Chili peppers are one of China's important vegetable crops, with numerous processed products and a long industrial chain, giving them high economic value. Currently, chili peppers are grown throughout most of China, both north and south. So, what is the typical yield of chili peppers per mu (approximately 0.16 acres)? Let's find out below.
What is the typical yield of chili peppers per mu (unit of land area)?
Under normal circumstances, the yield of chili peppers is about 500-800 kg per mu (approximately 250-300 catties per hectare), or about 1000-1600 jin (approximately 500-800 kg per hectare). However, if high-yielding varieties are selected and scientific planting management is implemented, the yield per mu can reach 1000 kg or even higher.
What are some techniques for high-yield chili pepper cultivation?
1. Soil improvement
Because chili peppers have relatively weak root systems, planting sites should be selected in sunny, neutral or slightly alkaline, well-drained, and fertile soil. If the soil is too acidic, it can be neutralized by sprinkling lime powder; if it is too alkaline, it can be neutralized by mixing in cinders.
2. Select the right planting location
Besides avoiding continuous cropping with other crops, chili peppers should also avoid continuous cropping with melons, eggplants, potatoes, and tomatoes . Continuous cropping will inevitably lead to reduced yields and make them more susceptible to pests and diseases. Therefore, it is essential to choose the right cropping sequence when planting chili peppers. The most suitable cropping sequence is after scallions and garlic.
3. Sowing and seedling raising
Soak the seeds in warm water for 8 hours before sowing, then wrap them in damp gauze to promote germination. Sow when 70% of the seeds show signs of sprouting. Do not water the seedlings before they emerge from the soil. After emergence, water them every 5 days. If the seedlings are weak, you can water them with a 0.5% urea solution . This will help us cultivate strong chili seedlings.
4. Reasonable planting density
To make full use of space, a management method of dense planting in the early stage, thinning of plants in the middle stage, and thinning of branches in the later stage can be adopted, with the goal of avoiding overcrowding of leaves and branches, thereby improving the total yield and overall benefits. It is generally recommended to control the planting density at 3,000 holes per acre, with 1-2 seedlings per hole, a row spacing of 50-55 cm, and a plant spacing of about 25-30 cm.
