Apple bagging can not only promote uniform coloring and fruit growth in a short period of time, but also cut off the path of multiple diseases and insect pests directly harming the fruit, effectively reducing the incidence of pests and diseases. Since the 1990s, Shandong has begun to use apple bagging technology, and the apple bagging subsidy implemented by the Ministry of Agriculture has allowed this technology to be widely promoted. In the past, bagging technology, as an important measure to improve the quality of apple fruit, provided the market with high-quality fruits with good color and flavor, which brought great benefits to fruit farmers.
However, time has passed. At that time, this new technology encountered the problem of high labor costs in rural areas, low fruit farmers' benefits, and waste paper bags polluting the environment. At the Apple Non-Bag Watching Meeting held on September 25th, the application of Apple's non-bagging technology in the Kuling Ecological Orchard left a deep impression on the participating apple growers.
Director Wang Kuiliang of Yantai Agricultural Technology Promotion Center said: "In 2015, Shandong apple planting area reached 4.5 million mu, with a total output of 9.6 million tons. Apple bagging technology is almost the main production management technology. Bagging has incurred high cost. It has become a major problem in the development of the fruit industry. According to statistics, the average set of 10,000 bags per mu of land is equivalent to 0.2 yuan for paper bag fees and bagging and bag picking, which accounts for about 1/3 of the total production cost. Shandong has an average of 20-25 billion bags per year, with a total cost of 6.7 billion yuan and a national total of 52.8 billion yuan. The negative effects of energy consumption and environmental pollution caused by paper bags used for bagging are even more difficult to estimate. Since 2015, they have begun to promote apple non-bagging technology in Qixia, Huangdao, Laizhou and other places.
Wang Jingbo, chairman of the Laizhou Xiaolong Farmers Professional Cooperative, said: "From last year, the apples using 'Sail Julie' without bagging technology have good fruit, bright color and consistent appearance and bagging. It has the advantages of fruit rust, anti-bite, good taste, high sugar content, storage resistance, early fruit harvesting, etc. It frees fruit farmers from the troubles of bagging and bag picking, saves labor and cost, and the comprehensive cost is much lower than the original. Bagging technology."
Zhao Zhongzhi, an agricultural expert from Xinyang Group, pointed out that apple bagging has over-emphasized the appearance quality of the fruit. Apples have seriously hindered the injection of sunlight after the paper bag, which affects the photosynthesis. Although the bagging improves the appearance quality of the fruit, at the same time The content of soluble sugar, titratable acid, vitamin C, protein, etc. is reduced, and the flavor is reduced and the taste is lightened. Some developed countries have also experienced the process of bagging and bag picking. At present, apples in Europe, America and Oceania are not bagged, and the bagging rate in Japan is less than 10%. The “Sail Julie†apple bagless planting technology we promoted is a planting technology for a complete plant protection program, 80% in Japan. The above apple plantations are using the "Cyre Julie" technology.
Apple's use of non-bagging technology means no bag pollution, no reflective film pollution, reduced pesticide pollution, significant social benefits for saving wood pulp, preventing acidification of soil and promoting environmental protection. Apple bagging technology is leading apple cultivation. The new trend.
