Embodiment 1

[0040] Embodiment 1 introduces flowers and carries out coastal heavy saline-alkali land original soil greening method

[0041] Step 1 Saline-alkali land selection

[0042] During the period from 2011 to 2016, the test site was located in the coastal heavy saline-alkali land in the north of Weifang City, Shandong Province. The pH of the surface soil layer was 8.6, and the total salt content was determined to be 0.53%. The thickness of the soil was more than 1 meter. Alkali weeds, no shrub or tree vegetation growth, and the perennial sandstorm environment poses a serious threat to plant growth, so the plant species are poor and the soil development is weak.

[0043] Step 2 Laying the salt discharge underground pipe

[0044] Remove the weeds in the saline-alkali land in the green area, and dig a 1m deep pipe embedding ditch in the green area. The overall water intake area is 30cm² / m. Wrap coarse sand and other filter materials around the hidden pipe, with a thickness of 5cm; ...

Embodiment 2

[0072] Embodiment 2 introduces flowers and carries out coastal heavy saline-alkali land original soil greening method

[0073] Step 1 Saline-alkali land selection

[0074] The test site is located in the coastal heavy saline-alkali land in the north of Weifang City, Shandong Province. The pH of the surface soil layer is 8.5, and the total salt content is 0.54%. The thickness of the soil is more than 1 meter. Or the growth of arbor vegetation, the perennial wind and sand environment poses a serious threat to plant growth, so the plant species are poor and the soil development is weak.

[0075] Step 2 Laying the salt discharge underground pipe

[0076] Remove the weeds in the saline-alkali land in the green area, dig a 1.1m deep pipe embedding ditch in the green area, the buried pipe distance is 5.5m, and the buried pipe slope is controlled at 0.32‰; It can ensure that the overall water inlet area is 32 cm² / m. Wrap coarse sand and other filter materials around the hidden pipe...

Embodiment 3

[0104] Embodiment 3 introduces flowers and carries out coastal heavy saline-alkali land original soil afforestation method

[0105] Step 1 Saline-alkali land selection

[0106] The test site is located in the coastal heavy saline-alkali land in the north of Weifang City, Shandong Province. The pH of the surface soil layer is 8.6, the total salt content is 0.55% after measurement, and the thickness of the soil is more than 1 meter. Or the growth of arbor vegetation, the perennial wind and sand environment poses a serious threat to plant growth, so the plant species are poor and the soil development is weak.

[0107]Step 2 Laying the salt discharge underground pipe

[0108] Remove the weeds in the saline-alkali land in the green area, dig a 1.2m deep pipe embedding ditch in the green area, the buried pipe distance is 6m, and the buried pipe slope is controlled at 0.35‰; Ensure that the overall water inlet area is 33 cm² / m. Wrap coarse sand and other filter materials around th...

Abstract

The invention provides a method introducing flowers to afforest coastal severely-saline-alkali original soil. The method includes: laying salt-discharge hidden pipes, wherein the hidden pipes are provided with circular water inlets to guarantee that overall water inlet area is 30-33cm<2> / m, hidden pipe burying ditches 1-1.2m in depth are excavated in an afforestation area, the burying interval of the hidden pipes is 5-6m, the burying slope of the hidden pipes is controlled to be 0.3-0.35%o, filtering materials are used to wrap the hidden pipes, and wrapping thickness is 5-8cm; covering the laid hidden pipes with 20cm saline-alkali original soil; planting chaenomeles speciosa, planting Zinnia elegans Jacq., and performing management after planting. The method is high in afforestation survival rate, high in saline-alkali soil afforestation ornamental value, high in flowering amount and long in flowering period.

Description

technical field [0001] The invention relates to a method for afforesting saline-alkali land, in particular to a method for introducing flowers to perform original soil afforestation in heavy saline-alkali land along the coast. Background technique [0002] At present, many related cities in China, such as Tianjin Binhai New Area, Yellow River Delta Area, Hangzhou Bay New Area, etc., often use the engineering salt avoidance measures of "isolation layer + foreign soil" to reduce the groundwater level, reduce the salt content of the soil, and make the soil contain After the salt content is controlled below 0.4%, the landscaping and green space construction will be carried out. Although the above measures have achieved some results, there are still serious problems. One is that not only the high cost and high maintenance cost have laid various hidden dangers for the later maintenance and management, but also because of foreign soil planting, a large amount of good land will be ...
