Abstract
A kind of pine tree forest culture and management tree species nursery and planting technology, belong to tree species seedling-raising technique field, including seed impurity removing broken skin, site preparation, nursery soil disinfection, item of ditching, presprouting of seeds, sowing and etc..Using the method for tree species nursery of the invention, the survival rate of pine tree can achieve 85% or more.Percentage of seedgermination by broken skin is higher than the percentage of seedgermination with intact seed coats, this is primarily due to the kind skin of seed with cuticula, hinders embryo to absorb moisture and oxygen, forms the reason of kind of skin obstacle.The present invention stirs kind using 60-70 DEG C of warm water, then for 24 hours with 30 DEG C of water seed soakings, to achieve the purpose that improve the germination percentage of seed.The present invention plays certain facilitation to germination using bark matrix, and emergence rate can be improved.Seed disinfection and soil disinfection can pre- preventing disease and pests.Seedling planting density is the growth that 25cm × 6cm is more advantageous to seedling.
Description
Technical field
The invention belongs to tree species seedling-raising technique fields, and in particular to a kind of pine tree forest culture and management tree species nursery and planting technology.
Background technique
The growth of pine tree not will receive the limitation of edaphic condition and weather, can grow up strong and sturdy under any environment, have pole
Strong fertility, therefore pine tree is a kind of tree species distributed more widely, is usually used in urban afforestation and closes hillsides to facilitate afforestation, and has higher
The ecological value, social value and economic value.In recent years, China increases environment protection, and the engineerings such as close hillsides to facilitate afforestation are more next
More, pine tree nursery stock amount to be used is also increasing, this requires carrying out scientific nursery, correct plantation to pine tree, to ensure
The quality and survival rate of pine tree nursery stock, and further promote the development of related industry.
Summary of the invention
According to problems of the prior art, the present invention provides a kind of pine tree forest culture and management tree species nursery and planting technology, with
Improve the quality and survival rate of pine tree nursery stock.
The present invention uses following technical scheme：
A kind of pine tree forest culture and management tree species nursery and planting technology, include the following steps：

Step 2：One piece of smooth and not pest and disease damage plot is selected in nursery lot, is carried out site preparation and is obtained seedbed, in site preparation
In the process, processing of digging should be carried out, bulk soil block is thoroughly smashed, clears up barren rock therein, weeds, prior to seeding 30d, then into
1 depth of row is digged, and ploughing depth will reach 20-25cm；
Step 3：Nursery soil disinfection, every square metre is spread on earth's surface with 1.5 grams of carbendazim and ploughs under in soil；
Step 4：Seedbed is harrowed after thin leveling and do furrow, the long 8m of furrow, the wide 1.2m of furrow open seed furrow along seedbed in furrow,
Ditch depth 4cm, furrow width 8cm, two bar ditch spacing are 25cm, and every furrow open four seed furrows, apply fertilizer after digging, first pour and apply in ditch
Dung polluted water water-wet profit makees base manure, and seedbed is watered to 1-2 times daily to ensure humidity in seedbed before sowing；
Step 5：Seed is cleaned with clear water, seed is put into container, is subsequently added into 60-70 DEG C of warm water, and be sufficiently stirred
Seed is not stirred for seed when water temperature is gradually cooled to 30 DEG C, continues seed soaking and pulls out afterwards for 24 hours, then with 0.5% Gao Meng of mass concentration
Sour aqueous solutions of potassium soaking disinfection, bath raio 500:1, time 3h are cleaned 2-3 times after disinfection with clear water, are admixed after draining away the water
Wet sand, by seed and wet sand weight ratio 1:The stirring of 3 ratios is placed in place leeward, on the sunny side, 20 DEG C of temperature is kept, with leaching
The straw screen or mat covering for crossing water, keeps water content 55%-60%, vernalization 3-4d, seed is sprayed per daily 30 DEG C of warm water, while being turned over
It is dynamic, it keeps seed dry and wet uniform, sees that seed is split after mouth shows money or valuables one carries unintentionally, can be sowed；
Step 6：Seedbed is irrigated before sowing, seed is sprinkled into ditch treated, 1 seed per cm, and fire is covered after broadcasting
Native ash, fine earth, bark, primary watering in 3 days, 10d spray primary Ban Liang formula Bordeaux solution, and come up laggard seedling in the ranks, and one
A phosphate fertilizer is applied week on seedling, until sprout lateral root and tender leaf appearance；
Step 7：After sowing 100 days, when height of seedling 15-20cm, ground diameter 0.2-0.3cm, can be out of the garden afforestation.
Preferably, physical purity of seed is 93%-95% in the step one, the cleanliness %=pure seed weight/(pure
Net seed weight+other plant seed weight+field trash weight) × 100%.
Preferably, the germination percentage of seed is 23-26% in the step five, the total grain of germination percentage %=germination
Total grain number × 100% of number/test.
Preferably, bark is then to crush bark raw material through compost 1 year or more in the step six, crosses 40 mesh
Sieve.
Preferably, concentration of applying fertilizer in the step four is 0.015kg/L.
Preferably, in the step six 1-4 plants of seedling spacing in the rows of every bar ditch be 5cm, the 5th plant with the 4th plant of interval 55cm,
The seeding row spacing of 5-8 plants of seedling is 10cm.
Preferably, seedling planting density is 25cm × 6cm in the step six.
The beneficial effects of the present invention are：
1) using the method for tree species nursery of the invention, the survival rate of pine tree can achieve 85% or more.
2) percentage of seedgermination Jing Guo broken skin is higher than the percentage of seedgermination with intact seed coats, this is primarily due to seed
Kind skin has cuticula, and embryo is hindered to absorb moisture and oxygen, forms the reason of kind skin obstacle.
3) present invention stirs kind using 60-70 DEG C of warm water, then for 24 hours with 30 DEG C of water seed soakings, to reach the germination for improving seed
The purpose of rate.
4) certain facilitation is played to germination using bark matrix, emergence rate can be improved.
