Pepper planting techniques

The temperature requirement of pepper is between eggplant and eggplant. The optimum temperature for seed germination is 23-30℃, and it cannot germinate below 65438 05℃. Pepper seedlings need high temperature, low temperature and slow growth. At the beginning of flowering and fruiting, the optimum temperature is 20-25℃ during the day and 15-20℃ at night. The soil temperature is too high at the fruiting stage, especially when the strong light shines directly on the ground, which is not conducive to root growth and is easy to cause toxin disease and sunburn.

2. Soil preparation and base fertilizer

Pepper should not be continuous cropping, nor should it be continuous cropping with eggplant, tomato, potato and tobacco. The plot for planting pepper requires good drainage, convenient irrigation and drainage, and requires deep ploughing. It is best to cultivate in winter and loosen the frozen soil to improve the soil and eliminate overwintering pests and pathogen spores.

3. Sowing and raising seedlings

① Selection of seedbed: The seedbed should be a plot with the back facing south, dry and refreshing, convenient water source and no solanaceae crops.

(2) Seedbed preparation: It is best to dig deep the baked soil on the seedbed in dog days, sprinkle a layer of human and animal manure on it, dry it, and cover it with a film to prevent fertilizer loss when it rains.

③ Sowing: Before sowing, fully wet, refine and level the bed soil. The width of seedbed is generally 1.5- 1.7 meters ... Generally, seeds are not soaked to accelerate germination. Early-maturing varieties are generally sown in 65438+ 10, and late-maturing varieties are generally sown in February-March. Planting an acre requires sowing 75- 120g.

(4) Seedbed management: generally, management is not needed from sowing to emergence. When seedlings are found, the plastic film should be removed immediately, otherwise high seedlings will be formed. After emergence, the film was uncovered at 9: 00 a.m. on sunny days and still covered at 4: 00 p.m.

Step 4 plant

The soil temperature of pepper should be above 65438 05℃. Early planting can not achieve the goal of early maturity because of low soil temperature, slow growth and slow flowering. Plant spacing: the row spacing of early-maturing varieties is 40-50 cm, the plant spacing is 26-33 cm, and each hole 1-2 plants. The row spacing of late-maturing varieties is 66-73 cm, the plant spacing is 50-60 cm, and each hole 1 plant. Choose sunny afternoon for planting, and water the seedbed in the morning to facilitate seedling pulling.

5. Tian Tuan management

① intertillage weeding: after the field planting survives, shallow intertillage should be carried out in time. Plants began to grow and concentrated in intertillage once. Before the factory closes, cultivate again. Intertillage combined with weeding and ridging.

(2) Fertilizer and water management: after planting, it is necessary to catch up with the seedling fertilizer in sunny days, and the dosage should not be too much and too thick each time, otherwise it will easily lead to excessive growth and delay flowering and fruiting. When the first and second layers bear fruit, more fertilizer should be applied to promote fruit growth.

(3) Harvest seeds: As fresh food, harvest more green fruits and red fruits. As a dry pepper, it is necessary to harvest the red ripe fruit in time, otherwise it will affect the growth and fruit of the plant.

Extended data:

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.

dry red pepper

Also known as horn pepper, Ninghua is famous. It is famous at home and abroad for its bright red color, transparency, thin skin, delicious taste, rich oil and moderate spicy taste, and sells well in Hong Kong, Macao, New Zealand, Malaysia and other countries and regions.

Pepper was introduced to China in the late Ming Dynasty and widely cultivated as an annual in China. There are also perennial woody pepper trees in Yunnan. After the pepper is dried, the commercial dried pepper is obtained. As condiments, dried peppers and pepper products have always been commodities in international trade. Dried Chili and Chili products are important export condiments in China.
