Problems solved by technology

[0003] Coastal saline-alkali land has a large area, high soil salinity, high groundwater salinity and relatively shallow buried depth, especially in low-lying saline-alkali land with poor drainage. Plants are harmed by both salt damage and waterlogging, which makes it difficult for plants to grow seedlings in low-lying saline-alkali land. , production growth retardation, low yield

Embodiment 1

[0027] A method for planting alfalfa in low-lying saline-alkali land, carried out according to the following steps:

[0028] A. Dig a big pit in the center of the low-lying saline-alkali land, dig a large conical pit per mu, and the upper surface area is 3-5m 2 , the lower surface area is 6-8m 2 , the depth is 2-3m, use the excavated soil to raise the ground around the deep pit by 5-10cm;

[0029] B. Dig a water collection well with a diameter of 1m in the middle of the pit, the depth of which reaches the groundwater, and the rest of the pit is filled with the original soil layer, fine sand layer, and gravel layer in sequence from high to low; the final height is flush with the surrounding areas;

[0030] C. 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; the distance between the hidden pipes is 5 meters, the buried depth is 1.2 meters, the length is 14 meters, and the slope ratio ...

Abstract

The invention provides a method for planting Medicago sativa in low-lying saline-alkaline land. The problems, i.e., salt damage and flooded damage of low-lying saline-alkaline land regions are solved by means of burying concealed pipes, excavating water treatment pits so as to carry out filtering and saline matter isolation on water and excavating water collecting wells leading to underground water so as to drain, and meanwhile, a purpose-made microbial fertilizer is adopted, so that the agricultural damage to the Medicago sativa is low, and the yield is high; and by the method, large-labor-amount farm work such as ploughing is not required to be carried out every year, the annual income increases gradually, and the saline-alkaline land can be reclaimed into fertile farmland in 3 to 5 years.

Description

technical field [0001] The invention relates to the technical field of improving saline-alkali land, in particular to a method for planting alfalfa in low-lying saline-alkali land. 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 and alkalized soil in my country is m...
