"Seven magenta" No. 4 strawberries were introduced from France by the Qingyuan County Agriculture and Forestry Bureau of Hebei Province. The variety has strong growth potential, high yield performance, high temperature, early maturity, low temperature requirement, high resistance to powdery mildew, and high propagation coefficient. It is suitable for the cultivation of sunlight greenhouses in northern regions. Generally, the output of winter greenhouses can reach 3,500 kg per 667 square meters, and the income can reach more than 10,000 yuan. "Seven magenta" No.4 strawberry has vertical petiole, dark green leaves, large and thick leaves, and elliptical; strong ability to sow stems; low inflorescence branches; short cones, uniform and neat fruit surfaces, Shiny and bright, fruit flesh is fine, orange, slightly hollow, fragrant, sweet and sour palatability, soluble solids content of 12.3%; seeds yellow, uniform distribution, deep embedded; fruit hardness, storage and transportation, the greenhouse promote cultivation techniques as follows. 1, choose the land to build a garden, give enough base fertilizer, deep plowing soil preparation. Select a sandy loam soil with a soil containing 2% or more of organic matter and convenient irrigation and drainage to establish a strawberry garden. Combined with site preparation, 5 cubic meters of ripe organic fertilizer is applied per 667 square meters (when organic fertilizer is used, a layer of wheat straw and a layer of chicken manure and cow dung can be mixed together), and 75 kg of strawberry fertilizer is used as the base fertilizer. Deep plowing more than 25cm, then flattened. 2, choose virus-free strong seedlings, ridge cultivation, reasonable close planting. Virus-free and strong seedlings are selected to require no pests and diseases. Short stems are more than 1cm thick, 4-6 leafy leaves, full heart buds, dark green leaves, root weight occupies more than 1/3 of the total plant weight, and fresh seedlings weigh about 35g. . Ridge cultivation is generally used, ridge height 20-25cm, double rows per ridge, ridge south-south, ridge center distance of 90cm, ridge uphill distance 30cm, plant spacing 15-20cm, 8,000-10,000 plants per 667 square meters planted. The time of colonization was in Baoding area in mid-August, and it could not be later than September 5. 3, timely insulation shed, strengthen management. When the night temperature falls to 8 °C, generally in mid-November, it is necessary to timely cover the insulation of the shed film. In the late November, cover the straw and cricket insulation at night, and the “Seven magenta” strawberries need a higher night temperature, which cannot be lower than 6°C. Otherwise it will affect the normal flowering results. In the severe winter season, it is necessary to adopt double-layer cover grass, double-layer greenhouse film, polyvinyl chloride film for sheds, small sheds built in sheds, raw fire heat-up, incandescent lights and other measures to warm up the light, Ensure the need for temperature lighting in strawberries in cultivation. Strawberry seedlings sprayed magnesium-containing foliar fertilizers with fruit surface light. From February to March, when the outside temperature rises, it should be noted that the shelf temperature during the day should be controlled at 25-28°C to prevent high temperature, high humidity, and low temperature and high humidity. During the winter, the bleeder can be used to release the air, and sub-film irrigation is used; , In the north wall and the East Mountain, excavate 15cm in diameter to remove air and cool off. At the same time as fruit thinning, bees or bumblebees must be stocked to assist in pollination and produce more fruit. 4. Gibberellin treatment. "Seven magenta" on the 4th sensitive to gibberellin, when the shed temperature is high, you can not use; if the amount is slightly larger, then the handle is longer, the result is late, the fruit is small, should strictly control the dosage and concentration, the general amount of each strain 5ml , Concentration 5 - 10um, spray in the core of the plant, can be applied once in the early bud. 5, prevention and control of pests and diseases. "Seven magenta" strawberry is resistant to diseases and has strong stress resistance. It focuses on prevention and control of pests and diseases. It focuses on physical control, biological control, cultivating strong seedlings, increasing organic fertilizer, controlling temperature and controlling humidity, and supplementing with pesticides to prevent diseases. The use of chlorothalonil, speed Ke Ling aerosol 10-15 days 1 time. Stop using it 10 days before fruit picking. 6, timely harvest. Strawberries in greenhouses should be harvested when the fruits reach 80% of maturity, and they should be shockproof and breathable during packing and transportation.
