Combined water guider and manufacturing method and application method thereof

Abstract

The invention discloses a combined water guider and a manufacturing method and application method of the combined water guider. The combined water guider is composed of an outer barrel and water absorption materials. An inner cavity of the outer barrel is filled with the water absorption materials. The water absorption materials comprise soil particles and super absorbent resin. According to the manufacturing method, the water absorption materials are placed in the outer barrel. According to the application method, a vertical hole is drilled downwards from the bottom of a tree which is dug well to a wet layer, the combined water guider is installed in the vertical hole, a nursery stock is planted and watered one time, and then the planting work is completed; after the water poured for the first time is completely evaporated, as the water absorption materials in the combined water guider are composed of the soil particles of which the granularity is smaller than or equal to 1mm and the super absorbent resin of which the granularity is smaller than or equal to 0.1mm, a thinning effect is achieved, water in the underground wet layer will permeate upwards and ceaselessly to be transmitted to the root of the nursery stock to supply water for the nursery stock, survival of the nursery stock is ensured, and supplement of external water resources is not required.

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 composite water diversion body and its preparation method and application method. Background technique [0002] Land desertification has always been a worldwide problem. As one of the countries most seriously harmed by desertification, China suffers a direct economic loss of 54 billion yuan every year. Desertification also causes frequent sandstorms, which seriously restricts the ecological balance and sustainable development of the environment in the arid regions of western my country. [0003] There is a 0.5-2m thick dry soil layer on the surface of the arid area, the soil has poor water retention capacity, and the surface temperature is high. Using the traditional watering method, the surface water evaporates quickly, which has a negative impact on the survival and growth of the see...

AI Technical Summary

Problems solved by technology

Using traditional watering methods, surface water evaporates quickly, which adversely affects the survival and growth of seedlings in this area, and the survival rate of seedlings is very low.

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.

[0004] The methods currently used for afforestation in arid areas are superabsorbent resin technology, drip / infiltration irrigation technology and solid water technology. Among them, superabsorbent resin has the advantages of fast water absorption rate and strong water retention capacity, but in the case of lack of soil moisture, from The root of the plant absorbs water in reverse, causing sick growth or even death of the plant

Drip / infiltration irrigation technology has controllable water supply speed and can meet the water required for plant growth, but there are problems that the dripper / infiltration irrigation head is easy to block, high cost and serious water waste

Solid water technology releases water gradually for the needs of plant roots through microbial decomposition, but it has the disadvantages of high cost, poor water retention and salt tolerance

[0005] In the patent ZL200510000415.X previously applied by the applicant, the water-absorbing material is a single soil particle, which has a fast water-absorbing rate, but poor water-retaining capacity. After absorbing water, it will shrink and cause the water diversion body to break, affecting its normal use.
