Description
Technical field
The invention belongs to forestry planting technology fields, are related to a kind of stony desertification with lasting improvement stony desertification soil
The method of ecological region planting locust tree.
Background technique
Stony desertification, also known as land desertification, refer to causes surface soil to lose because of soil erosion, exposed bedrock, soil funeral
The phenomenon that losing agricultural use value and environmental degradation.Stony desertification mostly occurs in In Limestone Area, and soil thickness is thin, and (majority is not
Sufficient 10cm), natural vegetation is constantly destroyed, and earth's surface is exposed, soil erosion, Land capability decline or forfeiture.Stony desertification
Mountain torrents, landslide, mud-rock flow easily occur for area, in addition underground karst is developed, bloods and droughts are caused frequently to occur, almost year after year non-irrigated
Flood is together；Meanwhile the exposed rate of Karst Mountains Desertification Area rock is high, soil is few, and water storage capacity is low, and rock stratum water-leaking property is strong, easily causes to lack
Water arid, and heavy rain will lead to serious erosion of soil and water.By 2011, stony desertification land area in China's was 1200.2 ten thousand public
Hectare, the 11.2% of monitoring section national territorial area is accounted for, Rocky Desertification Control and restoration of the ecosystem task are very arduous, still need to long-term effort.
Locust tree also known as acacia, pulse family robinia deciduous tree are a kind of important quick growing species of trees.Its root system is shallow and flourishing,
Have root nodule, can be increase soil fertility with fixed nitrogen.Locust tree is adaptable, compared with saline-alkali tolerant, barren and arid soil, barren
In soil, it compared with normal growth, can also be not only commerical tree species, the energy tree species, nectariferous plant, even more one of great economic value
The ecological tree species that kind can persistently improve soil for a long time, conserve water and soil.
Summary of the invention
The present invention provides a kind of methods of stony desertification ecological region planting locust tree, plant locust tree using big specification nutrition cup,
This method locust tree high survival rate, it is easy to operate, and have effects that persistently to improve stony desertification soil.
A kind of method of stony desertification ecological region planting locust tree, comprising the following steps:
Step 1 prepares nursery, interim seedling growth greenhouse is built near planting site, carries out nutrition cup nursery, institute using Robinia pseudoacacia Seeds
Stating nutrition cup is degradable non-woven fabrics nutrition cup, and diameter of section 20~30cm, high 20~30cm fill nutrition in nutrition cup
Matrix；
Step 2, seed seedling-raising
(1) it sows, each nutrition cup broadcasts 2-5 seed, and at 2~3cm of depth distance rim of a cup, after planting earthing, is gently suppressed, and is filled out
Full seedling-raising cup, sprinkles profoundly water；
(2) control is moistened, day temperature is controlled at 20~33 DEG C, and night temperatures are at 15 DEG C or more；Water content of substrate is controlled 40
~60%；
(3) water and fertilizer management when emergence 80%, sprays 2~5g/L urea, be spaced 10~15 days it is primary；
(4) disease control after planting alternately sprayed Mancozeb or thiophanate methyl or hymexazol medicament every 10~15 days, in advance
The generation of anti-fungal venereal disease evil；
(5) hardening opens all ventilation openings, leaks informaton, gradually reduce irrigation amount, the case where not wilting 7~10 days before transplanting
Under reduce watering to the greatest extent, until seedling can adaptation external environment gradually；
Step 3, digs planting pit, and seeding row spacing is 1.5m × 1.0m；It is excavated on ground by locust tree seeding row spacing using Portable Digging Machine
Planting pit forms planting point arranged vertically and horizontally；Drainage system is set, avoids low-lying ponding, locust tree root system is prevented to be chronically at flood
Wet environment；
Step 4, field planting selects disease-free, healthy and strong, plant height 20--50cm seedling generally in spring to early summer, in company with nutrition
Cup embedment planting pit；
Step 5, water and fertilizer management, plantation First Year need to water, and keep seedling growing area soil humidity 40% -60%；Fertilising 2 in 1 year
~3 times, with the growth of growth year, dose is gradually increased；First Year, the first tenday period of a month in April application ternary compound fertilizer (N:P:K=
15:15:15) 0.3~0.5Kg/ plants, cave is applied, and is watered in time；Ternary compound fertilizer late July (N:P:K=15:15:15) 0.3~
0.5Kg/ plants, cave is applied, and is watered in time；
Step 6 vacuates, and after field planting, 2 meters of locust tree height or more, canopy density are up to 0.6, and interlacing vacuates at this time, tunes up locust tree
Seeding row spacing is to 3.0m × 2.0m；It after several years, when Locusts being waited to need to vacuate again, interlacing can vacuate again, tune up locust tree strain
Line-spacing meets major diameter wood culture enough and is used to 3.0m × 4.0m；And the Seedlings of Black Locust removed can be used as afforestation later period benefit
The wood that plants seedlings is used, or is sold as engineering seedling, additional income.
As optimization of the invention, in step 1, the nutrient matrix is made of the raw material of following important part: organic fertilizer
1200~1500 parts, 100~120 parts of calcium magnesium phosphate, 20~30 parts of sawdust, 3~5 parts of 5% phoxim baythion granule；
As optimization of the invention, in step 2, seed carries out presoaking and germinating prior to seeding；2~3 days before carrying out presprouting of seeds
Selection fine day is basked seeds, and is then weeded out the seed of empty, flat, sick wound, damage, is left full, substantial high quality seed；Seed is put
After impregnating 10~15 min clocks in 50~55 DEG C of warm water, pull that be placed on 60~80 mg/L gibberellin, 500~800 mg/L more out
It is impregnated again in bacterium spirit compositional liquor 2~3 days；It is put into germinating box after digging out, exists in air themperature in 28~30 DEG C, relative air humidity
90% or more isoperibol vernalization, suitably keeps the skin wet, and just can be used to sow when seed germination rate reaches 60~70%；
As optimization of the invention, in step 2, in seedling raising process, spray 2~4 times No. GGR6, promote seedling root growth,
Cultivate the strong sprout of well developed root system；
As optimization of the invention, in step 3, locust tree planting pit size can be fully embedded nutrition cup less times greater than nutrition cup；
As optimization of the invention, in step 4, with 3000~5000 times of bacterium solution pouring roots of microbial bacterial agent, institute in three days after afforestation
Microbial bacterial agent is stated to be compounded by probiotics such as composite bacillus, Trichoderma harzianum, rhizobium, living bacteria count 100,000,000,000/
g。
Mainly have the advantage that including the following:
1. method of the invention is easy to operate, locust tree high survival rate, and has effects that persistently to improve stony desertification soil；
2. using seed seedling-raising, i.e. seedling compares grafting, cuttage seeding, have grow vigorous, well developed root system, the service life compared with
Long feature is more suitable for improveing soil for a long time, repairs ecology and be used；
3. kind of plant locust tree improvement soil is a kind of process lasting for a long time, it is more lasting to repair ecological effect；
4. being able to suppress germ reproduction in soil and invading to plant root, effectively mitigation pest and disease damage, chesson, activation are improved
Soil enhances plant metabolism, and rhizobium also can increase the nodule nitrogen fixation ability of leguminous plant locust tree；
5. big specification nutrition cup is directly embedded to planting pit when field planting, it is fixed to complete under the premise of not changing seedling growth environment
It plants, avoids damage root system, also eliminate adaptation of the nursery stock to soil, eliminate seedling-slowing stage, substantially increase transplanting survival rate.
