Management Measures of Strawberry Flour Seedling Field
1. Strengthen fertilizer and water management After planting, it is necessary to irrigate the rooting water, and continuously water 2-3 times to keep it moist, which will help to survive, enter the rainy season, and 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. .
2. After removal of inflorescences, old leaves, and diseased leaves of strawberry seedlings, the flower buds on the mother plants are often removed to concentrate the nutrients and promote the vegetative growth of the mother plants and the extraction of the stolons. And often remove the old leaves, diseased leaves, conducive to plant ventilation, light transmission, and promote healthy growth of mother and seedlings.
3. After planting the stems and stems, the mother plants should be checked frequently in the field, and the stem stems should be kept 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. .
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, pest control
The common pests of strawberry propagation seedlings are maggots, 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.
