In 2002, Wei Yange, a farmer from Nianzigou Village in Dachengzi Town, started growing sweet peppers in a 50-meter-long greenhouse. By adopting new seed varieties, advanced technologies, and innovative cultivation methods, he achieved significant economic returns. His yield reached 5,500 kilograms per 667 square meters, with an income of nearly 10,000 yuan. Below are the key techniques he used:
First, selecting high-quality new varieties. He introduced Luodan sweet pepper seedlings from Hazela High Quality Seed Company in Israel. This variety is known for its strong growth, resistance to tobacco mosaic virus, and ability to thrive in cold conditions. It produces large, rectangular fruits with thick flesh, smooth skin, and vibrant color, ranging from green to red when ripe. Each fruit can weigh up to 800 grams, making it ideal for transport and market sale.
Second, preparing the land and applying proper fertilizers. Before planting, the soil was tilled to a depth of 40 cm and mixed with 10,000 kg of farmyard manure, along with urea, potassium nitrate, ammonium sulfate, and superphosphate. A disinfectant solution containing carbendazim and phoxim was applied to the soil surface to prevent diseases. Afterward, raised beds were formed, and micro-sprinkler systems were installed. The beds were covered with plastic film to maintain optimal moisture and temperature.
Third, field management after planting. Seedlings were transplanted on August 15, using a double-row system with spacing of 60 cm between small rows and 45 cm between plants. A total of 1,800–2,000 plants were planted per 667 square meters. Temperature control was crucial, with daytime temperatures kept between 26–28°C and nighttime temperatures between 15–20°C. Proper humidity levels (60–70%) were maintained, and the greenhouse film was regularly cleaned to improve light transmission.
Fertilization and irrigation were done every 7–10 days after transplanting. A mixture of potassium dihydrogen phosphate and broad-spectrum bactericides was sprayed to promote plant health. Water and nutrients were applied at a rate of 5 kg of nitrogen, 3 kg of phosphorus, and 9 kg of potassium per 667 square meters. Air circulation was managed by releasing ventilation twice daily to reduce humidity and improve climate control.
Plant training involved using bamboo stakes to support the vines and ensure even distribution of branches. Pruning was essential—axillary buds and lower diseased or yellow leaves were removed to enhance air circulation and light penetration. This helped prevent lodging and improved overall plant health.
Disease and pest prevention was prioritized. Before planting, poisoned bait was placed on the greenhouse floor to deter underground pests. Afterward, fresh soy milk activators were sprayed every 7–10 days to boost plant nutrition and prevent viral infections.
Finally, harvesting was done as soon as the peppers reached full size, had a rich color, and showed a shiny surface. Harvesting with scissors was recommended to avoid damaging the plants. Farmers like Wei Yange demonstrated that combining modern agricultural practices with careful planning can lead to substantial profits and sustainable farming.
