Seeding Tray For Greenhouse

seeding tray have 50 holes, 72 holes, 128 holes.

The size of the standard hole disc is 540mm×280mm, and the number of holes is between 18 and 800 due to the different diameters of holes.In the cultivation of medium and small seedlings, 72- 288 holes disc is appropriate.

The advantages of using seedling tray:

(1) Save seed dosage and reduce production cost.

(2) Orderly emergence of seedlings to maintain the consistency of plant seedling growth.

(3) Can be used with various manual and automatic seeder, easy to centralized management, improve work efficiency.

(4) No root damage when transplanting, slow seedling quickly, high survival rate

Seeding Tray Application

for seeding flowers, vegetables

Hole tray, also known as seedling tray, it has become an important tool in the factory seedling production process.From flowers to vegetables, pot growing is one of the most fundamental innovations in modern gardening, promising fast and mass production.The materials used to make the hole plate are polystyrene foam, polystyrene, polyvinyl chloride and polypropylene.Manufacturing methods are blow molding, injection molding.Common vegetable and ornamental seedling hole dish is made of polystyrene material

Seeding Tray Introduction

1) Seeding tray material: 

The materials used to make the hole plate are polystyrene foam, polystyrene, polyvinyl chloride and polypropylene.Manufacturing methods are blow molding, injection molding.Common vegetable and ornamental seedling hole dish is made of polystyrene material.

2)The hole shape of seedling hole disc mainly includes square and round. The matrix of square hole is about 30% more than that of round hole, and the water distribution is more uniform, and the seedling root system is more fully developed

3)The color of the seedling hole disc affects the temperature of the root of the plant.White polystyrene foam plate reflective sex is better, more used in summer and autumn early seedling, in order to reflect light, reduce the heat accumulation of seedling root.In winter and spring, black seedling plate is chosen because of its good light absorption, which is beneficial to green seedling root system

 How to use Seeding Tray

Seedling plate, also known as acupoint plate, the specific operation method:

1. Selection and disinfection of the hole tray: the external size of the hole tray is mostly 54.9×27.8cm, and the hole tray specifications are 72 and 108 holes respectively, which are suitable. Put the seedling tray into a solution of 100 times diluted bleach powder (i.e., 1 kg bleach powder and 99 kg water), soak it for 8-10 hours, and take it out and dry it for later use.

2. 2. Matrix preparation:At present, the commonly used matrix materials for point plate seedling are peat, vermiculite, perlite, etc., more peat: vermiculite: perlite =2:1:1, also should be added in the matrix appropriate amount of inorganic fertilizer and organic fertilizer, generally per cubic meter of matrix to add 2.6 to 3.1 kilograms of nitrogen, phosphorus and potassium compound fertilizer 15:15:15 and 10 to 15 kilograms of organic fertilizer such as flavorless chicken manure.The PH of the matrix is 5.8 ~ 7.0.Peat is a semi-decomposed marsh vegetation with a PH of 3.8 ~ 4.5. It has fine texture and poor air permeability. It is often mixed with vermiculite or perlite.Substrate disinfection.




3. 3. The plate:First of all should be ready to the substrate, will match good substrate in a pan, do not force should be paid attention to when plate pressure, because after compression, matrix physical properties was broken, the air content in the matrix and can absorb water content reduce, correct way is to use scraper from the side of the hole tray to the other party, make each hole tray filled with matrix, especially the corners and rim of the cavity,Be sure to be the same as the hole in the middle, the matrix can not be overfilled, full of each cell should be clearly visible.

4. Pressure: a good plate to pressure, in order to facilitate the seed inserted into the hole, can be specially made pressure hole pressure, can also be installed with a good matrix plate vertical code together, 4 ~ 5 a pile, put an empty plate, hands flat on the plate evenly pressed to the required depth.

5. sowing: the seed point in the pressure point of the dish, each hole a grain, to avoid the leakage of sowing, germination rate is low seeds sowing 2 grains per point.

6. Covering matrix: After sowing, cover the hole plate with vermiculite. The method is to pour vermiculite on the hole plate, scrape from one side of the hole plate to the other side with a scraper, remove the excess vermiculite, cover vermiculite not too thick, and it is appropriate to be flat with the cell.

7. seedling tray into the bed: the sown seedling tray shop in the seedling bed, in time with water will be watered through the seedling tray, watering spray to light and uniform, to prevent the hole in the matrix and seeds out, and then in the seedling bed tiling covered with a layer of film, to prevent the loss of water in the seedling tray.When covering mulching film, some small bamboo strips should be placed on the seedling plate, so that the gap between the film and the seedling plate is not bonded.Can also be in the substrate plate before sowing disk dip into the tank, water from the bottom of the hole plate slowly up the seepage, water absorption is more uniform, and then put into the seedbed.

8. Seedling management.Transplant seedlings to fill the gap: after the emergence of seedlings, the film covering the seedling bed should be removed in time to prevent the film from being uncovered too late and the formation of "tall seedlings".After the cotyledon is expanded, it is necessary to immediately carry out thinning and seedling replacement, pull up the excess seedlings in the single hole and move them into the hole of the missing seedlings, at the same time delete the excess seedlings in the hole, after the missing seedlings are moved and filled, spray water on the seedling bed immediately.Water management: the matrix capacity of seedling in the hole dish is small, the gap is large, the water can be absorbed less, the seedling bed on the seedling water supply buffer is small, a little negligence, easy to produce water loss phenomenon, summer and autumn high temperature season to spray water in the early morning and evening when the climate is cool.
