The Planting Method and Disease and Pest Control of Screw Pepper
The editor introduces the planting method and knowledge of disease and pest control of screw pepper, which is very useful experience. It is recommended to collect it!
The Planting Method and Disease and Pest Control of Screw Pepper
Peppers prefer warmth and are not cold-resistant. From the time of planting to the time of seedling recovery, it is essential to maintain a relatively high temperature and humidity environment in the greenhouse to promote root growth. Usually, on the day of planting, the ventilation opening is not opened to prevent the wind from causing the seedlings to flash. The main diseases include scab disease, (T-J) disease, blight, viral disease, white rot disease, and bacterial wilt. Prevention is key for diseases, and it is best to spray the medicine early, whether there is disease or not.
Screw pepper is a first-generation hybrid crinkle pepper, generally higher in yield than similar varieties, cold-resistant, disease-resistant, short internodes, dense fruit setting, deep green fruit, and suitable for planting in Shandong, the five provinces in Northwest China, and Hainan.
For planting screw pepper in facilities, the main choices are early spring and overwintering crops. The overwintering crop is planted from early August to early September and ends by late June of the following year.
Screw pepper is harvested during the New Year and Spring Festival holidays, when prices are higher, making it the most profitable time for planting. The early spring crop is planted in greenhouses in mid-to-late March and ends in September to October, with good management.
Planting Method for Screw Pepper
1. Soil Preparation:Apply enough manure as a base fertilizer, with 12-15 cubic meters of well-rotted high-quality chicken manure and cow dung per mu. The root system of screw pepper is strong, so it is necessary to deeply cultivate the soil to a depth of over 25cm to thoroughly mix the manure and soil.
2. Planting:Plant on small high ridges, either in double rows with a row spacing of 70-75cm and a plant spacing of 40-45cm, or in single rows with a row spacing of 90-110cm and a plant spacing of 30-33cm.
Prevent excessive irrigation. Install a drip irrigation system on the ridges for planting and irrigation. After planting, promptly apply a slow-release fertilizer and medicine water to promote rapid seedling recovery and early entry into the flowering and fruiting stage.
3. Environmental Management from Planting to Seedling Recovery:Peppers prefer warmth and are not cold-resistant. It is essential to maintain a relatively high temperature and humidity environment in the greenhouse from planting to seedling recovery to promote root growth. Usually, the ventilation opening is not opened on the day of planting to prevent wind damage to the seedlings.
4. Water and Fertilizer Management:After planting peppers, start with seedling setting to promote root growth. If the ridges are not covered with mulch, combine weeding and loosening the soil.
After the peppers have set, end the seedling setting, keep the soil moist but not wet, and water frequently during the flowering and fruiting stage. Use Green Continent high-potassium balanced fertilizer to prevent soil nutrient deficiency causing blossom and fruit drop.
5. Pruning Method:The pruning method is simple and not strictly required. First, remove all side branches below the door pepper, remove the old and diseased branches from the top, and then depending on the growth, you can prune to double, triple, or quadruple stems.
The goal is to keep the entire pepper plant balanced, the center not blocked, and to enhance ventilation and light in the field.
Greenhouse planting of screw pepper has many diseases, and disease prevention is important. Apply sufficient fertilizer to cultivate strong plants to prevent diseases in advance, and Green Continent Plant Protection will assist you in cultivating strong seedlings again.
Common Diseases of Screw Pepper
So, what are the common main diseases of screw pepper? The main diseases include scab disease, (T-J) disease, blight, viral disease, white rot disease, and bacterial wilt. Prevention is key for diseases, and it is best to spray the medicine early, whether there is disease or not.
For scab disease, (T-J) disease, and viral disease, you can use agricultural streptomycin, kill or methyl thiophanate, ridomil or carbendazim spray control; viral diseases generally cause mosaic and curling leaves, which can be prevented by spraying virus A or pepper curling spray.
For white rot disease and bacterial wilt, prevention is key, strengthen soil disinfection, and apply more lime. Or use 50% carbendazim, 500 times solution to water the roots or apply five chlorine nitrobenzene medicine soil to the roots at the beginning of the disease.
The above is a specific introduction to the planting method and disease and pest control of screw pepper. I hope you will like it!
