The latest course on management techniques and methods of color conversion period of sweet pepper

Sweet pepper is a kind of pepper, also known as persimmon pepper, big pepper, lantern pepper, its fruit is larger, spicy light or even not spicy, so it is generally eaten as a vegetable, not as a seasoning. It is very important for sweet pepper to change color when it is planted, and its body shape is related to the variety of sweet pepper, so how to manage it in sweet pepper color conversion? Let's take a look.

1. Temperature

First of all, we should pay attention to the temperature, sweet pepper in the color conversion of the temperature requirements are more strict, the daytime temperature is suitable at 28-30 degrees, if the temperature is too high, it will lead to difficulties in the formation of pigment, resulting in uneven color conversion, poor brightness. When planting, it is necessary to strengthen ventilation, set up sunshade net and spray cooling agent to reduce the temperature of the shed and make it change color normally.

2. Lighting

In the color conversion of sweet pepper, the light condition is very important, insufficient light will lead to uneven color conversion, but it is not suitable for direct exposure to strong light, because if the light is too strong, the strong light directly shines on the fruit, which is very easy to cause sunburn fruit. When the light is too strong in summer, sweet pepper only needs a certain amount of scattered light to meet its color conversion demand, so when changing color, it is not appropriate to remove the leaves near the fruit, but to keep the leaves properly to avoid sunburn fruit. As for the lack of light conditions, it is necessary to wipe the greenhouse film frequently, increase the transmittance of the greenhouse film, remove the old leaves and yellow leaves in time, increase the light transmittance between plants, and make their color change evenly.

3. Fertilizer and water

When planting, many vegetable farmers think that watering will affect the color conversion of sweet pepper, so in the color conversion of sweet pepper, it reduces the watering times and water quantity, which leads to the lack of water in the plant, which can not supply nutrients in time, forcing the plant to change color quickly. there will be dark fruit color, thin peel, low yield. When the sweet pepper changes color, it should be watered reasonably according to the plant growth and the dry and wet condition of the soil. Watering can increase the wetness of the field and reduce the temperature. When watering, potash fertilizer can be dissolved in water and watered together, which can increase the yield and promote the color conversion of sweet pepper to normal.

4. Spraying lycopene

Many in planting, in order to make the fruit color brighter, better quality, in the color conversion period, generally spray chemicals to speed up the color conversion of sweet pepper. This agent is lycopene, when spraying, we must pay attention to the concentration, not too high, otherwise its ethephon concentration is too high, it will lead to plant aging and premature senescence.
