Pepper, alias: horn pepper, long pepper, vegetable pepper, lantern pepper, Latin scientific name: capsicum annuum L., Solanaceae, pepper is an annual or limited perennial herb. Stems subglabrous or puberulent, branches slightly zigzag. Leaves alternate, the top nodes of branches are not elongated to form twins or clusters, oblong, oval, ovoid or ovoid-lanceolate, entire, short tapering or acute at the top, and narrow wedge at the base; Flowers solitary, drooping; Calyx cup-shaped, inconspicuously 5-toothed; Corolla white, lobes ovate; The anthers are grayish purple. The fruit stalk is thick and drooping; The fruit has long fingers, the tips of which gradually become sharp and often bend. It is green when it is immature, and turns red, orange or purple when it is mature, which is spicy. Seeds flat kidney-shaped, pale yellow.
The early growth stage of pepper is the germination stage, which is usually unearthed about 5-8 days after germination and sowing. The first true leaf appears about 15 days until the bud is the seedling stage. The flowering period is from the first ear to the door pepper. The fruiting period is from fruit setting to seedling drawing. The suitable temperature of pepper is between 15-34 degrees. The suitable temperature for seed germination is 25-30℃, and it takes 5-7 days to germinate. When the temperature is lower than 65438 05℃ or higher than 35℃, the seeds will not germinate.
The seedling stage requires high temperature, 25-30 degrees during the day, and 15- 18 degrees at night is the best. Seedlings are not tolerant of low temperature, so pay attention to cold protection. If the pepper is 35 degrees, it will drop flowers and fruits.
Pepper has strict requirements on conditional moisture, and it is neither drought-tolerant nor waterlogging-tolerant. I like dry air conditioning.
