Problems solved by technology

At present, the common way to grow rice in deserts is to lay film to achieve the anti-seepage effect, but there is a problem of poor air permeability, and the organic link between plants and groundwater cannot be formed. At the same time, chemical fertilizers are often used to provide nutrients, but due to the rapid flow of nutrients in sandy soil, Can't store nutrients well

[0021] 2) Production of planting ponds: Excavate a planting pond with a length×width×depth of 100m×100m×1m in the sandy land, and set a field ridge with a length×width of 100m×1m between the planting ponds;

[0022] 3) Field ridge setting: Lay biodegradable plastic film on the edge of the field ridge slope, spray 500ml / mu of sand-fixing agent on the surface of the field ridge, and set up a straw wall as a windbreak;

[0023] 4) Laying of anti-seepage layer: first lay anti-seepage water sand with a thickness of 15mm on the surface of the planting pond, and then lay an agricultural water-retaining agent with a thickness of 8mm on the anti-seepage water and sand to form an anti-seepage layer;

[0024] 5) Nutrient layer laying: lay 80mm thick earthworm-fermented sludge on the anti-seepage layer (the sludge can pass the patent No. 201210036053.X, and the name is an inve...

Abstract

The invention relates to a method for planting rice by sand, and belongs to the technical field of operation methods for desert ecological restoration. The method includes the following technologicalsteps: rice variety selection; planting pond production; field ridge setting; anti-seepage layer laying; nutrient layer laying; sand filling; water management; and later-period nutrient and water management in a conventional method. The method for planting rice by sand is reasonable in design. Compared with the prior art, the method adopts the combination of anti-seepage water sand and a water retaining agent, and at the same time, a sludge layer and a seedling culture substrate layer are laid on an anti-seepage layer, the process of 'earth making by the nature' is fully imitated, the sandy soil becomes soil, and the problems that sandy soil moves easily and it is difficult to retain water and store nutrients are solved fundamentally, the soil is more suitable for plant growth, the shape of the sandy soil is fundamentally improved, and sandy soil governance is performed. Natural moisture, nutrients and air are provided for rice planting to achieve the effect of water retention and fertilizer conservation. At the same time, the desertification problem of soil can be effectively repaired during repeated planting.

Description

technical field [0001] The invention belongs to the technical field of operation methods for desert ecological restoration, and in particular relates to a method for planting rice in sandy soil. Background technique [0002] At present, China has become one of the countries most seriously endangered by desertification in the world. Deserts make up nearly 20 percent of China's landmass and are expanding at a rate of more than 1,300 square miles (3,367 square kilometers) a year. China's desert area is 21,000 square miles (54,390 square kilometers) larger than it was in 1975—about the size of Croatia. [0003] In ecological restoration, how to effectively control arid desert areas has become the most urgent problem that needs to be solved in our country at present; desertification has brought great harm to people, and desertification has led to the depletion of land that is not suitable for farming. Transforming an acre of sandy land is equivalent to adding an acre of fertile...
