1. Soil Preparation and Fertilization: Remove crop residues 15-20 days before planting, and thoroughly till the field to break up the stubble. Apply well-decomposed farmyard manure (such as chicken, cow, horse, or sheep dung) at a rate of 3-4 cubic centimeters per mu. Mix it with 70% of the compound fertilizer and chemical fertilizer, then spread it evenly using a shovel. This ensures good nutrient distribution and improves soil structure. 2. Field Layout and Trenching: After fertilizing, prepare the beds with a width of 1.2-1.3 meters. Create a central furrow that is 40 cm wide and 30 cm deep. Place the excavated soil on both sides of the bed for easy access and better drainage. 3. Preparing Kampo Bacteria (Fermentation Agent): For each greenhouse, use 4 kg of warming agent (4 bags), 40 kg of wheat bran or rice sugar. In a typical 60m x 7m shed, use 3 kg of bacteria, 30 kg of wheat bran or rice sugar. The fresher the materials, the better. Mix 1 kg of bacteria with 10 kg of rice sugar and blend thoroughly. Add about 8 kg of water to achieve the right moisture level—when squeezed in your hand, it should hold a few droplets without dripping. Let it ferment at 20-25°C for 12-24 hours for optimal results. 4. Straw and Fermentation Agent Application: Spread the prepared corn stalks flat into the trench, compact them evenly along the edges. First, spray the straw surface with a 2% urea solution to moisten it. Then, evenly spread the fermentation agent over the straw and mix with a metal rake to ensure even distribution. Press gently to help the bacteria penetrate the straw layers. It's recommended to mix 1-2 parts of chicken manure (or other livestock manure) with the remaining 30% of the compound fertilizer. This mixture enhances soil fertility and lasts over a year. You can also place some of the mixture between the straw layers, but avoid overuse. 5. Covering with Soil and Watering: After applying the straw, bacteria, and fertilizer, cover the area with soil. Use 90% of the excavated earth to cover the straw, ensuring a layer of about 20 cm thick. This creates a raised bed or "high sorghum" effect. The remaining 10% of the soil can be used to build slightly raised paths for easier access and irrigation. Water the area thoroughly after covering, and re-water 2-3 days later to keep the straw moist. This prepares the bed for planting. 6. Planting and Drilling: When planting, dig small trenches or holes, spacing the seedlings 5-10 cm away from the edge. Before planting, add biofertilizer, fungicides, and insecticides into the trench, then water it. Immediately after planting, drill small holes into the soil pile using a 3 cm thick wooden or steel rod. Drill diagonally through the straw layer to a depth of about 15 cm. This improves air circulation and helps release carbon dioxide, promoting healthy root growth.
