1, sowing time:
The best sowing time for floating seedlings is at the end of mid-February, that is, rain (February 18 to 20). After annual rain, the external temperature starts to rise, which is favorable to the emergence of pepper seeds. .
2, install floating seedling shed:
The open terrain with a flat terrain and a sunny leeway was fitted with small steel sheds according to the standard of 9.70 meters in length, 1.35 meters in width, and 0.90 meters in height.
3, choose qualified matrix:
The matrix requires good physical properties, good permeability, and stable chemical properties. The floating seedling substrate produced by the Zunyi Luyang Valley Agricultural Technology Co., Ltd. is mainly prepared from peat, fermented chaff, expanded perlite and vermiculite that have been treated with high temperature sterilization. The product was selected and pumped to the Guizhou Provincial Inorganic Inspection Station many times and was tested according to the above-mentioned standards. Both were qualified. The floating seedling substrate has a volume of 70 L and can hold 16 trays (160-float floating tray).
4, seedling tray selection and disinfection:
Use 162-well seedling trays to raise seedlings; reuse floating seedling trays with 0.05-0.1% potassium permanganate or 0.5-1.0% copper sulphate spray disinfection, and then rinse with water and use after drying.
5, clean nursery environment:
Before sowing, weeds and rubbish around the nursery shed should be thoroughly removed to maintain a good nursery environment and reduce the spread of diseases and insects.
6, nursery shed disinfection:
Fumigation with methyl bromide for 24 to 48 hours was used for disinfection of nursery sheds. After water was injected into nursery ponds, bleach was added at a rate of 1,000 kg of water plus 10 g of bleach, and the shed was closed for more than 30 hours for disinfection.
7, sowing requirements:
Seed sowing, sowing 1 to 2 per hole. Cover the seed in two ways. One is to put a bamboo sieve into a small amount of matrix, and then cover the back and forth of the seeds on the well-seeded plate, so that the seed can not be covered, and the substrate cannot be covered too thick so as to avoid seed emergence. This screen cover is suitable for smaller seeds of tobacco, vegetables, etc. Another cover type method is suitable for larger seed diameters, that is, after filling the seeds, filling the matrix, and finally scraping off the excess matrix of the disk with a wooden board, exposing the cells to reduce algal blooms on the disk surface.
8, nursery water:
Use clean, pollution-free sources of water.
9, seedling management:
After the emergence of pepper, pay attention to the temperature and humidity control, the temperature is too high, cover the shade net in the top film, open the film to air two acres; if the temperature is too low, pay attention to keep warm.
10, timely raise seedlings:
Pepper seedlings reached two hearts and ten days before transplanting. The seedlings containing N16%, P2O58%, and K2O16% were mixed in a ratio of 1:1000, and the water was added to the flotation pool to apply the seedlings twice.
11. Pest control:
Use carbendazim 800 times spraying twice to prevent damping-off and blight; use 20% of virus A wettable powder 500 times solution to spray 2 times to prevent virus disease; use kung fu and other pyrethroid insecticides to spray Apply pest control. When spraying medicine, it is necessary to spray at the same time in the nursery shed and the nursery shed.
