planting strawberry

1. The first step is to accelerate germination. Generally, strawberry seeds can be stored for about 2 years at room temperature. In order to improve the germination rate of seeds, the seeds can be wrapped in gauze before sowing, soaked in gauze for 24 hours, and subjected to low temperature treatment at 0℃～3℃ for about 15 days in the refrigerator to break the dormancy of the seeds, and then sow the seeds to obtain the germination rate. Higher. If you are impatient, you can directly use the following method to germinate the seeds without freezing. However, if the dormancy is not broken by low temperature, the germination rate may decrease.

The method is as follows: first pour the seeds into 50～60℃ warm water to soak, stirring constantly, until the water temperature drops to about 25℃ to stop. After soaking for 2 to 3 hours, remove and rub gently with your hands until the seed coat is clean and shiny. Then rinse it with clean water and cover it with several layers of wet gauze. (This is because when the strawberry is being seeded, there is strawberry acid on it, so this must be washed off.) Place it at 25-30°C for germinating germination. Soak the gauze with warm water three times a day (morning, lunch, and evening) to keep the seeds moist. Sowing after 60 to 70% of the seeds are white.

2. Next, we also need to prepare the cultivation soil for planting strawberries. Strawberries like fertile soil and cannot tolerate barrenness, so it is best to use black or brown soil to grow strawberries. Choose a flat ground, convenient irrigation and drainage, good sunlight, rich organic matter, strong water retention, and good air permeability. If it is a potted plant, a ceramic pot with a diameter of 20-30 cm is appropriate. Use soil with a higher humus content for pot soil.

3. Management, water permeable once after planting, water once in the morning and evening within a week after planting, apply adequate fertilizer from planting to flowering, apply 10 kg of diammonium phosphate during fruit expansion and harvest period, and combine with watering If the growth is good, you can spray 0.1~0.2% potassium dihydrogen phosphate 2~3 times to achieve high yield.

4. Fertilization as a border: fertilize the whole plot in August, apply enough fertilizer, and use organic fertilizer not less than 2000kg per mu, and add a certain amount of potassium and phosphate fertilizer. Cultivation: use furrow cultivation. The height of the ridge is 20-30 cm, the width of the ridge surface is 40-60 cm, and the width of the furrow is 30 cm. The advantages of this are good ventilation and increased soil temperature, which facilitates the growth of strawberries, and use mulching film to increase the required temperature. High-ridge cultivation, the fruit is on both sides of the ditch, sufficient light, good color, and the fruit is not easy to spoil

5. Transplanting time, about the beginning of autumn, when the temperature is about 15℃, the survival rate can reach 95%, when the temperature is 25℃, the survival rate is about 50%, and when the temperature is 30℃, the survival rate is about 10%. 15-25℃ is appropriate, and it should be carried out on a cloudy day. If transplanting on a sunny day, a shed should be built to shade.

6. Flowering and fruiting: The inflorescence of strawberry is cyme, the inflorescence has top inflorescence and axillary inflorescence, and there are about 2-8 inflorescences per plant. The flower is a complete flower, consisting of a flower stalk, a receptacle, sepal sepals, petals, stamens and pistils. In the open field, after overwintering, the flowers begin to bloom when the average daily temperature reaches 10°C or more. One strawberry flower can bloom for 3-4 days, and the pistil can be fertilized within 7-8 days after flowering.

7. Prevention and control of pests and diseases: Strawberries are prone to gray mold in low temperature and rainy weather. It can be used to prevent and cure by adding eugenol carvacrol and Naipu 9, or using Zhuanshijia Luheng No. 8 plus Niu Extract Calcium Boron, or using Kaiser plus eugenol carvacrol and spray-resistant. Mildew fumigant for prevention and treatment; for powdery mildew, use pyridoxine sulfonate plus eucarvacrol plus Lifengan, or use Seize plus Lvheng No. 8 plus Trimble, or use Star Bloom plus eugenol plus eucarvacrol plus Trimble control. In addition, it is necessary to control aphids in time, you can use Shi Dingkang spray to control.

Pastoral management

1. Top dressing: Grasp the principle of applying thin fertilizers and diligently. After planting live trees, apply Havitone. After harvesting about 20 days after harvesting, apply the fertilizer again. You can use Haweiguo or Lifengan root according to the specific situation. Topdressing outside.

2. Watering: Strawberries need a lot of water during the fruit period. It is recommended to use the drip irrigation method for watering to keep the soil above 7~8cm moist.

3. Artificial pollination: During the period of strawberry blooming, use a brush to paint the flowers or spray the whole tree and fruit of Duo Lejia from 8 to 9 o'clock in the morning every day, which can significantly increase the yield of strawberries. It is best to fill the honey in the shed to complete the pollination.

4. Light: In winter, set a 60-watt light bulb every 1.5 meters in the shed for heating and supplementing light, so that the lowest temperature in the shed can be kept at about 5°C, and the harvesting period can be advanced two times. About ten days.

5. Shed shed time: During the shed shed period, when the outside night temperature is 8-10 degrees Celsius, if the temperature is lower than 5 degrees, the dormant period of strawberries will be too long.
