Compared with traditional irrigation methods, drip trickle irrigation with top fertilization technology saves more water. Traditional irrigation methods waste over half of the irrigation water, while sprinkler irrigation has an irrigation coefficient of about 0.75, and drip trickle irrigation has an irrigation coefficient of 0.95, making drip trickle irrigation more water-efficient.
There are two types of top fertilization commonly used in water-saving drip trickle irrigation equipment: proportional top fertilization and quantitative top fertilization. The amount of fertilizer used for irrigation can be quantitatively expressed and accurately applied to crops, reducing fertilizer evaporation loss and nutrient loss.
According to experiments, top fertilization with sprinkler irrigation can save 11% to 10% of fertilizer efficiency, while top fertilization with drip trickle irrigation can save fertilizer efficiency.
The fertilizer can be injected into the top fertilization tank, and then drip trickle irrigation through the irrigation system, drip trickle irrigation pipe, pressure compensation dripper, arrow dripper, dripper hole or flow path, into the soil for irrigation. If a control device is added to the irrigation system, automatic top fertilization can be achieved.
A complete set of drip trickle irrigation and top fertilization systems can operate on several acres of land, ranging from several dozen to several hundred acres in size. Only 2 to 3 workers who have received simple training can complete the top fertilization task in a short time, greatly reducing labor and material expenditures and saving costs.
The economic benefits of increasing production and increasing yield from irrigation and top fertilization include increased production, improved quality, increased income, and reduced costs. Water and fertilizer application can be used for a variety of crops.
Since nutrients in fertilizer are in a dissolved state, they can enter the soil more quickly and be absorbed by the roots and leaves of crops, improving their drought resistance and promoting an increase in yield and quality.
drip trickle irrigation is a technology that uses water at a certain pressure, filtered through a drip trickle irrigation system and drippers, to evenly and slowly drip into the soil near the plants for irrigation.
drip trickle irrigation has advantages such as water saving, uniform irrigation, energy saving, strong soil adaptability, increased yield, labor saving, and convenient field operation, but its main disadvantages are high water consumption, simple clogging, and high requirements for water quality.
It is mainly used for economic crops, such as trees, vegetables, flowers, greenhouse farms, and areas with extremely limited water sources, high-lift water pumping areas, and large-scale irrigation. It also has some development prospects and can be used in sandy soils with strong permeability and poor water retention and in saline-alkali soil areas.
The drip trickle irrigation pipe is formed by the drip head and capillary pipe working together. It can be divided into embedded drip trickle irrigation pipe and thin-walled drip trickle irrigation pipe.
