Dwarfing methods of seedlings and flowers

Seedlings and flowers are often seen in life, and they have a good embellishment effect. Today, the editor will share them with you.

1. Strengthen pruning and plastic surgery. Attention should be paid to the dwarfing of seedlings and flowers, the coring of flowers and trees should be taken at a certain height in time, and the opening branch angle and twist and twist should be adopted to restrain the top growth advantage, shorten the vegetative growth cycle and promote flowering and fruiting.

two。 Chemical regulation. Chemical synthetic growth inhibitors were used to promote dwarfing. When the flower seedlings were transplanted into the pot, a certain amount of paclobutrazol was mixed in the culture soil, 0.15% to 0.25% paclobutrazol was sprayed or poured during the growing period, or growth inhibitors such as dwarf, B9 and other growth inhibitors were used to inhibit cell elongation and growth, promote cell division and thicker growth. to achieve the purpose of strong leaves and fat branches, compact crown, multi-fruit flowers, and improve ornamental value.

3. Dwarf varieties were selected. Dwarf varieties are characterized by strong branching ability of buds, low branching position, large branching angle, short internodes and compact plant shape. The main root is not obvious, the lateral root is developed, and there are many fibrous roots.

4. Raise short and strong seedlings. Adopt nutrition bowl to raise seedlings, limit the development of main roots, promote the development of fibrous roots, and correspondingly inhibit the growth of aboveground stems and leaves.

5. Prepare the culture soil. Culture soil is the basis of potted flower prediction, which requires rich organic matter, good aggregate structure, fertile and loose, and comprehensive nutrition. It is made of rotten leaf soil, garden soil, pond mud, peat soil, river sand, organic fertilizer, phosphate fertilizer, bone meal, plant ash and so on. The pH value is slightly acidic to slightly alkaline, and the adaptability of different flower varieties to acidity and alkalinity should be adjusted.

6. Break the radicle and put on the basin. Plant the flower seedlings in a pot, cut the radicle (main root), spread the lateral root around when transplanting, and fill the soil layer by layer. For example, when the chrysanthemum is on the pot, only 2/3 of the culture soil is added at the beginning, and the soil is gradually cultivated with the growth of the plant, burying a few old leaves at the base, making the basal stem thicker, growing thick leaves near the mouth of the basin, and the plant is short and strong.

7. Change the basin, control fertilizer and make water. Potted flowers are mainly based on nutritious soil fertilizer, so it is necessary to change the pot and renew the culture soil constantly, generally changing the pot once a year to 2 years, according to the growth of the plant, the small pot for the big pot and the old soil for the new soil. Combined with changing the basin, pruning the root and pruning, improving the recommended tree structure and promoting sturdiness. Control nitrogen fertilizer, increase the application of phosphorus and potassium fertilizer, and avoid excessive waterlogging humidity, so as to prevent excessive growth, rotting roots and dead seedlings. Especially in the peak growth period, it is necessary to make water and fertilizer control, so that the basin soil can see dry and wet, save water and reduce fertilizer, promote stable growth, achieve more branches, more flowers, short dense branches, and dwarf plants.

So much for sharing with you. I believe you all have a certain understanding. I hope this article will be helpful to you.
