Basic situation of digital orchard development in Shandong Province

Connotation of digital orchard
Digital orchard can be understood as a modern orchard that takes information as a factor of fruit production and uses technical means such as the Internet of things to visually express, digitally design and manage the information in the whole production process. Its main purpose is to realize the digitization, networking and automation of fruit production. The advanced stage of development is smart orchard. The purpose of the application of orchard digital technology is to reduce production costs, improve resource utilization and improve production efficiency on the premise of improving the output and quality of fruits.
Development status of digital orchard in Shandong Province
In 2021, the orchard area of Shandong Province reached 610600 Hm2, and the output was 19.139 million tons. The average yield per unit area was nearly twice that of the country, and the area and output had been in the forefront of the country for many years. Driven by the demonstration of the provincial modern agricultural development fund (efficient and characteristic agricultural development platform) fruit industry project, the province has developed more than 40000 hm2 of modern dwarf rootstock intensive and efficient cultivation mode orchards, focusing on the promotion of Apple modern dwarf rootstock intensive cultivation mode and supporting technologies such as the Internet of things, integration of water and fertilizer, and green prevention and control of diseases and pests. Among them, the application demonstration garden of Internet of things technology accounts for more than 8.3%, playing a good demonstration and leading role, It can be said that the province has the industrial foundation and advantages to develop digital orchards.
In 2013, Shandong Provincial Department of agriculture and Shandong Provincial Department of Finance issued the implementation opinions on the construction of Shandong Agricultural Internet of things technology application demonstration project. At present, an agricultural Internet of things pattern based on the application of digital technology has been established, which vertically covers agricultural departments and production units at all levels in the province, and horizontally includes planting, animal husbandry, agricultural machinery, circulation, processing, quality and safety of agricultural products. In the field of fruit production, 10 digital and intelligent management demonstration counties such as Qixia, Penglai and Rongcheng have been built. The area of orchards with the application of digital technology is more than 3000hm2. Through the digital Internet of things technology, the environmental conditions of orchards, the growth status of fruit trees and the occurrence of pests and diseases are monitored in real time, and the corresponding management measures are taken in time by using the expert management system to realize automatic and intelligent control.
The digital application of orchards across the province is different. The overall situation is that the eastern traditional fruit production areas are stronger than the central and western regions. The main fruit production areas in Jiaodong have a large number of orchards using digital technology, and the regional digital technology R & D and application services are relatively mature. According to the statistics of the business department, the proportion of orchards using physical sensor equipment such as growth environment and soil physics and chemistry in apple production in Yantai and Weihai is 5%- 7%, and the proportion of orchards using water and fertilizer integration technology is about 20%; Facility orchards are more commonly used in agricultural environment monitoring system, production management control system and video monitoring system.
Main application forms of digital orchard in Shandong Province

IOT production monitoring
The monitoring objects of orchard IOT are mainly meteorological environment, soil moisture and fruit tree growth. On the one hand, meteorological environment monitoring can realize real-time monitoring of orchard lighting, air temperature and humidity, rainfall, wind speed and other data. By setting early warning values, the production indicators can be accurately controlled after the alarm; On the other hand, the system can connect with satellite data to carry out weather forecast in the next 24 hours or 72 hours, give early warning of extreme weather such as late spring cold, hail and heavy rainfall, and remind producers and operators to prepare for disaster prevention and mitigation. In terms of soil moisture, it mainly monitors the soil pH value, dissolved oxygen, water level, temperature and humidity and other data. By setting the early warning value, the system will automatically send out early warning information, so as to achieve the precise control of orchard fertilizer and water. Monitoring the growth of fruit trees, by erecting 720 ° high-definition camera at the appropriate position in the park, we can check the growth of fruit trees in real time, and can automatically turn to emergency video for emergencies. The Yinzi company of Shandong land group has built a 50hm2 high standard modern dwarf rootstock intensive cultivation orchard in Rongcheng City. The base is fully equipped with the Internet of things monitoring system, and has cooperated with Tsinghua Tongfang to develop an intelligent inspection robot system, which realizes the digital monitoring and automatic management of the environmental changes in the whole park and the growth of fruit trees, greatly saving labor costs and improving the utilization rate of resources.

High quality digital orchard in Shandong Province

Constraints on Development
At this stage, the research and application of digital orchards in the province are gradually deepening. The government and large-scale business entities have realized the great benefits of the application of digital technology for improving the fine management of orchards, improving the quality of fruits and marketing management level, and began to invest human, material and financial resources in the construction of digital orchards. However, compared with developed countries such as Europe and the United States, it is still an emerging field and still faces many problems.
The production concept lags behind, and the understanding needs to be improved
Although some large-scale business entities have recognized the development opportunities of digital orchards, the vast majority of fruit farmers who plant small-scale orchards still have insufficient understanding and lagging concepts. They believe that only the input of agricultural materials such as pesticides and fertilizers can bring output and benefits. The automation and intelligent mode of fruit production is still far away from themselves. The input of equipment such as the Internet of things is a waste, and they generally lack a correct understanding of the development of smart orchards.
Lack of technical talents and backward management level
The scientific and cultural quality of fruit farmers is uneven, the overall level is not high, the management ability is low, the ability to accept high-tech is weak, and the understanding and application of information technology is less, which affects the promotion of digital orchard technology. The lack of high-quality technical talents has become the biggest obstacle to the development of smart orchards.
 Imperfect infrastructure and low modernization
The infrastructure construction of orchards in the province is still dominated by traditional water, roads, ditches, etc. there are few carrier and platform infrastructure based on the use of integrated application computer and network, Internet of things technology, mobile terminal technology, 3S (remote sensing technology, geographic information technology, global positioning system) technology, and there is a lack of modern facilities and equipment in the construction of orchards.
Data acquisition is difficult, and the degree of sharing is not enough
There are many factors affecting fruit production, and there are various types of orchard data. The data sources involve many fields, such as meteorology, soil, diseases and pests, growth and outcome, etc. at the same time, affected by collection facilities and equipment, it is difficult to obtain massive data. At present, the collection volume of big data of orchards in the province is still very limited, the collection cost is high, and the sharing level of stock data is low, which is difficult to guide production and operation from the macro level.
The data uniformity is poor, and the accuracy needs to be improved
The data collected by orchard using digital technology includes multiple structural categories such as numerical value, graphics and text, video, etc. there is no consistent data structure, and the uniformity is poor. The process of collecting data is easily affected by the changes of facilities and natural environment, as well as the subjectivity of producers’ business model and planting experience容影响,导致采集数据的精准度不高。果园物联网技术仍处于应用推广阶段,采集数据的方式、方法有待规范,数据精准度有待提高。
