Embodiment 1

[0030] A method for improving microorganisms in severely saline-alkali land and planting Elaeoptera sativa, carried out according to the following steps:

[0031] A. Hidden pipe buried in the field: the diameter of the hidden pipe is 12cm, and seepage holes are set on the surrounding wall of the hidden pipe; For water wells, check and adjust the pH value of the water collection wells to keep the pH value between 6.5-7.0;

[0032] B. Block the water collection port of the water collection well at the end of the hidden pipe, use the water in the water collection well to soak the field, the water surface is 1-1.5cm higher than the soil surface, and drain the accumulated water into the water collection well after 3 days of soaking;

[0033] C. Sprinkle superphosphate and microbial fertilizer A evenly on the land, and use deep plowing to plow and level the soil, and the plowing depth is 50-60cm;

[0034] D, dig a planting pit, lay an isolation layer at the bottom of the pit, and t...

Abstract

The invention provides a severe saline-alkaline land microorganism improvement and elaeagnus angustifolia planting method. Aiming at the characteristics that severe saline-alkaline land is high in salinity and alkalinity and not suitable for crop survival, microorganism improvement and concealed conduit salt elimination are combined, saplings resistant to salt and alkali are planted firstly, salt elimination is carried out step by step, soil is improved, cost is greatly reduced, economic benefits are increased, the severe saline-alkaline land can be improved into fertile farmland usually within 4-7 years, and then other trees can be planted in a mixed mode.

Description

technical field [0001] The invention relates to the technical field of improvement of saline-alkali land, in particular to a method for microbial improvement of severe saline-alkali land and planting of sandy dates. Background technique [0002] Saline-alkali land is the general term for salt land and alkaline land. Saline soil mainly refers to salinized soil with high chloride or sulfate content. The soil is alkaline, but the pH value is not necessarily high. Alkaline soil refers to the soil containing carbonate or heavy phosphate, the pH value is high, and the soil is alkaline. The content of organic matter in saline-alkali land is low, the soil fertility is low, the physical and chemical properties are poor, and there are many anions and cations harmful to crops, so it is difficult for crops to promote seedlings. The area of ​​saline-alkali land in the world is 954.38 million hectares, of which 99.13 million hectares are in my country. The formation of alkaline land an...
