Cultivation techniques for Ledu long chili peppers

Chili peppers belong to the Solanaceae family. Developed root system, tolerant to drought, prefers warmth, and is a warm loving crop. The suitable temperature for seed germination is 24-28 ℃, with a daytime temperature of 20-28 ℃ and a nighttime temperature of 16-20 ℃ during the growth period. The relative humidity of the air should be maintained at 70-80%, and sufficient sunlight is needed throughout the entire growth period. The flowering and fruiting period, low temperature and humidity, or high temperature and drought can cause a large number of fallen flowers and fruits. The soil requirements are not too strict, but fertile sandy soil is better. Chili peppers grow poorly and are prone to death in low-lying areas with stagnant water

1. Variety Selection

Ledu County's protected area mainly selects Ledu long chili peppers for cultivation, with a very small portion cultivating sweet peppers. Ledu Changchili pepper has a moderate growth potential, with a plant height of 95 centimeters, a development degree of 80 centimeters, dark green leaves, 12 nodes at the beginning of flowering, and a cone-shaped fruit with a longitudinal diameter of 24 centimeters and a transverse diameter of 4.2 centimeters. The fruit is dark green, the mature fruit is dark red, and the flesh is 1.3 centimeters thick. The average yield per mu is about 4000 kilograms. Spicy and fragrant, with excellent quality, won the Silver Award at the National Expo

2. Sowing and seedling cultivation

1. Preparation of seedbed. For general nutrient soil seedling cultivation, choose uncultivated field soil, fully decomposed farmyard manure, plant ash, and mix them evenly in a ratio of 1:1:1. Add 8-10 grams of 50% carbendazim or 70% methylthiophanate per square meter of bed soil for soil disinfection treatment. Then spread the nutrient soil into the seedbed, with a thickness of 10 centimeters, or fill it with sufficient bottom fertilizer in a nutrient bowl

2. Seed sowing and treatment

Use 150 grams of seeds per acre. Blanch the seeds in hot water at 55 ℃ for 15 minutes without stopping stirring. Wait for the water temperature to drop to 30 ℃ and soak for 6-8 hours, or soak in a 0.1% calcium permanganate solution for 10 minutes. Rinse the solution with clean water and soak the seeds. Then wrap them in a clean damp cloth and place them in an environment at 25-30 ℃ to promote germination. Sow the seeds when they are white

Sowing: Winter cultivation in energy-saving solar greenhouses. The Ledu area has determined to sow and raise seedlings from late July to early August, and cultivate them in winter and spring from late August to early September. Planting and seedling cultivation in ordinary greenhouses during winter and spring in mid to late October, and in plastic greenhouses in late December. The plant spacing is generally 10 * 10 cm, and after sowing, the soil is covered by 1-2 cm, followed by plastic film to maintain temperature and increase ground temperature

3. Seedling management: After sowing and before emergence, insulation should be the main method, maintaining 25-30 ℃ during the day and 20-22 ℃ at night. After emergence, remove the plastic film in a timely manner. After the seedlings are fully planted, maintain a temperature of 20-25 ℃ during the day and 12-15 ℃ at night. Interplanting should be carried out when the seedlings have grown to 1-2 true leaves. Ten days before planting, the seedlings are refined at low temperature and gradually reduced in temperature. The temperature is maintained at 20-22 ℃ during the day and 10-15 ℃ at night, with strong winds. The standard seedling age is 80-90 days, the seedling height is about 20 centimeters, there are 9-10 true leaves, the stem thickness is 0.4-0.6 centimeters, the plant is robust, and there are no pests or diseases

III. Planting

1. Soil preparation and fertilization: Apply 5000-6000 kilograms of high-quality decomposed farmyard manure, 150 kilograms of hemp residue, 50 kilograms of diammonium phosphate per mu, and treat the soil with 2.5 kilograms of diquat or 2 kilograms of carbendazim, deeply plow 40 centimeters, and irrigate with sufficient water

2. Planting: When the lowest indoor temperature reaches 8 ℃ and the ground temperature reaches 12-15 ℃ at a depth of 10 centimeters, and it remains stable for one week, planting can be carried out. The cultivation values for energy-saving solar greenhouses in winter are from mid to late October to early November, and for winter and spring are from late November to early December. For ordinary greenhouses, the cultivation values are in late January of the second year. For plastic greenhouses, the cultivation values are in mid April, with a large row spacing of 70 centimeters, a small row spacing of 40 centimeters, and a plant spacing of 30-35 centimeters

IV. Planting and Management

1. Ventilation and Temperature and Humidity Management: After planting, in order to promote seedling growth and maintain high temperature and humidity, ventilation is temporarily not allowed. The temperature is maintained at 25-30 ℃ during the day and 16-18 ℃ at night, and the indoor relative humidity is maintained at 70-80%. During the period from seedling growth to fruit setting, the temperature should be maintained at 20-25 ℃ during the day and 13-17 ℃ at night, with a relative humidity of 60-70%. Ventilation begins when the indoor temperature reaches around 25 ℃, and in the afternoon when the temperature drops to 15 ℃, the ventilation opening is closed for insulation. Ventilation should gradually increase from small to large, and sudden ventilation at high temperatures is strictly prohibited. The temperature during the result period remains at 25-30 ℃ during the day and 15-17 ℃ at night. When the lowest external temperature stabilizes above 15 ℃, ventilation can be carried out day and night

2. Watering: When planting, it is better to use planting water. After 10-15 days of slow planting, depending on the soil moisture, watering can be done once. Then, control the water and wait for the seedlings until the bell pepper begins to swell. After the bell pepper begins to bear fruit, watering should be done a second time. Afterwards, watering should be done according to the soil moisture, and the soil should be kept moist regularly. Watering should be done on sunny mornings, with light watering and avoiding excessive watering

3. Topdressing: The principle of fertilization is to apply heavy base fertilizer, more organic fertilizer, and increasing potential phosphorus fertilizer. In the early stage, nitrogen fertilizer is emphasized, and phosphorus and potassium fertilizers are increased during the peak fruiting period. After harvesting the bell peppers, the first application of topdressing should be combined with watering. 2000-3000 kilograms of decomposed farmyard manure and 15-20 kilograms of diammonium phosphate should be applied per mu. During the peak fruiting period, fertilization can be carried out 2-3 times with watering. 10 kilograms of urea or 15 kilograms of diammonium phosphate should be applied per mu, and foliar fertilizers such as 0.3% potassium dihydrogen phosphate, 500 times dilution of Fululing, or 400-600 times dilution of Gaomei should be sprayed alternately every 15-20 days from the initial flowering period to the late fruiting period

Fifth, Prevention and Control of Major Diseases and Pests

Currently, the main diseases and pests of chili peppers in Ledu County are root rot, blight, anthracnose, aphids, and leaf miner flies. On the premise of strengthening agricultural prevention and control, root rot disease can be treated by irrigating roots with a mixture of methyl frost copper, anti-virus alum, and copper ammonium, and treating the soil with pesticides before planting. Plague can be treated with Prick, Lvxiang No. 2, Antivirus alum spray and root irrigation. Anthrax can be controlled by spray of mancozeb and ethylmanganese. At the same time, insect mite light and alfodine spray can be used to control leaf miner and aphid

In recent years, Ledu County has closely focused on the work idea of "expanding and strengthening branded vegetables", and regarded Ledu long chili peppers as a pillar industry for agricultural efficiency and farmers' income increase. Through adopting scientific planning, contiguous planting, financial support, technical guidance, demonstration and driving, and strengthening operating procedures, various effective measures have been taken to continuously develop and grow the Ledu long chili pepper brand
