1. Fertilizer management. After wintering cultivation of strawberry greenhouses, the indoor temperature is high and the water evaporates quickly. During this period, the plants grow vigorously and require large amounts of water. When the new leaves grow to 3-4 leaves, the buds are exposed, and the water should be poured once in combination with topdressing fertilizer. , Generally 5 acres of topdressing urea, 20 kg of diammonium phosphate.
2. Plant management. Timely removal of the stems from the plants was done, so that they could be seen and removed, and they were cleared out and destroyed outdoors. During the growing season, old yellow leaves, diseased leaves, and weak lateral buds should be continuously removed to concentrate nutrition and provide results. Remove excess buds before flowering. The fruit-type cultivar retains 2 order flower buds, while the medium and small fruit cultivars retain 3 order flower buds.
3. Temperature and humidity control. Colonization to dormancy: The daytime temperature is controlled between 20°C and 26°C and up to 30°C. Restoring growth to flowering: daytime temperature is controlled at 20°C-28°C, nighttime 8°C-l0°C, relative humidity 60%. Flowering period: 18°C-22°C during the day and must not exceed 25°C, otherwise pollen development may be affected. Relative humidity in the room is 40%. Result period: 16 °C - 22 °C during the day, no more than 25 °C, and no less than 8 °C - 10 °C in the evening.
4. Flowering-assisted pollination. The amount of ventilation in the greenhouse is small and there are few insects, which is unfavorable to strawberry pollination and fertilization. Assisted pollination can help increase the seed setting rate. Usually put two boxes of bees in a greenhouse of 1 mu or artificial pollination with a brush.
5. Dormant management. Properly simmer the bottom leaves, axillary buds, pour water before winter, and spray to prevent diseases.
6. Fertilizer management. Watering: The greenhouse strawberry grows until it blooms and remains moist until it blooms. After flowering, the amount of water needed to increase should be promptly filled with water. The fruit ripening period needs to control irrigation properly. Top dressing: Before the flowering, apply potassium dihydrogen phosphate and foliar spray foliar fertilizer for 1-2 times with an interval of 10 days. After the fruit is set, it is combined with watering. Mushi urea and phosphate fertilizer l0 kg.
7. Disease prevention and control.
Gray mold. Flowering buds are prevented to prevent botrytis, can be used 25% carbendazim 300 times, 64% caustic soda manganese zinc (antivirus) 1000 times, sprayed every 7 days, a total of 3 times. Can also be used 75% chlorothalonil, 70% thiophanate-methyl, Tuzi special 1500 times, 65% dexamethasone WP 500 times and other spraying control.
Bacterial bacterial wilt. In the initial stage of disease, spray with 100-500106 streptomycin for agricultural use, 7-10 days, spray 3-4 times.
