Application effect of fruit bagging

Pest control effect is remarkable

Today, with the continuous development of tropical and subtropical fruit planting, the application area of ​​fruit bagging technology is also expanding, and the effect of pest control is remarkable. According to the investigation of 4 demonstration sites for comprehensive control of fruit tree diseases and insect pests carried out by Guangzhou Fruit Tree Science Research Institute and Guangzhou Agricultural Environment and Plant Protection Station, the application area of ​​fruit bagging is more than 680 mu, and the comprehensive effect of various fruit tree bagging to control diseases and insect pests is average. reached 81.1%. The main fruit trees such as New Century Guava, Mango, Carambola, AP Sweet Apple and other pests are particularly effective in controlling pests, with an average of 90% and 76.7% of diseases.

Economic benefits

Comparing orchards with fruit bagging and conventional pest control and disease prevention management without bagging, even if the yield is the same, the good fruit rate of bagged fruit reaches 90%, while the good fruit rate of conventionally managed fruit is generally only 70%. %. At the same time, because bagging obviously improves the appearance quality of the fruit, the selling price of the fruit in the production area can be increased by 0.5-1 yuan per kilogram compared with the unbagged fruit, and it can be storable. Based on the yield of 2000 kilograms per mu, the two cultivation methods, after deducting the cost of paper bags, bagging labor, insecticide and disease prevention drugs, labor and other labor costs, can significantly increase the yield and output value of bagging by 22%-30% compared with no bagging. %.

Significant ecological benefits

In orchards that apply bagging technology, pesticides are generally only applied during the flowering period and before the fruiting, and the frequency and quantity of pesticides are reduced compared with those without bagging, which can protect the environment, prevent pesticide pollution, and maintain ecological balance.

The promotion of fruit bagging has brought great economic benefits to fruit farmers. According to comprehensive statistics, each set of apples can be sold for 5 cents more, and one apple can earn a net profit of 3 to 4 cents. One mu of land can be calculated as 10,000 apples, which can increase the income of fruit farmers by 3,000 to 4,000 yuan. Therefore, fruit bagging has also expanded from the original Shandong to Shaanxi, Shanxi, Hebei and many southern provinces. But compared with advanced countries, there is still a big gap. Taking apples as an example, there are currently only 3 billion bags in my country, or 900,000 tons in terms of 1 piece and 6 pieces. In contrast, the total output of apples in my country is 21 million tons, and the proportion of bagging is only 4.3%. Therefore, the Ministry of Agriculture has vigorously promoted fruit bagging as an important technical measure in order to further expand the area of ​​bagging. In addition, there are still some related links to be solved in the promotion of fruit bagging technology. One is the promotion of flower and fruit thinning technology. The second is the further development of the bagging paper industry. At present, the performance of bagging paper in Japan, South Korea and Taiwan is better than that of domestic products. Apples are basically foreign bags, pears are mainly domestic bags, and grapes and mangoes are also mainly imported bags. Therefore, it is necessary to actively introduce foreign bags. The advanced technicians, produce qualified and high-grade bagging, cultivate domestic bagging paper production enterprises, and at the same time appropriately reduce or exempt some import tariffs on bagging paper, in order to facilitate the popularization of bagging techniques, and to benefit my country's fruit production capacity. More access to international markets and more economic benefits for fruit farmers and for our country.
