Soilless Seedling method of Capsicum

In order to prevent the occurrence of seedling diseases and save labor, the method of soilless seedling can be adopted. The length × width × height of the seedling plate is 55 cm × 27 cm × 5 cm, and the plate is divided into 72 spaces, namely the hole plate.

I. use of substrates and sowing methods

Soilless cultivation is mainly based on the mixture of peat and vermiculite at 3:1 instead of soil and farm manure in the seedling plate. Put the mixed seedling substrate into the seedling tray, put a number of seedling trays equipped with seedling substrate together, add a board on top, press down a little hard, because there is a sunken pit in the upper part of each seedling hole, then sow pepper seeds in the seedling hole, sow 2 seeds in each hole, cover it with vermiculite after sowing, make it flush with the seedling plate, and then water it thoroughly with a spray can. Cover the seedling plate with plastic sheet to keep warm and moisturize and promote seedling emergence. Remove the plastic sheeting after the seedlings are unearthed, and leave 1 or 2 seedlings in each hole according to different requirements.

II. Seedling management

The nutrition and water management of seedling emergence with this kind of seedling tray is different from that of conventional seedling cultivation. When the seedlings grow 3-4 true leaves, they need to be irrigated with nutrient solution. The method of interval irrigation with one nutrient solution and one clear water is generally adopted. The nutrient solution can be prepared with urea and potassium dihydrogen phosphate with a concentration of 2 grams per liter of water. The water retention of peat and vermiculite is relatively poor, so compared with conventional seedling cultivation, the watering times are more, the seedling substrate can not be too dry and affect the seedling growth, and the temperature management is the same as conventional seedling cultivation.

Soilless seedling can not only greatly reduce the occurrence of soil-borne diseases in seedling stage, but also has the advantages of slow seedling, convenient transportation, small area and so on.
