Problems solved by technology

During the planting of seedlings, it is often encountered that geological soil compaction, poor water permeability or impermeability make the root system of seedlings unable to take root or the planting period of seedlings is too late, the planting period has passed, drought, less rain, low temperature, low air humidity, and seedlings are easy to appear The tree trunk loses water, the ground surface is cracked, and the roots are frozen, which leads to low survival rate of seedlings.

Embodiment 1

[0020] Seedlings used: Red Leaf Plum, DBH 12cm, soil ball 80cm; planting location: Jingwei Sports Center; soil characteristics: soil compaction, poor air permeability.

[0021] Planting method:

[0022] Step 1. Digging the planting hole: Dig the planting hole according to the size of the seedling soil ball. The size of the planting hole is 30cm larger than the seedling soil ball. Place a layer of pebbles with a thickness of 30cm on the bottom of the planting hole, and then spread 1000g of geotextile on the pebbles, and then Coarse sand with a thickness of 10cm is laid on the geotextile, and loess with a thickness of 30cm is filled in the planting hole; the density of the geotextile is 1000g / m 2 ;

[0023] Step 2, dilute the bactericide 500 times with water, dilute the rooting agent naphthalene acetic acid 1500 times with water, then mix the diluted bactericide and the diluted rooting agent according to the volume ratio of 1:1 and spray it on the root of the seedling soil bulb...

Embodiment 2

[0028] Seedlings used: Ligustrum lucidum, DBH 12cm, soil ball 80cm; planting location: Jingwei Sports Center; soil characteristics: soil compaction, poor air permeability.

[0029] Planting method:

[0030] Step 1. Digging the planting hole: Dig the planting hole according to the size of the seedling soil ball. The size of the planting hole is 40cm larger than the seedling soil ball. A layer of pebbles with a thickness of 20cm is placed at the bottom of the planting hole, and then 1000g of geotextile is spread on the pebbles, and then Coarse sand with a thickness of 12cm is laid on the geotextile, and loess with a thickness of 35cm is filled in the planting hole; the density of the geotextile is 800g / m 2 ;

[0031] Step 2: Dilute the fungicide 800 times with water, dilute the rooting agent Biaodian-3721 rooting solution 1000 times with water, then mix the diluted fungicide and the diluted rooting agent according to the volume ratio of 1:1 and spray on the seedlings At the ro...

Embodiment 3

[0036] Seedlings used: horse chestnut, DBH 12cm, soil ball 80cm; planting location: Jingwei Sports Center; soil characteristics: soil compaction, poor air permeability.

[0037] Planting method:

[0038] Step 1. Digging the planting hole: Dig the planting hole according to the size of the seedling soil ball. The size of the planting hole is 20cm larger than the seedling soil ball. Put a layer of pebbles with a thickness of 40cm on the bottom of the planting hole, and then spread 1000g geotextile on the pebbles, and then place the Coarse sand with a thickness of 8cm is spread on the geotextile, and loess with a thickness of 25cm is filled in the planting hole; the density of the geotextile is 900g / m 2 ;

[0039] Step 2: Dilute the fungicide 500 times with water, dilute the rooting agent Biaodian rooting powder 2000 times with water, then mix the diluted fungicide and the diluted rooting agent according to the volume ratio of 1:1 and spray on the soil bulbs of seedlings Part, ...

Abstract

The invention discloses a method for improving tree seedling survival rate, which comprises the steps of: 1) excavating planting holes: excavating the planting holes according to the size of tree seedling soil balls, laying pebbles at the bottoms of the planting holes, laying geotextiles, laying coarse sand and filling yellow soil in the planting holes; 2) planting tree seedlings; 3) supporting and binding the tree seedlings; 4) irrigating the tree seedlings: spray freshwater to the branches and the trunks of the tree seedlings before a.m. 10 o'clock of every day, spraying mixed solution of urea, potassium dihydrogen phosphate and water to the branches and the trunks of the tree seedlings after p.m. 5 o'clock of every day, continuously irrigating for 1-2 months and finally conducting normal irrigation to the tree seedlings. The method for improving tree seedling survival rate has the advantages that the resuming growth time of the tree seedlings can be shortened, not only can the situations that roots cannot grow because water cannot seep into the tree seedlings and the tree seedlings are dead because the supply and the demand are unbalanced be avoided, but also the water and the temperature at the roots of the tree seedlings can be preserved, the tree seedlings can root rapidly, the supply and the demand are balanced, the survival rate of the tree seedlings is improved, the death rate of the tree seedlings is reduced, the cost is decreased and a feasible method is provided for the planting of garden tree seedlings.

Description

technical field [0001] The invention belongs to the technical field of seedling cultivation, and in particular relates to a method for improving the survival rate of seedlings. Background technique [0002] The technology and method of seedling planting should be widely used in garden engineering. During the planting of seedlings, it is often encountered that the geological soil is compacted, the water permeability is poor or impermeable, so that the root system of the seedlings cannot take root, or the planting period of the seedlings is too late, the planting period has passed, drought, less rain, low temperature, low air humidity, and the seedlings are easy to appear. Dehydration of tree trunks, cracks on the ground surface, freezing of roots and other conditions lead to low survival rate of seedlings planted. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for improving the survival rate of seedling...
