1. Seedling cultivation?

How to breed Jinbuhuan plants? Jinbuhuan potted flower arrangement tutorial. The seeds are small and the germination rate is low. Generally, there is no need to sow seeds. The cutting method or division method is commonly used for propagation. Cuttings are suitable for The temperature is 18~25℃. ?

① It is best to choose strong branches that are in the flowering stage for cuttings. Leave 3 to 4 nodes at the base and cut them off. Remove the top buds and then cut them into small sections of about 10 cm, leaving the upper part of each section. There are 3 to 4 leaves, cut off other leaves, wait for the wound to dry slightly before cutting. ?

② The cutting substrate can be clean river sand, perlite or soil. The cutting depth is about 3 to 5 centimeters. Every three cuttings are divided into a group, and the cuttings are arranged in a triangle to facilitate cluster growth. After watering thoroughly, place it in a bright place, pay attention to moisturizing the soil (can be covered with film), and it will take about 1 week to take root. ?

③If transplanting is required, it is usually done when the cuttings are about 30N. The soil for planting must be fully decomposed organic fertilizer first. Generally, 3 seedlings are planted in each hole, with a planting depth of about 5 cm. After planting, the soil is compacted slightly, and then enough water is poured. It can be managed normally in about a week. 2. Daily management?

① It is better to cultivate in a place with sufficient sunlight, and it can also grow in semi-shade. It is very drought-tolerant. Generally, it will not be sprinkled until the soil is dry. If it is sprinkled, it will be watered thoroughly. In the season when the branches and leaves are growing vigorously, it can be sprayed with water once in the morning and morning. It is better to keep the leaf surface completely wet. In the dry season, attention should be paid to preventing waterlogging to prevent root rot. ?

② It likes warmth and grows slowly below 15°C. It is best to move it indoors for heat preservation when it is below 5°C. When it is above 30°C, pay attention to ventilation and cooling. Apply compound fertilizer once a month, and pay attention to it in time. Get rid of weeds. There are almost no pests and diseases. There may be aphids infestation in spring and summer. Just be careful to eliminate them by hand as soon as possible. ?

③ It is perennial and has strong tillering ability, but it is best to re-cut or divide the plant after 2 to 3 years of cultivation to prevent the plant from gradually weakening or prone to disease. It is best to divide the plants in early spring when new buds have not sprouted. Try to bring as many root buds as possible. Generally, 3 to 4 plants are divided into 1 clusters, and each mother plant can be divided into 4 clusters at most. Before planting, dip it in plant ash to disinfect. The planting depth should be the same as before the division. After digging the hole and planting, compact the soil slightly near the roots, and then water it thoroughly. Generally, it can survive in 3 days. 3. Harvesting?

It can be harvested when the plant height is about 20 centimeters. Weak branches can not be harvested temporarily. When picking, 3 to 4 nodes should be left at the base to allow new branches to sprout. Apply 1 after picking. Secondary compound fertilizer, you can also sprinkle appropriate amount of plant ash. Generally, it can be harvested once every two months. The fresh stems and leaves can be used directly or dried in the sun for later use. 4. Key points of cultivation?

1. Seed selection and seed treatment?

From October to November every year, select 3- to 4-year-old seeds that have plump seeds, are free from diseases and insect pests, and turn red when mature. Pick the fruit, put it in a bamboo sieve, rub the peel off, wash it, dry the surface moisture, and soak the seeds in 50% thiophanate 1000 times for 10 minutes for disinfection. Panax notoginseng seeds tend to lose vitality after drying, so they should be sown as they are harvested, or preserved by stratification. ?

2. Farming?

The spacing between rows and plants is 6 cm × 5 cm, and shallow ditches are opened for sowing on demand. The soil is covered, and the border surface is covered with a layer of straw and other materials to keep the border surface moist and moist. Suppress weed growth. 70,000 to 100,000 seeds per acre are used, which is equivalent to 10 to 12 kilograms of fruit. After tilling and watering, if covered with silver-gray mulch, it can retain water, save fertilizer, and increase production. ?

3. Seedling management?

When the weather is dry, water should be sprinkled frequently, drains should be drained after rain, and weeding should be done regularly. Topdressing in the seedling stage is usually based on phosphorus and potassium fertilizers, and is usually applied three times, in March, May, and July. The light transmittance of the ceiling in the seedling stage should be adjusted according to the changes in light intensity in different seasons. ?

4. Transplanting?

The seedlings are transplanted after one year of cultivation, usually from December to January of the following year. It is required to raise seedlings, select seedlings, and transplant them at the same time. When starting seedlings, be careful not to damage the roots and buds. When selecting seedlings, diseased, injured, and weak seedlings should be eliminated and cultured in stages. Panax notoginseng seedlings are divided into three levels based on size and weight. Those with 1,000 roots weighing more than 2 kilograms are level 1; those with 1.5 to 2 kilograms are level 2; those with a root weight of less than 1.5 kilograms are level 3. The spacing between transplanting rows is 15 cm × 15 cm.
