How to efficiently raise bell pepper seedlings? Key technical points explained

I. Select good varieties

Use varieties with good heat tolerance, strong disease resistance, good quality and fast growth.

II. Raising seedlings

Use plug tray seedling raising. Put the prepared nutrient soil or peat soil into the plug tray, water thoroughly, and sow after the water has seeped down. Before sowing, the seeds can be pre-germinated in advance; if they are coated seeds, they can also be sown directly. Sow one seed per cell, with the radicle pointing downward, cover with about 1 cm of soil after sowing, then spray water carefully and thoroughly. The nutrient soil can be mixed yourself or purchased, but note that the nutrient soil needs to be disinfected, generally treated with metalaxyl or carbendazim, which gives relatively good control of damping-off, Rhizoctonia rot and many other seedling-stage diseases.

III. Seedling-stage management

After sowing, in order to promote uniform emergence, maintain a relatively high temperature of 30°C-35°C during the day and 15°C-20°C at night. After emergence, lower the temperature appropriately to prevent leggy growth. During the day 25°C-28°C, at night 14°C-17°C. Pay attention to timely watering to keep the substrate moist. The seedling age is generally about 40 days, and they can be transplanted once they grow to 4 true leaves. Shen Xiangjun
