Embodiment 1

[0027] Collected Willow seeds in the ridge habitat of the shell beach and sown them in the soil of the glass greenhouse. In the first year, the average water content of the deep soil layer 30cm below the soil surface is maintained at about 60% of the field water holding capacity, which guarantees the basic of Willow seedlings. Growth, reduce the lengthening and vines of Willow seedlings, timely pruning after vines are found, and reduce the soil moisture content in time.

[0028] From the second year onwards, the planting density of Willow seedlings will be thinned. The planting density of Willow seedlings shall be 20cm×20cm. After the planting of Willow seedlings, the soil moisture content should be maintained at about 40% of the field water holding capacity. The determination of specific water content can promote The root system of the willow seedlings grows deep, and can inhibit the vine of the willow seedlings, and promote the sprouting and tillering of the willow seedlings. At...

Embodiment 2

[0037] Collect the Willow sylvestris seeds in the shell beach ridge habitat and sow them in the soil of the glass greenhouse. In the first year, maintain the average water content of the 30cm deep soil layer under the soil surface to be about 70% of the field water holding capacity, which guarantees the basics of the saplings Growth, reduce the lengthening and vines of Willow seedlings, timely pruning after vines are found, and reduce the soil moisture content in time.

[0038] From the second year onwards, the planting density of Willow seedlings is 30cm×30cm. After planting the Willow seedlings, the soil moisture content should be maintained at about 55% of the field water holding capacity. The determination of the specific water content can promote The root system of the willow seedlings grows deep, and can inhibit the vine of the willow seedlings, and promote the sprouting and tillering of the willow seedlings. At the same time, combine pruning to control the vine and leggy gr...

Embodiment 3

[0047] Collect the Willow seeds in the ridge habitat of the shell beach and sow them in the soil of the glass greenhouse. In the first year, maintain the average water content of the 30cm deep soil layer below the soil surface to be about 65% of the field water holding capacity. Growth, reduce the lengthening and vines of Willow seedlings, timely pruning after vines are found, and reduce the soil moisture content in time.

[0048] From the second year onwards, the planting density of Willow seedlings is 25cm×25cm. After planting the Willow seedlings, the soil moisture content should be maintained at about 50% of the field water holding capacity. The determination of specific water content can promote The root system of the willow seedlings grows deep, and can inhibit the vine of the willow seedlings, and promote the sprouting and tillering of the willow seedlings. At the same time, combine pruning to control the vine and leggy growth of the willow seedlings.

Abstract

The invention provides a propagation and cultivation method of Periploca sepium Bunge in shell ridge habitat, including the steps of collecting and sowing seeds of Periploca sepium Bunge in shell ridge habitat; thinning seedlings of Periploca sepium Bunge after two years of sowing of the seeds of Periploca sepium Bunge; cutting stems of the seedlings during the time from the end of February to thebeginning of March of the third year of sowing; during the time from the third year to the fifth year of sowing of the seeds, collecting trunks of plants with one-to-two-year-old sprout tillers, andcutting the trunks into cuttings which are 13cm to 15cm in length; raising seedlings by cutting on the matrix of shell sand in cutting containers; cutting stems of corresponding seedlings of Periplocasepium Bunge during the time from the end of February to the beginning of March of the second year of seedling raising by cutting; after two to three years of seedling raising by cutting, afforestingon the specified shell ridge on March. According to the technical scheme, the survival rate of seedlings of Periploca sepium Bunge raised by cutting is increased, the survival rate of afforestation of Periploca sepium Bunge in shell ridge is increased, and revegetation of the shell ridge habitat and protection to the ecological system are facilitated.

Description

Technical field [0001] The invention relates to the technical field of propagation and cultivation of Salix sylvestris, in particular to a method for propagation and cultivation of Salix sylvestris in shell beach ridge habitat. Background technique [0002] Shell dike is unique to the silty or silty coast. It is a ridge beach formed by sand, shells and their debris transported by waves and accumulated near the high tide line. The shell dike is parallel to the coastline, and the sea side and direction The land side is all coastal saline soil, with the core part of the shell bank in the middle, which is called the "shell beach ridge". Shell dike has high natural protection value. However, due to human disturbance and wave erosion and destruction, the shell dike ecosystem still has a high risk of degradation. Carrying out vegetation restoration on the seashell dike is vital to the protection and maintenance of the shell dike ecosystem . [0003] The shell beach ridge area belongs to...
