A water and fertilizer integrated device and application technology in hilly and mountainous areas without water sources

Abstract

The invention relates to the field of water and fertilizer integration, specifically a water and fertilizer integration device and application technology in hilly and mountainous areas without water sources. The mechanism is composed of a fertilizer storage pipe (PVC pipe) embedded and installed in rock wool. The rock wool wraps the seepage hole / unit on the fertilizer storage pipe to prevent soil from dripping into the pipe from the seepage hole and blocking the fertilizer storage pipe; The function of the fertilizer storage pipe is to pour soluble fertilizer from the fertilizer inlet when fertilization is required, and then send water into the pipe through the drip pipe, stay for 0.5-1 hour to fully dissolve the fertilizer, and continue to pass the fertilizer liquid from the pipe through the rock. Cotton penetrates into the soil and spreads to the area with dense root system. Another way of fertilization is to add fertilizer to the water storage mechanism to dissolve and mix it, then send it to the PVC pipe without fertilizer through the water delivery system, and infiltrate the soil through rock wool and spread it to the area with dense root system.

Description

technical field [0001] The invention relates to the field of water and fertilizer integration, in particular to a water and fertilizer integration device and application technology for hills and mountains without water sources. Background technique [0002] The integrated water and fertilizer technology integrates irrigation and fertilization, and infiltrates soluble solid (or liquid) fertilizers together with irrigation water to the root system of crops by means of a pressure system or natural terrain drop. It has the advantages of simple operation and small amount of work, reducing the evaporation and loss of water; at the same time, the fertilizer liquid can be transported in a timely and effective manner through irrigation, the fertilizer effect is fast, and the nutrient utilization rate is high; in addition, it can avoid the volatilization caused by the application of fertilizer on the dry topsoil layer. Loss and dissolution are slow, and the final fertilizer effect is ...

AI Technical Summary

Problems solved by technology

However, at present, the infiltration and irrigation integrated water and fertilizer devices are mainly used in plain areas with abundant water sources, while in hilly areas, due to terrain reasons and no fixed water sources on the hillside, it is difficult to lay and use traditional water and fertilizer integrated devices; Once the dripper is clogged, it is not easy to find and repair, and it is easy to affect the normal irrigation and fertilization of the device. However, it is difficult to get in and out of the hilly area, which leads to increased maintenance costs; some equipment built in the early stage was eventually abandoned.
