In the management of early-maturing peppers in spring, the most important ones are fertilizer water, trimming branches and temperature illumination. Nowadays, many farmers are peppers planted in the arch shed, so today Xiaobian talks about the cultivation techniques and management points of the spring arch shed pepper. First, fertilizer management The cultivation time of early-maturing cultivation of pepper arch sheds is relatively short, the results are concentrated, and the results are large. The amount of quick-acting fertilizer in the base fertilizer should be appropriately increased. Each mu of concentrated high-quality chicken manure or manure dry 3~4 m, high-quality compound fertilizer about 75kg, calcium magnesium phosphate fertilizer about 100kg, the base fertilizer should be applied deep, so that the loam is evenly mixed. After applying the base fertilizer, the fertilizer is no longer applied before the fruit is placed. The pepper is swollen during the expansion period, and the appropriate amount of organic fertilizer solution or potassium nitrate is applied. After 10 days, the urea is applied once to prevent premature aging. In late May, after the shed film was removed, the foliar topdressing was combined with disease prevention to make up for the lack of root absorption. It can spray 1000 times of potassium dihydrogen phosphate or 100 times of compound fertilizer extract, once every 7~10 days. When planting, the planting water is planted, and after the pepper seedlings start to grow new leaves, the water is poured again. After that, the pepper will not be watered until the door is placed, so as to maintain a higher temperature and promote the pepper seedlings. After the pepper is placed in the fruit, it should be watered in time. After that, it should be watered. Keep the ditch moist and not dry. In the rainy season, it is necessary to drain the shovel in time to prevent water accumulation for a long time. Second, the way to sort out the branches The planting density of early-maturing cultivation of pepper in the spring arch shed is relatively large, and it is prone to crowding, and should be properly pruned. The method of arranging branches suitable for early maturing cultivation of small arch sheds in spring is mainly irregular pruning. When the side branches grow to about 15 cm, the side branches under the door pepper are knocked off. In the middle and late stages, the lateral branches of the excessively dense areas were appropriately thinned according to the conditions of the ridges in the field and the results of the plants. Third, temperature and lighting control 1, temperature management The space inside the small arch shed is small, and it is not suitable for heating. When the temperature of the spring shed is low, it is mainly based on heat preservation. Generally, the daytime temperature is maintained at 20~32°C, the temperature does not exceed 35°C, and the nighttime temperature is not lower than 10°C. 1 At night, cover the small arch shed with a layer of grasshoppers, which can generally increase the temperature of the shed by more than 4 °C; 2 paper made of multi-layer kraft paper is covered on a small arch shed for heat preservation, generally can increase the temperature above 2 °C; 3 Add the old film on the arch shed, generally add a layer of old film to increase the temperature by about 2 °C; 4 Windy areas can set up wind barriers in the north and northwest of the small arch shed, which can significantly increase the temperature of the shed. At the end of the day, the temperature inside the shed rises, and attention should be paid to preventing high temperatures. The daytime temperature does not exceed 32 °C, and the nighttime temperature remains around 20 °C. 2, ventilation management Generally, when the temperature in the shed rises above 30 °C in the low temperature period, ventilation is started, so that the maximum temperature does not exceed 35 °C. The wind should be released from the top opening of the arch shed. Do not uncover the wind from the shed film to prevent the cold air from directly blowing onto the plant. During the high temperature period, when the temperature in the shed rises to 25 °C, ventilation begins, and the maximum temperature is controlled within 32 °C. When the wind is released, first put the wind on the top, then put the wind on the ground. The space of the small arch shed is relatively small, the temperature is easy to change, and the wind does not let the wind blow. Generally, before and after the release of air, the short-term temperature drop in the shed does not exceed 5 °C, and the maximum does not exceed 10 °C. The above is the key point of planting technology and management of spring arch shed pepper. The root system of pepper is weak, the rooting ability is poor, and it is greatly affected by the change of soil temperature. Therefore, many farmers use the shed to plant, hope that the above contents can help the farmers.
