How to promote color change in bell peppers? Introduction to common methods
What methods are there to promote color change in bell peppers? Please give guidance. There are four methods to promote color change in bell peppers: 1. Through topdressing, supplement potassium fertilizer and boron fertilizer, and do not use excessive nitrogen fertilizer. Usually the amount of potassium fertilizer is about 1.5 times the amount of nitrogen fertilizer. This promotes color change in bell peppers and gives good color. 2. Improve light conditions and avoid insufficient light...

There are four methods to promote color change in bell peppers:
1. Through topdressing, supplement potassium fertilizer and boron fertilizer, and do not use excessive nitrogen fertilizer. Usually the amount of potassium fertilizer is about 1.5 times the amount of nitrogen fertilizer. This promotes color change in bell peppers and gives good color.
2. Improve light conditions and avoid insufficient light. Sufficient light is one of the important measures to promote coloring in bell peppers. During the coloring period of bell peppers, be sure to frequently wipe the greenhouse film to increase its light transmittance. Old leaves and yellow leaves on the lower part of the plants should be removed in time to ensure good light penetration and ventilation between plants and promote uniform coloring of bell peppers.
3. Increase the temperature difference between day and night to increase the accumulation of photosynthetic products. But also avoid temperatures that are too high or too low, such as above 30°C and below 12°C.
4. A coloring agent can be sprayed, but the concentration must be low. Otherwise, the high concentration of ethephon in it will cause plant aging. It should be sprayed at no more than a 3000-fold dilution of 40% ethephon, and the concentration for fruit coating should also not exceed 300-fold.
