Chili is a seasoning that people often eat in people’s lives. In some places, three meals are inseparable from chili. Although it is autumn and winter when the temperature is relatively low, there are still many chili growers, but there are also many. My friend reported that the output of peppers was not high at this time, so let's take a look at the reasons.

Reasons for low yield of pepper in autumn and winter and its solutions

1. Reasons for low yield of pepper in autumn and winter

1. During the growth process, malformed fruits and split petals are also easily formed due to poor root growth, insufficient fertilizer and water, poor light, long plants, and poor reproductive growth.

2. Although the temperature turns cold in autumn, sometimes the temperature is still relatively high. If the temperature is high and humid during the flowering and fruiting period, the low temperature in the later stage of the growth period is low. When the temperature is higher than 30 degrees or lower than 15 degrees, the pepper cannot be pollinated normally, which is very easy Form deformed fruit and rigid fruit.

3. In the fruiting period, the temperature is low, it is difficult for the roots to absorb phosphate fertilizer, and it is easy to appear too low anthocyanin, so the fruit appears purple spots.

2. Solution

1. Cooling and controlling humidity during growth

Therefore, the temperature and humidity should be controlled during the growth period of the pepper. The temperature should be controlled between 25-28 degrees during the day, 15-18 degrees at night, and the air humidity should be maintained at 60%-70%. It is conducive to the growth and development of pepper fruit, and helps to improve yield and quality.

2. Increasing temperature and insulation in the late growth period

In the later stage of pepper growth, the temperature is low, and the light is weak and short. Therefore, measures such as heat preservation and cold protection and increasing light should be taken. At the same time, fertilizer and water management should be strengthened, phosphorus and potassium fertilizers, and potassium dihydrogen phosphate foliar fertilizer should be sprayed. Fruit growth and development provide sufficient nutrients to promote normal fruit development.

3. Coordinate reproductive growth and vegetative growth

In the later stage of pepper growth, reproductive growth and vegetative growth are carried out together. If too much nitrogen is applied, the plants will grow longer, and normal vegetative growth will exceed reproductive growth, and normal fruit development will be poor. Therefore, in the flowering and fruiting period, we should strengthen the fertilizer and water, increase the application of phosphorus and potassium fertilizer, and use less or no nitrogen fertilizer. In addition, we should pay attention to watering. Flood irrigation is not suitable. At the same time, we should properly cultivate the soil to improve soil permeability.
