Sawdust is a kind of cheap soilless culture medium, light, water absorption and air permeability, which has a great effect on flower cultivation. The newly transplanted flowers and trees, especially the ones sent by post, are withered and waiting to die due to the long time of mailing. At this time, if planted in the nutrient soil with high fertilizer content, the seedlings will be burned, and the soil without fertilizer will be planted in the basin. After watering, the soil will easily harden without air, and the new seedlings will suffocate.
For example, the sawdust is added with appropriate amount of nutrient soil to plant new seedlings. Because the sawdust is loose, breathable, heat preservation and moisture preservation, after a period of time, new roots are growing in the old roots of new seedlings, making the seedlings come back to life and recover their vitality.
Take the fresh sawdust and put it into the plastic bag; then put in some cake fertilizer. If there is chicken and rabbit manure, it is better to add enough water and use the rice swill. Cover or seal the opening of the bag, put it at a higher temperature, ferment and rot after 1-2 months, until it turns dark brown.
Then air it until it is half dry and mixed with the soil. It can be used as pot soil to cultivate flowers and trees, which can grow green branches and leaves, with beautiful and fragrant flowers; it can be used as nutrient soil for flower seedlings, which has the wonderful function of promoting the healthy growth of flowers and seedlings.
When the potted flowers and trees are used to change pots, the sawdust mixed with 1 /3 of fine coal slag, and the dry manure properly mixed (the flower fertilizer purchased in the flower shop is better), can be used as the nutritive soil for potted flowers. The damaged roots of seedlings can be recovered quickly when they change pots, the roots are easy to absorb the nutrients of sawdust, and the flowers and trees can flourish rapidly after changing pots.
For potted flowers under cultivation, when the potted soil is half dry, loosen the potted soil with tools, mix the above sawdust, add more dry fertilizer appropriately, put it on the surface of the potted soil, then water it fully, turn the sawdust and potted soil gently a week later, gradually mix the two, and then you will find that the potted flowers are more and more luxuriant.
