Breeding methods and precautions for basil seeds
Planting herbs on balconies has become a new trend among urban people. Basil seeds are popular for their unique aroma and medicinal value. However, many novices often encounter problems such as thin plants and yellowing leaves during the cultivation process. This article will systematically sort out scientific cultivation methods based on actual planting experience. Key points of environmental control Temperature and light management Maintaining a constant temperature environment of 15-25 ° C is the key to growth. In winter, it is recommended to use transparent insulation covers to protect seedlings. Ensure 6 hours of direct light every day, and south-facing window sills or open-air balconies are ideal. At noon in summer, you need to filter strong light with a sunshade net to avoid burning leaves. The balance between soil and water uses the gold ratio of humus: perlite: vermiculite =5:3:2, and the bottom layer is paved with 3 cm ceramite to enhance drainage. Watering follows the principle of "seeing dry, seeing wet", watering thoroughly in 5-7 days in spring and autumn, and spraying in the morning and evening in summer to increase moisture. Use the bamboo stick insertion method to detect soil moisture, and replenish water can be replenished when the surface layer is 2 cm dry. Reproductive management strategy Scientific pruning promotes growth-promoting plants are topped for the first time when they grow to 15cm, retaining 4 pairs of true leaves. Apply thin fertilizer every 2 weeks after lateral branches develop, and it is recommended to dilute seaweed fertilizer 1000 times. Regularly remove the old leaves at the bottom to ensure ventilation and light transmission of the plant. Cutting propagation techniques: breeding methods and precautions for basil seeds
Select semi-lignified branches and reserve 3 bud points and oblique them 45 degrees. Use perlite as the cutting substrate and maintain 80% air humidity, and take root in 2 weeks. Spring and early autumn are the best breeding periods, and the survival rate can reach 90%. Common problems handling pest and disease control plan Aphids can be sprayed with 1:20 detergent water at the beginning, and azadirachtin biopesticides can be used in severe cases. Use garlic extract to irrigate roots every month to prevent root rot, and isolate diseased plants immediately when discovered. Keep the plant spacing above 30cm to enhance air circulation. In response to special circumstances, premature flowering is prone to occur during the high temperature period in summer, and flower ears should be cut off in time to concentrate nutrients. If frostbite occurs in winter, it needs to gradually warm up and not suddenly change. Damaged leaves will be pruned after spring warms up. Rotate the flowerpot regularly to ensure that the plants receive balanced light.
Through precise environmental control and scientific maintenance methods, basil seeds can be harvested in multiple crops throughout the year. The key is to grasp the balance between light intensity and moisture management, and with timely pruning and shaping, even a closed balcony can create a fragrant vanilla garden. By regularly observing the status of the plants and adjusting maintenance strategies in a timely manner, you can continue to harvest fresh basil leaves.
