Watering means, prepn. method and application method thereof

Abstract

A water leading body for planting tree is composed of an external tube made of plastic film and the hydroscopic material (soil particles or sludge) filled in said external tube. Its application includes such steps as digging a pit, drilling a deep hole on the pit bottom, putting said water leading body in it, planting a tree in the pit, and irrigating sufficient water.

Description

technical field [0001] The invention relates to a device for supplying water to plants in the field of forestry and agriculture and its preparation method and application, in particular to a water diversion body and its preparation method and application method. Background technique [0002] With the development of society and the advancement of science and technology, people's ability to conquer and transform nature is gradually improving. In the process of conquering and transforming nature, people have caused great damage to the natural environment. Now people have realized this serious problem. In the arid regions of western my country, the annual precipitation is less than 100 mm, while the evaporation is above 1500 mm. The survival rate and preservation rate of afforestation in these areas are very low, which causes tree planting to be carried out every year, that is, the phenomenon of no forest. A common feature of these arid areas is that the dry soil layer on the ...

AI Technical Summary

Problems solved by technology

Especially in summer, the temperature on the ground is high, and the humidity in the ground evaporates quickly, which has an extremely adverse effect on the survival rate of seedlings. The above-mentioned problems also exist in agricultural production.

[0003] Now there is a technology that uses superabsorbent resin to put the roots of the seedlings, and the superabsorbent resin will absorb water to the roots of the seedlings. The roots of the plants absorb water, causing the saplings to die and the soil to compact

Another method is the drip irrigation technology, which has a better effect, but this method has a fatal shortcoming that the effective utilization rate of water is only 15% to 20%, and most of the water is evaporated.

At the same time, this method also has a large one-time investment cost, cumbersome maintenance and is not suitable for afforestation, because after the forest survives, the roots are connected to the underground water veins, so there is no need to water them.
