Embodiment 1

[0023] A method for comprehensive improvement of saline-alkali land, in which a saline-alkali land planting system, a soilless cultivation system, an animal husbandry system and an aquaculture system are interconnected for circulation, wherein:

[0024] In the first year, after cleaning up about 10cm of garbage, hardened cement, slag and other wastes on the surface of the severe saline-alkali land with a pH value of 10.3, backfill with 8cm thick coarse sand, and lay sprinkler irrigation facilities on the saline-alkali land, and dig around the land. Drainage ditches were set up, and corn was planted in the treated severe saline-alkali land with a pH value of 10.3 for the first time. Regardless of corn harvest, corn stalks were used as silage for livestock in the animal husbandry system, and 95% of the feces produced by livestock were returned to the In the saline-alkali land planting system, 5% is transported to the lotus pond after the excess water is discharged from the aquacu...

Embodiment 2

[0033] A method for comprehensive improvement of saline-alkali land, in which a saline-alkali land planting system, a soilless cultivation system, an animal husbandry system and an aquaculture system are interconnected for circulation, wherein:

[0034]In the first year, after cleaning up about 10cm of waste, compacted cement, slag and other wastes on the surface of moderate saline-alkali land with a pH value of 9.4, backfill with 5cm thick coarse sand, and lay sprinkler irrigation facilities on the saline-alkali land. Digging and setting up drainage ditches, planting sunflowers in moderately saline-alkali soil with a pH value of 9.4 for the first time, regardless of the sunflower harvest, using sunflower stalks as silage for livestock in the animal husbandry system, and 96% of the feces produced by livestock are decomposed Returning to the saline-alkali land planting system, 4% is transported to the aquaculture system. In the lotus pond and fish pond of the aquaculture system,...

Embodiment 3

[0043] A method for comprehensive improvement of saline-alkali land, in which a saline-alkali land planting system, a soilless cultivation system, an animal husbandry system and an aquaculture system are interconnected for circulation, wherein:

[0044] In the first year, after cleaning up about 10cm of waste, hardened cement, slag and other wastes on the surface of moderate saline-alkali land with a pH value of 8.7, backfill with 3cm-thick coarse sand, and lay sprinkler irrigation facilities on the saline-alkali land. Drainage ditches were dug, and sorghum was planted in the moderately saline-alkali land with a pH value of 8.7, and the grains were not harvested. The sorghum straw was used as silage for livestock in the animal husbandry system, and 92% of the manure produced by the livestock was returned after being decomposed To the saline-alkali land planting system, 8% is transported to the aquaculture system. In the lotus pond and fish pond of the aquaculture system, there ...

Abstract

The invention discloses a comprehensive saline-alkali land improvement system and a comprehensive saline-alkali land improvement and belongs to the technical field of land treatment. According to the system and the method, stems of alkali-resistant crops are utilized as silage so as to be eaten by domestic animals of a herding system, faeces generated by the domestic animals are thoroughly decomposed, then most of the faeces is returned to a saline-alkali land planting system, a small part of the faeces is conveyed to an aquaculture system, water in the aquaculture system is diverted to the saline-alkali land planting system so as to be used for irrigating a saline-alkali land, and lotus leaves in the aquaculture system as well as used culture medium and old crop leaves in a soil-less cultivation system are returned to the saline-alkali land planting system. The comprehensive saline-alkali land improvement system and the comprehensive saline-alkali land improvement method integrates ecological exploitation, livestock breeding, aquaculture, agriculture planting, agricultural technology popularization and sightseeing tour, have the advantages of short saline-alkali land improvement period, good effect and the like, and have wide application prospect and important practical significance.

Description

technical field [0001] The invention belongs to the technical field of land management, and in particular relates to a comprehensive saline-alkali land improvement system and a corresponding improvement method. Background technique [0002] Saline-alkali land refers to the soil that contains a high concentration of soluble salts in the soil, which directly inhibits or harms the growth of plants. According to the incomplete statistics of UNESCO and FAO, 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 soil and alkalized soil in my country is mostly related to the accumulation of carbonate in the soil, so the degree of alkalization is generally high, and plants in severe saline-alkali soil areas can hardly survive. Although there are various improvement measures for saline-alkali land at present, the effect is often not ideal, and the cost is high, the improvement cycle of sa...
