The technical method of raising seedlings with seedling tray and how to use it.

Plug: Select a suitable plug and soak it in bleaching powder 100 times solution for 8- 10 hour before use. Substrate: peat, vermiculite and perlite are mixed together according to the ratio of 2: 1: 1, and then 2.6-3. 1 kg NPK compound fertilizer and10-/5 kg decomposed chicken manure are added to each cubic meter of substrate. Tray loading: put the substrate into the tray and poke out the sowing hole. Sowing: Generally, one seed is sowed in each hole.

First, the technical method of seedling raising in seedling tray and the use method of seedling tray.

1, plug

(1) The plug is usually 54.4 cm long, 27.9 cm wide and 3.5-5.5 cm high. According to the number of holes, it can be divided into 50 holes, 72 holes, 98 holes and 128 holes. According to the plug weight, it can be divided into 130g and 170g g light plugs.

(2) Before use, soak it in bleaching powder 0/00 times of/kloc for 8- 10 hour, and dry it for later use.

2.[ number] matrix

Peat, vermiculite and perlite are mixed according to the ratio of 2: 1: 1, and then 2.6-3. 1 kg NPK compound fertilizer and 10- 15 kg decomposed chicken manure are added to each cubic meter of substrate. The ph value is controlled between 5.8 and 7.

3. Flat loading

(1) Put the prepared matrix into the cavity plate. Specific operation: pour the substrate into the hole tray, and then move it from one direction of the hole tray to the other with a scraper, so that each hole tray is filled with the substrate.

(2) After the tray is installed, poke out the seeding holes with fingers or special hole presses.

Step 4: Sowing.

(1) Sow seeds into sowing holes, and sow one seed in each hole. If the germination rate is low, plant two seeds in each hole.

(2) After sowing, cover with vermiculite. Specific operation: pour the vermiculite gently on the plug, and then move it from one direction of the plug to the other with a scraper to remove the excess vermiculite.

Step 5 manage

(1) Place the plug on the seedbed, thoroughly irrigate it with clear water, and then lay a layer of plastic film on the seedbed. There are some small bamboo strips between the plastic film and the plug, so that there is a certain gap between the plastic film and the plug.

(2) Remove the plastic film in time after emergence. After cotyledons spread out, the seedlings became thinner and replenished.

(3) Manage the temperature and air humidity.

Second, the advantages of seedling tray

1. Compared with the conventional seedling raising method, the seedling raising cost is reduced by 30-50%.

2. After the seedlings cultivated in the seedling tray are planted, the emergence delay is fast and the survival rate is high.

3. The emergence rate per unit area of seedling tray is higher than that of conventional seedling raising.

4. Compared with conventional seedling raising, the seedling age is shortened by 10-20 days, and the labor efficiency is improved by 5-7 times.

5. The weight of each seedling cultivated in the seedling tray is 30-50g, and the base has strong water retention capacity, and the root system is not easy to disperse, which is convenient for long-distance transportation.
