Description

A kind of beech seeds planting management method

Technical field

The present invention relates to a kind of beech seeds planting management method

Background technology

Beech trees is a kind of large-scale arbor, characteristic such as have happiness light, material is good, the life-span is long, disease and insect resistance, wind resistance, anti-cigarette ability are strong, and tree-like grace, and ornamental value is very high.The beech tree is often adopted the seedlings plantation, and the planting technology requirement is high, difficulty is big, and survival rate and growth rate after carelessness just can influence the sapling plantation are arranged slightly, causes the sapling wasting of resources and brings very big economic loss.

Summary of the invention

Goal of the invention: the object of the present invention is to provide a kind of beech seeds planting management method, improve the survival rate and the growth rate of beech tree cultivation.

Technical scheme: to achieve these goals, a kind of beech seeds planting management method of the present invention comprises the steps:

1) excavated diameter is than the big 20cm of native ball, the transplanting cave of the high 20-30cm of depth ratio soil ball height, and sapling is transplanted to the cave, the filling chesson, compacting, transplanting depth is that native ball top layer flushes with the face of land and is advisable; Cultivation seeding row spacing 3 m * 4m; The new not basal dressing of sapling of transplanting waters permeable; To carry out strut to big sapling, prevent limb waving;

2) newly transplant sapling, watered once in about 7 days, guarantee that the blade face is moistening, after waiting to come into leaves, Ye Weijuan promptly waters.Want timely draining rainy season, prevents that root system is immersed in the water for a long time;

3) spread fertilizer over the fields urea or two ammonium 10-15kg/ mus after the germination; Treat the relieving of sapling young leaves, get into the long thick leaf phase, spread fertilizer over the fields composite fertilizer 10-15kg/ mu; Later stage was whenever spread fertilizer over the fields composite fertilizer once at a distance from 2 months; And at sapling both sides trench diggings winter dressing, promptly in twelfth month at trench digging from trunk 50cm place, the size of ditching is: wide 45-50cm, 50cm deeply, 2kg/ of organic fertilizer in ditch (chicken manure of fermentation, pig manure etc.), composite fertilizer 0.25kg/, 0.25kg/ of carbon ammonium;

4) adopt weeding by machine's mode to carry out weeding.According to the pests occurrence rule of sapling main diseases insect pest, in time prevent and treat.

Beneficial effect: a kind of beech seeds planting management method of the present invention has improved the adaptive capacity of cultivation back beech tree through each item link; Landscape effect is good; Survival rate reaches more than 95%; With 1m place trunk diameter overhead is index, finds that the beech tree of the about 2cm of trunk diameter passes through the method cultivation management, and 3 years trunk diameters of field planting can reach 10cm.

Embodiment

1) plantation

Before and after the beginning of spring, select trunk 2cm sapling, excavated diameter is than the big 20cm of native ball, the transplanting cave of the about 50cm of the degree of depth, sapling is transplanted to the cave, the filling chesson, compacting, transplanting depth is that native ball top layer flushes with the face of land and is advisable, and waters permeable.The tree seeding row spacing is 3 m * 4m.

2) irrigation and draining

New transplanting sapling was watered once in about 7 days, guaranteed that the blade face is moistening, and after waiting to come into leaves, Ye Weijuan promptly waters.Want timely draining rainy season, be prone to the ponding place, dig trenches to drain the water away, prevent that root system is immersed in the water for a long time at hypsography low-lying.

3) fertilising

Spread fertilizer over the fields urea or two ammonium 10-15kg/ mus after the germination; Treat the relieving of sapling young leaves, get into the long thick leaf phase, spread fertilizer over the fields composite fertilizer 10-15kg/ mu; Later stage was whenever spread fertilizer over the fields composite fertilizer once at a distance from 2 months.

4) winter dressing

Twelfth month,, at the trench digging from trunk 50cm place, the trench digging size is: wide 45-50cm, dark 50cm, 2kg/ of organic fertilizer in ditch (chicken manure of fermentation, pig manure etc.), composite fertilizer 0.25kg/, 0.25kg/ of carbon ammonium.

5) weeding and the extermination of disease and insect pest

Adopt weeding by machine's mode to carry out weeding.According to the pests occurrence rule of sapling main diseases insect pest, in time prevent and treat.
