1. In the rainy season, the soil is not short of water. How to fertilize through the drip tape irrigation system?
Fertilization should be carried out as usual when the soil is not devoid of water. Usually after the rain stops or when the soil is slightly dry. Fertilization must be accelerated at this time.
Generally controlled in about 30 minutes to complete. Do not wash the pipe after fertilization, and then wash the pipe after the weather is fine. If the conductivity of the soil solution can be monitored with a conductivity meter, the fertilization time can be precisely controlled to ensure that the fertilizer is not leached.
2. How many years can the drip tape irrigation system generally be used?
drip trickle irrigation pipes are available in a variety of sizes, with wall thicknesses ranging from 0.2mm to 1.2mm. Obviously, the thicker it is, the more resistant it is to mechanical damage. All drip trickle irrigation pipes are added with anti-aging materials. In the absence of mechanical damage, the service life of thick-walled and thin-walled drip trickle irrigation pipes is the same. The short life of many thin-walled flat drip irrigation pipes is mainly due to mechanical damage, resulting in water leakage. From the perspective of mechanical damage, the thicker the drip trickle irrigation pipe, the longer the life. Different crops and cultivation methods have different requirements on the service life.
Generally, crops with high cultivation density (such as strawberries) are more economical and reasonable with a design life of 1 to 3 years, while products with a low cultivation density of fruit trees with a design life of 8 to 10 years are more economical and reasonable. Of course, the service life is long, and the cost of one-time investment will be higher.
3. Why can the special PE pipe for drip trickle irrigation be exposed on the ground?
Because the physical and chemical properties of polyethylene (PE) ingredients are easy to photo-oxidation, thermal oxidation, ozone decomposition, and easy to degrade under the action of ultraviolet rays, ordinary PE pipes are not suitable for use in open fields. Due to the addition of anti-aging agents, the PE pipes for drip trickle irrigation can have a service life of more than 10 years under open ground conditions.
4. Is it necessary to build a reservoir for drip trickle irrigation in mountain orchards?
uncertain. In order to save money, if the terrain height difference of the orchard is within 15 meters, the installation of drip trickle irrigation generally does not need to build a reservoir, as long as the pump with the appropriate head and flow is selected. For terrain with a height difference of more than 25 meters, it is best to build a reservoir at the highest point of the orchard, and use a gravity drip tape irrigation system to save money.
5. Why do drip trickle irrigation projects need a professional team to design and install?
The design of a drip tape irrigation system involves expertise in hydraulics, soil, climate, crop cultivation, and plant nutrition. Usually users themselves do not have so much expertise. It is best to be designed and installed by professionals to ensure correct use and play its advantages.
The professional design and installation team has many years of design experience, and can comprehensively consider various factors. The designed system has certain scalability, and a reasonable design can minimize the cost of future system upgrades and maintenance. At the same time professional companies will provide technical services.
6. How is the price of drip trickle irrigation and fertilization system constituted?
The cost of drip trickle irrigation and fertilization system mainly consists of three parts: design fee, equipment and material fee, and installation fee. The specific price depends on factors such as terrain conditions, height difference, planting density, soil conditions, water source conditions, traffic conditions, drip irrigation head types, type of fertilization equipment, degree of system automation, material model specifications, system service life, technical service level and other factors. Therefore, there is no uniform price for drip tape irrigation systems.
According to the actual situation in China, the current price of drip tape irrigation system varies between 400 and 1,500 yuan per mu. Regardless of the price, its basic functions are the same, i.e. uniform water output and uniform fertilization.
