Chapter 35 How to Cultivate Strong Flower Seedlings

To cultivate good and strong flower seedlings, the quality of the seeds is the key.It is necessary to choose seeds with the correct variety, good quality, and full seeds for seedling cultivation.Sowing soil requires loose fertile, well-drained.The sowing time is determined according to the different habits of various seeds, the local climate environment and the purpose of cultivation.There is no certain limit on the sowing period of greenhouse flowers, and it can be carried out all year round.Generally, species that bloom in winter and early spring are sown between July and September, such as cineraria and cattail flowers.Most of the remaining species can be sown in spring.The sowing method and post-sowing management are as described above.After the seedlings are unearthed, the covering should be removed in time, and they should be exposed to sunlight gradually to prevent the seedlings from yellowing.

When drilling and sowing seedlings are too dense, appropriate thinning should be carried out in time to prevent the seedlings from being slender and lodging.When thinning, strong seedlings should be selected, weak seedlings and leggy seedlings should be removed, and other seedlings and weeds mixed with them should be pulled out.When the flower seedlings grow 2 to 3 true leaves, the seedlings can be divided.By dividing the seedlings, the distance between the plants can be increased, the nutrient area of ​​the seedlings can be expanded, the sunshine can be increased, the air can be circulated, and the seedlings can grow stronger.Cutting off the main root when transplanting seedlings can promote the growth of lateral roots, and it is easier to restore growth when transplanting; transplanting can inhibit excessive growth and make clusters dense.Potassium fertilizers are often applied in addition to nitrogen fertilizers at the seedling stage to promote root development and improve plant lodging and disease resistance.At the same time strengthen daily management.For vegetative propagation, materials that grow vigorously and are free from diseases and insect pests should be selected for propagation.
