Seedling flower dwarf attention point

1. Strengthen trimming and shaping. Flowers and trees grow to a certain height and timely picking the heart, taking the opening branching angle and twisting, bending and shaping, inhibiting the growth of the apex, shortening the vegetative growth cycle and promoting the flowering result.

2. Chemical adjustment. The chemical synthesis of growth inhibitors promotes dwarfing. When transplanting the seedlings into the pots, mix a certain amount of paclobutrazol in the culture soil, spray or apply 0.15% to 0.25% paclobutrazol in the growing season, or use growth inhibitors such as chlormequat and B9 to inhibit the cells. Elongation and growth, promote cell division and thickening growth, reach the leaf fertilization and strong, the crown is dwarf and compact, and the flower is more fruity, which enhances the ornamental value.

3. Use dwarf varieties. The characteristics of the dwarf varieties, the buds have strong branching power, the branching parts are low, the branching angle is large, the internodes are short, and the plant shape is compact. The main root is not obvious, the lateral roots are developed, and there are many roots.

4. Yuxiao strong seedlings. Adopting nutrient seedlings, limiting the development of the roots in depth, promoting the development of the roots, and correspondingly inhibiting the growth of stems and leaves on the ground.

5. Prepare the culture soil. The cultivated soil is the basis of the potted flower forecasting plant. It is required to be rich in organic matter, good in agglomerate structure, fertile and loose, and comprehensive in nutrition. It is made up of a mixture of humus soil, garden soil, pond mud, peat soil, river sand, organic fertilizer, phosphate fertilizer, bone powder and grass ash. The pH value is slightly acidic to slightly alkaline, and the adaptability of different flower varieties to pH is adjusted.

6. Broken roots on the radicle. The flower seedlings are planted in pots, and the short radicle (main root) is cut. When transplanting, the lateral roots are spread around and layered. For example, if the chrysanthemum is on the basin, only two-thirds of the culture soil will be added. With the growth of the plant, the soil will be gradually cultivated, and several old leaves at the base will be buried, which will promote the thickening of the base, and grow large leaves at the near-pot. .

7. Change basins, control fertilizers, and make water. Potted flowers are mainly based on nutrient-based soil. Therefore, it is necessary to change the culture soil by changing the pots. Generally, the pots are changed once a year to two years. According to the growth of the plants, the small pots are changed into large pots, and the old soil is replaced with new ones. Combine the basin, carry out rooting and pruning, improve the recommended tree structure, and promote short stout. Control nitrogen fertilizer, increase the application of phosphorus and potassium fertilizer, avoid the excessive moisture of the waterlogging, in order to prevent the long and rotten roots. In particular, at the peak of growth, water and fertilizer should be produced, so that the potted soil sees dry and wet, saves water and shrinks, promotes stability, and achieves more branches, more flowers, shorter branches and shorter plants.
