How to grow strawberry seedlings? Detailed seedling methods and tips shared
How to grow strawberry seedlings? Please introduce the methods. Strawberry seedling methods: 1. Cultivation of mother plants for propagation. To reduce the consumption of nutrients in the mother plants used for propagation and to promote the development of daughter plants, the old leaves and diseased leaves of the mother plants must be removed promptly, and the flower stems must be pinched off; at the same time, spray the plants with 50ppm gibberellin (that is, 1 gram of gibberellin mixed with 20 kg of water), spraying twice in a row...
How to grow strawberry seedlings? Please introduce the methods
Strawberry seedling methods:
1. Cultivation of mother plants for propagation
To reduce the consumption of nutrients in the mother plants used for propagation and to promote the development of daughter plants, the old leaves and diseased leaves of the mother plants must be removed promptly, and the flower stems must be pinched off; at the same time, spray the plants with 50ppm gibberellin (that is, 1 gram of gibberellin mixed with 20 kg of water), spraying twice in a row, with an interval of 7 days between sprays.
2. Timely irrigation and fertilization
Depending on how dry the soil in the seedling plot is, irrigate promptly to maintain soil moisture in the seedling plot. Under normal climate conditions, irrigate the seedling plot once after 3-5 consecutive sunny days; when irrigating, apply frequent light fertilizer at the same time. Apply some diluted human manure or 0.5% compound fertilizer or urea once every 15 to 20 days in the evening.
3. Weeding, loosening the soil, and arranging the runners
Weed and loosen the soil promptly to reduce competition with strawberries for water and nutrients, which helps retain soil moisture and helps the daughter plants take root, ensuring the growth of the daughter plants. When weeding, if daughter plants that have been pulled loose are found, replant them promptly to avoid producing some rootless "floating seedlings"; at the same time, arrange the emerging runners to ensure that each runner has a certain amount of growing space and produces high-quality strong seedlings.
4. Pest and disease control
The main pests and diseases in strawberry seedling plots at present are:
Aphids, red spiders, leaf beetles, tobacco cutworms, leaf spot disease, etc.
Aphids:
Control when they occur. For the pesticide, imidacloprid-type products can be selected, such as 10% imidacloprid at 2500-3000 times dilution.
Red spiders:
Control at the early stage of occurrence. For the pesticide, pyridazinone and propargite-type products can be selected, such as 15% pyridaben 1200 times dilution or 57% propargite 2500 times dilution. Adding 99% Luying 300 times dilution when controlling gives better efficacy.
Leaf beetles:
When damage occurs, use 40% chlorpyrifos emulsifiable concentrate 800 times dilution, or 5.7% Baishude emulsifiable concentrate 800 times dilution for control.
Tobacco cutworms:
In the seedling plot, sex pheromone traps can be used to trap and kill male adults, reducing the population of the next generation. Use 4 traps per mu, with good trapping results; chemical pesticides can also be used for control, such as 0.2% Fuda Jiawei 1500 times dilution, or 40% chlorpyrifos emulsifiable concentrate 800 times dilution, or 5.7% Baishude emulsifiable concentrate 800 times dilution.
Leaf spot disease:
May to June is the peak period for leaf spot disease. Control promptly at the early stage of onset. Promptly clean up leaves and infected parts of plants, and spray with 300g/L kresoxim-methyl nicotinamide water-dispersible granules 1000 times dilution, or 50% Cuibei dry suspension concentrate 3000 times dilution, or 65% Baitai water-dispersible granules 700 times dilution, or 99.1% Luying emulsifiable concentrate 300 times dilution mixed with Yefuke wettable powder 1500 times dilution, or 5% myclobutanil wettable powder 1500 times dilution, or 40% Fuxing wettable powder 4000 times dilution.
