Color pepper field management points

Temperature management

After planting, high temperature and high humidity should be maintained. Generally, straws are covered with plastic film to make them airtight. Daytime temperature 28 °C ~ 30 °C, night 18 °C ~ 20 °C. About 7 days after the slow seedlings, this time can be appropriate ventilation, and reduce the temperature during the day 26 °C ~ 28 °C, 15 °C ~ 18 °C at night. Because it is 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.

Intertillage and fertilizer management

After easing the seedlings, watering may be performed according to soil moisture conditions, and then seedlings may be applied. During the seedlings cultivating 2 or 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.

Pruning and auxin regulation

In order to make the plants not shade each other due to lush foliage, pruning needs to be performed, generally after the first fruit set, the lateral branches below the bifurcation are knocked out, and the weaker shoots that grow inwards are removed; the old leaves are promptly removed in the middle and later stages. Diseased leaves and yellow leaves maintain a certain plant type, which is conducive to plant ventilation, and the results are good. The color peppers, like other common peppers, are subject to 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. In flowering, 10-15 ml/kg 2,4-D or 25-30 mg/kg tomato spirit is applied to flower stalks or spray flowers.
