Choose strong seedlings Choose good varieties of disease-free seedlings with strong growth and many fibrous roots. Generally, the seedlings must have at least 4 leaves and a stem thickness of about 1 cm. If the seedlings are purchased from a remote place, the large leaves on the periphery of the plant should be cut off during cultivation, leaving only 2 to 3 small leaves in the middle, which can reduce leaf water evaporation and increase survival rate.
Site preparation and fertilization should be carried out about 15 days before strawberry planting. The soil preparation should be carried out by 30-40 cm deep, combined with the plowing and applying 4000 kg of high-quality farm manure per acre, 15 kg of diammonium phosphate, and 10 kg of potassium sulfate. Rake leveling to make a foundation for making borders or ridges. When making a border, the border is 10-20 meters long, 60-70 cm wide, and 10 cm high; when ridged, the ridge width is 50-55 cm, the ridge height is 15 cm, and the ridge width is 20 cm.
Planting time The most suitable temperature for strawberry planting is 15℃～23℃. It should not be planted too early or too late. The soil temperature for planting too early will affect rooting and the survival rate will be low. Experiments have shown that the temperature is around 15°C, and the survival rate is 95%; the seedlings are too small before the winter is planted, and the accumulated nutrients are too little, which affects the yield in the second year.
Planting method The planting direction should pay attention to the arch of the seedling back to the side of the channel, so that the inflorescence is growing in the same position. The planting depth is the key to the survival of transplanting. The planting depth should not be too deep or too shallow. The most suitable transplanting depth is "not burying the heart deep, not showing the roots shallowly".
Management after planting. After planting, the aging leaves and stolons on the plants should be removed in time; second, nitrogen fertilizer should be applied in late September, 15 kg of ammonium nitrate per mu can be applied, and phosphate fertilizer should be applied; third, timely irrigation should be carried out. After irrigating once, it is necessary to cultivate once to keep the soil loose and increase the ground temperature, which is conducive to the rooting of seedlings.
Prevention of diseases and pests During the growth and development of strawberries, gray mold, powdery mildew, leaf spot, and damage from red spiders often occur. For the prevention and control of gray mold, 0.3% lime-sulfur mixture can be sprayed at the initial stage of the disease; when powdery mildew and leaf spot are prevented, 800 times solution of dystrogen or 800 to 1000 times solution of thiophanate methyl can be sprayed; red spiders occur When it is harmful, spray 40% dimethoate 1200 times liquid for prevention.
