Method for water-saving irrigation and fertilizer application and device thereof

Abstract

The invention discloses a water-saving irrigation and fertilizing method and a device thereof. The method mainly comprises the following steps: digging a plurality of vertical holes in soil around a plant root, then inserting a fertilizer rod made of a fertilizer into each vertical hole, and instilling irrigation water into the fertilizer rod in a stable and small amount manner by a water supply device to cause the irrigation water to be guided into the basement soil via the fertilizer rod and absorbed by the plant root; and adding a water soluble fertilizer as an additional fertilizer to the irrigation water in the water supply device to cause the water soluble fertilizer to go into the soil along with the irrigation water.

Description

technical field [0001] The invention relates to a water-saving irrigation and fertilization method and its device, in particular to a water-saving irrigation and fertilization method and device suitable for desert greening and other occasions where water resources are insufficient. Background technique [0002] Due to the impact of desertification on the earth, urban development, population increase and other factors, the traditional arable land area has decreased, which has prompted agricultural experts to actively develop plants that can be planted in harsh terrains that lack water such as deserts or barren hillsides. technology. How to effectively irrigate and fertilize plants under limited water resources when planting plants in this type of harsh terrain has become the two key factors for the success of greening. [0003] In addition, due to the shortage of water resources and the excessive use of chemical and inorganic fertilizers and pesticides in agriculture in the ...

Problems solved by technology

The underground irrigation method can also achieve excellent irrigation efficiency, but because the water supply pipeline must be buried in the ground, and pressurization equipment such as a hydraulic press is required, the investment cost is the highest, and ordinary farmers cannot invest at all

And during its operation, if the pipeline negative pressure is accidentally generated, the sediment will be sucked into the outlet of the underground pipeline, making the pipeline quite easy to be blocked by sediment, so it is quite easy to fail and difficult to maintain

[0011] Furthermore, as far as the traditional fertilization methods are concerned, in order to increase the yield of agricultural cultivation in the past, a large number of chemical and inorganic fertilizers such as nitrogen fertilizer, phosphorus fertilizer and potassium fertilizer, which can be produced quickly and in large quantities, were used in large quantities. However, the result of long-term use of inorganic fertilizers will make the organic matter in the soil Reduced, resulting in the reduction or extinction of large organisms such as microorganisms or earthworms, resulting in the phenomenon of compaction and compaction of the soil, thus making the downward flow of soil irrigation water slow down more seriously

[0012] At the same time, the traditional fertilization method is to sprinkle fertilizer on the soil surface or bury the fertilizer on the soil surface, but the fertilizer application is limited to the soil surface, so there is also a phenomenon that fertilizer nutrients cannot effectively penetrate into the bottom of the soil produce

Because the growth of plant roots has the characteristics of "water-tropism" and "fertilization-tropism", in the traditional method of fertilizing or irrigating from the soil surface, most of the water and fertilizer are usually concentrated within a depth of about 20 cm deep into the soil , so it is impossible to guide the plant root mass to grow in deeper areas of the soil

In this way, the root system of the plant is superficial, and the root mass of the plant can only absorb the water and nutrients of the relatively superficial soil surface.
