Development Direction of Water and Fertilizer Integration

From: 本站 Author: admin Posted: 2019-07-12 16:07:32 View: 12

       Water and fertilizer integration technology is a technology that combines fertilization with drip irrigation and synchronously controls water and fertilizer. It uses irrigation facilities to supply the nutrients and water needed by crops with the most precise amount, so as to better save water resources. Therefore, water and fertilizer integration technology will be vigorously supported and promoted by the state, and its development prospects are very broad.

 

(1) Water and fertilizer integration technology is developing in a scientific direction

 

       Water and fertilizer integration technology is developing towards precision agriculture and formula fertilization. Our country has a vast territory, and the level of agricultural production development, soil structure and nutrient status vary greatly in different regions. Therefore, in the process of water and fertilizer integration in future planning and design, before selecting ingredients, soil fertility characteristics and crop fertilizer requirements should be obtained by sampling and testing according to different crop types, crop growth stages and soil types, so that formulation design can be carried out pertinently and appropriate fertilizers can be selected for irrigation. Apply fertilizer.

 

       The integrated technology of water and fertilizer will develop towards informationization. Informatization is the main trend of world economic and social development, and also the key link of industrial optimization and upgrading and industrialization and modernization in China. In terms of water and fertilizer integration, we should not only apply information technology to production, marketing and service processes to reduce service costs, but also increase the development of information technology in crop cultivation. For example, the integrated automatic control system of water and fertilizer can use the geographic humidity sensor to send back the information of soil humidity, so as to obtain the optimal plant water demand by adjusting the amount of irrigation water and the number of irrigation times. In addition, the sensor system can determine the irrigation interval by monitoring the diameter of plant stems and fruits.

 

       In addition, the selection of fertilizers for integrated water and fertilizer technology will also be developed scientifically in the future. According to the characteristics of water-fertilizer integrated irrigation system, special fertilizer for drip irrigation and liquid fertilizer will be selected.

 

(2) Development of water and fertilizer integration technology towards standardization system

 

       At present, the uneven market specifications of water-saving equipment in the market seriously restrict the development of water-saving cause in China. Therefore, in the future development, the compilation of technical standards and management rules for water-saving equipment will continue to form and become industry standards and national standards in order to standardize the production of water-saving equipment and reduce water-saving because of water-saving. Waste caused by non-standard surface of equipment and technical specifications, in order to improve the utilization rate of water-saving equipment. Moreover, standardization of water and fertilizer integration technical specifications will gradually take shape. Current water and fertilizer integration technology, the standard of each fertilization link has not formed a unified, inefficient, so in the future drip irrigation water and fertilizer integration process, equipment selection, equipment installation, cultivation, fertilization, irrigation system and other links should be standardized, in order to form technical standards, improve efficiency.

 

(3) The development of water and fertilizer integration technology towards scale and industrialization

 

       At present, the integrated technology of water and fertilizer has been developed from local experiment and demonstration in the past to extensive application. The radiation range has expanded from North China to the dry and early regions in the Northwest, the cold and temperate regions in the Northeast and the tropical regions in South China. It covers facilities cultivation, soilless cultivation, fruit and tree cultivation, as well as vegetables, flowers, seedlings and cash crops in the field. Cultivation patterns and crops.

 

       In addition, the development direction of water and fertilizer integration technology is also reflected in: realizing localization of water-saving equipment and production equipment, reducing the cost of equipment; solving the problem of recycling and reusing waste water-saving equipment, further reducing costs; developing new water-saving equipment with practicability, popularization and low-cost "two-one-low" plastic water-saving device. Material; Improve the technology promotion service system.

 

       For a long time to come, the market potential of water and fertilizer integration technology in China will be mainly manifested in the following aspects: establishing modern agricultural demonstration zones, introducing advanced water and fertilizer integration technology and equipment as production demonstration by government investment, and letting farmers follow suit: the rise of leisure agriculture, sightseeing orchards and other urban agriculture will be further brought along. Application and development of dynamic water and fertilizer integration technology; investment in agriculture, large-scale production, establishment of special agricultural products bases, development of export trade, agricultural products processing or catering services in cities; improvement of urban environment, development of lawn green in parks, sports fields and residential areas are also potential equipment for water and fertilizer integration. Market; Increase in farmers'income and technical training in place, so that farmers have the ability and willingness to use irrigation and fertilization technology and equipment, in order to save water, soil and labor resources, to obtain the greatest agricultural economic benefits.
