The practice: First, the preparation before modulation 1, preparation of conical drying stand: According to the number of cones, stacked 90 pounds per square meter of cones proportion, set off the open air conical drying stand. Taiwan can be 30 cm high. 2, prepare the seed to modulate the greenhouse: in the greenhouse, take the long direction to set up the seed to deal with the frame, the frame length is not limited, width is suitable for 1.5 meters, Eli turn. According to the general level of the greenhouse each take 3-4 layers, the ground floor generally 1.5 meters, the rest of each
