1. Seedling transplantation

The nutrient soil is a mixture of 30% peat soil, 30% yellow heart soil, 30% coconut bran and 10% decomposed soil fertilizer, with a pH value of 5.0 -7.0, if it is too acidic, use quicklime or plant ash to adjust it; if it is too alkaline, use sulfur powder, ferrous sulfate or aluminum sulfate. After 10-15 days of stacking, put it into a container with a specification of (7-10) cm × (12-16) cm. Keep a nutrient cup for later use and drench the seedbed with water before transplanting the seedlings.

When the seedlings grow 3-4 true leaves, select strong seedlings for transplanting in batches in the morning, evening or rainy days. When starting seedlings, keep the root system intact, transplant one plant per cup, and the transplant depth is slightly higher than the root neck (after watering and compacting the substrate, the root neck will be flush with the substrate surface). After transplanting, pour enough root water in time and shade more than 50%. The nutrition cups are arranged neatly and closely in a width of 1 meter, leaving a 30 cm wide working channel between the rows. ?

Water and fertilizer management: Spray water on the leaves within 7 days after transplanting, once in the morning and evening to keep the substrate moist. In the later stage, follow the principle of "seeing dry and seeing wet" for watering. Spray 0.2% compound fertilizer solution once 14 days after transplanting. From now on, spray once every 10-15 days, gradually increasing the concentration to 1.0%.

2. Planting of large seedlings

Preparation before planting: The planting time is from the Great Cold to Qingming. Choose a hard or soft plastic container with a size of (28-35) cm × (28-35) cm. The soft plastic container has 3 rows of drainage holes on the wall. The substrate is 50% garden soil, 30% peat soil and 20% decomposed compost, with a pH value of 5.5-7.5. Set aside after 10-15 days. ?

Colonization method: Before filling the substrate, wet the substrate first, knead it into a ball with your hands, spread it out, and then pack the substrate firmly to 10 cm from the mouth of the container. Select seedlings that grow robustly, have neat plant shapes, and are free of diseases and insect pests. Carefully remove the nutrient cup from the seedlings, keeping the soil ball intact, and move it into the center of the container. Add additional substrate and compact it. The substrate should be 1 cm away from the container mouth. First put a little garden soil into the bottom of the planting bed and level it.

Rigid plastic containers are placed directly on the planting bed, and the spacing between plants and rows is 0.8-1 meter. The soft plastic container is placed in a pre-dug soil pit in the planting bed. The soil pit should be slightly larger than the container, and the filling soil should be fully compacted to keep the container balanced. Water thoroughly after transplantation.

3. Top dressing: Apply thin fertilizer more frequently. Apply 0.5% ternary compound fertilizer solution once 14 days after transplantation, and then gradually increase the concentration to 1%. When the temperature is 15-25°C, top-dressing should be done every 30 days; when the temperature is 26-35°C, top-dressing should be done every 15 days. Control fertilization in late November, spray 0.5% potassium dihydrogen phosphate solution every 5 days, and spray 3 times in a row.

4. Drainage and irrigation: Within 7 days of transplantation, spray water once every morning and evening to keep the matrix moist. After watering, follow the principle of "see dry, see wet". When the temperature is high in summer, water it once a day in the morning or evening, and spray once in the morning and afternoon. In rainy seasons, water should be drained in time, and watering should be controlled from late November.

5. Plastic pruning: Pruning requires a main trunk height of 25-35 cm, 3-5 main branches, and more than 3 sub-main branches, evenly distributed. The crown of the tree is naturally oval, and the plant shape is neat and plump.

Prune 1-2 times a year, 10-15 days before the spring shoots germinate. For unbranched single seedlings, cut the top about 40 cm from the ground, and select strong, branch angles and positions. Suitable 3-5 spring shoots are used as main branches. After the summer shoots are extracted, 2-3 summer shoots of each spring shoot are left as deputy main branches, and the rest are cut off. Pruning mainly involves light pruning, while also removing weak branches, overly dense branches, and diseased and insect-infested branches.

Select a mother tree that is more than 15 years old, has vigorous growth, robust development, and is free of diseases and insect pests. When the fruits turn purple and black, they can be collected in batches. The seed collection time is September to October. After the fruits are collected, wash off the peel and flesh, float away the empty seeds, take out the plump seeds that have sunk to the bottom, and place them in a ventilated and cool place to dry. The dried seeds will be inspected in accordance with the "Forestry Seed Inspection Regulations". ?

Seed storage: When sowing cannot be carried out in time, the seeds need to be stored in wet sand. Mix the seeds with clean river sand, mix and place in a clean, cool place. The humidity of the sand should be such that it can be kneaded into a ball and loosened by hand. The amount of sand should be 2-3 times the volume of the seeds. The storage time should not exceed 180 days.

Notes

1. Soil is the carrier of flower planting. The quality of the soil directly affects the growth quality of flowers. If there are substances in the soil that are not easy for flowers to survive or grow, they will Directly leading to failure of flower planting. The choice of soil should vary according to the type of flowers. First, go to the place of origin of the flowers to check the composition of the soil in the place of origin of the flowers. Use the soil of the place of origin of the flowers as a benchmark for blending. You can also choose a relatively It is a more general soil.

General-purpose soil is mainly composed of leaf mold soil, fine sand and garden soil evenly mixed. This kind of soil has a relatively balanced nutritional content and is suitable for most flowers, allowing them to grow vigorously and healthily.

2. If flowers want to grow robustly and healthily, they must receive appropriate light according to their growth habits. For flowers that like strong light, they must be planted in a location with strong light. , and flowers that do not require much sunlight should take measures to get sunlight suitable for their own growth. Only in this way can the flowers themselves grow healthily.
