capsicum frutescens, a variety of capsicum, is a perennial semi-woody plant of Capsicum in Solanaceae, which is often cultivated as an annual; Its plant height is 3 cm-6 cm, with many branches, erect stems and alternate leaves; The flowers are white, and the flowering period is from the beginning of May to the end of July. The fruits are clustered at the branches and have the same flavor as green peppers. The whole herb is used as medicine, and its rhizome is warm and sweet, which can dispel wind and cold, relax tendons and activate collaterals, and has the effects of killing insects and relieving itching.

key points of planting:

1. The suitable temperature for seedling

germination is above 25℃. If plastic film shed is used for heat preservation, it can be cultivated all the year round. Seedbed or pot sowing is the best way for sowing. The soil should be fertile and loose, and the soil should be screened and disinfected. The simple disinfection method is sun exposure, fumigation and high temperature treatment. The purpose is to kill the invasion of bacteria or insect eggs in the soil on young pepper seedlings, and give them to seedlings before sowing. After the young shoots are unearthed, proper amount of human urea or .1% urea solution can be poured for 1-2 times. After pouring, the foliar fertilizer solution can be washed away by spraying clear water with a fine watering can to avoid burning the young leaves. When the seedlings grow to 5-6 real leaves, they can be transplanted.

2. Potting

One plant should be planted in each pot with a diameter of 15-25 cm, and 2-3 plants can be planted in a larger pot. The soil used should mainly contain farmyard manure, supplemented by phosphate fertilizer, urea and compound fertilizer. The soil in the pot should be loose, water-saving, and keep enough sunshine. If the indoor temperature is suitable in winter and properly maintained, it can continue to bloom, and the fruit viewing period of potted plants can often be extended to the New Year.

3. Planting in the ground

For planting in the open field, the time is required to be from March to May every year. Before transplanting, the field must be planted with sufficient base fertilizer, and more than 1, kilograms of human and animal manure and 5 kilograms of phosphate fertilizer or compound fertilizer should be applied per mu. Transplanting density requires row spacing of 4-5 cm, plant spacing of 3 cm, sufficient water for moisture retention and clean weeding. At the beginning of flowering, 1 kg of urea should be used per mu, and plant vitality elements such as Yemianbao and Fengchanling should be applied conditionally.

4. Pests and diseases

The common diseases are epidemics, and both seedling and adult plants are susceptible to diseases. At seedling stage, the stem base showed dark green waterlogged soft rot and collapse. Spraying or watering 8 times of 5% mefenone wettable powder or 5 times of 64% antivirus alum wettable powder in time for prevention and control. Cotton rot can occur in both seedling stage and adult plants. The fruits of five-colored peppers planted in the open field at seedling stage

5 and harvested < P > generally begin to mature in the middle and late August, so they should be harvested in time to increase profits and improve economic benefits. The cut mature peppers can be put on the market or hung in a ventilated and dry place to dry into dried peppers for eating or selling as commercial peppers. Onset, stem base rot, shrinkage and death. Spraying 72.2% Prick solution 4 times or 15% hymexazol (Tujunxiao) 45 times at the initial stage of the disease.

6, prevention and control of three falls

The leaves, flowers and fruits of pepper have a great negative impact on yield and quality. According to Yin Hongyu's experiment of Shixing Pepper Professional Cooperative in Gucheng County, Hengshui, after the plants appear buds, 25 grams of "Blue Classic"+3 ml of "Shilesun" or 3 ml of "Strong Man" are sprayed once every 3 days for 3-4 times (it can be used alternately with 3 times of bactericide and 15 times of agricultural streptomycin, which can effectively prevent "three falls" and significantly increase production.
