Embodiment 1

[0017] A method for improving the survival rate of saline-alkali soil jujube by using biological bacterial fertilizer, comprising the steps of:

[0018] Step 1: Detect the salt content of the soil surface, and peel off 20cm of the soil layer according to the detected soil salt content;

[0019] Step 2: Plow the land. In spring and autumn, plow the saline-alkali land to a depth of 5cm, kill bacteria and insects, and remove weeds;

[0020] Step 3: wash salt with fresh water, dig trenches and ditches reasonably according to the terrain, lay underground pipes, and use the stored fresh water to wash salt on the saline-alkali land that needs to be improved, and remove most of the saline-alkali dissolved in water through the laid underground pipes;

[0021] Step 4: Apply crushed crop stalks in the saline-alkali land, plow, and measure the surface temperature. When the surface soil temperature reaches 5°C, plant Elsewhere;

[0022] Step 5: configure microbial bacterial agents, separa...

Embodiment 2

[0029] A method for improving the survival rate of saline-alkali soil jujube by using biological bacterial fertilizer, comprising the steps of:

[0030] Step 1: Detect the salt content of the soil surface, and peel off the soil layer by 30cm according to the detected soil salt content;

[0031] Step 2: Plow the land. In spring and autumn, plow the saline-alkaline land to be improved to a depth of 8cm, kill bacteria and insects, and clear and bury weeds;

[0032] Step 3: wash salt with fresh water, dig trenches and ditches reasonably according to the terrain, lay underground pipes, and use the stored fresh water to wash salt on the saline-alkali land that needs to be improved, and remove most of the saline-alkali dissolved in water through the laid underground pipes;

[0033] Step 4: Apply crushed crop stalks in the saline-alkali land, plow, and measure the surface temperature. When the surface soil temperature is 5°C, plant Elsewhere;

Embodiment 3

[0041] A method for improving the survival rate of saline-alkali soil jujube by using biological bacterial fertilizer, comprising the steps of:

[0042] Step 1: Detect the salt content of the soil surface, and peel off 40cm of the soil layer according to the detected soil salt content;

[0043] Step 2: Plow the land. In the spring and autumn, plow the saline-alkali land to be improved to a depth of 10cm, kill bacteria and insects, and clear and bury weeds;

[0044] Step 3: wash salt with fresh water, dig trenches and ditches reasonably according to the terrain, lay underground pipes, and use the stored fresh water to wash salt on the saline-alkali land that needs to be improved, and remove most of the saline-alkali dissolved in water through the laid underground pipes;

[0045] Step 4: Apply crushed crop stalks in the saline-alkali land, plow the fields, and detect the surface temperature. When the surface soil temperature is 7°C, plant Elsewhere;

Abstract

The invention relates to the technical field of improvement of saline-alkali soil and provides a method for increasing the survival rate of elaeagnus angustifolia on saline-alkali soil by using biological bacterial fertilizer. The method comprises the following steps that 1, the salt content of the soil surface is detected; 2, the soil is ploughed, disinfection and insect killing are conducted, and weeds are removed; 3, salt-leaching is conducted through fresh water, ditching and channeling are reasonably conducted according to the terrain, and most water-soluble salt and alkali are removed through laid underground pipes; 4, smashed crop straw is applied to the saline-alkali soil, ploughing is conducted, and elaeagnus angustifolia is planted; 5, a microbial agent is prepared, an organic acid chelate generated through chelation of organic acid is added to the prepared microbial agent, and stable liquid fertilizer is prepared; 6, the underground pipes laid in the third step are replacedby drip irrigation pipes, planted elaeagnus angustifolia is directly subjected to drip irrigation through the drip irrigation pipes, and accordingly the survival rate of elaeagnus angustifolia is increased.

Description

technical field [0001] The invention relates to the technical field of saline-alkali soil improvement, in particular to a method for improving the survival rate of saline-alkali soil jujube by utilizing biological bacterial fertilizer. Background technique [0002] Eleuthero jujube is the most common tree species in Northwest China, and it can tolerate saline soil dominated by sulfates. Elaeoptera also has the effect of reducing soil salinity. According to the measurement, Elaeoptera has a strong salt-tolerant ability. Although the growth is inhibited, it can still form a forest after good tending and management. Therefore, according to the salt-tolerant ability of Eleuthero jujube, it can be planted on unimproved medium and heavy salinized soil. The high salt tolerance of Elaeoptera has made it the main tree species for constructing farmland shelterbelts in saline-alkali land. [0003] Jujube tree has strong vitality and has the characteristics of drought resistance, wind...
