Example Embodiment

[0027] Embodiment 1: the preferred seedling is Bai Rihong, and the specific embodiments are as follows:
[0028] The steps for building a nursery pond are as follows:
[0029] The ground in the plastic greenhouse is plastered with cement, and then a nursery pond is built on it. The length of the nursery pond is determined by the width of the plastic greenhouse. The width of the nursery pond is 1.2m. The depth of the pool is 30cm, leaving a 0.5m aisle between two adjacent nursery pools;
[0030] A Φ15mm PVC electrical casing is inserted on the side wall of each nursery pond, and a socket can be reserved when building the nursery pond. The casing is bent to the other side to form a half elliptical arc on the nursery pond. Install two Φ25mm black or dark PVC or PE pipes in the elliptical arc. The direction of the pipes is according to the length of the nursery pond. The upper and lower pipes are in the middle of the nursery pond. The upper pipe is drilled every 1m before installation. 8mm The hole is drilled on a line, and the pipe is fixed on the top of the elliptical arc with Velcro, with the side with the hole facing down. This pipe is the ventilation pipe for carbon dioxide in the nursery tank. The bottom pipe It is a water pipe for the water in the nursery pond. A four-outlet atomizing nozzle is installed upward every 0.9m on the water pipe. When installing, the nozzles are in a line, so that the water mist can be sprayed evenly. Anywhere in the nursery tank, use the same PVC pipe as the water pipe to make a T-shaped bracket, the height of the bracket is 0.8 meters, and use Velcro to fix the water pipe in the nursery tank, the semi-elliptical arc pipe and the T-shaped bracket together, so that the water pipe is fixed together. In the middle of the nursery pond, the two ends of the water pipe are bent downward and then install a ball valve in an appropriate place. The north end is connected to the main water inlet pipe, and the other end is connected to a section of water pipe at the lower end of the ball valve. The lower end of the water pipe is 8cm away from the cement floor;
[0031] A layer of clean pebbles of Φ2-3cm are laid on the bottom surface of the nursery pond, with a thickness of about 3-5cm, which is a permeable layer, and a drainage hole is left at the bottom of the south side of the nursery pond;
[0032] A layer of permanent magnets with a thickness of Φ70mm and a thickness of 20mm is evenly laid on the top of the pebbles, and 6 permanent magnets are laid per square meter to magnetize the nursery bed. Then spread 20cm thick perlite the size of half a rice grain on it;
[0033] In the water pipeline of the nursery pond, group the nursery ponds into groups of 3, install manual valves and solenoid valves in parallel in the water inlet pipes of each group, and increase the diameter of the water inlet pipes of each group appropriately. 10 Φ70mm thick 20mm magnets are set on the water inlet pipe of each nursery pond to magnetize the water, and electrical control equipment equal to the number of water inlet pipes is installed in the nursery pond to control the solenoid valve for cyclic interval spraying. The pressure of the water inlet should be maintained above 0.4mp. When 2-3 groups of water pipes are opened at the same time, the water mist sprayed by the atomizing nozzle can cover the whole place of the nursery pond;
[0034] Install a manual valve at the inlet of the ventilation pipe of the nursery pond, and seal the other end. The inlet pipe should be connected to the main inlet pipe by reducing the diameter. The diameter of the main inlet pipe is 110cm, which is at the inlet of the main inlet pipe. Install an induced draft fan to facilitate the introduction of carbon dioxide gas into the nursery pond.
[0035] The steps of raising seedlings include: collecting cuttings, cleaning, sterilizing, pruning, soaking in rooting agent, inserting into seedling beds, managing seedlings, and planting in nutrient pots after rooting.
[0036] The specific embodiment: the described cuttings are collected before the sun comes out in sunny days, and can be collected all day in cloudy and rainy days, and the collected cuttings are the parts with twigs above the semi-lignified part, or they can be trimmed during ordinary seedling raising. Twigs coming down.
[0037] The specific embodiment: the cleaning is to clean the soil, dirt, insect eggs, pests, rotten leaves and other sundries on the cuttings.
[0038]The specific embodiment: the disinfection and sterilization is to soak the cuttings with carbendazim or thiophanate-methyl solution for disinfection and sterilization.
[0039] The specific embodiment: the pruning is to prune the cuttings, which can be one leaf and one bud, or two leaves and two buds. The branches and leaves are too dense or the buds at the top can be processed into multiple buds, and the cuttings are between 5-10cm. Avoid damaging the cortex of the cuttings.
[0040] The specific embodiment: the soaking rooting agent is to soak the cuttings to make them take root, and the rooting agent uses the finished ABT1 No. 200PPM to soak the base for one hour, and soak the base for 1-2 cm.
[0041] The specific embodiment: the inserting into the nursery bed is that before inserting the cuttings into the nursery bed, the substrate in the nursery bed is sprayed and soaked, and then the substrate is scattered and leveled, and the depth of the cuttings inserted into the nursery bed is 2-3cm, and the cuttings are The plant spacing and row spacing should be less than 50% with the leaves overlapping, while avoiding damage to the pruning at the base of the cuttings, and the part where the cuttings are inserted into the nursery bed should be closely combined with the substrate of the nursery bed.
[0042] This specific embodiment: the described seedling management is that after the cuttings are inserted into the nursery bed, the cuttings are sprayed immediately, and the cuttings and the nursery bed should be sprayed through the first spray, so that water flows out from the south drain hole of the nursery bed, and then in the Sterilize the cuttings and seedling beds that have been inserted into the nursery bed on the same day, and then adjust the spray interval and spray duration appropriately during the day. Water does not need to be sprayed at night. When there is still 2/3 of the water, the next watering can be carried out. The standard for the duration of the watering is that the leaves do not wilt, and the watering interval in the subsequent callus period is 1/2 when the leaves are still on. The next watering can be carried out, and the number and amount of watering should be appropriately reduced during the rooting period. When more than 75% of the cuttings have secondary roots, the frequency and amount of watering should be reduced.
[0043] The specific embodiment: the described planting into the nutrient pot after rooting means that the cuttings are transplanted into the nutrient pot in a timely manner after rooting.

Example Embodiment

[0044] Embodiment 2: Preferred seedlings are tea leaves:
[0045] The steps different from Example 1 are: the described soaking rooting agent is to soak the cuttings to make them take root, and the rooting agent uses No. ABT1 and No. GGR6 mixed solution 200PPM to soak the base for 6-8 hours, soak the base 1-2cm, and the other steps are implemented with the same implementation. example 1.
[0046] The beneficial effects of this specific embodiment are:
[0047] 1. Shorten the seedling time of seedlings. Most varieties can grow into seedlings within 45 days, and some varieties can even grow into seedlings in 15 days. Compared with ordinary cuttings, they can grow into seedlings in 3 to 4 months or even longer. greatly shortened the time.
