Embodiment Construction

[0018] Lay plastic bags with a length of 1.5 meters and a width of 1 meter flat, spread a soil layer 20 centimeters thick, 1.2 meters long and 50 centimeters wide, and use four bamboo slices to form an arch shed. Plant 60 pumpkin seeds at the beginning of February, pour appropriate amount of water, tie the mouth of the bag tightly with rubber, and put it on the roof, which is quite a small airtight shed. Turn it on in the morning one week after the first time, do 20 minutes of ventilation, and turn it off. After another 3 days, the melon seedlings have emerged. Turn on the ventilation for 20 minutes in the morning. After that, turn on the ventilation for 20 minutes every morning. After 3 days, water once. After another 5 days, they can be transplanted into the field. Local early pumpkins are generally grown in mid-February. Due to the large temperature difference between day and night, a layer of plastic film is covered on the soil layer to keep warm, and watered every 3 days ...

Abstract

The invention discloses a device for saving water in agriculture and controlling deserts, and relates to the fields of agricultural water conservation and environmental protection. An impermeable membrane is paved in the soil of a desert, an arid area and a semiarid area to prevent penetration of dampness; a sealed tent is used so as to prevent evaporation of water; the agricultural production is carried out in the impermeable and anti-evaporation sealed tent; and an impounding reservoir is built to collect rain water and snow water, and a windbreak facility is used to stop wind, so that the device can be used for the agricultural production in any desert, arid area and semiarid area. Through the device, a large amount of farmlands are increased to solve the worldwide food crisis, more farmlands in China can be developed so as to produce a large amount of green agricultural products and avoid the vegetable shortage in winter in northern area, the deserts and sandstorms are controlled, carbon dioxide content in air is reduced, tourist income is increased, wind power generation is greatly improved, and the sustainable economic development is ensured.

Description

technical field [0001] The invention relates to the fields of agricultural water saving and environmental protection, more specifically, a facility for agricultural water saving and desert control. Background technique [0002] China has a large population and shortage of arable land. The world, especially the arid African regions, is facing a food crisis. In China, arid, semi-arid and desert areas occupy a large area. If they are developed into arable land, they can exceed the current arable land area. Desertification is a difficult problem facing the world. Due to the destruction of the ecological environment and natural reasons, sandstorms occur every year. The cities and villages in Northwest China and North China are attacked, affecting the living environment of human beings, endangering people's health, property and life safety, and affecting the spring season. tourism income. The country invests a lot of money every year to control deserts and sandstorms, but there i...
