Key points for cultivation of greenhouse peppers in autumn

The post-harvest cultivation of greenhouse peppers refers to delaying the production of peppers to the cold season in late autumn through the protection facilities. This cultivation method has high temperature and high humidity in the early stage, low temperature in the middle and late stages, and slow growth of pepper. The following points should be noted in management:

1. Water and fertilizer management. On the basis of pouring water, the seedling water was poured on the third day after planting. Subsequently, the soil was ploughed in time, and the soil was sealed. The pepper was planted in the ditch. After the soil was ploughed, the original ditch was turned into a ridge. The original ridge back became a ditch, but the soil should not be too high, 13 cm is appropriate. Appropriate seedlings after the soil is sealed, so that the root system develops in depth and reaches the deep roots. At this time, if there is too much water and fertilizer, it is easy to cause the plant to grow long and the fruit setting rate is lowered. The humidity of the pepper is not high. If the air humidity is often higher than 50% to 60%, it is easy to cause the plant to grow long, resulting in falling flowers and falling fruits. When the first layer of fruit reaches a size of 2 to 3 cm in diameter, the stems, leaves and flowers of the plant grow at the same time. Watering and topdressing should be carried out in time, and 500-1000 kg of manure and 10 kg of urea should be applied per mu. After fertilization, it should be cultivated in time to improve soil permeability and improve soil fertility.

In the fruiting period, the plants grow tall, and the body and the results are carried out simultaneously. In order to prevent premature aging of plants, it is necessary to timely harvest the lower fruits (men pepper and pepper) and strengthen the watering. The acres are diluted with 5 to 10 kilograms of true roots and mixed with urea and other chemical fertilizers to keep the soil moist. The plants continue to grow and flower fruit.

In the end, it is necessary to strengthen water and fertilizer management, promote the results of peppers and increase production. Topdressing can be carried out alternately with watering. After pouring water for one time, it can be combined with watering and top dressing once, and ternary compound fertilizer or potassium dihydrogen phosphate 10 kg or true root 5-10 kg per acre, every 7-8 days. Watering once.

2. Temperature management. When the temperature outside the shed is still higher than 15 °C, the wind can be released day and night, the better the ventilation, the stronger the pepper, the less the falling and falling fruit. If the temperature outside the shed falls below 15 °C, the pepper grows slowly and the fruit expands slowly. The shed film and the shed door should be tight at night, and the wind can only be released when the temperature is high during the daytime, so that the shed temperature is kept at 20 °C~ 25 ° C, in order to facilitate the expansion of the fruit. Before the minimum outside temperature drops to near 0 °C at night, the temporary small arch shed should be immediately buckled for cold protection. If it is too late to buckle the small arch shed, you can use a plastic film to cover the pepper tree to avoid freezing the plant to ensure the growth of young fruit. At noon on sunny days, the wind should be released in the lee at a short time to eliminate harmful gases in the shed, supplement oxygen and carbon dioxide, reduce the temperature inside the shed, and reduce the occurrence of diseases.
