At present, strawberries are cultivated in most countries in the world. American strawberry cultivation area 2. 30,000 hectares, with a yield of 56. 70,000 tons, accounting for about 28% of the world's total output, with an average output of 24. 6 tons/hectare. Cultivated area in Japan 1. 1 10000 hm2, yield 2 1. 80,000 tons, accounting for 1 1% of the world total output, with an average output of 19. 3 tons/hectare. Europe is the main strawberry producing area, accounting for about 50% of the world's output. Poland, Italy, Spain, the Netherlands, Belgium, Russia, Romania and Britain have large cultivation areas, and the output is generally 9. 5- 18。 3 tons/hectare.
China is the country with the richest wild strawberry resources in the world, and it has been using wild strawberries for a long time and has been inherited ever since. The cultivation of strawberry with large fruit in China began in 19 15 years, but it was ignored in the past and developed slowly. Strawberry production has developed rapidly since 1980s. At present, the strawberry production area in China is about 70,000 hm2, ranking first in the world. The main producing areas are distributed in eastern coastal areas such as Liaoning, Hebei, Shandong, Jiangsu, Shanghai and Zhejiang, and Sichuan, Anhui, Xinjiang and Beijing have also developed rapidly in recent years. The key strawberry producing areas are Dandong, Liaoning, Baoding, Hebei, Yantai, Shandong, Shanghai suburb, Shuangliu, Sichuan and Lianyungang, Jiangsu, which are suitable for planting in sunny and hydrophobic soil. The soil depth is about 8-10 inch.
For large strawberries, the row spacing should be 12 inch and the spacing between plants should be about 18 inch. It is necessary to remove the vines of the plants in time to facilitate the fruiting of strawberries. Strawberry production is cyclical, so it is best to cultivate some new plants in the first few years of planting.
If you don't like to manage strawberries, you can plant a strawberry every18-24 inches, so that strawberries can grow everywhere. Of course, it will be a bit messy, and the strawberries are not big. If you want to avoid this situation, you can remove some vines properly.
In autumn, plant should be covered with a layer of soil to prevent frost. After the soil is frozen, you can spread 3-4 inches of hay on the plants. In the spring of the following year, when new leaves grow, they are moved to dry grass. When the weather is warm and stable, remove the covering soil on the surface of the plant. But leave some hay between rows to prevent the growth of weeds and keep the soil moisture.
