Advantages and disadvantages of integrated water and fertilizer technology
The integration of water and fertilizer is also called irrigation and fertilizer or "water and fertilizer coupling". It is a new technology developed with the help of water and fertilizer integration equipment ( Water fertilizer machine). Its process is: fertilizer → dissolution → pressurization → transportation → irrigation. The pressure system of the integrated water and fertilizer equipment mixes soluble solid fertilizer or liquid fertilizer into fertilizer solution according to requirements. After pressure, it can be transported to the roots of fruit trees through the pipeline system together with irrigation water. The fertilizer can be completed according to the agricultural IoT sensor and intelligent control system. Precise and controllable, punctual and quantitative moisturizes the root spread area.
Application and composition of water and fertilizer integration:
According to the agricultural Internet of Things technology, remote sensing technology, geographic information system and global positioning system, the water and fertilizer integration technology is widely used in the irrigation of farmland and orchards at home and abroad. Including water pumps, power units, filters, fertilizer injection equipment, measuring and controlling appearance, etc.), water delivery and distribution pipelines, and drippers.
Advantages of water and fertilizer integration:
The water and fertilizer integrated equipment can dissolve the water and fertilizer and transport it to the vicinity of the main trunk of the fruit tree through the water pipeline, and the dripper or sprinkler slowly releases the water and fertilizer to soak the adjacent soil of the root system. The advantages of the integrated water and fertilizer technology are the simultaneous application of water and fertilizer, which has fast fertilizer efficiency and high nutrient utilization. It can prevent the volatilization loss and slow dissolution of fertilizers caused by the application of fertilizer in drier soil. It saves fertilizer and reduces environmental pollution. Save labor and time.
Disadvantages of water and fertilizer integration:
The disadvantage of the integration of water and fertilizer <http://jxctdz.cn> is that one-time investment is large, drip irrigation equipment is easy to be blocked and damaged. Long-term implementation of water-fertilizer integration can easily constitute the root zone and cause root suffocation. Many water-soluble fertilizers are There is also the risk of secondary salinization when used. There are no links such as soil loosening, weeding, and root cutting. If the time is too long, it will cause soil compaction, which will affect the root development of fruit trees and fruit quality.
