First, the built-in straw bio-reactor technology points 1. Time: 2 to 4 months each year. 2. Dosage: Each kilogram of 1/15 hectare (1 mu) straw used 3000 to 4000 kg of 4 kg of bacteria. . 3. Mixture production: The bacteria, intermediate material and water are mixed into a mix. If wheat bran and rice bran are used as intermediate material, the three are to be seeded at 1:25:20. Such as the use of crushed corn cob, peanut shells as an intermediate material, the three by 1: 50: 70 seed dressing. It can be used after 2 days. 4. Method: Open the ditch immediately after planting in the early spring and open the ditch. Generally, the ditch width is 60 cm and the ditch depth is 30-40 cm. The ditch length is equal to the length of the ditch. After the ditch is opened, put straw or cattle and sheep dung in the ditch. The types of straw are not limited, the bottom is placed with a rigid whole stalk, and the soft crushed straw or cattle and sheep dung is placed on the top. The thickness is 40 centimeters (full of more than ditch) after being practicable. Then the mixture is evenly withdrawn on the top of the straw, and then the vibration is repeated once with a shovel, the mixture enters the straw layer, and then both sides of the soil are backfilled into the straw. The backfill thickness of the soil is 20 cm, after all the filling is completed. Water irrigation, drying for 4 to 5 days, drilling, to increase oxygen to promote the reaction, aperture 2 cm, hole spacing 30 cm, hole depth to penetrate the straw layer, generally 60 cm wide groove hit 3 rows of holes . Secondly, the remaining soil in the built-in trench will be excavated, and the planting line and the slope of the back slope will be set to 30 for soil preparation, so that the plum vines climb along the slope toward the ridge back. Finally, the cover film warms up. 5. Colonization: Colonization can be performed when the temperature of the upper 20 cm soil layer of the reactor reaches 16°C or more. Its methods include single colonization and double colonization. The single plant spacing was 30 cm, and the double plant spacing was rib centimeters. After returning, two holes are drilled for each strain, and the holes are to be separated from the melon seedlings by 8 to 10 cm. Other field management is the same as conventional management. Second, the simple external method of application of straw bio-reactor in the field or the appropriate place to dig a 5 to 6 meters long, 60 to 80 cm wide, 60 cm deep ditch, with a width of 2 meters wide, 7 meters long, thickness 7 to 8 silk agricultural film laying, made of a groove-shaped agricultural film ditch, in the ditch pressure film every 50 cm horizontally placed a wooden stick or cement pole, and then every 20 cm in the longitudinal direction of the bar fixed Iron wire, a separation layer is formed on the ditch, straw is laid above the layer, and each layer of 50 cm high straw is uniformly withdrawn. One layer of bacteria is evacuated. Generally, 3 layers can be filled and inoculated continuously, followed by watering, 1 kg. Dry straw needs to add 2 kilograms of water, after the straw is fully wet, the water in the ditch below is full 2/3, indicating that the straw has reached the standard of water absorption, and finally, after the cover film has been fermented for 8 to 10 days, the water in the reactor needs to be supplemented to open the reactor. Membrane, pump the water in the ditch below to the reactor. If there is not enough water in the ditch, add water from other places, fill in the agricultural film, and add water once every 8 to 10 days. The liquid leached from the reactor can be pumped out of the root and sprayed. Irrigating roots 1 to 2 times a month, spraying leaves 2 to 3 times.
