Method for cultivation of crops

Abstract

The invention relates to a method for cultivation of crops in solid phase, air phase is under the solid phase, and water phase is under the air phase. The water and nutrition which the growth of the crops need are extracted from the liquid phase by a thin film (belt) having absorbability and transfusion function as capillary into the solid phase passing through air phase. The crops need not watering for a long time (more than 30 days) and no rotten root occurs by this method. The seawater can be used for planting by placing a molecular sieve (osmosis film) which can block the salinity but let the water molecule get past on water sucking substance at the bottom of solid phase. Thin method is suited for crops and flowers planting on desert, water surface, island, sand'stone land and space upin the air etc. The method can be used commercially.

Description

1. Technical field [0001] The invention belongs to the technical field of agricultural cultivation and relates to a crop cultivation method. 2. Background technology [0002] As we all know, it is very important to plant crops and handle the relationship between water, fertilizer, air and soil. Many engineers and technicians have worked out many ways to improve, but there are still some deficiencies. JP7-147851 announced as Japan's open patent bulletin, has introduced the cultivation method that is made of water storage vessel, water supply column, planting pot and soil, connects water and soil by water supply column under the climate of normal humidity, solves water well supply problems. But in dry climates or frequent rains, the flaws of this cultivation system are exposed. First of all, when the weather is dry, a large amount of water in the soil and water storage tanks of the cultivation system evaporates. When the water volatilized on the soil surface and the leaves ...

AI Technical Summary

Problems solved by technology

3. The vast majority of freshwater crops cannot be irrigated with seawater, which covers 71% of the earth's seawater and deserts and deserts near seawater. Today's cultivation methods need to invest a lot of cost to be able to use them

For desertification and seepage land, the current cultivation methods are pale; 4. The crops cultivated on the water surface lose a lot of fertilizer, which affects the underwater fish's demand for water quality, air and sunlight, and it is difficult to push away
