Sowing time and area are crucial for growing vegetable soybeans. From now until the end of July, it's an ideal period to sow in the province, as yields tend to be high and the economic returns are favorable. In the Huaibei region, sowing should be completed before July 20th, while areas south of the Huai River can be planted by the end of July.
Choosing early-maturing varieties is essential for maximizing yield and quality. Recommended varieties include "New Liuqing" developed by the Anhui Academy of Agricultural Sciences, as well as Tezao 1, Hefeng 25, and others that have shown good performance in local conditions.
Cultivation techniques play a key role in successful soybean production. First, apply fertilizer early after seedlings emerge, using a cultivator to promote growth. A second application of urea should be made when flower buds appear, and foliar fertilizer can be applied during the flowering stage to enhance plant health.
Increasing planting density is another important practice. The recommended seeding rate is about 6 kg per mu, with 4 to 5 seeds per hole, aiming for around 20,000 healthy plants per mu.
Field management should be thorough. Regular weeding and soil cultivation help maintain healthy growth. Watering should be controlled before harvest, but irrigation is necessary during dry periods, especially during the flowering phase.
Pest and disease control is critical. Common pests include aphids, leaf miners, red spider mites, Spodoptera litura (fall armyworm), and bean pod borers. Aphids, leaf miners, and spider mites can be managed using *Aphytus versicolor* and *Fructus lycii*. For Spodoptera litura and bean pod borers, bio-pesticides like *Bacillus thuringiensis* (Bt) are effective, with a second treatment required after 10 days.
Diseases such as viral infections, rust, powdery mildew, downy mildew, and purple spot can also affect soybean crops. Viral diseases are often spread by aphids, so spraying a virus emulsion at a dilution of 800–1000 times is recommended, followed by a preventive spray after 7 days. Rust and powdery mildew can be treated with triadimefon or zeocin, while downy mildew can be controlled using chlorothalonil.
Harvesting should be done at the right time. Soybean pods mature gradually from bottom to top, so it's best to pick fully developed, still-green pods. Multiple harvests may be needed, with the final one completed once all pods are mature. This ensures the highest quality and yield.
