Embodiment 1

[0042] basic situation : In the spring of 2008, 12,000 pagoda trees and 10,000 poplars were transplanted in Huaming Town, Dongli District, Tianjin, with diameters at breast height of 10-15cm.

[0043] Implementation process:

[0044] one. Transplanting time

[0045] Seedlings are transplanted in March-April.

[0046] two. Transplanting preparation

[0047] Planting area preparation: The soil in this area has a salt content of 0.25%, and the groundwater table is relatively low, so no infiltration layer and dead pipe are laid.

[0048] Seedling preparation: Before transplanting, in order to prevent a large amount of evaporation from consuming nutrients in the body, trim the inner hall branches and remove more than 80% of the leaves.

[0049] three. Starting and transporting

[0050] Large trees are transplanted with soil balls. The soil balls are apple-shaped and the diameter is 8 times the diameter of the tree. Wrap the soil balls with non-woven fabrics to preven...

Embodiment 2

[0061] basic situation : In the spring of 2009, 15,000 pagoda trees were transplanted in Tianjin Development Zone. Breast diameter 10-15cm.

[0062] The soil has a saline content of 0.4% and the groundwater table is high.

[0063] Implementation process:

[0064] one. Transplanting time

[0065] Seedlings are transplanted in March-April.

[0066] two. Transplanting preparation

[0067] Planting area preparation: Lay infiltration layer in the planting area with a depth of 1-1.2m, a thickness of 10-15cm, and a slope of 1 / 1000; install blind pipes with a diameter of 8-10cm, an interval of 30 meters, and a slope of 3 / 1000. The original soil is mixed with 1 / 4-1 / 3 of cow dung or straw, and backfilled. The flood irrigation is used to discharge salt and reduce alkali, and the water volume is 120 square meters per mu.

[0068] Seedling preparation: Before transplanting, in order to prevent a large amount of evaporation from consuming nutrients in the body, trim the inner ha...

Abstract

The invention relates to a big seedling transplanting method for an inshore saline-alkali land. The method is characterized in that: the optimal time for transplanting big trees in inshore regions is spring. The method comprises the following steps of: selecting a region with soil salt content of over 0.3 percent, and paving a filter layer; installing blind pipes; backfilling original soil doped with 1 / 4 to 1 / 3 cow dung or straws; irrigating with great water to remove salt and reduce alkali, wherein the water quantity is 120 cubes per mu; cutting and trimming roots in a mode of 'cutting the main root and keeping capillary roots' in one year earlier; lifting and transporting; planting in a depth which is 10 to 15 centimeters higher than the original trunk planting earth surface line position; and performing daily management. The method has the advantages of effectively reducing underground water level, providing favorable conditions for reducing slat and improving alkali, providing an appropriate environment for the growth of plants, remarkably promoting the growth of roots of big seedlings, enhancing the growth vigor, achieving the seedling survival rate of over 90 percent and effectively solving the problem of low survival rate of the transplanted big seedlings in the saline-alkali regions.

Description

technical field [0001] The invention belongs to seedling cultivation, in particular to a method for transplanting large seedlings in coastal saline-alkali land. Background technique [0002] With the ever-changing development of modern cities and the continuous improvement of landscape environment requirements, today's landscaping projects often have to reflect the effect of greening and beautifying in a short period of time, and the big trees are tall and graceful, and transplanting big trees can Accelerate the process of urban greening and quickly show the effect of plant landscaping. Therefore, tree transplantation is also more and more used in landscaping. [0003] All trees with a DBH of 10-20 cm or more can be called "big trees" in garden engineering. The tree species that are often transplanted include: Chinese pine, white bark pine, juniper, Chinese pagoda tree, white wax, sycamore, ingot maple, cedar, acacia, Cypress, magnolia, five-needle pine, ginkgo, sweet-scen...
