How to reproduce strawberry seedlings?

How to reproduce strawberry seedlings? Please introduce and guide the propagation of strawberry seedlings with reference to the following planting techniques: first, the soil selection of strawberry is light-loving and shade-tolerant, with shallow roots, not only poor drought resistance, but also high requirements for soil fertility, which is suitable for planting on fertile and well-ventilated sandy loam soil. Second, variety selection the varieties commonly used in Fukang area at present are high quality, high yield, cold resistance, dry heat resistance and drought resistance, such as Dandong Daguo, Ghost Nugan, etc. Third, the seedling breeding adopts the stolon split method, which is simple and easy to operate, and the breeding speed is fast. 4. The seedlings are prepared to be ploughed deeply in the soil half a month before raising seedlings. Every 667 square meters, 3000-4000 kg of rotten organic fertilizer, 10 kg of diammonium and 10 kg of potassium sulfate are applied, and the fertilizer is spread evenly, combined with soil preparation and turned into the soil. Fine soil preparation, make the border according to the topography, the width of the border is 1 to 1.2 meters, and the length varies from place to place, and the seedling area can also be determined according to the number of seedlings needed in the field. 8000 seedlings are used for every 667 square meters in the field, and 150g of trifluralin or Acetochlor is used on the whole field. 40 kg of water is sprayed, and then immediately cultivated land is used for pre-bud weeding. 5. the mother plants were planted in mid-April in spring and mid-August in autumn. The strong seedlings of mother plants with original seed characteristics and free of diseases and insect pests were selected, with the middle of the border as the center, the row spacing was 80cm 100cm, the plant spacing was 30cm, and 1600-2800 plants were planted in 667m2. Through the propagation of stolons, about 40,000 plants can be bred for 2688 square meters of seedlings in the greenhouse. When planting, the stem of the seedling heart should be level with the topsoil, that is, the upper part should not be buried, and the lower root should not be exposed. The same variety should be planted in the same border, and aisles should be left among different varieties to maintain purity. 6. Nursery management 1. Irrigation should be carried out in time after irrigation and planting, and small water should be irrigated every 3 to 4 days in spring planting, and it is best to irrigate once a day or every other day when the temperature is high in autumn planting, and then routine management should be carried out until the seedlings are slowed down and irrigated for 8 to 10 times during the whole growth period. two。 After slow seedling ploughing, combined with irrigation, middle ploughing, weeding and soil moisture conservation should be carried out. The middle ploughing should be shallow, and the root system should not be damaged. During the breeding period, there were 4 times of mid-tillage. 3. Topdressing urea and potassium sulfate twice during the whole growth period, 667 square meters 1015kg, hole application or furrow application, spraying 0.2% 0.3% potassium dihydrogen phosphate or urea twice according to the growth trend. 4. In order to reduce the nutritional consumption, the tidbits extracted from the mother plant should be removed in time, and when the stolon is sent out in large quantities, the newly issued stem should be evenly distributed in each direction of the main stem by artificial soil pressure, so as to promote early rooting. pick the heart in time after the border stem is covered with vines, and remove the excess stolon. Seventh, pest control is easy to induce diseases and insect pests in the summer season of high temperature and humidity. Powdery mildew can be controlled with vermicellin wettable powder or methyl topiramate. Red spiders can be alternately treated with mite or Liuyangmycin. Raise seedlings in spring, raise seedlings in mid-August, raise seedlings in autumn and raise seedlings in April of the following year. The seedlings start in the middle of the year. It is best to transplant seedlings with soil to avoid root injury as far as possible. Cut off the old leaves after raising the seedlings, plant them with them, and do not pull out the seedlings. If transporting or planting seedlings for a while, you can remove 2 old leaves, leave more than 5 cm petiole, keep 2-3 leaves in a cool place or pseudo-planted in sand, do not spray water on the leaves when watering, and provide shade. The seedlings that need to be stored in winter should be bundled into small bundles and stored at 60% humidity and-2: 0 ℃. They should be protected against cold in winter and can be replanted and replanted the following spring. Click to get more strawberry planting techniques click to get more fruit planting techniques
