1, the temperature management after planting to maintain high temperature and humidity, generally covered with plastic film outside the grass tweezers to make it airtight. Daytime temperature 28 °C -30 °C, night 18 °C -20 °C. After about 7 days, the seedlings will be defoliated. At this time, proper ventilation can be performed and the temperature can be lowered. The temperature is 26°C-28°C during the day and 15°C-18°C during the night. Because of early spring cultivation, the outside temperature is low, so ensuring a higher temperature is the key. The temperature is too low, poor fertilization, affect the flowering results. When the outside temperature is stable at 25°C during the day and 15°C or more at night, it can be ventilated overnight and remove some of the film.
2. After cultivating the cultivator and the fertilizer and water, the seedlings can be watered according to the soil moisture condition and then the seedlings can be planted. During the seedlings cultivating 2-3 times, and earthing. The watering in the early stage should not be too large. After sitting on the first fruit, the amount of watering should be properly increased, especially in the fruiting period, the soil should be kept moist. The topdressing usually starts after the first fruit begins to swell and is applied to 20 kg of compound fertilizer per acre with water. After that, the top dressing is applied every 20 days depending on the situation, and it is usually applied with watering.
3, pruning and auxin regulation In order to make the plants do not shade each other due to luxuriant foliage, need to be pruned, generally after the first fruit set, the following branches of the bifurcation destroyed, and removal of the inflorescence of weak branches; In the middle and late period, the old leaves, diseased leaves and yellow leaves are removed in time to maintain a certain plant type, which is beneficial to the ventilation of the plants and the results are good. The color peppers, like other common peppers, are exposed to the adverse weather such as low temperature, which can easily cause drop and fruit drop. To prevent this from happening and increase the fruit setting rate, 2,4-D can be used. Generally, 10-15 ml/kg 2,4-D or 25-30 mg/kg tomato spirits are applied on flower stalks or sprayed on flowers during flowering.
