Detailed Explanation of Chili Pepper Planting Time and Management Techniques

SummaryPlanting time: the better sowing period in spring and early summer is from March to July. Land preparation and base fertilizer application: deep plow the soil 10-15 cm, apply about 5000 kg of barnyard manure and 15-20 kg of superphosphate. Seedling raising and transplanting: after the seedlings emerge, water the seedbed in the morning on a sunny day, and transplant in the afternoon. Field management: before harvest, water lightly and apply an appropriate amount of phosphorus and potassium fertilizer. Pest and disease control: before planting, spray with 800 times diluted Xin Gaozhi Mo solution for disinfection.

I. Planting Time

1. The planting time of chili peppers needs to be determined according to local climatic conditions. Since chili peppers are heat-loving by nature, the better sowing period in spring and early summer is from March to July.

2. Generally, appropriately early sowing will promote fuller growth of chili peppers and help produce several more rounds of chili peppers. When sowing chili peppers, there is no need for pre-germination treatment; they can be sown directly. During this period, bury the seeds completely and then water thoroughly.

II. Land Preparation and Base Fertilizer Application

Choose a plot that is convenient for irrigation and drainage and has loose soil. Generally, before planting, deeply plow the plot to a depth of 10-15 cm, and at the same time apply sufficient base fertilizer. During this period, apply 5000 kg of barnyard manure and 15-20 kg of superphosphate, and open ditches to prevent water accumulation and facilitate irrigation.

III. Seedling Raising and Transplanting

1. Early-maturing varieties can be sown in January, while late-maturing varieties can be sown in February to March, and then transplant after the seedlings emerge. Generally, it is necessary to water the seedbed in the morning on a sunny day and transplant in the afternoon.

2. For early-maturing varieties, the suitable row spacing is 40-50 cm and the plant spacing is 26-33 cm, with 1-2 seedlings retained per hole, while for late-maturing varieties, the suitable row spacing is 66-73 cm and the plant spacing is 50-60 cm, with 1 seedling retained per hole.

IV. Field Management

1. Generally, before harvesting chili peppers, water lightly and apply fertilizer early. Combined with cultivating, apply an appropriate amount of phosphorus and potassium fertilizer to promote healthy seedling growth and prevent flower drop, and at the same time remove the side branches on the main stem below the first flower.

2. When entering the harvest period, harvest chili peppers early, and water and earth up in time, and apply fertilizer. In high-temperature seasons, water in the morning and evening, which helps maintain soil moisture, and apply only a small amount of chemical fertilizer.

V. Pest and Disease Control

1. Common pests and diseases of chili peppers include bacterial wilt and powdery mildew. Generally, for the control of bacterial wilt, first select disease-resistant varieties, and in the early stage of onset, spray the soil with 100-200 ppm agricultural streptomycin diluted with water. It can be sprayed continuously 3 times, and root irrigation every 10-15 days, continuously 2-3 times.

2. For the control of powdery mildew, first select varieties with good disease resistance. Before planting, spray with 800 times diluted Xin Gaozhi Mo solution for disinfection. In the early stage of onset, spray with 1000 times diluted Duoyangqing solution plus 3000 times diluted DuPont Fuxing solution for control.
