Causes of Low Yield in Autumn-Winter Season Peppers and Solutions
Peppers are one of the common vegetables in our daily lives, and in many regions people cannot go without them for all three meals a day. Although it is now the autumn-winter season with lower temperatures, quite a lot of people still grow peppers. Many growers have found that autumn-winter season peppers have relatively low yields. What is going on here? Let's take a look together.
I. Causes of Low Yield in Autumn-Winter Season Peppers
1. During the growth process, factors such as poor root development, insufficient fertilizer and water, and poor light easily lead to deformed fruits and split-lobed fruits, seriously affecting pepper yield and quality.
2. In autumn, when fertilizer is applied, the temperature turns cooler, but sometimes the temperature is still relatively high. If peppers encounter a high-temperature, high-humidity environment during the flowering and fruiting stage, and then low temperatures and scant light in the late growth stage, pollination cannot proceed properly, resulting in a low fruit-setting rate, and naturally the yield will decline.
3. When temperatures are relatively low during the fruiting stage of peppers, the roots have difficulty absorbing phosphorus fertilizer, which easily leads to low anthocyanin synthesis, causing purple spots to appear on the fruits and seriously affecting pepper quality.
II. Solutions
1. Lower temperature and control humidity
During the growth period of peppers, the temperature should be lowered and humidity controlled. During the day, keep the temperature between 25-28 degrees, at night keep it between 15-18 degrees, and maintain air humidity between 60%-70%. Only in this way can the growth and development of pepper fruits be favored, helping to improve yield and quality.
2. Increase temperature and preserve moisture
In the late growth stage of peppers, temperatures are relatively low and light is weak and short, so measures should be taken to increase temperature, protect against cold, and increase light. At the same time, fertilizer and water management should be strengthened, with increased application of phosphorus and potassium fertilizers, 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 advance side by side. If too much nitrogen fertilizer is applied, it will cause peppers to grow excessively, causing vegetative growth to exceed reproductive growth and resulting in poor fruit nutrition. Therefore, during the flowering and fruiting stage, fertilizer and water management should be strengthened, with increased application of phosphorus and potassium fertilizers, little or no nitrogen fertilizer, and watering should not be done by flooding. Appropriate intertillage and soil loosening should be carried out to improve soil permeability.
