How to manage colorful bell peppers for high yields? A detailed guide to the latest management methods

Colorful bell peppers are a type of sweet pepper, named for their bright, multi-colored appearance. Currently, colorful bell peppers fetch a good price on the market. If farmers want to earn higher returns, they need to find ways to increase yields, and this will naturally raise their returns. So how should they manage the crop to achieve high yields? Let's take a look together.

1. Dense planting, sparse branches

In colorful bell pepper management, retaining the main fruiting branches is key. The number of main branches to keep depends on the planting spacing. Generally, colorful bell peppers are planted at a spacing of about 54-55 cm, and 4 fruiting branches are selected and retained. However, if the spacing is set at 47-48 blueberries, only three main branches are retained. Although the spacing is smaller, the lower part is relatively dense, and each main fruiting branch occupies a relatively larger space. The plant's light exposure is much better than with four main branches, and the most important thing for plant growth is photosynthesis. When light exposure is good, photosynthetic efficiency is higher, so yields will naturally be higher.

2. Raise the temperature to promote color change

Colorful bell peppers are a warmth-loving crop. During the color-changing period, they are quite strict about temperature. Generally, keeping the greenhouse temperature between 28-30 degrees during the day is conducive to color change, but once it exceeds 33 degrees or falls below 20 degrees, color change will be affected. Therefore, during the color-changing period, special attention should be paid to temperature regulation, and the greenhouse temperature can be appropriately raised to promote color change. According to weather changes, the straw curtains can be pulled up later and lowered earlier. On cloudy and rainy days when light is weak, artificial supplemental lighting can be used, which will also raise the greenhouse temperature. After each fruit harvest, prune and trim branches as you go, thinning out excess branches and leaves to increase air and light penetration. This is beneficial for color change and also reduces unnecessary nutrient consumption.

3. Rational fertilization

Everyone knows that colorful bell peppers have a relatively high demand for potassium fertilizer during the fruiting period. Potassium fertilizer sowing will cause problems such as dull fruit color, poor glossiness, thin skins, and light weight. However, when fertilizing, potassium fertilizer should not be applied alone, so fertilization should alternate balanced fertilizer and potassium fertilizer to ensure the supply and balance of nitrogen, phosphorus, and potassium. In addition, colorful bell peppers like moisture and fear waterlogging. When watering and flushing fertilizer, the amount of water must be well controlled to prevent excessive water from causing root oxygen deficiency and root rot, which would affect normal growth. For greenhouse cultivation, drip irrigation is generally recommended, as this ensures the plants are not short of water and does not cause water accumulation.

4. Prevent pests and diseases

Greenhouse temperatures are relatively high, so pests and diseases also enter their peak period. If control is not timely, it can easily affect the fruit quality and yield of colorful bell peppers, such as the common thrips, red spiders, mites, blight, and powdery mildew. They can cause leaves to turn yellow and wrinkle, seriously affecting the plant's photosynthesis, so pest and disease control must be done in advance. For pest and disease control, use the right remedy for the problem. For example, thrips can be controlled with pesticides such as Spinetoram, spinosad, and imidacloprid, while red spiders can be controlled with pesticides such as spirodiclofen and thiamethoxam. When spraying, it should be thorough to improve the control effect.
