Embodiment 1

[0052] 1 land consolidation

[0053] The project construction was started in Dubai on January 8, 2018, and land consolidation began.

[0054] step:

[0055] 1) Plot construction: bulldozer leveling (removing gravel)—excavator excavating the pond (the depth of the pond is 0.8m)—cement building the four walls of the pond—laying 1.2mm thick black HDPE geomembrane (made of thermoplastic resin material) at the bottom and around it - made of polyethylene resin) - laying water circulation device at the bottom - laying drainage cushion (gravel) - backfilling with sand. Guarantee the irrigation of the test planting pool, controllable drainage and water and fertilizer circulation, and backfill the sand to truly restore the desert state.

[0056] 2) Soil improvement

[0057]The sandy soil in the desert lacks soil aggregate structure, and the content of organic matter and microorganisms is extremely low. The soil is improved by applying organic matter, 0.8-1 ton per mu, in which the or...

Abstract

The invention discloses a method for planting rice in desertified soil, and belongs to the technical field of rice planting. The method for planting the rice in the desertified land comprises the steps of land preparation, seed selection and seedling raising and management, manual rice seedling transplantation, field management after rice seedling transplantation, yield monitoring, harvesting andthe like. By means of the method for planting the rice, the problem that the rice is planted in a desert can be solved, the yield of the rice planted by means of the method is up to 520 kg / mu, and a solution can be provided for the problem that food crops in countries in a desert region cannot be self-sufficient.

Description

technical field [0001] The invention belongs to the technical field of rice planting, and in particular relates to a method for planting rice in desertified soil. Background technique [0002] Rice is one of the most important food crops. Nearly half of the world's population feeds on rice. In addition to being edible, rice can also be used for wine making, sugar refining, and as industrial raw materials, and rice husk and rice straw can be used as feed. [0003] Dubai is basically located in the middle of the Middle East, on a flat desert land facing the Persian Gulf. The latitude and longitude are: 25°15′47″ north latitude; 55°17′50″ east longitude.
