Detailed Explanation of Key Techniques for Growing Peppers in Greenhouses
Most vegetables nowadays are grown in greenhouses, first to ensure supply, and second to increase income. This is the case with the peppers commonly used in cooking, so what are the techniques for growing peppers in greenhouses?
What are the techniques for growing peppers in greenhouses?
1. Land preparation and seedling raising
Before planting peppers, the plot should be plowed to a depth of 10-15cm. Apply 5000kg of barnyard manure per mu, which can be mixed with 15kg-20kg of superphosphate, with short irrigation and short drainage ditches, with all ditches connected, so that the field does not accumulate water after rain. Sow and raise seedlings from the Spring Equinox to Qingming; after the seedbed is prepared, irrigate enough bottom water and do a good job of disinfection. After the seedlings are raised, harden them off in the open air in a timely manner.
2. Reasonable transplanting
When transplanting, cover with shallow soil, and then gradually cultivate soil and close the ridges. Because pepper plants are compact and suitable for dense planting, the general density for green pepper production is 3000-4000 holes per mu (double plants), with a row spacing of 50-60cm and a plant spacing of 25-30Cm. Generally, double plants or 3 plants per hole are mostly used.
3. Field management
After planting is completed, appropriate watering is needed. After the seedlings recover, timely watering is needed, and watering can stop once the young seedlings are stable. When the fruit grows to three centimeters, watering is needed along with fertilization. When watering, water frequently but use a small amount each time, and never irrigate heavily, to avoid some problems caused by overwatering the plants, which will also affect quality and yield.
4. Pest and disease management
Greenhouses are used to grow vegetables most of the time, especially in winter, providing suitable environmental conditions for pests and diseases to overwinter and reproduce, which will make vegetable pests and diseases increasingly serious. Therefore, the prevention and control of pests and diseases is also the key to successful vegetable cultivation in greenhouses.
Peppers should be harvested at the right time after maturity, generally before Frost's Descent.
