Pay attention to these problems in the floating nursery of pepper
With the development of science and technology, the past cold bed nursery of pepper seedlings has been changed to floating seedlings, which saves cost and time and is easy to manage. It has the advantages of high survival rate after transplanting in the field, but the following issues must be paid attention to during the seedling process:
1. Seed disinfection treatment: Soak the selected pepper seeds in warm water at 50℃-55℃ for 15-20 minutes, then take them out and let them dry until semi-dry and dress them with 50% carbendazim wettable powder (0.3‰ of the amount of seeds) ) Afterwards, the seeds will be sown into the installed floating tray. This practice mainly prevents pepper virus disease and damping-off and blight at the seedling stage.
2. Disinfection of the substrate: spray the selected substrate 600 times with 50% carbendazim or thiram wettable powder until it is wet and then put it into the bleaching tray.
3. Preparation of the nutrient solution in the nursery pond: the concentration should be low in the early stage, use 0.15% compound fertilizer solution of N:P:K (15:15:15), supplement nutrients properly in the middle stage to before transplanting, and the concentration of the nutrient solution can be adjusted to 0.25 % (Ie 0.25 kg compounded in 100 kg of water).
4. 65% daisen zinc 800 times can control pepper blight, gray mold, damping-off, and damage from aphids and thrips.
V. Moderate ventilation and uncovering the seedlings: After emergence, take care of 1-2 leaves, remove the film and refine the seedlings from 8 am to 10:30 in the morning to prevent excessive growth, cultivate squat and strong seedlings, from 12 to 4 noon Semi-enhanced ventilation to prevent seedling burning.
