Embodiment 1

[0029] A method for growing rice in a large area in a desert area, specifically including the following methods,

[0030] Step (1): Pour sand and make borders: In order to facilitate mechanical farming, a new plot of 100 acres in the Badain Jaran Desert, Pingchuan Township, Linze County, Gansu Province, at an altitude of 1,446 meters, is 3 hectares each, that is, a block of 150m×200m. To determine the long side of the plot, use an excavator to dig out a trapezoidal trench with a depth of 80cm and a width of 5m as the first border to make the border bottom super flat;

[0031] Step (2): Paving anti-seepage soil: Spread 10cm thick swamp soil evenly on the bottom of the ditch, with soil bulk density ≥1.64g / cm 3 , The porosity ≤ 37.8% is used as the impermeable soil. Use a sprinkler to sprinkle water on the impermeable soil, roll it with a road roller, sprinkle water, and then roll until the impermeable soil is tightly combined and connected as a whole, smooth and seamless. There is no...

Embodiment 2

[0040] A method for growing rice in a large area in a desert area, specifically including the following methods,

[0041] Step (1): Pour the sand and make the border: In order to facilitate mechanical farming, a new plot of 100 acres in the Badain Jaran Desert, Pingchuan Township, Linze County, Gansu Province, at an altitude of 1,446 meters, is 3 hectares each, that is, a block of 150m×200m. Use an excavator to dig out a trapezoidal trench with a depth of 85cm and a width of 6m along the long side of the determined plot as the first border, making the bottom of the border super flat;

[0042] Step (2): Paving anti-seepage soil: Spread 12cm thick swamp soil evenly on the bottom of the ditch and the soil bulk density ≥1.64g / cm 3 , The porosity ≤ 37.8% is used as the impermeable soil. Use a sprinkler to sprinkle water on the impermeable soil, roll it with a road roller, sprinkle water, and then roll until the impermeable soil is tightly combined and connected as a whole, smooth and sea...

Abstract

The invention relates to a method for large-area land preparation and rice plantation in desert areas. A large-area plantation structure subjected to land preparation comprises a base layer, an anti-seepage layer and an improved matrix layer from bottom to top, wherein the base layer refers to original desert soil, the anti-seepage layer is a tamped boggy soil layer, the bottom of the boggy soil layer is in close adhesion with the base layer, and the improved matrix layer is formed by mixing of fermented pig manure, mushroom residues and the original desert soil. Specifically, the large-area plantation structure is formed by sand pouring for furrowing, paving of the anti-seepage layer, additional arrangement of ridges and sand field improvement. By adoption of the method, the problem of water seepage is well solved, breathability is achieved by adoption of the tamped boggy soil as the anti-seepage layer, and large-area rice plantation in deserts is realized. The rice plantation method high in yield and efficiency and low in water consumption is provided on the basis of the deserts.

Description

Technical field Technical field [0001] The invention belongs to agricultural ecological planting, relates to desert ecological restoration, and specifically relates to a method for large-area land preparation in desert areas and rice planting. Background technique [0002] In the process of ecological restoration, how to effectively manage arid desert areas has become the most urgent problem to be solved in our country; desertification has brought great harm to people, and desertification has caused the land to be dry and unsuitable for cultivation. The mission of sand prevention and control is glorious, the task is arduous, and the task is heavy and long. Rebuilding one mu of sand is equivalent to adding one mu of farmland. At present, in the treatment of arid desert areas, vegetation is mainly planted on the surface of the desert. When the vegetation survives, the roots of the plants are used to stabilize the sand, prevent rain and wind from taking away the sand, and protect...
