1. Choose improved varieties?
You can choose excellent varieties with strong disease resistance and stress resistance, suitable for spring and wheat stubble cultivation, such as Bullet No. 2, Red Pepper No. 8, etc. ?
2. Cultivate strong seedlings?
Chaotian pepper should be planted in large seedlings, and the seedling age should be 60 to 70 days. In order to ensure that the seedlings are strong, the seedlings should be raised in a sunny border or a small bow shed. Spring pepper seedlings can be raised in late February, and wheat stubble pepper seedlings should be raised in late March. The seedbed soil should be loose and fertile, which is the key to cultivating strong seedlings. Before sowing, expose the seeds to the sun for 2 to 3 days, then soak them in 10% potassium permanganate aqueous solution for 15 minutes, then remove them and rinse them thoroughly before sowing.
After sowing, the seedbed should be heated, that is, the mulch film should be sealed tightly to increase the soil temperature. The daytime temperature should be controlled at 20°C and the night temperature should be controlled at 10°C. Seedlings can emerge in about 10 days.
3. Planting?
Chaotian pepper likes moisture and is afraid of water. It is better to choose fertilizer-preserving, loose and ventilated loam, sandy loam or clay loam. The pH value of the soil is 6.5 to 8. Each acre can be applied with 3 to 5 cubic meters of fully decomposed high-quality farmyard manure, or 50 to 80 kilograms of compound fertilizer with three elements of nitrogen, phosphorus and potassium (each containing 16%), which can be increased or decreased appropriately according to the fertility of the land. In order to facilitate drainage and irrigation, sorghum cultivation should be adopted.
4. Field management?
(1) Cultivating and cultivating the soil. Timely cultivating and cultivating the soil can promote the growth and development of the pepper root system, increase the soil temperature, and help preserve moisture. ?
(2) Topdressing fertilizer. If the base fertilizer of spring pepper is sufficient, top dressing can be appropriate according to the growth of the plant. Top dressing is particularly important for wheat stubble peppers, and top dressing can be done as early as possible.
(3) Watering and drainage. Chaotian pepper has a shallow root system and is afraid of drought and waterlogging. Especially during the fruiting period, if there is a lack of water, the yield will be seriously affected. Water frequently and lightly to keep the soil moist.
(4) Topping. The branches of Chaotian pepper have obvious layers, one is the main stem fruiting branch, the second is the lateral fruiting branch, and the third is the auxiliary lateral fruiting branch. Its main output is composed of fruits from the side branches. Therefore, artificial topping should be performed as soon as the main stem buds to promote the development of side branches. If the side branches appear late, the fruits will not mature and should be removed in time.
5. Prevention and control of pests and diseases?
(1) Diseases. Diseases that harm Chaotian peppers include stem disease, damping off, viral diseases, epidemic diseases, etc. They should be prevented and treated as early as possible, and the principle of prevention is more important than cure should be adhered to.
(2) Pest pests. The main ones include cotton bollworm, tobacco caterpillar, corn borer, etc., which can be sprayed with 3000 times liquid of high-efficiency cypermethrin or 5000 times liquid of Caesar EC. It is necessary to check frequently and carefully at ordinary times, and control when there are few insects and when they are young. When the weather is dry, pay attention to preventing and controlling red spider mites, aphids, etc.
:
Chaotian pepper, a variant of pepper, belongs to the Solanaceae family and is a perennial semi-woody plant. The stems are upright, with single leaves alternate; the flowers are white, and the flowering period is from early May to the end of July. The fruits are clustered at the ends of the branches and have the same flavor as green peppers. The whole plant is used as medicine. The rhizome is warm in nature and sweet in taste. It can dispel wind and cold, relax muscles and activate collaterals, and has insecticidal and antipruritic effects.
