Four-season strawberry planting method video park site selection and soil preparation Strawberries like light, fertilizer, water and waterlogging. It is advisable to choose plots with high terrain, flat ground, loose geology, fertile soil, suitable acid and alkali and good ventilation to build the park. Special strawberry orchards can be established, and young orchards can also be used for intercropping.
Weeds should be removed before ridge planting to prevent underground pests. Till 30-40 cm, and apply 3000-5000 kg of high-quality organic fertilizer every 666.7 square meters. Open field cultivation mostly adopts flat ridge planting. General ridge width 1.2 1.5m, length 1020m and ridge height 15cm. Most protected areas are planted with high ridges, with the ridge height 1.520cm, the ridge top width of 40.50cm (planted in two rows), the ridge bottom width of 60.70cm, and the ridge width1.520 m. After the ridge is completed, a small amount of water can be poured or appropriately pressed to make the soil sink.
Planting technology: Strawberry planting period: spring planting is generally from mid-late March to early April, and autumn planting is from mid-late August to mid-late June 10.
The planting density is generally 8000 9000 plants /666.7 square meters. Old leaves should be removed before planting, and it is best to transplant them with soil. When planting seedlings, the arched back of new stems should face the same direction of inflorescence growth, and high ridge planting needs inflorescence to face the outside of ridge. The planting depth should make the base of seedling heart flush with the ground, so that the roots are shallow and the heart is not buried deep. Plant spacing can be controlled at 30 cm and 40 cm, and triangular planting is adopted. Irrigation should be done in time after planting.
Fertilizer and water management Because strawberries bloom and bear fruit continuously throughout the year, underground topdressing and foliar spraying are needed many times during the growing season. Underground topdressing is generally 4-6 times a year, and about 50 kilograms of compound fertilizer is applied every 666.7 square meters. Foliage fertilizer is sprayed once every 20 days, and the concentration of 0.2% and 0.3% is the main compound fertilizer. Water it in time after each topdressing. Strawberries are not resistant to waterlogging, so pay attention to drainage in rainy season.
Controlling weeds in the field is an important guarantee for producing high-quality large-fruit strawberries. Weeding in the field can be done by manual weeding, plastic film mulching and grass pressing, and herbicides can also be used. In strawberry growing season, 35% fenpropathrin EC or 10% fenpropathrin EC is generally used to control weeds in the field.
Four-season strawberry can blossom and bear fruit about 60 days after planting. If you want to produce high-quality big fruit, high yield and high efficiency, you must plant strong seedlings and raise them. Especially for the seedlings planted in spring, seedling raising and seedling strengthening should be carried out before fruiting, and attention should be paid to timely removing buds and stolons in the early stage, and flowers and fruits should be left when the crown width of seedlings reaches 30 ~ 40cm. Sowing seedlings in spring, raising them in spring and summer, and bearing fruit in late summer and early autumn can achieve high quality, high yield and high efficiency.
At the flowering stage, 4 5 early flowers and large flowers are reserved at a time, and late flowers and small flowers are excluded. The sooner you spend time, the better. After fruit setting, small fruits and deformed fruits are thinned out, and 3 ~ 4 large fruits can be retained per plant at a time. After the previous fruit ripens, choose 4 ~ 5 large flowers to keep continuous flowering and fruiting.
Removing stolons and old leaves In order to reduce nutrient consumption and ensure high yield and continuous fruit, stolons should be continuously removed during the growing period. Early stolon removal can increase strawberry yield by 20%. During the whole growth period, it is necessary to continuously remove the old leaves at the lower part to promote the growth of the new leaves and stems at the upper part. The time to remove old leaves is generally controlled when the petiole begins to turn yellow and the petiole changes from upright to flat.
Pest control The main disease that harms strawberry fruit is gray mold. Prevention and control measures: First, reasonably close planting, apply less nitrogen fertilizer, avoid flooding, remove diseased plants, diseased leaves and diseased fruits in time, and strengthen ventilation. Followed by chemical control. You can choose 50% botrytis cinerea 1000 times solution, 50% sucralfate 1000 times solution or 50% nongliling 1000 times solution to spray evenly from the inflorescence contact period to the harvest period, and the chemicals are used alternately, every 10 15. It is best to choose a fumigant, fumigant and fumigation at flowering stage. For anthracnose, leaf spot and powdery mildew, 65438 times solution of 70% thiophanate methyl wettable powder and 800 times solution of 75% chlorothalonil wettable powder were used alternately before and after the rainy season.
Strawberries managed in winter can blossom and bear fruit all year round as long as the temperature is suitable. Spring, summer and autumn can be cultivated in the open field. 10 When the temperature drops to 5 7 degrees Celsius in the middle and late June in Henan and Shandong, the shed should be closed in time to ensure continuous flowering and fruiting.
Planting techniques of strawberry in four seasons: site selection and soil preparation
Strawberry orchard should be selected with sufficient sunshine, slightly higher terrain, flat ground, convenient irrigation and drainage, fertile and loose soil, and the previous crops should be beans or onions and garlic vegetables. Weeds and underground pests in the garden should be removed first. Spraying 1000 times of 50% phoxim EC (5-6 cm in wet soil layer) can control grubs, crickets and cutworms.
After 1 week, 5000 kg of high-quality decomposed farmyard manure, 0/00 kg of calcium superphosphate/kloc-0 and 50 kg of potassium chloride were applied to the mu base. Combined with deep ploughing, fine soil preparation was carried out to make the border surface 20 cm high, 50 cm wide and the border ditch 30 cm wide. The length of the greenhouse is limited to 20 meters, and there are 4 beds in it.
Transplanting technique
In order to market strawberries from the end of/kloc-0 to the beginning of February, the time for transplanting strawberry seedlings from breeding nursery to the edge of greenhouse should be in early September. Two rows should be planted in each border, the row spacing is 27 cm, the hole spacing is 20 cm, and each mu 12000 plants. When planting, the inflorescences of plants in the same row face in the same direction, so that the back of strawberry seedlings is arched towards the predetermined growth direction of inflorescences, the seedling center is exposed from the edge, the roots are spread out and buried in the loose soil layer, and planting water is poured in time, and the exposed roots are buried in the soil layer.
