(1) For selecting strong seedlings, disease-free seedlings with robust growth and many roots should be selected from Baozao Zaosheng, Induka, Gorella and Sofia. General seedlings must have 4 leaves, stem about 1 cm thick. If you purchase seedlings from outside, you should cut out the large leaves outside the plant to leave only 2-3 leaflets in the middle, which can reduce evaporation of leaf water to increase its survival rate. (b) Soil preparation Fertilizer Strawberry roots are relatively shallow, and soils with loose soils, many organic substances, flat terrain, convenient irrigation and drainage, and pH value of 5.5-6.5 should be selected for cultivation. Due to the fact that strawberries have negative resistance, they can also be intercropped or interplanted with tall stalk crops or young fruit trees, making them suitable for garden cultivation. About 15 days before the strawberry planting, it is necessary to conduct site preparation and first spray 200 grams of trifluralin herbicide. Then deep-dip 30-40 cm, combined with high-quality agricultural fertilizer 4000 kg per acre, 15 kg of ammonium phosphate, 10 kg of potassium sulfate. Finally, the soil must be smashed and smoothed to lay the foundation for squatting or fighting. Its length is 10-20 meters, width 60-70 centimeters, and height 10 centimeters. Snoring 50-55 cm wide, 15 cm high, 20 cm wide. (C) Planted in due course The plants are planted in the middle of August and planted in the middle and late August. After the strawberries are planted, they can quickly regenerate and enter normal growth and development. The flat ridge cultivation, planting 2 rows per row, spacing 20 cm, plant spacing 12 cm, planting about 10,000 per acre. Leave a 30 cm aisle between the two temples. When planting, each row is planted with 2 rows, spacing 20 cm, plant spacing 15 cm, and 9000 plants per acre. When planting, it should be noted that it is best to choose to plant seedlings on rainy days or on sunny evenings. To achieve deep planting, do not bury the roots. Shallow cutting does not reveal roots. The roots and necks of seedlings are just flush with the ground. Dig pits before transplanting, then put the seedlings into the pits to make the roots stretch, then fill and water until the seedlings grow new leaves. (IV) Post-planting management In order for the seedlings to grow well after colonization and promote the formation of flower buds, the first one is to remove the aging leaves and stems from the plants in time. The second is to apply one nitrogen fertilizer per acre in late September. After chasing ammonium nitrate 15 kilograms, it can also be used with appropriate phosphate fertilizers. Third, it is necessary to timely watering, and every time after water is poured, it is necessary to cultivate once, in order to keep the soil loose and increase the ground temperature, which will help the seedlings take root. (5) Disease prevention and cure Insect-resistance strawberries often suffer from gray mold, powdery mildew, leaf spot, and spider mite damage during growth and development. To prevent mouldy mildew, it is generally possible to spray 0.3-degree lime sulfur mixture at the early stage of disease; powdery mildew and leaf spot; spray 800-1000 times of Trojan 800-1000 times solution of thiophanate; occurrence of spider mite damage, Spray 40% omethoate cream 1200 times.
