Pepper Floating Seedling Note Five Questions

With the development of science and technology, pepper seedlings have been replaced by floating seedlings in the past, which not only saves cost and time, but also facilitates management. The survival rate after transplanting into the field is high, but the following issues must be noted during the seedling raising process:

First, seed disinfection

The selected pepper seeds are soaked in warm water of 50°C-55°C for 15-20 minutes, and then they are extracted and dried until they are semi-dried with 50% carbendazim wettable powder (with 0.3 种子 of seed amount), and then the seeds are Broadcast into the mounted float tray. This practice is mainly used to prevent capsicum virus disease and seedling stage damping-off diseases and diseases.

Second, the substrate disinfection

The selected substrate is sprayed with 600 times 50% carbendazim or thiram wettable powder to wet the substrate and then placed in a float tray.

Third, the nursery pool nutrient solution preparation

The pre-concentration should be low, with 0.15% compound fertilizer solution of N:P:K (15:15:15), appropriate supplemental nutrition from the middle stage to transplanting, the concentration of nutrient solution can be adjusted to 0.25% (ie 100 kg of water against 0.25 Kg compound fertilizer solution).

Fourth, timely prevention and control of pests and diseases

Can use 65% of dexamethasone 800 times to control the pepper disease, gray mold, damping-off disease occurrence and aphids, thrips damage.

V. Appropriate ventilation, removal of membranes

After emergence, when the leaves are 1-2, the membranes will be uncovered from 8am to 10:30am to prevent leggy, cultivate compact and robust seedlings, and strengthen ventilation from 12 noon to 4:30 pm to prevent burning seedlings.
