According to statistics from the Food and Agriculture Organization of the United Nations, 75 countries in the world produce pears. In 2003, the total area of ??pear in the world was 1.6596 million hectares and the total output was 17.1912 million tons, while the total area of ??Chinese pears was 1.1085 million hectares and the total output was 9.223 million tons, accounting for 66.79% and 54.8% of the world's total pear area and total output respectively. . In terms of per capita pear fruit possession, in 2003, the world's per capita pear fruit volume was approximately 2.76 kilograms, and the average per capita pear fruit volume was 6.98 kilograms, which is higher than the world's per capita level of 2.76 kilograms, but far lower than the 16 kilograms per capita level in Belgium, Italy and other countries. In 2002, the world's annual pear trade volume was approximately 3.482 million tons, with a trade volume of approximately US$2.134 billion, accounting for 20% of the world's total production. Among them, Europe's trade volume was 1.7436 million tons, accounting for 51% of Europe's total production, and Asia's trade volume was 1.7436 million tons, accounting for 51% of Europe's total production. is 5%. The trade volume of Chinese pears only accounts for 2.68% of the total production, which is far lower than the world's average pear trade volume.

In recent years, pear prices in the international market have basically remained stable. Compared with 1992, in 2002, the export price of pears from Belgium, Italy and Germany in Europe dropped to a stable range of 0.8 to 1.1 US dollars/kg. However, the export price of Japanese pears is US$2.36/kg, while the export price of Chinese pears is US$0.24/kg. Currently, 20% to 30% of pears in developed countries are imported. The demand for fresh pears in the European market alone is growing at a rate of 5% every year, and because the price of pear fruits in my country is far lower than the price in the international market, it has created market space for the export of pear fruits in my country.

In pear production, all parts of the world are developing in the direction of early fruiting, high yield, high quality, dwarfing and dense planting, improved varieties, mechanization, and intensification, and are emphasizing regionalization and standardization to make full use of natural resources. and economic resources, give full play to variety advantages, and form an industrialized business model with high yield, high quality and low cost.

Pear dwarf cultivation is developing rapidly in European and American countries, with France being the earliest and Germany the fastest. All are now under dwarf cultivation. The United States, Italy, the United Kingdom, Poland, Denmark and other countries are all developing. The most widely used dwarf rootstocks at present are EMA, EMC and EMH. In the United States, dwarf and semi-dwarf rootstocks such as F9, f51, f333, F267, and F217 are the most widely used.

In terms of plastic pruning, Japan, South Korea and other Asian countries mostly use horizontal scaffolding cultivation methods for pear trees. This can not only effectively resist typhoons, but also facilitate fruit bagging, weeding, etc. manage. In most European and American countries, hedge-shaped and hedge-shaped trees are mainly used, and some adopt cluster-like spindle-shaped and modified cup-shaped trees. The density is generally 630 to 1500 plants per hectare. Hedge-shaped yields are higher, with the highest yield in Italy reaching 7133 kg per 667 m2 in 1969.

In terms of fertilization, all countries determine the type and amount of fertilizer based on leaf analysis and soil analysis. It is generally believed that the leaves of high-yielding pear trees contain 2.0% to 2.5% nitrogen, 0.15% to 0.3% phosphorus, and 1.2% to 1.6% potassium. Based on pre- and post-natal leaf analysis and soil analysis of pear trees, Japan produces formula fertilizers that meet the needs of various varieties based on the fruit production of a tree and the amount of nitrogen, phosphorus, and potassium consumed from the soil. Make pear tree fertilization more scientific and reasonable.

The application of growth regulators has promoted the development of pear tree production. It is mainly used to thin flowers and fruits, increase fruit set, inhibit growth, promote flower bud differentiation and fruit ripening. French researchers extracted sap from the trunk of the pear tree one week before budding, analyzed its nitrogen, phosphorus, potassium, calcium and carbohydrate content, and proposed that this should be used as the basis for pruning and thinning flowers and fruits.

The rapid development of controlled atmosphere storage has extended the storage time of fruits, achieved seasonal production and annual sales, and changed the combination of varieties, from a large number of varieties to a small number of excellent varieties. Currently, issues such as the harvesting time of high-quality fruits suitable for storage, automatic adjustment of gas components during controlled atmosphere storage, and ensuring the quality of fruits during long-term storage are being studied.
