Problems solved by technology

Although Limonium Limonium can grow in a saline environment, seed germination and emergence in a saline environment are the key and sensitive stages of the growth of halophytes, and the germination rate of its seeds is reduced due to salt stress

Embodiment 1

[0019] Example 1 (Fukang Desert Ecological Station, Chinese Academy of Sciences)

[0020] a. Site selection and site preparation:

[0021] Select a flat plot with a salt content of 1.5% in the 0-20cm soil layer, and plow and harrow to ensure that the sowing soil is finely divided and flat;

[0022] b. Structural ridge topography:

[0023] Ditch and ridge in a parallel direction, the distance between the bottom of the ditch is 0.6m, the depth is 0.2m, and the width of the ridge is 0.2m. The ridge slope is smoothed, and the terrain of the ridge is constructed. The furrow is 5.0m long and 3.0m wide, and the soil ridge around the furrow should be high. On the furrow surface;

[0024] c. Irrigation management:

[0025] Before planting, the head water treatment is carried out, and the head water is treated with flood irrigation in the border. The water in the border should overflow the ridge surface. The water in the head water disappears completely 3 days after the second irriga...

Embodiment 2

[0028] Example 2 (Xiaguai Township, Karamay)

[0029] a. Site selection and site preparation:

[0030] Choose a flat plot with a salt content of 2.0% in the 0-20cm soil layer, and plow and harrow to ensure that the sowing soil is finely divided and flat;

[0031] b. Structural ridge topography:

[0032] Ditch and ridge in a parallel direction, the distance between the bottom of the ditch is 0.6m, the depth is 0.3m, and the width of the ridge is 0.3m. The ridge slope is smoothed, and the terrain of the ridge is constructed. The furrow is 5.0m long and 3.0m wide, and the soil ridge around the furrow should be high. On the furrow surface;

[0033] c. Irrigation management:

[0034] Before sowing, the head water treatment is carried out, and the head water is treated with flood irrigation in the furrow. The water in the furrow should overflow the ridge surface. The water in the head water will be watered for the second time 5 days after the water disappears completely. Keep th...

Embodiment 3

[0037] Example 3 (Caramay Carbon Sink Forest Base)

[0038] a. Site selection and site preparation:

[0039] Select a flat plot with a salt content of 2.5% in the 0-20cm soil layer, and plow and harrow to ensure that the sowing soil is finely divided and flat;

[0040] b. Structural ridge topography:

[0041] Ditch and ridge in a parallel direction, the distance between the bottom of the ditch is 0.6m, the depth is 0.2m, the width of the ridge is 0.3m, and the slope of the ridge is smoothed, and the terrain of the ridge is constructed. The furrow is 5.0m long and 3.0m wide. On the furrow surface;

[0042] c. Irrigation management:

[0043] Before sowing, the head water treatment is carried out, and the head water is treated by flood irrigation in the border. Keep the soil in the ditch moist at a degree across the sowing line, and after the Limonium hemophilus emerges, regularly irrigate to keep the soil in the ditch moist;

[0044] d. Sowing:

[0045] On May 27, 2014, af...

Abstract

The invention relates to a cultivation method of seedlings of limonium gmelinii of saline-alkali soil in an arid region. The method comprises the steps of digging parallel shallow ditches in the saline-alkali soil, and making rectangular pieces of land in the field according to a certain area; carrying out flood irrigation and furrow irrigation on the rectangular pieces of land in the field, eluting salinity to enable a seedbed to be in a low-salt state, and further simulating the naturally occurring conditions of the seedlings; guaranteeing the successful planting of the seedlings of the limonium gmelinii by 'furrow irrigation and seeding in water'. The cultivation method is respectively used for planting tests in Karamay Xiaoguai township, Fukang desert ecology station of Chinese academy of science and Karamay carbon sink forest base, and the tests prove that the seedling rates of the limonium gmelinii are more than 70%, so that the technological reserve is accumulated for greening and beautifying the saline-alkali soil in the arid region.

Description

technical field [0001] The invention belongs to the field of ecological planting, and relates to a method for cultivating seedlings of the halophyte Limonium macrophylla in saline-alkali land in arid areas. Background technique [0002] my country has a large area of ​​saline-alkali soil, and the total area of ​​various saline-alkali soils in the country reaches 1 million km 2 , about 100 towns are distributed with saline-alkali land. With the expansion of cities and the needs of industrial layout, some new towns, new industrial parks, processing trade zones and logistics centers are also being built on saline-alkali land. However, land saline-alkali brings great difficulties to the greening and beautification of urban areas. Generally speaking, when the salt content of the soil surface exceeds 0.6%, most plants cannot grow normally. When the soluble salt content exceeds 1.0%, only some plants specially adapted to saline soil can grow. Therefore, the selection and cultivati...
