Frequently Asked Questions About Integrated Drip Trickle Irrigation and Fertigation System

Why can drip trickle irrigation save 30%-50% of fertilizer?

Answer: Firstly, using water-fertilizer integration drip trickle irrigation system can easily achieve small amount of multiple fertilization, and fertilization can be performed according to the fertilization requirements of crops. Secondly, it can reduce fertilizer waste caused by volatilization and washing, thus greatly improving fertilizer utilization. Generally, the lower the soil fertility level, the more obvious the effect of fertilizer saving.

Why can drip trickle irrigation save 90% of fertilizer and irrigation labor?

Answer: drip trickle irrigation fertilization and watering do not require digging or covering soil, and it is fast. Thousands of acres of area can complete the irrigation and fertilization tasks in one or two days. drip trickle irrigation fertilization is a facility irrigation and fertilization, and the operation of the entire system only requires one labor force to easily complete the irrigation and fertilization tasks. This is particularly effective in areas where crop planting is concentrated and mountain fruit orchards, which reduces labor.

Drip trickle irrigation drops water one by one, with a very small amount of water. Can it meet the water requirements of crops?

Answer: Yes! In fact, there are many options for drip head flow rates, with a common range of 1.0-10.0 liters/hour. The choice of drip head flow rate is mainly determined by soil texture, and usually the heavier the texture, the smaller the drip head flow rate.

Although the flow rate of each drip head is very small per second, the watering time is long. Taking drip heads with a specification of 2.3 liters/hour as an example, if two drip heads are arranged for each fruit tree and the watering time is 2.5 hours, each fruit tree will receive 11.5 liters of water, and 23 liters of water will be emitted in 5 hours. drip trickle irrigation can increase the water supply by extending the irrigation time and increasing the number of drip heads, which can meet the water requirements of crops in various hot climates.

Which crops are suitable for installing drip trickle irrigation?

Answer: Speaking from a purely technical perspective, all crops can be installed with drip trickle irrigation. Evaluating whether a crop is suitable for drip trickle irrigation is mainly based on economic factors and crop planting methods. Crops that are grown in lines and ridges, potted plants, various crops in mountain regions, economic forests, Chinese herbs, etc. can all use drip trickle irrigation. Currently, the most widely promoted crops are cotton, potatoes, corn, grapes, citrus fruits, bananas, flowers, greenhouse vegetables, sugar beets and other crops.

What are the requirements for water quality for drip trickle irrigation?

Answer: Since the drip head is a precision component, it has certain requirements for the particle size of impurities in irrigation water, and drip trickle irrigation requires a grain size of no more than 120 mesh to ensure that the drip head is not blocked. If the water source filtering measures and equipment meet the requirements, well water, canal water, river water, mountain pond water, etc. can all be used for drip trickle irrigation. Therefore, water source filtration equipment is the core component of drip trickle irrigation systems. Most drip trickle irrigation systems cannot work properly due to inadequate filtering equipment or neglect of filter cleaning.

Can organic fertilizer be used with drip trickle irrigation?

Answer: drip trickle irrigation system is a liquid pressure water delivery system, which obviously cannot directly use solid organic fertilizer. However, we can use the bio-slurry produced by organic fertilizer decomposition, which is filtered after precipitation. Chicken manure, pig manure and other decomposed organic fertilizer can be used after filtering. A three-stage filtration system is used, first filtered with a 20 mesh stainless steel mesh, then with an 80 mesh stainless steel mesh, and finally with a 120 mesh stack filter. Through drip trickle irrigation system, the application of liquid organic fertilizer not only overcomes the disadvantages of using only chemical fertilizer, but also saves labor and fertilizer costs, and significantly improves fertilizer efficiency.

What are the common methods of fertigation through drip trickle irrigation?

Answer: According to the different layout of drip trickle irrigation systems, multiple fertilization methods can be used. Commonly used methods include gravity self-pressure fertilization, pump suction fertilization, pump injection fertilization, side tank fertilization, Wenqiuli fertilization, proportional fertilization, etc. The specific method of fertilization depends on consulting professional personnel or referring to more detailed data.
