Strawberry planting technique

Strawberry, also known as raspberry, raspberry, raspberry and so on, is a kind of red flower and fruit. Strawberry is a general name for strawberry plants of Rosaceae, which belongs to perennial herbs. Strawberries have a heart-shaped appearance, delicious red and tender, succulent flesh and a special rich fruit aroma. Strawberries have high nutritional value and are rich in vitamin C, which can help digestion. At the same time, strawberries can also strengthen gums, refresh breath and moisturize throat. People's anger tends to be exuberant in spring, and eating some strawberries can inhibit it.

In addition, strawberries had better be eaten after meals, because they contain a lot of pectin and cellulose, which can promote gastrointestinal peristalsis, help digestion, improve constipation, and prevent hemorrhoids and bowel cancer. The nutritional ratio of strawberries is very reasonable, in which the content of vitamin C is about 10 times that of the same amount of watermelons, grapes or apples. In addition, strawberries are rich in iron, fructose, glucose, citric acid, malic acid and so on. For lung heat cough, sore throat and long fire boils that are easy to appear in spring, the nutrient elements contained in strawberries can play an auxiliary role. At the same time, because of iron, anemic friends can also eat often. But doctors also suggest that although strawberries are good appetizers, they are cold, so don't eat too much at one time in early spring, especially for people with spleen and stomach deficiency and cold, diarrhea and excessive stomach acid.

General situation of production and cultivation

Strawberries are cultivated in most countries in the world at present. Strawberry cultivation in the United States covers an area of 23000 hectares, with a yield of 567000 tons, accounting for about 28 percent of the world's total output, with an average yield of 24.6 tons per hectare. Japan has a cultivated area of 11000 hm2, with a yield of 218000 tons, accounting for 11% of the world's total output, with an average yield of 19.3 tons per hectare. Europe is the main producer of strawberries, accounting for about 50% of the world's production. Poland, Italy, Spain, the Netherlands, Belgium, Russia, Romania and the United Kingdom have a large cultivated area, with a yield of 9.5-18.3 tons per hectare. China is the country with the most abundant wild strawberry resources in the world. It began to use wild strawberries a long time ago and has been following it until now. The cultivation of large fruit strawberry in China began in 1915, but it was neglected and developed slowly in the past. Strawberry production has developed rapidly since the 1980s. At present, the area of strawberry production in China is about 70, 000 hm2, ranking first in the world. The main producing areas are located in the eastern coastal areas such as Anhui, Liaoning, Hebei, Shandong, Jiangsu, Shanghai and Zhejiang. In recent years, Sichuan, Anhui, * *, Beijing and other regions have also developed rapidly. Key strawberry producing areas are Jiangsu Sihong, Anhui Hefei, Liaoning Dandong, Hebei Baoding, Shandong Yantai, Shanghai suburbs, Sichuan Shuangliu, Jiangsu Lianyungang and so on. Changfeng County, Hefei currently has 145000 mu of strawberry planting area, with an annual output of more than 200000 tons of strawberries, with a total output value of more than 1 billion yuan, expanding to more than 200000 mu by 2012, and building the only national virus-free strawberry science and technology park in the country. Every year, promotion meetings are held in the Great Hall of the people in Beijing and the Diaoyutai State Guesthouse in Beijing, and dealers and strawberry households are held in Beijing Xinfadi Market, Tianjin Red Flag Market and Shenyang Fruit Wholesale Market. Its production scale has jumped from the top of Anhui Province to the largest county of strawberries in the country, and Changfeng Strawberry has become a well-known trademark in China.

Growth condition

Strawberries are suitable for growing in sunny, hydrophobic soil. The depth of the soil is about 8 mi 10 inches. For large strawberries, the row spacing should be 12 inches and the plant spacing should be about 18 inches. The vines of the plant should be removed in time to facilitate the fruit of strawberries. The yield of strawberries is periodic, so it is best to cultivate some new plants in the first few years of planting. If you don't like managing strawberries, you can plant strawberries every 18mur24 inches so that strawberries can grow everywhere. Of course, it will look a little messy, and the strawberries are not big. If you want to avoid this situation, you can remove some vines properly. In autumn, cover the plant with a layer of soil to prevent frost. After the soil is frozen, the plant can be covered with hay 4 inches thick. In the spring of the following year, when new leaves grow, the hay is removed. After the weather becomes warm and stable, the covered soil on the surface of the plant is removed. But leave some hay between the rows to prevent the growth of weeds and retain moisture in the soil.

Planting technology

Strawberry ranks first in the production of small berries in the world. Strawberry is an economic crop with quick fruit, early maturity, easy reproduction, short cycle and high benefit.

1. Preparation of breeding grounds

1) choose paddy fields with convenient drainage and irrigation, which are not easy to accumulate water and have high fertility, or vegetable garden soil (former crops and soil blocks that have used Lvhuanglong herbicide). Apply sufficient basic fertilizer (cake fertilizer, household fertilizer, human feces and urine, phosphate fertilizer) after ripening, at the same time, use 50% phoxim or 3% furan per mu, mix 25 jin of fine soil, and turn the soil to make a bed. The bed is 1.5 mi 1.8 meters wide and the turtle's back is shaped to prevent stagnant water and the soil should be broken.
