Desert rice field ecological system

Abstract

The invention discloses a desert rice field ecological system, and belongs to the field of agricultural ecology. Fresh water is used for desert salt elimination by means of a water transfer project, an ecological system with rice as a main body is built, and the problems that the soil fertility of a traditional rice field ecological system is reduced year by year, the environment is deteriorated, and the ecology is degraded are solved. The technical key to solve the problems is that the salt content of the rice field is gradually reduced through fresh water washing, salt drying, salt collection and salt content gradual reduction, excrement enters a pond to prepare fertilizer through retting, straw is fed to cattle, rice chaff is fed to pigs, interference of farmland interference factors is reduced, cleanliness of well water is guaranteed through the filtering effect of pelelith, daily detergent waste liquid is guided into closed tree root soil through a pipeline, and health and safety of an ecological system are kept by forbidding use of harmful chemical compounds, hybrid varieties and transgenic varieties. The desert rice field ecological system is used for desert environment reconstruction and green agricultural ecological system construction.

Description

technical field [0001] The invention relates to a paddy field ecosystem, in particular to a desert paddy field ecosystem. Background technique [0002] Swamp wetlands can use ditching, pumping, and leveling techniques to create fertile land, and the Great Northern Wilderness has been developed into "Beidacang", but this technique is not suitable for deserts. The desert lacks water and organic matter, and some desert plots contain salt. The rice field ecosystem is a man-made agricultural ecosystem. Separation of salt water in saline-alkali land is a difficult problem. Using existing irrigation technology to irrigate and cultivate saline desert land will lead to the formation of saline-alkali land, which cannot be cultivated or the yield of cultivation is low. Existing technologies lack the technology to transform deserts into rice paddy ecosystems. [0003] Disadvantages of the existing rice field ecosystem include: intensive cultivation of traditional rice fields leads to...

AI Technical Summary

Problems solved by technology

Separation of salt water in saline-alkali land is a difficult problem. Using existing irrigation technology to irrigate and cultivate saline desert land will lead to the formation of saline-alkali land, which cannot be cultivated or has low yield

Existing technology lacks technologies to transform deserts into rice paddy ecosystems

[0003] Disadvantages of the existing rice field ecosystem include: intensive cultivation of traditional rice fields leads to yearly degradation of farmland soil fertility; burning of crop straw pollutes the environment; low benefit and high cost of returning crop straw to the field; biogas retting of crop straw is burning straw in disguise, wasting humus resources and feed resources; traditional paddy fields are inconvenient for irrigation and drainage; traditional paddy fields are easily affected by factors such as weed seeds, pests, pests, pests, pathogenic bacteria, sewage, peripheral invasive species, human behavior, and livestock trampling; laundry, bathing, washing dishes, etc. Daily detergent solution flows into ponds or farmland; buffalo soaking in water in summer pollutes ponds and poisons fish; pig manure is rich in intestinal flora and pollutes the environment with rainwater; farmland biomass is transported to composting sites and composted into fertilizer Transportation to farmland, the transportation cost of this composting process is relatively high; herbicides, pesticides, ripening agents, antibiotics, pesticides, hybrid rice, genetically modified varieties, etc. endanger the ecological environment, food health and the sustainability of agricultural development; the area of ​​rice fields and The shape restricts large-scale mechanized operations; there are hidden dangers that rice seeds cannot be self-sustained; cattle do not like to eat hybrid rice straw; lack of desert salt drainage technology; lack of scientific combination and layout of rice field ecosystem functional areas
