Latest Causes and Solutions for Poor Development of Autumn-Winter Crop Peppers

Peppers are a common vegetable in our daily lives and an indispensable seasoning in stir-fries. They are widely grown across China, and can be seen whether grown in greenhouses, in open fields, or on balconies, which many people now love. But during the cultivation of autumn-winter crop peppers, quite a few vegetable growers have reported poor fruit development. So what causes it? Let's take a look.

I. Causes of Poor Fruit Development in Autumn-Winter Crop Peppers

1. Although temperatures turn cooler in autumn, it can still be fairly hot at times. If it is hot and humid during flowering and fruiting, and then low temperature and insufficient light occur in the late growth stage, when the temperature is above 30 degrees or below 15 degrees, peppers cannot pollinate normally, and deformed fruits and stiff fruits are very likely to form.

2. During growth, when root development is poor, fertilizer and water are insufficient, light is poor, plants grow leggy, or reproductive growth is poor, deformed fruits and split-lobed fruits are also very likely to form.3. When temperatures are relatively low during the fruiting period, roots have difficulty absorbing phosphate fertilizer, and anthocyanin levels are very likely to become too low, causing purple spots to appear on the fruit.

II. Solutions

1. Lower temperature and control humidity during growth

So during the growth of peppers, temperature should be controlled and humidity reduced. During the day, the temperature should be kept between 25-28 degrees; at night, it should be kept between 15-18 degrees; and air humidity should be maintained between 60%-70%. Only in this way is it favorable for pepper fruit growth and development and helpful for increasing yield and quality.

2. Increase temperature and retain heat in the late growth stage

In the late growth stage of peppers, temperatures are relatively low and light is weak and short, so measures such as keeping warm, preventing cold damage, and increasing light should be taken. At the same time, fertilizer and water management should be strengthened, more phosphorus and potassium fertilizer should be applied, and potassium dihydrogen phosphate foliar fertilizer should be sprayed to provide sufficient nutrients for fruit growth and development and promote normal fruit development.

3. Coordinate reproductive growth and vegetative growth

In the late growth stage of peppers, reproductive growth and vegetative growth proceed together. If too much nitrogen fertilizer is applied, it will cause the plants to grow leggy, normal vegetative growth will exceed reproductive growth, and normal fruit development will be poor. So during the flowering and fruiting period, fertilizer and water should be strengthened, more phosphorus and potassium fertilizer should be applied, and little or no nitrogen fertilizer should be applied. In addition, watering should also be given attention: flood irrigation should not be used, and at the same time, appropriate intertillage and loosening of the soil should be carried out to improve soil permeability.
