What is the distribution of strawberries? What is the benefit of planting one mu?

Strawberry is a kind of fruit with unique appearance and many varieties. It tastes soft and waxy and is deeply loved by consumers. Strawberries are planted in many places, so what is the distribution of strawberries? What is the benefit of planting one mu?

What are the producing areas and distribution of strawberries?

There are 200-300 new varieties cultivated by China itself and introduced from abroad. There are 13 major strawberry producing areas in China, namely, Dandong of Liaoning, Fengxian and Fuyang of Anhui Province, Baoding of Hebei Province, Yantai of Shandong Province, Weifang and Linyi. In addition, the planting scale of Changping in Beijing, Donggang and Xuzhou in Jiangsu, around Shanghai, Huangpi in Hubei and Jiande in Zhejiang are all over 10000 mu.

What is the benefit of planting one mu of strawberries?

The cost composition of planting one mu of strawberries includes: land rent, seedling fees, chemical fertilizers, pesticides, labor and other costs. The cost of planting one mu of strawberries is about 8000-10000 yuan. If we use greenhouse or greenhouse planting, we need to increase the investment of 4000-5000 yuan per mu. Under the normal planting management, 8000 strawberry seedlings are planted per mu, and about 5000 jin of strawberries can be harvested per mu. The average price of strawberries in the market is 10 yuan per jin, and the output value per mu is about 40,000 yuan. In addition to the planting cost, the income per mu is about 3-35000 yuan. But this is only the theoretical planting benefit, because the output and cost are uncertain factors, and the specific input and output need to be determined according to the actual situation.

3. Main points of planting strawberries in greenhouse

1. Timely buckle the shed for heat preservation

In general, when the temperature drops below 5 ℃, the strawberry cultivation bed should be covered with a small semicircular arch shed and covered with colorless plastic film. Pay attention to ventilation in the initial stage of buckling shed to prevent more than 30 ℃ in the shed, especially around noon when there are no clouds and strong sunlight in sunny days, and high temperature burning seedlings should be prevented. In addition, when the lowest temperature in the greenhouse is about 5 ℃, cover the greenhouse film with paper quilt or grass to keep warm at night, and remove it in time after sunrise during the day, so as to increase daylight exposure, increase the temperature in the greenhouse, and beware of freezing injury or retting roots. Enter a few cold days, if the highest temperature in the shed is below 10 ℃, do not take off the covered thermal insulation material during the day to facilitate strawberries to survive the winter safely. After the "May 9" and "69" days, when the external temperature is stable above 0 ℃, the paper quilt or grass quilt can be removed after sunrise during the day, but it should be covered in time before sunset in the evening to maintain a higher temperature in the arch shed. When the temperature in the small arch shed is stable above 5 ℃ at night, the cover can be removed, weather changes can be paid attention to at any time, and timely ventilation can prevent the harm of high temperature.

2. Strengthen the management of fertilizer and water

The fruiting period of strawberry in greenhouse is long, so it is necessary to apply reasonable topdressing on the basis of re-application of base fertilizer in order to meet its nutritional requirements. Topdressing takes the principle of "a small amount and many times". From buckling shed to budding, shallow water can be applied once in about 10 days, 10 kg of urea per mu, 5-8 kg of calcium superphosphate and potassium chloride each. In addition, in the middle and later stage, it can be combined with spraying, foliar spraying multi-element micro-fertilizer or phytin and other organic nutrient solution to improve the fruit weight and sugar content of strawberry. The temperature in the greenhouse is too high and the soil water evaporation is large, so it should be irrigated in time. In the early stage, the external temperature was high, and irrigation was carried out in the evening; in the later stage, the temperature inside and outside the greenhouse was lower, and irrigation was carried out in the morning. After irrigation, first increase the temperature of the shed, and then increase the air volume and reduce the humidity. Don't water too often and water thoroughly every time. Stop watering one week before flowering, and water once 15 days after flowering combined with fertilization.
