How to manage the color conversion period of sweet pepper? Please give guidance to sweet pepper color conversion period management can refer to the following methods: first of all, we should pay attention to ensure a reasonable temperature. The color conversion period of sweet pepper has strict requirements on temperature, and it is most favorable for sweet pepper to change color when the greenhouse temperature is 28 ℃ and 30 min during the day. However, recently, the temperature in the greenhouse is often more than 40 ℃, which makes it difficult to form sweet pepper pigment, resulting in incorrect color and poor brightness of sweet pepper after changing color. Vegetable farmers should increase ventilation, sprinkle mud, spray cooling agents, set up sunshade nets, etc., reduce the temperature in the shed and ensure normal color conversion. Vegetable farmers should pay attention to the side wind, should first install a 40-50 cm wide film around the arch shed to prevent sweeping wind in the shed, so that sweet pepper color conversion period is easy to appear chapped skin. Second, do not remove the leaves around the color-changing sweet pepper. Because of the strong light, the fruit is vulnerable to damage when exposed to direct sunlight, and even produces sunburn fruit.

Third, replenish water and fertilizer in time. Many vegetable farmers think that watering will affect the color conversion of sweet pepper, so it reduces the watering times, which makes the plant lack of water and nutrition, forcing sweet pepper to change color faster, but the fruit color becomes darker, the pericarp becomes thinner and the yield decreases. Vegetable farmers should according to the growth of sweet pepper reasonable watering (through watering can also reduce the temperature in the shed), increase the use of potassium fertilizer, promote the normal color conversion of sweet pepper, vegetable farmers can apply high potassium fertilizer per mu with water, such as fragrant run 5-10 kg.
