stock it is crucial during root tissue water status supply, while reducing weeds to soil moisture
With the competition of nutrient, for seedling root survive and growth provides ideal subenvironment, guarantee the surrival rate of afforestation, solve to lack
The problem that water area afforestation irrigation cost is high, the surrival rate of afforestation is low.Although this method can improve naked sapling to a certain extent
Survival rate, but the survival rate of sapling is still very low, needs to further increase.
Patent (CN201610499358.2, the applying date: 2016.06.30) disclose it is a kind of using high potassium bitter with it is light
The root-divided alternative irrigation method of water and its salt-soda soil plantation black pine application, specifically: including being laid with every salt deposit, root being divided to hand over
For irrigation；It is described every salt deposit be laid with step interval salt deposit include: rubble layer, Wheat Straw layer, microlith layer, soil layer.Rubble layer packet
It includes: boiler ash sediment, vermiculite, stone；Microlith layer includes: fermentation sawdust, desulfuration waste；Soil layer includes: fertile soil, Chi Yutu.This
Invention also provide it is a kind of using the root-divided alternative irrigation method of high potassium bitter and fresh water salt-soda soil plantation black pine application.
Using root-divided alternative irrigation method of the invention, root system of plant adaptability is also greatly enhanced, in the lower soil of water content
It grows fine, while plant root system development is good, the speed of growth is fast；Fresh water dosage substantially reduces, and fresh water dosage is more commonly irrigated
Fresh water dosage reduces 50%-60%；The water use efficiency of irrigation water is promoted to 90% or more simultaneously；Greatly reduce plant not
Necessary transpiration.Although this method can effectively improve black pine in salt-soda soil to the utilization rate of water, in afforestation
When black pine survival rate still cannot be effectively improved.
Summary of the invention:
The technical problem to be solved by the present invention is to when afforestation in the prior art, naked sapling survival rate of black pine is lower,
Pest and disease damage is serious in growth course, and cost of forestation is high.In order to solve the above technical problems, the present invention provides one kind to be based on negative pressure
Naked sapling method of forestation of black pine that technology and liquid impregnate, this method is in naked sapling transplanting of black pine under condition of negative pressure
Epiphragma processing is carried out to cave face using nutrient solution immersion treatment, and after transplanting, and effectively prevents disease in sapling late growth
Insect pest, so that the survival rate of black pine sapling greatly improves.
In order to preferably solve above-mentioned technical problem, The technical solution adopted by the invention is as follows:
A kind of naked sapling method of forestation of black pine impregnated based on negative pressure technique and liquid, comprising the following steps:
