1 The selected area of ​​F1 seedling field should be better than unfertilized strawberry, solanaceous crops, and slightly acidic lands that have good water retention, good fertility conservation, convenient irrigation and irrigation, and high soil fertility.
2 Prepare 2000-3000 kilograms of high-quality rotten farmyard fertilizer before planting and soil preparation, and add 3% per mu to 3 kg per mu, and mix it with the farmyard fertilizer, spread the plow to the tillage layer and control the underground. Insect pests, after the ploughing, made a 2.3-meter double-twisted hoe, a single rake of 1 meter, leaving a 30-centimeter aisle in the middle, with a groove width of 30 centimeters.
3 The colonization time from late March to mid-April will be planted. If the planting is too late, the number of plants will be reduced, and each line will be planted. Before colonization, 75% chlorothalonil 600-800 times spray was used to prevent disease once, and the old leaves and inflorescences were removed, and three compound leaves were retained. The soil was planted as far as possible to prevent root damage. The depth of planting is based on the level of the base of the leaf and the surface of the soil, so that it is not buried in the depths, and the roots are not rooted.
4 Density of colonization Every colony is planted in rows of 800-1000 plants per mu.
5 Planting Field Management
5.1 Enhanced fertilizer management After planting, the rooting water shall be poured and the water shall be continuously 2-3 times to keep it moist and conducive to survival. In the rainy season, pay attention to drainage. After planting and survival, 5 kg of urea per acre is used to raise the seedlings, enter the vigorous growth period (occurrence period of the stems), and top-up compound fertilizer is applied 1-2 times. The dosage per acre is controlled at 5-8 kg, avoiding high nitrogen. .
5.2 Removal of Inflorescences, Old Leaves, and Diseased Leaves After the strawberry seedlings are planted, the flower buds on the mother plants are often removed to concentrate the nutrients, and the vegetative growth of the mother plants and the growth of the stolons are promoted. And often remove the old leaves, diseased leaves, conducive to plant ventilation, light transmission, and promote healthy growth of mother and seedlings.
5.3 Stem harvesting After planting the mother plants, they should always be inspected in the field and keep the stems at a certain distance. When a large number of stolons occur, the stolons that are close to each other are spread to make them evenly distributed, and the crosses or overlaps are prevented and controlled. At the same time, in order to make the adventitious roots on the stolon nodes penetrate into the soil in time, the adventitious rhizome segments that occur on the stolons are pressed and stabilized with soil. .
5.4 Cultivated and weeding strawberries are more sensitive to herbicides. Use herbicides with caution. Under normal circumstances, manual weeding is safe. Before planting the mother plant to the stolon, the soil is easy to compact due to frequent irrigation, and the crop should be removed by cultivating loose soil and easy to take root. The occurrence of stolons is caused by the rain and the overgrown season, and weeds are often removed.
5.5 Pest control The common pests of strawberry propagation seedlings are mainly cockroaches, aphids, and Spodoptera litura. Diseases mainly include snake eye disease and anthrax. Use a 1000-fold dilution of 90-fold crystals of trichlorfon 1000-fold or 50-fold of phoxim-emulsion 1000 times. The aphids and Spodoptera litura were sprayed with 1000-1500-fold imidacloprid or 1.8% avermectin emulsifiable concentrate 3000 times. Anthracnose, snake eye disease with 70 thiophanate-methyl WP 1000 times or 75 chlorothalonil WP 800 times alternating use, every 5-7 days spray once, spray 3-4 times.
